Abstract:
A power steering system for a vehicle is described, wherein a magnetic or electromagnetic actuator, which can be acted on via a controller, is associated with a torsion bar connected to a steering wheel, and by which the torsional stiffness of the system is variable in dependence on the vehicle speed, the steering angle speed and/or the transverse acceleration. In this connection, the electrical power supply of the magnetic or electromagnetic actuator taking place via the controller is interrupted or reduced when a steering angle speed of zero is detected or when a steering angle speed of zero and a vehicle speed of zero are detected.
