Audi is entering into a new market segment. With the Audi Q2 Audi is introducing an SUV that rounds out the Q family downward in size. At a length of 4.19 metres, it combines a youthful design with a high level of functionality and plenty of driving fun. Connectivity, infotainment and assistance systems come from the luxury class. The compact SUV is built at the main Audi plant in Ingolstadt, and it will launch on the European market in autumn 2016. The Audi Q2 presents a powerful and energetic image at first glance. Two large, powerfully contoured air inlets and the highly positioned Singleframe radiator grille clearly give the front end an SUV look. In a side view, edges and polygons accentuate the vehicle’s lines in a design language that is new at Audi.

A special feature is the color-offset blade on the low-profile C-post that can be customised. Above the high shoulder line are the narrow windows which make up around one-third of the surface area relative to the metal surfaces. The flanks are drawn inward in the door area. They emphasise the wheels and with them the quattro character of the compact SUV. At the rear, a long roof spoiler, the strong curvature of the bumper and the diffuser in underbody-protection look create a dynamic finish. On the left side the exhaust system terminates in single or twin tailpipes. Just like the wedge-shaped headlights, the rear lights can also be implemented in LED technology as an option. Audi can also supply dynamic turn signals at the rear.

Body

Suspension

The body creates the foundation for the vehicle's rigorous lightweight design concept. Form-hardened steels give the passenger cell a strong backbone. A roof slopes gently rearward toward the C-pillar with its contrasting-colour blade. As an option, the vehicle can be equipped with an electric rear lid drive.

A McPherson strut-type axle is used at the front. quattro models have a multi-link rear axle, while front-wheel-drive models have a torsion beam axle. Adaptive dampers are optional. Progressive electro-mechanical steering (EPS) and the electro-mechanical parking brake (EPB) are standard. For the first time on an Audi model, an ACC system by Continental AG is available as an option. A wide selection of wheels in sizes ranging from 16“ to 18“ offers lots of scope for customisation.

Power transmission

Electrical system and electrics

In addition to the well-known six-speed manual gearboxes as well as the 0CW and 0D9 dual-clutch gearboxes, there is the newly developed sevenspeed dual-clutch gearbox 0GC which can be used for both front and allwheel drive. The 0BR rear axle drive with all-wheel-drive clutch or the 0CQ rear axle drive with all-wheel-drive clutch are used for the quattro drive depending on engine version. Both final drives house the 0CQ all-wheel-drive clutch. This is the fifth generation of the electro-hydraulically controlled allwheel-drive clutch.

The electrical system of the Audi Q2 is based on the electrical system architecture of the Modular Transverse Matrix (MQB). There are many similarities with the electrical system architecture of the Audi A3 (type 8V) PA. Special features of this electrical system architecture are: • The battery is to be found in the engine bay on all Audi Q2 models. • There is no FlexRay bus system like in Audi Q2 models. • The MOST150 bus system is used. Two spindle drive units are used in models with electric rear lid drive.

Body Introduction The body of the Audi Q2 is based on the Modular Transverse Matrix. Previously used in the Audi A3 (type 8V), this reliable platform has been adapted to meet the specific requirements of the Q2 with a wheelbase of 2595 mm. The weight target for the Q2 of 1250 kg (model with 1.0l TFSI engine) and the exacting demands on vehicle safety were achieved by making systematic use of different material grade and particularly ultra-high-strength parts made of hot-shaped steel. The weight of the body cell (version with solid roof without attachments) is approximately 275 kg.

Joining technology A number of different joining technologies are used to assemble the body of the Q2. In addition to classic resistance spot welding (there are 2440 spot welds on the car), the following technologies are utilised:

In addition to that, 3681 mm of support adhesive and 31533 mm of structural adhesive are used in ever y body.

• MAG welding (total seam length: 1182 mm) • Laser soldering (total seam length: 3102 mm) • Plasmatron soldering (total seam length: 1273 mm)

Ultra-high-strength hot-shaped components The use of ultra-high-strength hot-shaped steel materials means that body repairs can only be accomplished by adopting special repair methods suited to the properties of the material in question.

High heat transfer to the surface to be welded would significantly diminish the strength and weaken the structure of the component by altering the microstructure of the material. For this reason, MAG inert gas welding may only be used for sectional repair work on these high-quality steels in isolated cases and in precisely defined areas. The relevant descriptions can be found in the workshop literature.

Sectional repairs and replaceable components Following miscellaneous trials and crash tests on the Audi Q2, approval was given for two sectional repair areas where MAG welding is allowed: 1 2

Partial tempering 24 % of the car body is made from hot-stamped steel. Prior to shaping, they are heated to about 1000 °C in a continuous-flow oven and then immediately cooled to about 200 °C in a watercooled pressing tool. This abrupt change in temperature creates an iron-carbon microstructure which imparts exceptional tensile strength. Components made from these high-end steels are relatively thin and therefore light. Components such as the rear side member or the inside B post have to be capable of absorbing and dissipating the forces that occur in the event of a crash and, therefore, are partially hardened and tempered in accordance with requirements. This gives the component high-strength or ultra-high-strength properties within a defined area.

Tailored Rolled Blank

The heel plate (6) has been adapted specifically to meet body strength and crash safety requirements by employing tailor rolled blank technology. These are flexibly rolled blanks, where variations in sheet-metal thickness are produced by controlled opening and closing of the gap between the rollers. These variations in sheet-metal thickness not only save weight but also create defined crumple zones which provide protection in the event side-on impact. The thickness of the sheet-metal at the heel plate varies between 0.95 and 1.70 mm.

Design and customisation Customisation is a key purchase reason for young, progressive customers and is made possible by offering trim lines, packages and a variety of options. Audi Original Accessories (AOZ) offers further customisation options for buyers ordering a new car

ex-factory or as a commercial retrofit solution. For example, various design decals are available for the Audi Q2 to accentuate its distinctive design features.

Blades on the C posts The C post on the Aud Q2 are trimmed with so-called blades consisting of an outer shell mounted on a carrier part. The blades are precisely positioned relative to the car body by means of centring pins (highlighted red in the illustration) and held in place by adhesive as well as a total of eight fastening clips per side. The blades represent not only a design highlight - they also enhance

the aerodynamics of the Audi Q2. The blades on the C posts can also be used for further customisation. They are available in body colour, in a contrasting colour or in other optional colours depending on equipment level. Blades are supplied to Customer Service with a primer coat applied. Fastening and sealing materials are also available separately.

Centring pins 654_014

Interior The customer can also custom-design the interior with a choice of eight different decorative inlays in three different materials. For

Dash panel The dash panel in split into top and bottom sections according to the layer concept. Depending on equipment level, the Audi Q2 is

fitted with different dash panel versions which differ from one another in terms of the following criteria: • Left or right hand drive • Analogue instrument cluster or Audi virtual cockpit • With or without head-up display

MMI display There is a trim around the opening for the MMI display in the centre of the dash panel. The trim comes in two different sizes depending on the width of the MMI display fitted.

