  • Patent number: 11124235
    Abstract: A trailer backup assist system for motor vehicles includes an auxiliary user input feature that can be used by a vehicle operator to provide a steering curvature command corresponding to a desired vehicle path curvature without requiring a user to move a steering wheel of the motor vehicle. The trailer backup assist system is configured to control a vehicle speed while the vehicle is backing up with a trailer attached thereto utilizing an input comprising at least one of a steering curvature command and an angle of a trailer relative to the vehicle. The trailer backup assist system controls at least one of a brake system, an engine torque, and a transmission gear selection to thereby control vehicle speed in a reverse direction.

  • Patent number: 9610943
    Abstract: A system for parallel parking a vehicle in a target parking space is provided herein. A sensing system is configured to detect objects located proximate the target parking space. A park assist system is communicatively coupled to the sensing system. The park assist system is configured to automatically steer the vehicle during a backing maneuver into the target parking space while limiting the speed of the vehicle based on a steering wheel angle. The sensing system is also configured to automatically steer the vehicle during maneuvers inside the target parking space while limiting the speed of the vehicle based on a relative position of at least one of a rear bounding object and a front bounding object.
