Claim 0:
1. A method for controlling a steer-by-wire steering system for a motor vehicle that includes an electronically controllable steering actuator that acts on steered wheels, a control unit, a feedback actuator to which a driver request for a steering angle can be applied by a driver via a steering input means and which outputs a feedback signal to the steering input means as a reaction to the driver request and to a driving condition of the motor vehicle, and a signal transmission that transmits the driver request to the control unit, wherein the control unit controls the electronically controllable steering actuator to convert the driver request into a deflection of the steered wheels, the method comprising:
determining a wheel slip of a front wheel of the steered wheels;
performing frequency analysis of a profile over time of a wheel slip signal of the front wheel, wherein performing the frequency analysis comprises classifying dominant frequencies via predefined frequency values, and allocating a predefined feedback signal to the dominant frequencies based on the classification; and
determining the feedback signal based on a result of the frequency analysis.
