Abstract
A hitch control system controls a hitch for coupling an implement to a utility vehicle. The hitch includes longitudinally adjustable coupling elements operable to shift or pivot the implement in a lateral direction relative to the utility vehicle. A sensor, such as a wheel steering angle sensor, senses a parameter associated with lateral or turning movements of the vehicle. A control unit automatically adjusts the length of the coupling elements as a function of the sensor signals so that the position of the implement relative to the vehicle is adapted to the curved path. This reduces the outer radius of the area over which the vehicle and implement travel when traveling along a curved path and helps avoid collisions with objects.
