  • Patent number: 11634136
    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. An electronic control unit (ECU) includes an image processor operable to process image data captured by the camera. The ECU, via image processing of image data captured by the camera, detects a trailer rearward of the vehicle and determines a first path of travel for the vehicle to follow to maneuver the vehicle toward the trailer and to align the tow ball of the vehicle with a trailer hitch of the trailer. The ECU generates an output to maneuver the vehicle along the determined first path of travel. Responsive to detection of an object entering the first path of travel, the ECU determines a second path of travel for the vehicle to follow that avoids the detected object entering the determined path of travel.

  • Patent number: 11508156
    Abstract: A vision system for a vehicle includes a camera and an electronic control unit (ECU) with an image processor. The ECU generates a reduced resolution frame of captured image data and the ECU determines a reduced resolution detection result based on pedestrian detection using the reduced resolution frame of captured image data. The ECU, responsive to processing by the image processor of image data, generates a cropped frame of captured image data and the ECU determines a cropped detection result based on pedestrian detection using the cropped frame of captured image data. Responsive to determining the reduced resolution detection result and determining the cropped detection result, the ECU merges the reduced resolution detection result and the cropped detection result into a final pedestrian detection result. The final pedestrian detection result is indicative of presence of a pedestrian within the field of view of the camera.

  • Patent number: 11014561
    Abstract: A trailer hitching 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. A control includes an image processor operable to process image data captured by the camera. The image processor, via image processing of image data captured by the camera, detects a trailer and trailer hitch rearward of the vehicle and determines a first path of travel for the vehicle to follow so as to maneuver the vehicle so as to have its tow ball aligned with the trailer hitch. The control maneuvers the vehicle along the determined first path of travel. Responsive to detection of an object entering the first path of travel, the control determines a second path of travel and maneuvers the vehicle along the second path of travel to avoid the detected object entering the determined path of travel.

  • Publication number: 20160180158
    Abstract: A vision system of a vehicle includes a camera configured to be disposed at a vehicle so as to have a field of view exterior of the vehicle. An image processor is operable to process image data captured by the camera. The image processor, responsive to image processing of captured image data when the camera is disposed at the vehicle, is operable to determine the presence of a pedestrian in the field of view of the camera. The vision system may utilize a linear classifier to identify areas where a pedestrian is more likely to be present for enhanced processing of those areas. The vision system may utilize a Histogram Intersection Kernel classifier for enhanced processing of identified areas. The vision system may utilize detection area filtering to reduce processing of image data representative of areas of the field of view where a pedestrian is not likely to be present.