Upper wrap-around trim for 8.3-inch MMI displays

Upper wraparound trim for 5.8 and 7-inch MMI displays

Upper trim support in the dash panel (identical in all versions)

Seats The Audi Q2 combines the high seating position typical of an SUV and the low seating position of the driver and front passenger characteristic of Audi models – that is to say, the mutual relationship between the seat, foot controls, steering wheel and dash

panel. This further underscores the dynamic and sporty character of the Q2. 60/40 split folding rear seats are standard. A three-way, 40:20:40 split folding rear seat is optional in the Q2. An armrest and a cupholder are integrated in the folded-down centre section.

Rear lid The Audi Q2 can have either a rear lid with manual closing and opening function or a power opening and closing rear lid (optional). Two spindle drives are installed in the Q2 for this purpose. To allow the rear lid to close reliably in all conditions, the articulation of the spindel drive relative to the body had to be modified compared to the gas-filled spring in the manual version.

The rear lid itself and the two bottom brackets are identical in both versions. The modified geometry of the upper bracket means that the angle of attack of the spindle drive relative to the body is different.

Power transmission Overview The design of the Audi Q2 (type GA) follows the principles of the Modular Transverse Matrix (MQB). Depending on engine-gearbox combination (refer to page 22), the Audi Q2 is available with frontwheel drive or with all-wheel drive. The proven quattro drive system is used for models with all-wheel drive. Either the 0BR rear axle drive with all-wheel-drive clutch or the 0CQ rear axle drive with all-wheel-drive clutch is used, depending on engine power output.

In addition to the well-known six-speed manual gearboxes and the 0CW and 0D9 dual-clutch gearboxes, there is 7-speed dual-clutch gearbox 0GC which can be used for both front and all-wheel drive. Refer to page 26.

The 0GC gearbox has the in-house designation DQ381-7F for front-wheel-drive vehicles and DQ381-7A for all-wheel-drive vehicles. The 0GC gearbox is rated for peak input torque of 420 Nm.

The key new features of the 0GC gearbox compared to previous gearboxes are principally aimed at increasing efficiency: • A horizontal hydraulic oil filter. • Friction-optimised bearings in the drive shafts and in the differential. • Friction-optimised seals in the rotary inlets for the clutches between the clutch cover and the gearbox input hub and in the drive shaft bearings. • An ATF with reduced viscosity reduces friction losses in the gear set.

• A leakage-optimised hydraulic system provides a low pressure level, with the result that less pump capacity is required. • An ATF supply with a twin-pump system Refer to page28.

Mechatronic unit J743

Gear set

The mechatronic unit of the 7-speed dual-clutch gearbox 0GC runs in an ATF oil bath. In terms of its design, it is largely identical to the mechatronic unit of 7-speed dual-clutch gearbox 0BT as described in SSP 454.

The gear set with sub-gearboxes 1 and 2 is largely identical to the gear set of the gearbox described in SSP 454 "The 7-speed dualclutch gearbox 0BT in the T5 2010".

Leakage losses have been reduced by using sliding seat valves. An additional pressure control valve N218 has been integrated into the hydraulic system. It controls the supply of ATF by auxiliary hydraulic pump 1 for gear oil V475. Refer to page 28.

Auxiliary hydraulic pump 1 for gear oil V475

The gear set, the dual clutches and the mechatronic unit J743 are share a common ATF supply. The mechatronic unit has its own oil reservoir, which is flooded with ATF up to the overflow rim. This means that all solenoid valves run in an oil bath, which ensures complete ventilation of the electro-hydraulic unit and cools the solenoid valve coils. The ATF level in the oil reservoir for the gear set is kept to a minimum in order to avoid unnecessary churning losses.

The auxiliary hydraulic pump V475 is a unit comprising the duocentric pump and an electric motor. The pump is supplied with electrical power via a separate 4-pin connector. The pump electronics receive their instructions from the mechatronic unit J743 via the powertrain CAN. If required, the pump assists with the following: • • • •

ATF supply to clutches K1 and K2 in start-stop mode. Clutch cooling with ATF. ATF supply to the shift hydraulics in coasting mode. Lubrication of the gear set andthe shafts with ATF.

hydraulically actuated 3/2 way valve, which is activated by the pressure control valve N218 integrated in the mechatronic unit J743. In the non-activated state, the switchover valve directs the flow from the auxiliary hydraulic pump into the high-pressure circuit of the mechatronic unit J743 and thereby assists in supplying the gearbox with hydraulic oil. If the switchover valve is activated via the pressure control valve N218, the flow from the auxiliary hydraulic pump is directed into the low-pressure circuit in order to cool the clutches and l ubricate the gearbox. The non-return valve which follows the 3/2-way valve is kept closed by high pressure applied in the reverse direction.

Main ATF pump The main ATF pump is driven permanently and mechanically via a gear which is connected directly to the dual clutches. The main oil pump has been made smaller and more efficient by reducing leakage losses through the use of sliding seat valves among other

things. To compensate for load peaks and to make possible functions such as start-stop mode or coasting mode, the main oil pump is assisted by the auxiliary hydraulic pump V475. The main ATF pump performs the following tasks: • Supply of ATF to clutches K1 and K2. • Clutch cooling with ATF. • Supply of ATF to the shift hydraulics. • Lubrication of the gear set and the shafts with ATF.

Gearbox functions and functions influencing the gearbox control unit Audi drive select

Other functions

Audi drive select can be used to select between different vehicle configurations, i.e. modes. The following modes are available in the Audi Q2: efficiency, comfort, auto, dynamicand individual . The gearbox setups are tailored to the customer's requirements in a country-specific fashion. For this reason, only typical differences between the various modes can be shown here. In efficiencymode the shift points for automatic gearboxes are shifted to lower engine speeds and coasting mode is available in drive position D, provided that the conditions for this are met (refer to owner's manual). This allows more fuel-efficient driving.

In addition to Audi drive select, the gearbox control unit participates in other vehicle functions. These include: • The kickdown function • Manual gear-shifting (tiptronic mode) • The Launch ControlProgram (available with 0GC / 0D9 gearboxes only) • Coasting mode • The start-stop system • Downhill assist

In the comfortand automodes, the gearbox shift points are comfort-oriented, well balanced and designed for everyday use.

These functions should be sufficiently well known. They serve partly to enhance comfort and partly to increase driving efficiency. You will find a description of these functions in the owner's manual.

Iin the sporty dynamicmode, the gearbox adjusts its shift points to higher up the rev band. In individualmode the driver can freely select an engine/gearbox setup irrespective of other vehicle systems under the Audi drive sel ect modes comfort, auto or dynamic.

Service Using the diagnostic tester The options for diagnosis of 7-speed dual-clutch gearbox 0GC and all-wheel drive clutch 0CQ are shown here.

The diagnostic functions can be accessed by selecting the relevant address code using the diagnostic tester.

