1. A method for tracking a trailer end in an image using a controller comprising:
receiving an image from at least one camera;
identifying a trailer end in the image and tracking a motion of the trailer end through the image for a period of time using a controller;
generating a motion model based on the motion of the trailer end through the image using the controller; and
responding to the trailer end exiting the image by maintaining motion of the trailer end per the motion model for a delay time period and establishing an estimated trailer end position dictated by the motion model at the end of the delay time period in response to the time period elapsing and the trailer end not being visible using the controller.
