  • Publication number: 20210170947
    Abstract: A vehicular trailer assist system includes a camera disposed at a rear portion of a vehicle, a plurality of sensors, and an electronic control unit (ECU) having a processor for processing image data captured by the camera and sensor data captured by the plurality of sensors. The ECU, responsive to processing of image data captured by the camera, determines a trailer angle of the trailer relative to the vehicle. The ECU, responsive to processing of sensor data captured by the plurality of sensors, predicts a yaw rate of the vehicle and a trailer angle of the trailer relative to the vehicle at a future time. The ECU, responsive to predicting the yaw rate, determines a corrected vehicle yaw rate based on processing of captured image data and captured sensor data, and determines a corrected trailer angle, and determines a vehicle heading and position and a trailer heading and position.

  • Patent number: 10994774
    Abstract: A vehicular control system includes a forward viewing camera having a field of view forward of the vehicle. A control includes an image processor operable to process image data captured by the camera to determine road curvature of a curved section of a road being traveled by the vehicle. Based on the determined road curvature, the control determines tangents to the determined road curvature along the curved section of the road. The control steers the equipped vehicle along the curved section of the road by adjusting steering of the vehicle to follow the determined tangents to the determined road curvature as the vehicle moves along the curved section of the road.

  • Publication number: 20210078634
    Abstract: A vehicular trailering assist system includes a rearward viewing camera at a vehicle and an electronic control unit (ECU). During a reversing maneuver of the vehicle and trailer while the vehicle is in motion and the trailer is hitched to the vehicle, the ECU (i) determines a target trajectory for the trailer, (ii) determines a lateral path deviation of the trailer that represents a deviation of a current trajectory of the trailer from the target trajectory for the trailer, (iii) determines a trailer heading angle correction, and (iv) determines a target trailer angle of the trailer relative to the vehicle based on the current trailer angle of the trailer and the trailer heading angle correction. Responsive to determination of the target trailer angle of the trailer, the ECU controls steering of the vehicle to achieve the target trailer angle and direct the vehicle and the trailer towards the target trajectory.

  • Publication number: 20200380268
    Abstract: A method of assisting a driver in maneuvering a vehicle with a trailer hitched to the vehicle includes equipping a vehicle with a trailering assist system that includes (i) a camera disposed at the vehicle and viewing a trailer that is hitched the vehicle and (ii) a control having an image processor. During a reversing maneuver of the vehicle and trailer, image data is captured by the camera and vehicle parameters are provided to the control. Responsive to the vehicle parameters and processing of captured image data, the trailering assist system estimates an estimated trailer angle and an estimated vehicle steering wheel angle. The estimated vehicle steering wheel angle and an actual steering wheel angle are compared to determine a steering wheel angle error. The estimated trailer angle is modified in subsequent determinations of the estimated trailer angle based at least in part on the determined steering wheel angle error.

  • Patent number: 10755110
    Abstract: A trailering assist system for a vehicle includes a camera disposed at a vehicle, with the camera having a field of view rearward of the vehicle that encompasses a trailer that is being towed by the vehicle. The camera is operable to capture image data. A control of the system includes an image processor operable to process captured image data. Responsive to input of vehicle parameters and processing of captured image data by the image processor, the trailering assist system is operable to determine an estimated trailer angle and an estimated vehicle steering wheel angle. The control compares the estimated vehicle steering wheel angle to a measured or determined or actual vehicle steering wheel angle to determine an error value. The control is operable to generate an output when the error value is at or above a threshold level.
