HITCHING MANEUVER
First Claim
1. A computer, comprising a processor and a memory, the memory storing instructions executable by the processor to:
- upon initiation of a trailer-hitching procedure, obtain image data of an area that is in a horizontal plane with respect to a vehicle and behind the vehicle, the area including a trailer hitch mounted to, and extending rearwardly from, the vehicle, wherein a vehicle hitch ball is mounted to the vehicle hitch;
locate the hitch ball in the image data;
define, within the area, an overshoot zone having a length extending from a vehicle rear bumper to a nearest point on the vehicle hitch ball and having a width that is a sum of a diameter of the hitch and two times a lateral offset;
define, within the area, a misaligned zone that has a border extending a misaligned zone length from the vehicle rear bumper to a line tangent to a rearmost point of the hitch ball; and
cause a vehicle action upon determining that a trailer coupling is detected in the overshoot zone or the misaligned zone, the action including at least one of updating a display, actuating a vehicle actuator to stop the vehicle, and actuating a vehicle actuator to restart a hitching maneuver.

Abstract
Upon initiation of trailer-hitching, an image is obtained of an area behind and in a horizontal plane with respect to a vehicle, the area including a rearwardly extending trailer hitch, with a hitch ball mounted thereto, mounted to the vehicle. The hitch ball is located in the image. An overshoot zone, having a length extending from a vehicle rear bumper to a nearest point on the vehicle hitch ball and having a width that is a sum of a diameter of the hitch and two times a lateral offset, is defined within the area, as is a misaligned zone having a border extending from the vehicle rear bumper to a line tangent to a rearmost point of the hitch ball. A vehicle action is caused upon determining that the trailer coupling is detected in the overshoot zone or the misaligned zone.
