ABSTRACT:
A vehicle steering system has an electronic control system for coupling a steering device and the steered wheels of the vehicle, with the steering angle setpoint signal passing though a filter before a setpoint/actual value comparison is made. The filter passes essentially only those frequencies below an adjustable transition frequency. A switch is made to a low transition frequency when there is to be a direct translation between the steering device and the steered wheels of the vehicle.