Address code 0022 - All-wheel-drive electronics The all-wheel-drive control unit J492 can be selected with the diagnostic tester by entering address code 0022 - All-wheel-drive electronics, and the diagnostics results can be queried via all-

wheel-drive clutch 0CQ. In addition, the listed diagnostic functions can be used for assessment and handling of all-wheel-drive clutch 0CQ.

• Control unit identification

• Basic setting The basic setting function can be used to assign the all-wheel-drive clutch pump V181 to a matching characteristic curve stored in the all-wheel drive control unit J492.

• Check SVM control unit configuration The validity of the software, the coding and the adaption channels for the vehicle is checked. • Event memoryRead / Clear

• Read measured data • Replace control unit This function contains all steps necessary to replace the control unit.

• Actuator diagnostics To activate the actuator diagnostics, the internal combustion engine must be running, the ATF temperature must be under 60 °C and the vehicle must be at a standstill. If the actuator diagnostics are active, the all-wheel-drive clutch is kept closed until the vehicle reaches a speed of 6 kph. Driving the vehicle with the steering at full lock while the actuator diagnostics are active puts strain on the driveline, causing the rear axle to shudder. The all-wheel-drive clutch opens when the vehicle reaches a speed of 6 kph, noticeably relieving the strain on the driveline - an indication that the all-wheel-drive clutch is working.

Emergency operation of the all-wheel drive

Replacing the all-wheel-drive clutch pump V181

On theare printed circuit broadsensors of the all-wheel drive control unit J492 there two temperature which monitor the electronic components. The temperature of the clutch plates is calculated. Depending on which temperature threshold is exceeded, the all-wheel-drive clutch function is deactivated. This is not indicated to the driver by a warning lamp.

The first thing to do after replacing theoilall-wheel-drive clutch pump is to correct the all-wheel-drive level. A basic setting procedure must then be performed on the stationary vehicle and the oil level checked again. The final step is to run an actuator test.

Gearbox warning lamps

Towing

If the red gearbox warning light appears in the instrument cluster, the driver is instructed to stop the vehicle.

If the yellow gearbox warning light appears in the instrument cluster, it is normally possible to continue driving the vehicle. Driver information is displayed informing the driver what to do.

Note For detailed and up-to-date information, refer to the vehicle owner's manual.

If a situation arises where it becomes necessary to tow an Audi Q2 with automatic gearbox, the usual restrictions on automatic gearboxes apply: • Disengage the parking lock using the emergency release lever. Refer to page 25. • Selector lever in N. • Max. towing speed 50 kph. • Max. towing distance 50 km. • If the vehicle is to be towed with an axle raised, only the front axle should be raised. Reason When the engine is at standstill, the oil pump is not driven and certain parts of the gearbox are not lubricated. Failure to comply with the towing conditions can lead to serious gearbox damage. Note Note the other descriptions and notes on the topic of tow-starting and towing in the owner's manual.

Suspension Overall concept The suspension system of the Audi Q2 is based largely on proven technology used previously in other Audi models. Use is made of components and functions previously exclusive to higher-end models. A McPherson strut-type axle is used at the front. Models with quattro drive come equipped with a multilink rear axle. Front-wheel-drive models receive a torsion beam axle. The active suspension system with electronic damper control is the top-of-the-range option.

The Q2 also uses the electro-mechanical steering system (EPS) known from the Audi A3 (type 8V) and an electro-mechanical parking brake (EPB). Progressive steering is standard. A wide range of steering wheels, wheels and tyres is available for customisation. ACC is optional. Functions previously exclusive to higher-end models are, therefore, now available for the Audi Q2.

654_130

The Audi Q2 is available in front-wheel-drive and quattro all-wheel-drive versions. The following suspension variants can be ordered: Suspensionvariants

Axles and wheel alignment Front axle The front axle is based on that of the Audi A3 (type 8V). The steel subframe is a new development. The track control arms have been adapted to handle the higher axle loads of the Audi Q2. The bearing elements of the track control arms have been redesigned in terms of their elastokinematic characteristics. The plain bearings used in the Audi TT (type FV) are employed as suspension strut bearings.

654_131

Rear axle Front-wheel-drive models All front-wheel-drive models come equipped with a torsion beam rear axle. The basis for this is the axle of the Audi A3 (type 8V) with sport suspension. The requisite wider wheel spacing is achieved by using a newly developed kingpin.

654_132

Models with quattro all-wheel drive All quattro models are fitted with the multi-link rear axle of the Audi A3 (type 8V). By way of deviation from this, the wheel mounts of the Audi TT (type FV) are used (for a wider wheel spacing).

Wheel alignment and suspension setup 654_133

The wheel alignment and suspension setup is procedure us identical to that for the Audi A3 (type 8V). The setting points are also identical.

Dynamic Chassis Control (DCC) Dynamic Chassis Control (DCC) is optional in the Audi Q2. In terms of its design and working principle, the system is basically identical to the systems already in use on other Audi models. For the first time in an Audi, the system is also available in combination with a torsion beam rear axle. The damper control function is always engaged during vehicle operation and cannot be deactivated by the driver. The damper valves are not activated when the vehicle is at a standstill. The driver can set the damper characteristic with Audi drive select,

either using a separate switch in the switch panel or directly in the MMI. The last setting selected stay active after a terminal 15 reset. The electronic damper control system has 3 different damping characteristics. Depending on the setting chosen in Audi drive select, the system activates maps which provide a medium, comfort-oriented or sporty characteristic. The highest damping forces are produced when a current of about 1.9 A is applied.

Serviceoperations

If the control unit fails, if it is not possible to activate the dampers; and if no measurement data is supplied by two vehicle level sensors, the control system is shut down. The damper valves are designed in such a way that medium damping forces (basic damping) are produced in a neutral (nonactivated) state. The vehicle remains dynamically stable despite the corresponding loss of comfort. The system shutdown is indicated to the driver by the usual yellow pictogram (damper icon) and by a text message. If the signal from a vehicle level sensor is not available, a substitute signal is generated from the measurement data supplied by the other sensors and the control system stays active.

The Dynamic Chassis Control system can be accessed address code 0014 - Wheel damping electronics on the diagnostic tester. After a new control unit has been encoded online, the basic setting procedure must be carried out. For this purpose, the vehicle should be raised on the hydraulic lift far enough for the wheel to lose ground contact (dampers are fully extended). The measurement data supplied by the vehicle level sensors is assigned to the damper piston positions and stored in the control unit. After replacing a damper or a vehicle level sensor, the basic setting procedure described above must be carried out. The actuator diagnostics can be use d to perform a general function check. This damper valves are selectively activated and the actual and target current levels are indicated. A fixed differential amount may not be exceeded.

