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 an input which provides a requested hitch angle rate of change signal value. 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.
