Abstract
A method for generating a return torque signal in an electric servo steering system of a vehicle, including the steps of: determining a current steering wheel position; determining a current vehicle speed; generating a return torque signal as a function of the steering wheel position and the vehicle speed; determining a current directional relationship between a torque exerted on the steering wheel and a speed of steering wheel rotation; determining a scaling factor dependent on the directional relationship; and multiplying the return torque signal by the scaling factor in order to obtain a modified return torque signal. Also, a servo steering system which is designed to carry out such a method.
