  • Patent number: 11919568
    Abstract: A system and strategy for reducing rapid steering wheel movement at the end of an autopark maneuver. The strategy includes maintaining or ramping-out power-steering motor torque to reduce steering wheel movement that may occur due to tire windup that has occurred up to that point in the autopark maneuver. The strategy may include the stopping of an autopark maneuver at any time during the maneuver, or functioning at the end of an autopark maneuver. The autopark event may be a park-out maneuver.

  • Patent number: 10377234
    Abstract: Methods and systems are disclosed for activating a vehicle ignition system. An example vehicle includes an ignition system, a plurality of sensors, and a processor. The processor a processor is configured to determine, based on data received from the sensors, (i) that a person occupies a driver's seat of the vehicle, (ii) that a key fob corresponding to the vehicle is present, and (iii) that an input has been received at a shifter of the vehicle. The processor is also configured to responsively activate the ignition system.

  • Patent number: 10377409
    Abstract: A manual steering torque input is measured. A manual steering mode of a vehicle is actuated when the manual steering torque input is below a first torque threshold and above a second torque threshold for longer than a time threshold that is based on a vehicle speed.

  • Patent number: 10279803
    Abstract: A backup assist system for a vehicle reversing a trailer includes a brake module and a throttle module. The system further includes a controller having a vehicle speed detector and coupled with the brake module and the throttle module for implementing a backup mode including detecting an adverse operating condition and then adjusting at least one of the brake module and the throttle module and terminating the backup mode upon detecting the adverse operating condition for a time interval.

  • Publication number: 20190092380
    Abstract: A system includes a computer that is programmed to determine a vehicle steering wheel angle based on a vehicle steering torque and a vehicle pinion angle and to determine a compensated steering torque by applying a high-pass filter to the determined vehicle steering wheel angle. The computer is programmed to actuate a vehicle component based on the determined compensated steering torque. A parameter of the high-pass filter is based on a vehicle speed.

  • Patent number: 10127459
    Abstract: A trailer type identification system is provided herein. The system includes an imaging device for capturing images of a trailer connected to a vehicle, and a controller for analyzing the captured. The controller identifies vehicle and trailer contours, predicts a trailer type based on detection of a connection between the identified vehicle and trailer contours, and validates the prediction if the identified trailer contour exhibits motion during a vehicle turn event.

  • Patent number: 9975573
    Abstract: An operation mode of a first actuator engaged with a steering rack is determined. An operation mode of a second actuator engaged with a steering column is determined. The operation mode of one of the first and second actuators is adjusted upon detecting a failure in the other of the first and second actuators. At least one of the steering rack and the steering column is actuated based on the operation mode. In an angle control mode, a predetermined steering angle is provided to the first and second actuators to adjust the steering rack according to the steering angle. In a torque control mode, a steering column torque from a torsion sensor disposed on the steering column is provided to the first and second actuators to adjust the steering rack according to the steering column torque.
