Abstract
A control system controls a work vehicle towing a towed implement. The control system includes a steering angle sensor, an implement position generating unit generating an actual implement position signal, a desired implement position generating unit generating a desired implement position signal, a vehicle position generating unit generating an actual vehicle position signal, a processor unit generating an implement angle signal as a function of the actual implement position signal and the actual vehicle position signal, and a control processor generating the steering control signal as a function of the actual implement position signal, the actual vehicle position signal, the implement angle signal, the steering angle signal and the desired implement position signal. A vehicle steering actuator steering vehicle steerable wheels in response to the control signal.
