Steering angle sensor

The steering angle sensor picks up the angle of rotation at the steering wheel. The steering angles determined by the sliding contacts (2 voltage values) comprise a full steering wheel turn. After 360° steering wheel turn, the voltage values are repeated. This means that the steering angle sensor also counts the steering wheel turns. The total steering angle is thus formed from the currently measured steering angle and the number of steering wheel turns.

The steering angle sensor is connected via the chassis and suspension CAN (F-CAN) with the DSC control unit as well as the DSC sensor.
