Abstract

The turning radius of a differentially steered vehicle towing a trailer is controlled when turning so that its turning radius is greater than a minimum allowable turning radius. The turning radius may be autonomously adjusted using a controller to monitor the instantaneous rotational speed differential between the driven wheels and increase or decrease the relative speed between the wheels when the instantaneous rotational speed differential exceeds a threshold rotational speed differential, indicating a turn which is too tight. Alternately, the turning radius may be controlled by the vehicle's operator, who receives a signal from the controller indicating that the vehicle's turning radius is less than the minimum allowable. The operator may then take action to enlarge the turning radius using manual controls.
