Steering-angle sensor
The steering-angle sensor supplies information about the slip angle of the front wheels to the PSM control module (intention of driver in relation to direction of travel). In the PSM control module this signal is used to calculate the required vehicle behaviour with respect to its transverse dynamics by means of the calculation of the vehicle speed. The sensor has its own microcontroller. The information is transmitted to the PSM control module by means of a CAN bus. Without the information from the steering-angle sensor, the PSM control module cannot produce a picture of the desired direction of travel. If the steering angle sensor is replaced, a calibration must be performed.
