The system also provides an input module that receives a desired curvature of the trailer. A controller of the system includes a curvature regulator determining a desired hitch angle based on the desired curvature and a steering angle of the vehicle. In addition, the controller of the system includes a hitch angle regulator generating a steering angle command based on the desired hitch angle and the measured hitch angle. In this embodiment, the controller is configured to operate the trailer backup assist system irrespective of the attached trailer having a conventional tongue or a gooseneck tongue.
