  • Trailer backup assist system having advanced user mode with selectable hitch angle limits
    Patent number: 10814912
    Abstract: A backup assist system for a vehicle reversing a trailer includes a controller receiving a driver control signal and outputting a vehicle backing steering command based on the control signal and limited by one of a first angle limit corresponding with a calculated maximum controllable angle and a second angle limit at a maneuverability threshold below the maximum controllable angle. The system further includes an interface outputting an indication of the one of the first and second angle limits.

  • Adaptive steering control for robustness to errors in estimated or user-supplied trailer parameters
    Patent number: 10730553
    Abstract: A system for assisting in reversing of a vehicle-trailer combination includes a vehicle steering system and a controller. The controller outputs a steering signal to the steering system to maintain the vehicle-trailer combination along a straight backing path and determines a straight-backing offset of a hitch angle in the vehicle-trailer combination as a proportion of an integral of a measured characteristic of the vehicle-trailer combination that varies from a desired zero value.

  • Adaptive steering control for robustness to errors in estimated or user-supplied trailer parameters
    Patent number: 10604184
    Abstract: A system for assisting in reversing of a vehicle-trailer combination includes a vehicle steering system and a controller. The controller outputs a steering signal based on a control parameter to the steering system to maintain the trailer along a commanded backing path, determines an error between a measured behavior of a characteristic of the vehicle-trailer combination and a predicted behavior of the characteristic, and adjusts the control parameter based on the error.
