发明名称 Implement hitch and control system
摘要 A hitch for coupling an implement to a utility vehicle includes adjustable length coupling elements and a pivotal coupling unit coupled thereto. A control system automatically controls the length of the coupling elements to control the direction of the line of action of the draft forces, the position of the towing point defined by the coupling unit, and the orientation of the Implement relative to the utility vehicle. The control system includes sensors for sensing the position of the implement relative to the vehicle, for determining a set of reference positions, and for sensing forces applied to the coupling elements. The control system also automatically controls the length of the coupling elements as a function of the sensor signals.
