When repositioning the threaded spindle relative to the housing in the direction of the spindle axis, the energy absorbing installation is configured to absorb kinetic energy.

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.

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.

Abstract: A method for producing a steel component from a flat steel sheet is provided. The produced steel component includes a substrate and a coating.
