Abstract
A method of controlling a backing system for a vehicle and trailer assembly includes: initiating a backing system mode; recording at least one image of a trailer for the vehicle and trailer assembly with a camera mounted to the vehicle; identifying a current plurality of features of the trailer in the image; learning a current plurality of distances associated with the current plurality of features. Then comparing the current plurality of features and distances with stored plurality of features of distances to determine if there is a match. If there is not a match a current calibration of a plurality of relative distances associated with the plurality of reference features is learned while the driver performs a number of preset calibration maneuvers. A relative position between the vehicle and the trailer is determined using the stored calibration and the current plurality of features and current plurality of relative distance.
