ABSTRACT:
A control device for controlling the transmission ratio of an infinitely variable transmission of a motor vehicle is disclosed. The transmission ratio is adjustably dependent on the position of a hydraulic control valve which is movable in dependence upon the difference between a predetermined desired engine speed and the actual engine speed. A stop member displaceable in dependence upon the transmission ratio regulates the minimum possible engine speed in dependence thereon.
