Adaptive Cruise Control (ACC)
Safety and ease of use
Speed is often underestimated and the distance to the vehicle in front is easily overestimated. The ACC system is able to automatically adjust the driving speed, as well as the distance to the vehicle ahead, in line with the preset settings.
It can be used at speeds of 25 km/h or faster. Its main field of application, however, is in driving on main roads and motorways.
The ACC radar sensor with a range of approx. 150 m recognises the distance to and the relative speed of the vehicles ahead in the same lane. The ACC control unit calculates the best approach strategy from the sensor data, the course of the lane, the speed of its own vehicle and the actions of the driver, and triggers the engine torque and brake management system (retarder and service brake) accordingly. The speed, acceleration and retardation of the vehicle are actively regulated and the distance to the vehicle ahead is maintained.
