Abstract: A vehicular trailer assist system includes a camera disposed at a vehicle and viewing at least a portion of a trailer hitched to the vehicle. With the trailer hitched to the vehicle and while the vehicle is operating in a calibration state and being driven straight, the system determines edges of the trailer. With the trailer hitched to the vehicle and after the vehicle is driven straight and while the vehicle is operating in the calibration state and being driven along a curved path, and at least in part via processing of captured frames of image data, the system determines a hitch point of the trailer hitched to the vehicle. With the vehicle not operating in the calibration state, and based in part on the determined hitch point of the trailer hitched to the vehicle, the system determines a jack-knife angle of the trailer relative to the vehicle.

Abstract: A vehicular trailer assist system includes a camera disposed at a vehicle and viewing at least a portion of a trailer hitched to the vehicle. The system, during a first turning maneuver of a calibration maneuver of the vehicle and trailer, stores a subset of the frames of image data captured by the camera. Each stored frame of the stored subset of the frames captures the trailer at a respective different trailer angle relative to a longitudinal axis of the vehicle. The system determines image data edges for each stored frame of image data. The system, after performing the first turning maneuver of the calibration maneuver and during a second turning maneuver of the calibration maneuver, and based at least in part on the determined image data edges for the stored frames of image data, determines a jack-knife angle of the trailer relative to the longitudinal axis of the vehicle.

IPC: B60R1/00
Abstract: A vehicular trailer assist system includes a rearward viewing camera viewing a trailer hitched at a fifth wheel hitch at a bed of the vehicle. With the trailer hitched to the vehicle, the vehicular trailer assist system transforms fisheye-view frames of image data captured by the rearward viewing camera into bird's-eye view frames of image data. The vehicular trailer assist system determines the fifth wheel hitch within a transformed bird's-eye view frame of image data. The vehicular trailer assist system warps the transformed bird's-eye view frame of image data, which includes (i) an X-axis that indicates change in a trailer angle of the trailer relative to the vehicle and (ii) a Y-axis that indicates distance from the fifth wheel hitch. The vehicular trailer assist system, using the X-axis of the warped transformed bird's-eye view frame of image data, determines the trailer angle of the trailer relative to the vehicle.

Abstract: A vehicular trailer assist system includes a camera disposed at a rear portion of a vehicle and having an exterior field of view that includes at least a portion of a trailer hitched to the vehicle. A control, responsive to processing of frames of image data captured by the camera and during a calibration maneuver by the vehicle, determines a trailer template of trailer hitched to the vehicle. The control, during a turning portion of the calibration maneuver, determines a trailer collision angle based on the determined trailer template. The control, after completion of the calibration maneuver, determines a current trailer angle of the trailer relative to the vehicle as the vehicle is driven along a road. The control alerts an operator of the vehicle if the current trailer angle is within a threshold amount of the determined trailer collision angle.

Abstract: A vehicular trailer assist system includes a camera at a vehicle and viewing at least a portion of a trailer hitched to the vehicle. A control, responsive to processing of frames of image data captured by the camera and during a calibration maneuver by the vehicle, determines an initial trailer template of trailer hitched to the vehicle. The control, during a turning portion of the calibration maneuver, and at least in part via processing of frames of image data captured by the camera, determines a hitch ball location of a hitch of the vehicle based on the determined initial trailer template. The control, after completion of the calibration maneuver, determines a current trailer angle of the trailer relative to the vehicle via processing of frames of image data captured by the camera and based on the determined hitch ball location as the vehicle is driven along a road.