Brake system The Audi Q2 is equipped with a generously dimensioned brake system which offers high performance reserves in any driving situation. The electro-mechanical parking brake (EPB) and the ESC system are carry-overs from the Audi A3 (type 8V). In place of the Sport mode in the Audi A3, the Offroad mode can be activated in

Steering system The Audi Q2 is equipped with an electro-mechanical steering system (EPS). In terms of design, mode of functioning and service operations, the system is identical to that used in the Audi A3 (Type 8V). Special steering maps which can be activated with Audi drive select were developed. Likewise, the mechanically adjustable steering column is similar to that of the Audi A3 (Type 8V). An electrical adjustment is not available in this vehicle class. Electromechanical power steering (EPS) 654_137

Steering wheels The basic trim features a three-spoke PUR steering wheel. Audi also offers options for the Q2 (13 versions) ranging from a threespoke leather steering wheel to a three-spoke leather steering wheel with flattened rim, multifunction buttons and tiptronic.

adaptive cruise control (ACC) System overview An ACC system by Continental is used in the Audi Q2 for the first time in an Audi model. As with the ACC systems used prevously in Audi models, the control unit, sensor and receiver are integrated in a unit. The Audi Q2 uses a sensor unit which is located centrally at the bottom of the bumper. The control unit is connected to the front camera for driver assistance systems R242 via a private CAN (sub-bus system) and to the vehicle via the extended CAN bus. The

system is operated by the driver in the same way as in other Audi models. If the vehicle has Audi drive select, the ACC drive program is coupled to the setting selected here. Alternatively, the ACC can be custom-configured using theindividualsetting. If the vehicle is not equipped with Audi drive select, the ACC drive program is selected via a separate menu.

ADR sender, right G259 and ACC control unit J428 The sensor has two radar transmitter units and three receiver units. One receiver unit evaluates specifically the vertical signals. This gives a horizontal radar acquisition range of about +/- 45° at close range (up to approx. 40 m). The maximum range is approximately 170 m. The horizontal radar acquisition range is about +/-9° outside the close range. The reflector lens is not heated. The operating range of the ACC is 0 kph – 200 kph. A target speed can be set within the range from 30 kph to 200 kph.

ACC auxiliary functions The Audi Q2 has the following ACC auxiliary functions known from other Audi models: • Stop & Go ACC The Audi Q2 is ready to restart in three seconds. The extended restart readiness function implemented in several other Audi models is not available. ACC reacts to stationary objects. • Distance indicator / distance warning • Traffic jam assist The vehicle is guided longitudinally by the ACC system and transversely by the camera for driver assistance systems. In the Audi Q2 with traffic jam assist a measurement data from the ACC and camera is not combined like in the Audi A4 (type 8W) and in the Audi Q7 (type 4M).

• Control behaviour when cornering To avoid critical situations in terms of driving dynamics, cornering speed is not increased further by the ACC system during an acceleration phase, if necessary. The predictive route data from the vehicle navigation system is not evaluated by the ACC system in the Audi Q2. The Audi Q2 does not have predictive cornering speed control, as implemented for example in the Audi A4 (type 8W) and Q7 (type 4M) with ACC. The Audi Q2 controls uses vehicle dynamics data for speed control while cornering. 1) • Boost function 1) • Overtaking assistance

1) • Start-off monitoring Start-up of the Audi Q2 is monitored by evaluating the ACC radar signals only.

Service operations The components of the ACC system also have self-diagnostic capability in the Audi Q2. The ACC control unit J428 can be addressed with the diagnostic tester using diagnostic code 0013.

The system monitors the horizontal and vertical settings of the radar sensor (sender) on the basis of a statistical evaluation of objects detected. A key new service feature is that manual calibration of the sensors is no longer required. If misalignment of a sensor is detected by statistical evaluation, an offset value can be applied to the measurement data. At the same time, the system is able to compensate for misalignment values of +/- 6°. On completion of the work specified in the workshop manual (e.g. removal/installation of the ACC unit, adjustment of specific axle setting values), the reinstalled components must be calibrated at a wheel alignment workstation by following the usual procedure. The geometric drive axis of the vehicle is determined by an initial measurement. The reflector mirror of the setting device (VAS 6430/1 with ACC reflector mirror VAS 6430/10) is aligned at right angles to the vehicle. ACC is activated by the diagnostic tester. The misalignment angle is determined on the basis of the radar signals reflected by the reflector mirror. The ACC systems used previously in Audi models are set by the mechanic via the setting screws on the ACC unit. This work is no longer necessary in the Audi Q2. The ACC control unit determines the required correction factors and compensates electronically for the misalignment.

Electrics and electronics Power supply Car battery The battery of the Audi Q2 is housed in the engine bay and protected by a battery box. Battery size and type are dependent on engine version, trim and country specification. Standard batteries, EFB batteries and AGM batteries are used.

• All models without a start-stop system come fitted with a standard battery. • Models with a start-stop system come fitted with an EFB, irrespective of engine version. • Vehicles with an auxiliary heater generally come equipped with an AGM battery.

EFB battery

AGM battery

An EFB (Enhanced Flooded Battery) can be regarded as a heavyduty wet-cell battery. The positive plate inside the battery is coated with an additional polyester scrim. This provides additional hold for the active battery material. The deep-cycle resistance is higher than that of conventional batteries. An EFB is charged in exactly the same way as a conventional battery.

In AGM batteries, the battery electrolyte is bound in a microporous glass matting. In addition to having higher deep-cycle resistance than an EFB battery, the AGM battery is noted for its leak-proof construction. When charging an AGM battery, it is important to follow the charger's operating instructions and, where applicable, to program the charger for AGM batteries.

The following batteries are used on the Audi Q2: Standardbattery

The network diagram on pages 44/45 provides a schematic overview of the communication paths between the control units in the Audi Q2. As a further member of the MQB family, the Q2 cannot deny its close affinity to the Audi A3 (type 8V) or the Audi TT (type FV) in

regard to control unit networking. In spite of the many similarities with the A3 and the TT, there are a few differences. The Q2, for example, is the first Audi model in the MQB segment to be equipped with a head-up display.

Infotainment topology Digital sound package control unit J525

In the Audi Q2 up to 3 control units are integrated in the MOST ring in the following order: Control unit in instrument panel J285

• Information electronics control unit 1 J794 • Control unit in dash panel insert J285 • Digital sound package control unit J525

The launch of the Audi A3 (type 8V) also marked the introduction of the MOST150 in the area of infotainment. This optical bus system is also used in the Audi Q2. It has a data transfer rate six times faster than that of the MOST25 srcinally used by Audi. In the Audi Q2 the information electronics control unit 1 J794 acts both as the diagnostics manager and as the system manager for the MOST bus. This is a function previously performed by the data bus diagnostic interface J533. The J533 in the Q2 is a MOST bus user.

Audi drive select The Audi Q2 can be ordered with the Audi drive select system. The customer can choose between four operating modes:efficiency, comfort, auto and dynamic. The efficiencymode configures the vehicle for fuel economy and helps the driver conserve fuel. In addition, the car setup can be customised inindividualmode.

Depending on infotainment system, the Audi drive select system can be set either via a button on the centre console or via the CAR menu in the RMC/MMI.

