Abstract
A steering system for a motor vehicle with a steering drive train having at least one steerable wheel, one actuator and one auxiliary drive. The steering wheel is operable by the driver of the vehicle as well as by mechanically configured offset devices. The offset devices have rotating input and output shafts and a predetermined offset angle between the input shaft and the output shaft. The auxiliary drive superimposes the steering motion initiated by the steering wheel and the motion initiated by the actuator to generate the steering motion of the steerable wheel. A control signal dependent on the angular offset and the rotational motion of the input shaft is computed. The actuator is then controlled dependent on at least the generated control signal to initiate the actuator initiated motion. Any structurally unavoidable nonuniformity of rotational motion is compensated for by the superimposition of an appropriate added angle.
