Abstract: A method for backing up a trailer hitched to a vehicle includes mounting a rear backup camera at a vehicle and hitching a trailer at the hitch of the vehicle. Responsive to processing captured image data by a processor of the control, at least a portion of the trailer tongue of the trailer is detected using an edge detection algorithm. Responsive to processing at the control of image data captured by the rear backup camera during a backing up maneuver of the trailer hitched to the vehicle, trailer angle of the trailer relative to a longitudinal axis of the vehicle is determined. The control, based at least in part on trailer angle of the trailer, controls a steering system of the vehicle during the backing up maneuver of the trailer hitched to the vehicle to back up the trailer hitched to the vehicle along a rearward trajectory.
