1. A backup assist system for a vehicle and trailer combination, comprising:
- a vehicle steering system;
a camera generating images of the trailer; and
a controller;
processing sequential images the trailer;
selecting a baseline image;
determining a collision angle based on a location of a feature of the trailer in the baseline image; and

Abstract
A backup assist system for a vehicle and trailer combination includes a vehicle steering system, a camera generating images of the trailer, and a controller. The controller processes sequential images the trailer, selects a baseline image, and determines a collision angle based on a location of a feature of the trailer in the baseline image. The controller further controls the steering system to maintain a hitch angle below a lesser of a maximum controllable angle and the collision angle.
