Abstract
A method for operating a steering mechanism () of a motor vehicle, wherein a steering rod () can be held or displaced along its longitudinal axis (a) by an electric motor () so that the wheel steering angle () of at least one wheel () on at least one vehicle axle () can be maintained or changed. When a force (F) acts essentially axially on the steering rod (), displacement of the steering rod () is at least inhibited by a detent torque (RM) of the electric motor () and/or by a self-induced torque (M) of the electric motor. The invention also relates to a device for carrying out the method and to a steering mechanism, which is preferably in the form of a steer-by-wire steering system. A control unit is provided for carrying out the method.