Functional features • The mode previously selected is restored when the vehicle restarts. • The settings in individualmode are automatically assigned to the car key in use. • The mode can be changed whether the car is stationary or moving. Condition: terminal 15 "on"). • On some models, maximum speed is only achievable in theauto and dynamicdrive modes. • The individualmode is not available when towing a trailer. • To active the newly selected mode for the engine too, the accelerator must be briefly moved into the idle position.

Models with manual gearbox: • an E is additionally displayed on the gearshift indicator in efficiencymode. • If the accelerator is pressed down fully beyond kickdown at full throttle in efficiencymode, engine power output is automatically adjusted to provide maximum acceleration. Models with dual-clutch gearbox: • If the vehicle is running inefficiencymode, anE is displayed automatically in the instrument cluster when the selector lever is in D. • When dynamicmode is selected, the gearbox is automatically put into S. When efficiencymode is selected,E is engaged automatically.

Combiner head-up display The "head-up display" (HUD) is a display system which allows drivers to keep a largely unchanged head posture and/or line of vision because the information is projected into their field of vision.

Combiner head-up display

A combiner head-up display (cHUD) is used in the Audi Q2 for the first time in a Audi. The combiner is, as it were, a "combiner of information". Technically speaking, the front windscreen does not serve as the reflective surface for display of information but rather a small, transparent and reflective yet translucent glass screen. This screen is an integral part of the cHUD module and saves having to fit special windscreens.

654_083

Readouts on the combiner head-up display The virtual image which is projected onto the combiner screen by means of an optical system can display the following information within the driver's field of vision: • Warnings • Information from driver assistance systems, such as roads signs indicating speed limits • Vehicle speed • Navigation messages The brightness level of the display is adapted continuously to the brightness conditions. For the purpose, the windscreen projection control unit (head-up display) J898 evaluates the values generated by the rain and light detector sensor G397 and adjusts the display brightness level accordingly. The light intensity level is configured in such a way that the display stays easily legible both at night and in direct sunlight.

Function The kinematic mechanism of the combiner head-up display is driven by the display opening/closing motor J301.

Virtual image of the head-up display

Combiner screen

Field of view

The head-up display is implemented by back-lighting a TFT screen with a light source comprising multiple LEDs. The light beams are then projected onto the combiner screen via an internal folding mirror. Using an internal folding mirror in combination with the combiner screen creates the impression that the head-up display is not in the area of the combiner screen, but rather at a comfortable distance of 2 m – 2 ½ m from the driver. This effect is achieved by applying the physical laws of reflection and transmission to the combiner screen.

Air conditioning Overview The Audi Q2 (type GA) is available with different heating and air conditioning systems: • Manually regulated air conditioning system • Automatically regulated air conditioning system Depending on country specification, both versions may not always be available in certain markets. A new rain and light sensor G397 is used in the Audi Q2. The sensor has the following characteristics: As previously in other Audi models: • Rain detection • Light detection • Air humidity detection

There is also the efficiencymode (Audi drive select) for energyefficient operation of the air conditinoing system. This is displayed in the climatronic control unit J255. As throughout the entire vehicle, all the buttons on the control panel are illuminated in white. The Audi Q2 is delivered with the new E1234yf refrigerant. The changeover from R1234a to E1234yf affects all vehicles within the VW Group and is not model-dependent. The changeover currently affects only vehicles which are approved in the EU. With effect from 01.01.2017, it will no longer possible to register new vehicles with R134a refrigerant in Europe.

New features of the Audi Q2: • Sun detection The new additional functions are not visible from the exterior of the vehicle. The new sensor position is positioned in the base of the centre mirror. This eliminates the need for the previous sun sensor, the sunlight photosensor G107, in the dash panel.

Rain and light detector sensor G397

Dust and pollen filter The Audi Q2 features a new filter for the cabin air, which is available as an optional extra. These is available in two versions each consisting of three layers with a different working principle. The special feature is the new outer substrate layer, which also has an anti-allergenic effect. The existing two layers are key to the high air quality within the cabin. The filtration layer is constructed from special microfibres and filters fine dust particles out of the air. The activated carbon layer traps gaseous impurities.

The filter, the is to say the upper surface of the filter, is yellow. A yellow surface on the filter is therefore indicative of a new antiallergenic filter. The installation procedure, location and position are the same as for the Audi A3 (type 8V), i.e. in the footwell on the front passenger side, behind the glove compartment, in the air conditioner.

Active safety Audi pre sense Working within its system limitations, Audi pre sense is able to initiate actions to protect the occupants and other road users in certain critical situations. For this purpose, the vehicle and its occupants are prepared for a potentially imminent collision. This is made possible by networking various in-car systems. The systems

send data continuously to the data bus. Other control units are able to receive and evaluate this information and take appropriate action. Audi pre sense is available for the Audi Q2 in the following versions:

PR no. 6K2

This variant comprises Audi pre sense front withoutACC (Audi adaptive cruise control).

PR no. 6K4

This variant comprises Audi pre sense front includingACC (Audi adaptive cruise control).

PR no. VL0

In this variant the vehicle is

PR no.VL3

In this variant the vehicle is equipped with an "emergency braking function for pedestrians" (see function B: "Response to pedestrians" on page80).

PR no. 7W1

This variant includes Audi pre sense basic.

not equipped with an "emergency braking function for pedestrians".

Note: PR nos. VL0 and VL3 (with or without "emergency braking function for pedestrians") are country-specific equipment and therefore cannot be selected by the customer. Depending on country, Audi pre sense front may be standard without ACC and with "emer-

gency braking function for pedestrians" (PR nos. 6K2 and VL3). If customers wish to have ACC in these countries, they can order Audi pre sense front including ACC. In this case, the PR nos. are 6K4 and VL3.

Note Note that Audi pre sense acts within its system limitations and cannot always prevent collisions from occurring. It serves only to assist the driver and it can reduce the severity of the collision. Also note that not all objects can be detected by the radar sensor The individual functions of Audi pre sense are described in greater detail below.

Audi pre-sense basic With Audi pre sense basic, the following action can be taken: • Partial or full tensioning of the electrically reversible front seat belt tensioners

• Closing of the panoramic glass sunroof1) • Closing of the side windows

System characteristics of the reversible seat belt tensioners

Reversible belt tensioner with electric motor

• If an accident does not occur after a reversible tensioning (partial or full tensioning) of the seat belts, the seat belts are released again. The reversible seat belt tensioners are, therefore, ready to deploy again. • If a seat belt is not worn, this seat belt is not partially or fully tensioned. • If the front passenger airbag is "off", the seat belt is not partially or fully tensioned on the front passenger side. • Being LIN control units, the reversible seat belt tensioners, the front left seat belt tensioner control unit J854 and the front right seat belt tensioner control units J855 are connected to the airbag control unit. • Partial or full tensioning of the reversible seat belt tensioners can take place upwards of a speed of about 30 kph, both in terms of the longitudinal and transverse dynamics. An exception here is the crash function which is implemented at low relative speeds (refer to page76). • Reversible tensioning of the seat belts reduces the forward displacement of the front occupants in a crash. • The reversible seat belt tensioners cannot be deactivated via the MMI. This means that the reversible seat belt tensioners are effective even if Audi pre sense is switched off, provided that the conditions for deployment are met. 654_051

Longitudinal dynamics function Hazard braking If the brake pressure reaches a defined level during a hazard braking manoeuvre, Audi pre sense basic partially tensions the reversible seat belt tensioners. To this end, the airbag control unit J234 evaluates the signals which the ABS control unit places on the

data bus. Depending on the situation, the ABS control unit J104 can instruct the hazard warning flashers1) to be activated.

