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.

Abstract: A leader location-determining receiver determines a leader location of a lead vehicle. A follower location-determining receiver determines a follower location of a follower vehicle, which has a container for storing a material. A data processor or position module calculates an observed relative position between the lead vehicle and the follower vehicle. Target relative positions are established between the lead vehicle and the follower vehicle. A data processor or selector selects a preferential one of the established target positions. A data processor or adjuster adjusts the observed relative position of the follower vehicle to achieve the selected preferential one of the established target positions.
