Abstract
A method for controlling a steer-by-wire steering system for a motor vehicle may involve determining a torque request signal with a position controller of an activation unit based at least on a desired steering angle and an actual steering angle, limiting the torque request signal in a signal limiting device of the activation unit such that the torque requested by the limited torque request signal is limited to a permissible torque range, and transmitting the limited torque request signal to an electronically controllable steering actuator. The signal limiting device may determine a reference torque signal by way of a reference controller based at least on the desired steering angle and the actual steering angle. The signal limiting device may define the permissible torque range by way of a selectable maximum deviation from the reference torque signal.
