More Information
Summary:A power steering system including a sensor arranged or located in the steering system. The sensor detects an acoustic vibration or an acceleration signal in the steering system during a change in the steering angle and generates a sensor signal representing the vibration or the acceleration signal. A control unit receives the sensor signal and compares the sensor signal with a threshold value to detect a fault state; for example when the sensor signal is larger than the threshold value.
