Abstract
A method may be utilized to control 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's request for a steering angle can be applied by a driver via steering input means and which outputs a feedback signal to the steering input means as a reaction to the driver's request and a driving condition of the motor vehicle, and a signal transmission that transmits the driver's request to the control unit. The control unit controls the steering actuator to convert the driver's request into deflection of the steered wheels. The method may involve determining wheel slip of a front wheel, performing frequency analysis of a profile over time of a wheel slip signal of the front wheel, and determining the feedback signal based on the result of the frequency analysis.
