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 sensor fails to sense the hitch angle.
Claims20
A trailer backup assist system, comprising:
- a sensor sensing a hitch angle between a vehicle and a trailer;
- a steering input device providing a backing path of the trailer;
- and
- a controller generating a steering command for the vehicle based on the hitch angle and the backing path, wherein the controller generates a countermeasure for operating the vehicle when the sensor fails to sense the hitch angle.
A sensor failure mitigation system for a trailer backup assist system, comprising:
- a sensor measuring a hitch angle between a vehicle and a trailer;
- and
- a controller detecting failure of the sensor to measure the hitch angle, engaging a countermeasure when the sensor fails, and disengaging the countermeasure upon a driver intervention to operate the vehicle.
A method for mitigating sensor failure of a trailer backup assist system, comprising;
- sensing a hitch angle between a vehicle and a trailer;
- generating a steering command for the vehicle based on the hitch angle;
- generating a countermeasure command for the vehicle when the hitch angle fails to be sensed;
- and
- disengaging the countermeasure command upon a driver intervention.
