Abstract
An overlay steering system for a vehicle includes a mechanical steering apparatus for the transfer of a steering torsional moment at a predetermined transfer ratio to at least one steered wheel, a wheel angle sensor connected to at least one steered wheel for generating a wheel angle signal corresponding to an angle of the at least one steered wheel, a comparison device for comparing the steering angle signal and the wheel angle signal as well as for generating a comparison signal based on the steering angle and the wheel angle, and an electromechanical converter for generating the overlay torsional moment, if the comparison signal indicates the presence of a deviation from the predetermined relation between the steering angle and the wheel angle of the at least one steered wheel, resulting in a reduction of the deviation.