Emergency braking During an emergency braking maneouvre, the reversible seat belt tensioners are tensioned. To this end, the airbag control unit J234 evaluates the signals which the ABS control unit places on the data

bus. Depending on the situation, the ABS control unit J104 can instruct the hazard warning flashers1) to be activated. A distinction is made between the following two criteria for emergency braking.

• An emergency braking situation exists if the ABS control unit J104 detects that brake pressure had reached a specific value within a defined period of time. If the conditions for emergency braking are met, the reversible seat belt tensioners arefully tensionedby Audi pre sense basic.

• An emergency braking situation occurs if the above-mentioned conditions are not met but the ABS control unit J104 has detected an emergency braking manoeuvre based on the pedal change rate (the time it takes to switch from the accelerator pedal to the brake pedal). If the conditions for emergency braking are met, the reversible seat belt tensioners are fully tensionedby Audi pre sense basic.

System characteristics of the longitudinal dynamics • If the ESC system (Electronic Stability Control) is set to "offroad" with the TCS/ESP button J256 in quattro models, Audi pre sense basic is stillfullyavailable. In this case, the seat belt tensioners in front-wheel-drive models arenot partially tensioned. • If ESP (Electronic Stabilisation Program) is set to "Sport" or "Off" with the TCS/ESP button E256 or if Audi drive select is set to "dynamic", the seat belt tensioners arenot partially tensioned. • As regards the longitudinal dynamics, the vehicle must not be moving in reverse when the reversible seat belt tensioners deploy.

Transverse dynamics function If the vehicle oversteers or understeers, ESC will try to stabilise the vehicle. If the vehicle becomes unstable because certain physical limits have been exceeded, the airbag control unit J234partially tensionsof the electrically reversible seat belt tensioners. If the

vehicle can cannot be stabilised, the electrically reversible seat belt tensioners are fully tensioned . At the same time, the side windows and the panoramic glass sunroof2) begin to close.

System characteristics of the transverse dynamics • If the ESC system is set to "offroad" in quattro models, Audi pre sense basic is stillfullyavailable. In this case, the seat belt tensioners in front-wheel-drive models arenot partially tensioned. • If ESC is set to "off" or if Audi drive select is set to "dynamic", the seat belt tensioners arenot partially tensioned .

• If ESC in front-wheel-drive models is set to "offroad", the seat belt tensioners are fully tensionedonly if the vehicle has become very unstable and the driver is braking actively.

• If ESC in front-wheel-drive models is set to "offroad", the seat belt tensioners are fully tensionedonly if the vehicle has become very unstable and the driver is braking actively.

Crash function in the low speed range If the airbag control unit J234 detects a head-on collision with a low a rate of vehicle deceleration (no airbag deployment), it decides whether or not to fully tensionthe seat belts based on a

Audi pre-sense front In models equipped with Audi pre sense front, the following action can be taken: • Pre-charging of the brake system • Adaptation of hydraulic brake assist • Audible and visual early warnings • Acute warning by brake jolt • Automatic braking1) up to emergency braking intensity1)

• Target braking1) • Partial or full tensioning of the electrically reversible front seat belt tensioners • Closing of the panoramic glass sunroof2) and the side windows

General overview Audi pre sense front uses a "mid-range" radar sensor, which is also responsible for ACC (Audi adaptive cruise control). The radar sensor is able to detect objects up to a distance of 170 m ahead of the vehicle with an aperture angle of up to 8°. At close range, it is able to detect objects with a maximum aperture angle of 90° up to 40 m ahead of the vehicle. For this purpose, the vehicle is equipped with a radar sensor including control unit. The radar sensor and the control unit have been combined to form the

ACC unit. The ACC unit can only be replaced as a whole. If the vehicle has ACC, it is also equipped with Audi pre sense front. If the vehicle is equipped with Audi pre sense front "without" ACC, the ACC unit in fitted but it does not have ACC capability. Audi pre sense front reacts only to vehicles which are travelling in the same direction and to vehicles which have stopped, or to persons crossing the road.

The ACC unit is fitted at the centre of the front bumper. The ACC unit consists of the radar sensor and the accompanying control unit - the ACC control unit J428. The radar sensor utilises different types of radar beam depending on the speed at which the vehicle is travelling. At high speeds, the radar beam is long and narrow. This 1) 2)

allows objects further in the distance to be identified more easily, e.g. when driving on the motorway. At low speeds, the radar beam is short and wide. This allows objects further adjacent to the vehicle to be identified more easily, e.g. when driving in city traffic.

Function The radar sensors continuously scan the area ahead of the vehicle. Audi pre sense front is active even if the ACC system is not installed or is not active. The ACC control unit J428 evaluates and conditions the signals it receives and thereby determines the distance to vehicles ahead and persons crossing the road within the detection range of the radar sensor. The information supplied by the ABS control unit J104 tells vehicle how fast it is travelling. The ACC control unit J428 utilises this information to compute the speeds of vehicles ahead and persons crossing the road. The

following information is therefore available to Audi pre sense front1): • • • • • •

Speed of own vehicle Distance to vehicles ahead Speed of vehicles ahead Rate of acceleration and/or deceleration of vehicles ahead Distance to persons crossing the road Speed of persons crossing the road

Information processing The ACC control unit J428 evaluates the information and places corresponding signals on the data bus. Other bus users receive the

signals and are able to take appropriate action.

Functions of Audi pre sense front Audi pre sense front has the following functions: A

Response to vehicles: In the event of an impending collision, the driver is warned and assistance is provided by automatic braking2) up to automatic emergency braking intensity2) or by boosting2) the braking pressure applied by the driver thereby giving the driver more time to react and reducing the speed of the vehicle.

B

Response to pedestrians: In the event of an impending collision with persons crossing the road, the driver is warned and assistance is provided by automatic braking2) up to automatic emergency braking intensity2) or by boosting2) the braking pressure applied by the driver thereby giving the driver more time to react and reducing the speed of the vehicle.

Function A: response to vehicles Early warning phase If the vehicle comes within a critical distance to a vehicle ahead or a vehicle which has stopped or is stationary, the instrument cluster can pre-warn the driver both audibly and visually within defined limits. Depending on the situation, the early warning can be given across the full speed range. The system can alert the driver both to the vehicles ahead and to stationary vehicles when travelling at higher speeds.

