Abstract
Methods for controlling a steer-by-wire steering system including a steering actuator controlled via a steering request and brings about movement of a steering rack to steer vehicle wheels. A feedback actuator transmits reactions of the road to a steering wheel via an aligning torque. A setpoint position of the steering rack is determined in a signal processing unit based on a steering wheel steering angle. The setpoint position is transmitted with an actual position of the steering rack or with a measured wheel steering angle as an actual value to a control unit which calculates a setpoint torque of an electric motor of the steering actuator. The method includes monitoring the power of the motor required to reach the determined setpoint position. When the required power exceeds the maximum power of the motor the motor is operated at maximum power torque present at the steering wheel is increased.
