A7 Sportback Driver assistance
Navigation based vehicle assistance
Wouldn't it make sense if your car knew the road you were driving on and adjusted its setup accordingly?
Imagine if the suspension could improve the aerodynamics of the car by lowering itself when on a motorway or ensure the gearbox was in the correct gear for a corner so it didn't have to change down mid-bend. Maybe it could even switch on the corner lights to better illuminate a crossroads. Well the A7 Sportback can.
Welcome to the New Audi A7 Sportback's Navigation based vehicle assistant.
Audi lane assist with steering torque added, keeps an eye on the road to ensure that the Audi A7 Sportback remains in lane.
If the lane assist system detects that the A7 Sportback is moving out of lane, it intervenes to correct the movement. This can prevent unintentional lane changes through lack of concentration or through falling asleep at the wheel.
The system works by using a video camera to scan road markings when the car is going between 60 and 250 km/h.
The lane assist intervenes in two ways. There is an early steering intervention which continuously maintains that position of the car in the centre of lane, and a late steering intervention which intervenes to correctively steer the A7 Sportback back into lane.
The steering intervention is suppressed during intentional lane-changing without use of indicator.
The function is available even if a lane boundary marking is only detected on one side.
The head up display is key information relevant to the driving situation projected onto the bottom of the windscreen directly in the driver's field of view - ensuring that information is passed from the head up display to the driver without diverting attention away from the road.
The system displays an array of information including:
Road speed including variations due to weather conditions (eg. "when wet")
Cruise control set speed
Navigation information
Audi lane assist information
Warnings
Infotainment lists
Road sign displays
The system is controlled through the MMI, and can be turned on and off.
Camera based recognition of speed limit signs Displayed in the DIS.
Registers additional signs such as wet conditions.
Benefits - If sign is missed by the driver this information can be conveniently read in the DIS.

With the optional Night Vision assistant, an integral thermal imaging camera, discretely mounted in the front grill, significantly improves safety and comfort when driving at night. Helping driver's spot hazards beyond the view illuminated by the headlight beam the thermal camera registers heat sources that are located near, or approaching, the route ahead.
Located in the Driver's Information System, between the speedometer and rev counter a camera's eye view of the road ahead is displayed to the driver. The system will highlight people using their heat source. Typically a person standing by the side of the road would be highlighted in yellow, indicating they are outside of the vehicles route, however should the person start to walk towards the road the advanced image processing system will identify that they could walk into the car's path and will highlight them in red.
The system can be adjusted through the MMI menu and allows adjustment of highlighting people, the warning system and the contrast of the screen.
The optional parking assistance system aids the driver when parallel and perpendicular parking.
When parallel parking the system detects a space at a speed of up to 30km/h or at 15km/h when parking in a perpendicularly. Once a space is detected, the system then operates the steering wheel while the driver operates the speed via the accelerator.
NB. It is important to remember that the driver remains responsible for the manoeuvre at all times.
The Audi A7 Sportback comes as standard with the Audi Parking System Plus which includes front and rear parking sensors and a visual indicator on the MMI screen.
