Abstract
A method can be used to adapt a steering torque for controlling a feedback actuator of a steer-by-wire motor vehicle steering system. The method may involve providing a basic steering torque, providing a rack-force-based steering torque, determining a difference between the basic steering torque and the rack-force-based steering torque, and if the difference exceeds a predetermined limit value adapting the basic steering torque to the rack-force-based steering torque and transmitting a resulting steering torque to control the feedback actuator. However, if the difference remains below the predetermined limit value, then the method may involve transmitting the basic steering torque to control the feedback actuator.
