摘要： A vehicle system comprises a hitch ball mounted on a vehicle. The system further comprises a plurality of sensor devices comprising an ultrasonic sensor and an image sensor. A controller is configured to process image data from the image sensor identifying a coupler position of a trailer. The controller is further configured to process ultrasonic data from the ultrasonic sensor identifying a proximity of the trailer. Based on the proximity of the trailer, the system is configured to identify the trailer in a detection range of the image sensor.

摘要： A hitch assist system for a vehicle comprises an imaging system that receives image data of a hitch ball and trailer coupler, and a controller. The controller estimates a distance between a point on each of the hitch ball and trailer coupler. The points are parallel to a plane defined by a surface beneath the hitch ball and trailer coupler. The controller tracks the distance with a pixel-domain comparison between each of the points responsive to the distance being less than a first threshold, and maneuvers, via steering and braking systems, the vehicle along a path such that the distance is indicative of the points being coaxial.

摘要： A system for assisting in aligning a vehicle for hitching with a trailer includes a steering system that adjusts a steering angle of the vehicle, a braking system that adjusts a speed of the vehicle, an imaging system that receives image data of a trailer disposed in an area proximate the vehicle, and a controller. The controller detects, within a threshold distance defined from a stationary point on the vehicle and the trailer, a position of a coupler from the image data, and, responsive to the position being less than the threshold distance, a status of the trailer based on the image data being indicative of a position of a hitch ball relative to the coupler within a second threshold. The controller maneuvers, via the steering and braking systems, the vehicle based on the status.
