Applies to vehicles: with Audi adaptive cruise control
The adaptive cruise control is a combined speed and distance control system. It assists the driver by controlling the road speed and the distance to the vehicle in front within certain limits imposed by the system. The adaptive cruise control system can accelerate and brake when it detects a vehicle in front. This provides maximum comfort on long motorway journeys, for instance.
The braking guard can warn you of impending collisions and can initiate the application of the brakes Link.
What can the adaptive cruise control do?
The adaptive cruise control uses a radar sensor Fig. 2 which is integrated in the front of the vehicle and is subject to certain system limitations Link. Stationary objects are disregarded.
When there is no traffic in front, the adaptive cruise control works just like a normal cruise control system by maintaining a constant speed. When you draw closer to a vehicle in front, the adaptive cruise control matches your speed to that vehicle by automatically applying the brakes, and then maintains a constant distance (which you can adjust in the settings). As soon as it detects no more vehicles in front, the adaptive cruise control accelerates back up to the cruising speed.
