Abstract
A steering system of a non-tracked motor vehicle whose steered vehicle wheels are connected in the normal operation with respect to the effect with a steering handle only by way of an electronic automatic control unit which continuously monitors itself with respect to a correct operation. As a function of a desired-value generator, which is operated by the steering handle, and an actual-value generator operated by the vehicle wheels, this automatic control system operates an adjusting drive for the steering adjustment of the steered vehicle wheels. In the event of a malfunctioning of the automatic control system, a forced coupling is automatically switched effective between the steering handle and the steered vehicle wheels. When the forced coupling is switched on, the steering system operates as much as possible in the manner of a conventional power steering system. In that event, the forces and torques transmitted between the steering handle and the steered vehicle wheels by way of the forced coupling are determined while utilizing the occurring elastic distortion of the forced coupling.
