ACC: Sensor and control unit

The ACC sensor is integrated in the ACC control unit. The ACC sensor is a radar sensor, which is capable of both long-range detection (up to 200 meters) and  short-range detection (up to 60 meters) in front of the vehicle.

The ACC sensor detects the distance, angle and speed of moving objects. The relevant data is processed in the ICM control unit or the LDM control unit.
