Abstract: A vehicular vision system includes a camera module mounted at an in-cabin side of a windshield of a vehicle and an electronic control unit (ECU) comprising electronic circuitry and associated software. The ECU, responsive to processing of location data captured by a global positioning system, determines a current geographical location of the vehicle. The ECU, with the vehicle approaching an intersection of another road, and at least in part via processing at the ECU of image data captured by the camera, determines a right-of-way order of other vehicles at the intersection based on (i) the current geographical location of the vehicle and (ii) an order of arrival of the other vehicles at the intersection relative to arrival of the equipped vehicle at the intersection. Based on the determined right-of-way order of the other vehicles at the intersection, the ECU determines when the vehicle has the right-of-way at the intersection.

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.

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 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.

Abstract: A vehicular trailer assist system includes a rearward viewing camera disposed at a vehicle that views a trailer hitched at a fifth wheel hitch at a bed of the vehicle. With the trailer hitched to the fifth wheel hitch at the bed of the vehicle, the vehicular trailer assist system, via processing fisheye-view frames of image data captured by the camera, 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 a region of interest (ROI) in a transformed bird's-eye view frames of image data that includes a region where the fifth wheel hitch is present. The vehicular trailer assist system, via a Hough transform that transforms the determined ROI from a Cartesian coordinate system to a polar coordinate system, determines a trailer 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. 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. During a turning portion of the calibration maneuver, a subset of frames of image data is stored, each stored frame of image data including the trailer at a different trailer angle relative to a longitudinal axis of the vehicle. The control, responsive to storing the subset of frames of image data, converts each stored frame of image data to an edge image and matches each edge image to the determined initial trailer template, and determines a location of a hitch ball of the vehicle.

Abstract: A method for calibrating a vehicular camera of a vehicular vision system includes placing a target with a first portion having a first geometric pattern and a second portion having a second geometric pattern within the field of view of the vehicular camera, and capturing image data with the camera representative of the field of view of the vehicular camera. Two edges of both portions of the target are detected, and edge pixels of the detected edges are determined. First and second vanishing points of the target in the captured image data are determined based on the determined edge pixels of the respective first and second portions of the target. Camera orientation is determined based on location of the determined first vanishing point relative to location of the determined second vanishing point. The vehicular camera is calibrated based on the determined camera orientation.

Abstract: A vehicular parking assistance system includes a camera disposed at a vehicle and capturing image data. An electronic control unit (ECU) includes an image processor for processing image data captured by the camera. The parking assistance system, responsive to an input, determines a direction of travel for an automated parking maneuver. The parking assistance system, responsive to processing by the image processor of image data captured by the camera, determines a boundary of a free space in the direction of travel for the automated parking maneuver. The free space at least partially bounds an area where the vehicle can maneuver without colliding with a detected object. The parking assistance system, while driving the vehicle in the direction of travel, laterally adjusts a path of the vehicle based on the determined boundary of free space to avoid the detected object.

Abstract: A vehicular trailer hitching assist system includes a camera disposed at a rear portion of a vehicle and viewing at least rearward of the vehicle. During a reversing maneuver of the vehicle toward a trailer that is spaced from the vehicle at a distance from the vehicle, the camera views at least a portion of a front profile of the trailer. An electronic control unit (ECU) includes an image processor operable to process image data captured by the camera. The vehicular trailer hitching assist system, via image processing at the ECU of image data captured by the camera during the reversing maneuver of the vehicle toward the trailer, determines a plurality of landmarks corresponding to the front profile of the trailer. Based at least in part on the determined plurality of landmarks, the vehicular trailer hitching assist system determines location of a trailer coupler of the trailer.
