Abstract
A steering system for a work vehicle towing a towed implement is described. A steering control unit is coupled to a location signal generation arrangement on the vehicle, a steering actuator, a memory for storing desired path data of the implement and a slope sensor for detecting a lateral inclination of the work vehicle or the implement. The steering control unit calculates a lateral offset compensation value to steer the work vehicle such that the implement is moved on the desired path and a slope offset compensation value based upon a signal from the tilt sensor to compensate for slope forces pulling the implement down a lateral slope. A steering signal is sent to the steering actuator based upon the lateral offset compensation value and the slope offset compensation value.