Audi pre sense

These warnings are given within a certain time frame ahead of the last braking opportunity for braking or collision avoidance before the actual collision occurs. The timing of warnings depends on the driver's activity level. The system determines whether the driver is active or inactive based on the use of the steering wheel, foot controls and indicators. foot controls and turn signals. If the driver is classed as "attentive", warnings are issued later than for a driver classed as "inattentive". At the same time, the ABS control unit J104 pre-charges the brake system and modifies the deployment algorithms for hydraulic brake assist. This means that hydraulic brake assist starts to build up brake pressure even at low brake pedal actuation rates.

Contents

Acute warning phase If driver does not respond to the warnings, however, the ABS control unit J104 generates an acute warning by initiating a brake jolt. The warning jolt is a very brief but easily noticeable braking impulse which does not slow the vehicle down. It alerts the driver to the traffic situation and indicates to the driver that he must react immediately in order to prevent an impending collision.

Depending on how attentive the driver is determined to be, the warning jolt is produced within a certain time window ahead of the last opportunity to brake or take evasive action to avoid a collision.

Automatic brake intervention phase If the driver fails to respond to the warning jolt or only takes his foot off the accelerator, the ABS control unit J104 initiates automatic braking1). Depending on the speed at which the vehicle is travelling, braking may increase progressively to maximum le vel (emergency braking). If the vehicle automatically comes to a halt without driver input, further audible signals will sound. These

signals alert the driver to the fact that he must actively take control of the vehicle (e.g. by applying the brakes). If the driver fails to take control of the vehicle, e.g. in a model with automatic transmission, the system will release the brake and the vehicle will start to move.

Assistive brake intervention phase When the driver applies the brakes, a target braking maneouvre1) can be performed in all of the phases described above (pre-charging of the brake system, reconfiguration of hydraulic brake assist, driver warning, warning jolt, partial braking). During the target

braking manoeuvre, Audi pre sense front computes whether the driver is applying sufficient braking to be able to avoid a collision. If this is not the case, the required amount of braking is increased (up to maximum level depending on the situation).

Function B: response to pedestrians Early warning phase If the vehicle approaches a pedestrian crossing the road in such a way that a critical driving situation occurs, the driver is, where possible, provided with audible and visual early warnings via the instrument cluster. These warnings are given within a certain time window ahead of the last braking opportunity for braking or collision avoidance before the actual collision occurs. The timing of

the warning depends on the driver's activity level. The system determines whether the driver is active or inactive based on the use of the steering wheel, foot controls and indicators. foot controls and turn signals. If the driver is classed as "attentive", warnings are issued later than for a driver classed as "inattentive".

Automatic brake intervention phase When the early warning is issued, the ABS control unit J104 precharges the brake system and reconfigures the deployment algorithms for hydraulic brake assist. The ABS control unit J104 subsequently initiates automatic braking1) . Depending on the speed at which the vehicle is travelling, braking may increase progressively to maximum level. If the vehicle automatically comes to a halt

without driver input, further audible signals will sound. These signals alert the driver to the fact that he must actively take control of the vehicle (e.g. by applying the brakes).

Further functions of Audi pre sense f ront If the vehicle is equipped with both Audi pre sense front and Audi pre sense basic, the following additional action can be taken during automatic braking in response to other vehicles or persons: • Closing of the side windows • Closing of the panoramic glass sunroof2) • Tensioning of the electrically reversible seat belt tensioners

Driver prioritisation over system If the driver takes clear evasive action, accelerates or brakes during the individual phases of the Audi pre sense front functions, the

momentary actions of Audi pre sense front (e.g. automatic braking1)) are suppressed or cancelled.

Effect of system settings on Audi pre sense front functions • If Audi pre sense is deactivated in the MMI, the functions of Audi pre sense front a re deactivated, too. • When the ESC system (Electronic Stability Control) is set to "offroad" with the TCS/ESP button J256 in quattro models, Audi pre sense front is still available. In this case, Audi pre sense front is not available in front-wheel-drive models. • If ESC (Electronic Stability Control) is switched off with the TCS/ ESP button, certain functions of Audi pre sense front are not available or only available to a limited extent.

Note:Audi pre sense front is not available or only available to a limited extent until: • ESP is reactivated with the TCS/ESP button E256. • ESC is reactivated by turning the ignition off and on again. • ESC is activated automatically by activating ACC. A precondition is that the vehicle is equipped with ACC.

System characteristics of Audi pre sense front • If an automatic braking manoeuvre1) is initiated by the vehicle, Audi pre sense front can help to situatively reduce the speed of the vehicle by up to 40 kph.

• Depending on the situation, the ABS control unit J104 can instruct the hazard warning flashers (emergency braking warning) 1) to be activated. • Certain functions of Audi pre sense are deactivated when reversing.

Front camera for driver assistance systems R242 The front camera for driver assistance systems R242 assists Audi pre sense. On the basis of information provided by the front camera, for instance, braking power can be increased through partial braking operation II if the radar sensor and the front camera have detected a critical situation. The front camera can assist Audi pre sense front by performing the following actions: • By initiating a warning jolt in response to stationary vehicles. • By increasing braking power through partial braking operation II.

Front camera for driver assistance systems R242 A second-generation BOSCH front camera is used for the first time on the Audi Q2. This camera will be rolled out as product upgrade

for the Audi A3 (type 8V) The new camera has a resolution of 1280 x 960 pixels.

654_024

The front camera for driver assistance systems R242 is used with the following driver assistance systems: • Audi active lane assist (AALA) • Camera based traffic sign recognition • Basic version of main beam assist – The basic version of main beam assist can also use the camera of main beam assist control unit J844. However, if a front camera R242 is installed

• adaptive cruise control (ACC) – The front camera for driver assistance systems R242 is not a compulsory requirement when ordering ACC. If the camera is installed, however, then ACC uses it. • Traffic jam assist

in the vehicle, the function runs in this camera.

• assist • Emergency Audi pre sense front – The system uses front camera R242 if it is installed, but also functions without the front camera.

Audi active lane assist (AALA) Audi active lane assist will be available as an option for the Audi Q2. This is a function known from other models. The software of the AALA runs in the front camera for driver assistance systems R242, which is also responsible for lane recognition. The customer can choose between the two steering points ("early" and "late") under "Audi active lane assist" in the MMI menu "Driver

assistance systems". In the "early" setting, the system continuously provides corrective steering inputs with the aim of keeping the vehicle in the centre of the lane. In the "late" setting, corrective steering inputs do not start until the vehicle approaches the lane boundary line. This way, it helps the driver stay in lane.

