Abstract
A vehicle is provided that includes a trailer hitch, a camera oriented to capture images of the trailer hitch, and a controller processing the captured images, detecting a trailer safety chain associated with a trailer, determining a connection state of the trailer safety chain to the vehicle, and generating an output indicative of the determined connection state of the trailer safety chain to the vehicle. The vehicle may determine a change in a scene of the captured image following placement of a trailer coupler onto a vehicle hitch and determine a trailer connection state based on the change in scene.
