Publication number: 20230290155Abstract: A method for determining a safe state for a vehicle includes disposing a camera at a vehicle and disposing an electronic control unit (ECU) at the vehicle. Frames of image data are captured by the camera and provided to the ECU. An image processor of the ECU processes frames of image data captured by the camera. A condition is determined via processing at the image processor of the ECU frames of image data captured by the camera. The condition includes a shadow present in the field of view of the camera within ten frames of image data captured by the camera or a damaged condition of the imager within two minutes of operation of the camera. The ECU determines a safe state for the vehicle responsive to determining the condition.Type: ApplicationFiled: May 22, 2023Publication date: September 14, 2023Inventors: Horst D. Diessner, Richard C. Bozich, Aleksandar Stefanovic, Anant Kumar Lall, Nikhil Gupta

Patent number: 11634136Abstract: 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.Type: GrantFiled: May 24, 2021Date of Patent: April 25, 2023Assignee: MAGNA ELECTRONICS INC.Inventors: Nikhil Gupta, Horst D. Diessner, Richard Bozich, Jyothi P. Gali, Aleksandar Stefanovic, Hilda Faraji, Miad Moarref, Xai Phan, Galina Okouneva, Brijendra Kumar Bharti

Patent number: 11014561Abstract: 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.Type: GrantFiled: February 1, 2018Date of Patent: May 25, 2021Assignee: MAGNA ELECTRONICS INC.Inventors: Nikhil Gupta, Horst D.

Patent number: 10936884Abstract: A vision system for a vehicle includes a camera configured to be disposed at a vehicle so as to have a field of view exterior of the vehicle. A processor is operable to process image data captured by the camera. The vision system determines conditions where processing of captured image data degrades in performance due to environmental conditions. The vision system, responsive to a determined condition, determines a safe state for image processing of captured image data for that determined condition. A failsafe algorithm, responsive to processing of image data captured by the camera and responsive to the determined condition, and in accordance with the determined safe state for that determined condition, determines true negatives and avoids false positives and false negatives.Type: GrantFiled: January 22, 2018Date of Patent: March 2, 2021Assignee: MAGNA ELECTRONICS INC.Inventors: Horst D.

Patent number: 9296337Abstract: A method of calibrating a vehicular camera installed in a vehicle, with the camera having an imager and a camera microcontroller, includes searching for and/or determining a reference point in the images and adjusting the position of an overlay applied to displayed images depending on the reference point. The method may include comparing the determined reference point's actual position to its expected position and determining an offset amount with which to shift the overlay on the images displayed at an in-vehicle display responsive to the determined offset amount, and adjusting the position of the overlay applied to the images displayed at the in-vehicle display responsive to the determined offset amount.Type: GrantFiled: October 5, 2015Date of Patent: March 29, 2016Assignee: MAGNA ELECTRONICS INC.Inventors: Marko Vico, Sharon Zibman, Aleksandar Stefanovic
