Abstract: A method and system are described for controlled supplemental steering, by actuating a supplemental steering element, of a trailing implement connectable via a hitch to a pulling source, and wherein the trailing implement includes a pair of parallel wheels, a controller, a position sensing system that generates a hitch position history comprising a stored set of recent positions of the hitch point, and a steering angle actuator. The method carried out by the system includes maintaining a history of positions of the hitch, determining a target steering angle for the supplemental steering element, and actuating the steering angle actuator in accordance with the target steering angle. During the maintaining the history of positions of the hitch, the history of positions of the hitch is updated by performing a rotation operation and a translation operation on a set of coordinates of the history corresponding to previous hitch positions.
