Technologies and techniques for determining a gear rack force of a steer-by-wire steering system that includes a steering handle, for specifying a steering angle as a function of a steering handle position. A vehicle wheel actuator is configured to set the steering angle by movement of a gear rack of the steering system, by applying an actuating force, the gear rack being coupled to at least one vehicle wheel. A reaction force actuator may produce a reaction force on the steering handle in accordance with a gear rack force. Friction operation is determined, in which gear rack movement does not occur when the steering handle position is changed, and, if friction operation is present, the gear rack force is determined on the basis of the actuating force of the vehicle wheel actuator.
