Abstract

An engine-driven vehicle/implement coupling system includes a mechanical coupling and one or more electronic and/or hydraulic connections. A coupling condition monitoring system includes one or two electronic control units, sensors for sensing a coupling condition of the electronic and/or hydraulic connection, and a sensor on the mechanical coupling for generating a signal representing a coupling condition of the mechanical coupling. Sensor signals are transmitted to the electronic control unit which, in response prevents erroneous coupling or uncoupling and prevents drive-away of the vehicle or implement.
