Method for operating power-assisted steering device for vehicle, involves determining deflection of steering device and adjusting return force depending on deflection direction

摘要

The method involves determining (204) a deflection of a steering device, where deflection indicates whether the steering device is deflected to right or left from a central position. A return force is adjusted (208) depending on a deflection direction. A restoring force characteristic is selected (206) when the steering device is deflected to right, where another restoring force characteristic is selected (205) when the steering device is deflected to left. The deflection amount is determined (202), by which the steering device is deflected from central position in the deflection direction. An independent claim is included for a power-assisted steering device for a vehicle.
