Abstract
A disclosed method of maneuvering a vehicle-trailer unit in reverse travel with a backing system includes, among other things, determining that the vehicle-trailer unit is backing up with an electronic control unit for the backing system. A current hitch angle is determined, which represents the relative angle between the vehicle and the trailer with the electronic control unit. A requested hitch angle rate of change versus distance traveled is calculated with the electronic control unit, wherein the requested hitch angle rate of change is based upon a input from a joystick control which provides a requested hitch angle rate of change signal value in proportion to the joystick position. A steering angle is calculated with the electronic control unit based upon the requested hitch angle rate of change, wherein the steering angle will allow movement of the vehicle-trailer unit in the reverse direction to obtain the requested hitch angle rate of change; and a request is sent to a steering system to provide the steering angle.
