Abstract: A vehicular trailer angle detection system includes a camera disposed at a rear portion of a vehicle. The system determines, via processing of frames of image data captured by the camera, features of a trailer present rearward of the vehicle and hitched to the vehicle by determining features that have similar position changes between a current frame of image data captured by the camera and a previous frame of image data captured by the camera. Responsive to movement of the trailer relative to the vehicle, and via processing of captured frames of image data, the system tracks determined features over multiple captured frames of image data for different positions of the trailer relative to the vehicle. The system determines angle of the trailer relative to the vehicle based at least in part on tracking of determined features of the trailer over multiple captured frames of image data.

Abstract: A vehicular trailer assist system includes a camera disposed at a rear portion of a vehicle and viewing a portion of a trailer hitched at a hitch of the vehicle. During a reversing maneuver of the vehicle and hitched trailer, the vehicular trailer assist system, responsive to processing at an electronic control unit (ECU) of image data captured by the camera, determines a trailer angle of the trailer relative to a longitudinal axis of the vehicle. Based at least in part on the determined trailer angle, the vehicular trailer assist system determines a trailer direction of movement of the trailer while the vehicle is reversing with the trailer hitched at the hitch of the vehicle. The vehicular trailer assist system determines a virtual destination location rearward of the trailer and in the determined trailer direction and controls steering of the vehicle to reverse the trailer towards the virtual destination location.

Abstract: A vehicular trailer guidance system includes an electronic control unit (ECU), a rear backup camera and a trailer camera disposed at a rear portion of a trailer hitched to the vehicle. A display screen is disposed in the vehicle and viewable by a driver of the vehicle. With the trailer hitched to the vehicle, the display screen is operable to display video images derived from image data captured by the trailer camera. At least in part via processing at the ECU of image data captured by the trailer camera, an instruction that aids maneuvering the vehicle in reverse with the trailer hitched thereto during a reversing maneuver of the vehicle and trailer is generated. During the reversing maneuver of the vehicle and trailer, the display screen displays an alert when angling of the trailer relative to the vehicle approaches a jackknife condition.

Abstract: A vehicular trailer hitching assist system includes a rearward-viewing camera disposed at a vehicle and viewing a hitch of the vehicle and a trailer coupler of a trailer that is positioned rearward of the vehicle and not coupled to the hitch of the vehicle. The vehicular trailer hitching assist system, via image processing of image data captured by the rearward-viewing camera, determines height of the trailer coupler relative to the hitch of the vehicle. The vehicular trailer hitching assist system, responsive to the determined height of the trailer coupler relative to the hitch of the vehicle being greater than a threshold amount, generates a signal to adjust the height of the trailer coupler.

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.

Abstract: A vehicular backup assist system includes an ultrasonic sensor disposed at a trailer hitch that is configured to be attached at a rear portion of the vehicle. A control includes a processor for processing sensor data captured by the ultrasonic sensor. The control, with the trailer hitch attached at the vehicle, and during a reversing maneuver of the vehicle, and responsive to processing of sensor data captured by the ultrasonic sensor, detects presence of an object rearward of the vehicle and in the vicinity of the trailer hitch. Responsive to detecting presence of the object, the control alerts a driver of the vehicle of the detection.

Abstract: A trailering assist system for a vehicle includes a camera disposed at a rear portion of a vehicle and having a field of view rearward of the vehicle, the field of view encompassing at least a portion of a trailer rearward of the vehicle. The camera captures image data, which is representative of at least a front profile of the trailer, which includes a trailer coupler of the trailer. An ECU includes an image processor that processes image data captured by the camera. The ECU, responsive to image processing of captured image data, determines a location of the front profile of the trailer relative to the vehicle. Responsive to determining the location of the front profile, the ECU determines a plurality of outline landmarks that represent a shape of the front profile of the trailer. Based on the determined outline landmarks, the ECU determines a location of the trailer coupler.
