Abstract
A control system for coupling two final control elements as regards the actuated position and the actuating force, in which each final control element is assigned a separate force-control loop, these loops being coupled to one another by way of the actual-force values prevailing at the final control elements, is to be improved as regards its versatility for different applications. According to the invention, this is achieved by virtue of the fact that the two force-control loops are coupled by a proportionality factor, thus giving a force transmission ratio between the final control elements. The control system according to the invention can be used with particular advantage in a steer-by-wire steering system of a motor vehicle, in which case one final control element is formed by a steering handle and the other final control element is formed by steered vehicle wheels.
