Abstract
A backing system for a trailer and vehicle and associated method includes recording an image of a hitch for the vehicle and trailer assembly with a camera. A plurality of distances related to geometry of the vehicle and the trailer and a plurality of reference points are learned based on the camera inputs. A plurality of reference distances related to the plurality of reference points are then determined. A current hitch angle may then be determined using the plurality of reference distances and the geometry distances.
