Self Study Program 970343 – The 2015 Audi A3 Vehicle Electronics and Driver Assistance Systems PDF. Today, Audi is already setting new standards for driver assistance systems in the A3 – introducing technologies from the luxury class into the premium compact segment. Several optional systems and one standard solution are offered in the new 2015 Audi.

The optional Audi side assist supports the driver in changing lanes. From a vehicle speed of 18 mph (30 km/h ), radar sensors at the rear monitor what is happening behind and to the sides of the A3. A yellow LED in the door mirror housing lights if another vehicle is driving in the blind spot or is rapidly approaching from the rear. If the driver still activates the turn signal for a lane change, the indicator turns bright and flashes at a high frequency – a very effective warning signal.

Audi active lane assist becomes active at a speed of 40 mph (65 km/h). It detects lane markings on the roadway based on images from a small video camera mounted on the rear-view mirror. If the vehicle approaches a lane marking without activating the turn signal, the system assists the driver in steering back into the lane by making a slight intervention in the electromechanical power steering system.
Of the optional driver assistance systems in the new A3, adaptive cruise control (ACC) is the most complex. This radar-based system maintains the desired distance to the vehicle ahead by autonomously accelerating and braking within certain limits over speeds ranging from 18 – 93 mph (30 to 150 km/h). The driver can set the distance and the control dynamics over four levels. If the car has the assistance package, which combines several systems, the control range is extended to 125 mph (200 km/h).

In the North American region vehicles, the system intervenes just before crossing over a detected lane marking. This function can help to prevent the car from leaving the driving lane unintentionally, for example, due to driver inattentiveness.

This new generation of lane-keeping assistance can offer continuous relief to the driver, enhancing driving comfort.
