Abstract
A system for assisting in aligning a vehicle for hitching with a trailer includes a controller that receives scene data from a detection system and identifies the trailer within the area to the rear of the vehicle, derives a backing path to align a hitch ball mounted on the vehicle to a coupler of the trailer, and derives a steering control signal, a powertrain control signal, and a brake control signal to respectively control a vehicle steering system, a vehicle powertrain control system, and a vehicle brake system to maneuver the vehicle, including reversing along the backing path. The controller processes at least one of the steering control signal, powertrain control signal, and brake signal according to one of a distance to the coupler, derived from the scene data, or a vehicle speed, obtained from the vehicle speed sensor.
