Abstract

Method for operating a steering system for a motor vehicle with at least one steerable wheel, a servo drive and a superimposed gear mechanism, the steering movement, initiated by the driver of the vehicle, and the movement for producing the steering movement of the steerable wheel, initiated by the servo drive for realizing useful functions (VSR, LAFN) being superimposed by the superimposed gear mechanism into a pinion angle, the servo drive for initiating the movement being triggered by a control signal (δMd) of a control device. The servo drive is turned back in a controlled manner when a substitute mode of at least one useful function (VSR, LAFN) of the steering system is switched off or on.
