Abstract

A steering system for a motor vehicle, which allows steer-by-wire operation, a hand-torque actuator being connected in the steer-by-wire mode to a steering handle, e.g. a steering wheel, to simulate a steering resistance or a restoring torque. In order to be able to ensure adequate operating safety for the vehicle if the hand-torque actuator fails, even if the steering system is operated on a steer-by-wire basis, damping means are provided, which damp adjusting movements of the steering handle by the driver in the steer-by-wire mode if the hand-torque actuator fails.