New driver take-over prompt features of Audi active lane assist A new form of driver take-over prompt by AALA is used in the Audi Q2. A prompt to take over the steering is issued when the system assumes that the driver has taken both hands off the steering wheel while AALA is active. The driver is not allowed to drive without his hands on the stee ring wheel while Audi active lane assist is active. This is monitored by evaluating the signals from the steering torque sensor. If AALA assumes that the driver does

In models launched prior to the Audi Q2, the driver take-over prompt is implemented as a simple brake jolt. In these models, the status of AALA switches from "active" to "inactive" shortly after the text message „Lane assist: please take over steering“ is displayed. No further corrective steering inputs are performed. In this case, the system no longer issues a vibration warning. The colour of the AALA function lamp in the instrument cluster changes from

Further notes on sequence diagram 1 The x-axis of the diagram serves as a timeline showing the chronological order to the various actions of the driver and Audi active lane assist. The time mark 0 is the point at which the text message prompting the driver to take over is displayed because the system assumes that the driver does not have his hands on the steering wheel. The times shown on the x-axis are guide values given to provide a better understanding of the chronological sequence. They may deviate from the actual values. This also applies to sequence diagrams 2 to 4. In the time up to marking -10s the driver is driving with his hands on the steering wheel. Audi lane assist is active, i.e. the vehicle is travelling faster than 60 kph. ACC is switched off. The driver takes his hands off the steering wheel at the -10 s mark. The signal from the steering torque sensor tells the system that the driver no longer has his hands on the steering wheel. At the 0 s mark the text message "Lane Assist: please take over steering“ is displayed in the instrument cluster.

saying that this changeover is only made if the system was set previously to "late". If this is not the case, the "early" setting continues to apply. The "early" setting helps keep the vehicle in the centre of the lane in which it is travelling. At the 12 s mark the AALA system determines that the driver still does not have his hands on the steering wheel and issues a further warning tone. If this situation remains unchanged at the 16 s mark, a warning tone is issued and a n additional brake jolt is initiated. If the AALA system determines that the driver still does not have his hands on the steering wheel at the 20 s mark, Audi active lane assist deactivates itself. However, the text message remains displayed in the instrument cluster.

The described response after the 20 s mark applies only if the vehicle meets the following two conditions: 1.) It does not have emergency assist.

A warning tone issued at the 2 s mark alerts the driver once again to the situation and to the text message. At the 7 s mark the AALA system determines that the driver still does not have his hands on the steering wheel and changes the timing of the corrective steering input to "early" It goes without

or 2.) It has emergency assist but the ACC assist system is currently deactivated or is unavailable due to a fault.

Note The new emergency assist system will be described later in this self study programme.

Sequence diagram 2 – Driver takes over the steering during the driver take-over prompt sequence Sequence diagram 2 also shows a driving scenario in which AALA is active and ACC is switched off. The driver subsequently takes his hands off the steering wheel and AALA commences the driver take-over prompt sequence. This time, unlike in sequence diagram 1, the driver takes over steering the vehicle again during the driver take-over prompt sequence. For this reason, AALA is not deactivated.

Normal vehicle operation with AALA

Another difference is the customer's setting with regard to the timing of corrective steering inputs. Given that this has been set to "early" by the customer, there is no need for an automatic changeover to "early" at the 7 s mark.

Emergency assist Function The task of the emergency assist system is to bring the vehicle to a controlled stop in its current lane in an emergency. It is activated if the driver takes his hands off the steering wheel when Audi active lane assist or traffic jam assist is active and does not respond to the prompt to take over the steering. During the standstill braking operation the system continues to prompt the driver to take over the steering. In this critical situation AALA als o warms the other traffic in the immediate vicinity by activating the hazard warning flashers. To reduce the risk of colliding with a vehicle ahead, ACC is also activated when emergency assist is activated. For this purpose, ACC must be switched on and activatable. Technical requirements for the implementation of emergency assist in the Audi Q2 are, therefore, Audi active lane assist and ACC. Emergency assist is only available in combination with an automatic gearbox at launch of the new Audi Q2. The software of emergency assist is integrated in the front camera for driver assistance systems R242.

Emergency assist is designed for situations in which the driver is unable to continue driving due to an acute health problem. Emergency assist can bring the vehicle to a stop automatically and without the vehicle leaving the lane in which it is travelling. The Audi Q2 is the first Audi model in which emergency assist is offered. Emergency assist was first featured in a VW Group model in 2014, when the VW Passat was launched. The Volkswagen and Audi systems are based on the same software, but differ slightly in several respects. Emergency assist can only activate itself at speeds of greater than 60 kph only when AALA is active and at speeds of less than 60 kph if traffic jam assist is active.

Note Emergency assist can only deploy once per "terminal 15" cycle.

Sequence diagram 3 – Activation of emergency assist while Audi active lane assist is active Up to the point at which emergency assist initiates standstill braking, sequence diagram 3 is identical to sequence diagram 1, which shows a complete driver take-over prompt sequence. However, there is one exception: in sequence diagram 1 ACC was

switched off throughout, while in sequence diagram 3 ACC was active throughout. In sequence diagram 3, this difference accounts for that fact that emergency assist is activated at the end of the driver take-over prompt sequence.

Further notes on sequence diagram 3 The driver take-over prompt sequence of the AALA system ends at the 20 s time mark and emergency assist is activated. The following action is taken: 1.) The text message "Emergency assist: carrying out automatic

emergency stop“ is displayed. 2.) A further warning tone is issued. 3.) The vehicle commences standstill braking. During the standstill braking operation the vehicle is braked to a 2 stop at a rate of approx. 1.8 m/s . However, this value may be exceeded briefly by the ACC when approaching a vehicle ahead if this is necessary for automatic cruise control. At the 24 s time mark a warning tone is issued and a brake jolt is initiated. At the 26 s time mark the speed of the vehicle drops below the 80 kph threshold. Consequently, a much stronger emergency brake

jolt is applied when the next "scheduled" brake jolt is initiated at the 28 s time mark. The hazard warning flashers are activated at the same time as the emergency brake jolt in order to alert vehicles in the vicinity to this emergency situation. Now a further warning tone and a brake jolt are initiated cyclically every 4 seconds. If the vehicle finally comes to a stop at the 47 s time mark, the electrical parking brake is closed. The ACC abd AALA systems are deactivated. The hazard warning flashers stay switched on. The audible warning and the text message in the instrument cluster remain active until the driver takes over the steering.

Criteria for cancelation of driver take-over prompt in the Audi Q2 Criteria for cancelation of emergency assist in the Audi Q2 The driver take-over prompt sequence ends when any of the following events takes place:

Active emergency assist ends when any of the following events takes place:

1.) The system detects that the driver has taken over steering the vehicle again.

1.) The system detects that the driver has taken over steering the vehicle again.

2.) Audi active lane assist is switched on and off using the button on the turn signal stalk.

2.) The driver presses the brake or accelerator pedal.

3.) Audi active lane assist enters "inactive" state because the condition for activation no longer applies. This can occur, for example, due to the following events: • • • •

The vehicle's speed drops below 60 kph. No lane boundary lines are detected by the system. The lane is either too narrow or too wide. The radius of a curve is too small.

3.) Audi active lane assist is switched on and off using the button on the turn signal stalk. 4.) ACC is switched off via the ACC steering column stalk. 5.) A turn signal is activated. 6.) TCS is executing corrective inputs. 7.) A vehicle door is opened.

Emergency assist is not activated if the driver take-over prompt is ended prematurely.

8.) The electrical parking brake is applied.
