Abstract

A steer-by-wire steering system has a steering wheel actuator and a braking device that acts on the steering column. The braking device is activated when the vehicle steering wheel is to be blocked or at least sharply braked, such as when the steering stop is reached or a wheel goes over the edge of a curb. The braking device functions like a switchable freewheel.
