Abstract
A system for trailer coupler localization for guidance during a hitching maneuver for a vehicle includes a trailer device including a trailer coupler and a graphic providing structure affixed to the trailer coupler. The structure includes at least one predefined graphic image. The system further includes a rear facing camera device attached to the vehicle and providing a captured image of the predefined graphic image. The system further includes a computerized controller, including programming to receive and analyze the captured image of the predefined graphic image to determine a relative position of the graphic providing structure to the camera device. The controller further includes programming to utilize the analysis to determine a relative position of the trailer coupler to a trailer hitch ball of the vehicle and to provide an output to control the hitching maneuver based upon the relative position.
