<p>A steering system for a work vehicle (10) towing a towed implement (12) is described. A steering control unit (46) is coupled to a location signal generation arrangement (50, 52) on the vehicle (10), a steering actuator (36), a memory for storing desired path data of the implement (12) and a slope sensor (64) for detecting a lateral inclination of the work vehicle (10) or the implement (12). The steering control unit (46) calculates a lateral offset compensation value to steer the work vehicle (10) such that the implement (12) is moved on the desired path and a slope offset compensation value based upon a signal from the tilt sensor (64) to compensate for slope forces pulling the implement (12) down a lateral slope. A steering signal is sent to the steering actuator (36) based upon the lateral offset compensation value and the slope offset compensation value.</p> |
