1. A trailer backup assist system, comprising:
- a sensor measuring a hitch angle between a vehicle and a trailer;
a steering input device providing a desired backing path of the trailer; and
a controller generating a steering command for the vehicle based on the desired backing path and the hitch angle and generating a countermeasure for operating the vehicle when the steering input device fails to operate.

Abstract
A trailer backup assist system includes a sensor that senses a hitch angle between a vehicle and a trailer. The trailer backup assist system also includes a steering input device that provides a backing path of the trailer. Further, the trailer backup assist system includes a controller that generates a steering command for the vehicle based on the hitch angle and the backing path. The controller generates a countermeasure for operating the vehicle when the steering input device fails to provide the desired backing path fails or the controller otherwise fails to sense the input signal from the steering input device.

8. An input failure mitigation system for a vehicle reversing a trailer, comprising:
-
a steering input module providing a desired backing path of the trailer; and a controller detecting failure of the steering input module to provide the desired backing path, engaging a countermeasure when the steering input module fails to operate, and disengaging the countermeasure upon a driver intervention to operate the vehicle. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
