More Information
Summary:A system for assisting in aligning a vehicle for hitching with a trailer includes a steering system that adjusts a vehicle steering angle, a braking system that adjusts a vehicle speed, an imaging system that receives image data of a drawbar assembly being receivable in a hitch receiver, and a controller. The controller is configured to detect an edge of the drawbar assembly from the image data, target an endpoint at a fixed offset from the edge and a stationary point on the vehicle, and maneuver, via the steering and braking systems, the vehicle along a path to align the endpoint with the trailer.
