Abstract: A trailer angle detection system for a vehicle towing a trailer includes a camera disposed at a rear portion of the vehicle and having a field of view rearward of the vehicle. The camera includes a two dimensional imager array having multiple rows and columns of photosensing elements. An image processor processes image data captured by the camera. With the vehicle towing a trailer, and via processing by the image processor of image data captured by the camera, the trailer angle detection system detects a portion of the trailer that is being towed by the vehicle. The trailer angle detection system determines, via processing by the image processor of image data captured by the camera, an angle of the trailer relative to the vehicle responsive to determination of which columns of photosensing elements sense the detected portion of the trailer in the field of view of the camera.

Abstract: A trailer angle detection system for a vehicle towing a trailer includes a rearward viewing camera disposed at a rear portion of a vehicle, and an image processor operable to process image data captured by the camera. Responsive to processing of captured image data when the vehicle is towing a trailer, the trailer angle detection system determines the presence of the trailer at the rear of the vehicle and attached at the vehicle and determines feature vectors of the detected trailer over multiple frames of captured image data. Responsive to movement of the trailer relative to the vehicle, the trailer angle detection system tracks feature vectors for different positions of the detected trailer. The trailer angle detection system determines an angle of the trailer responsive to detection of tracking of feature vectors the trailer in the field of view of the camera over multiple frames of captured image data.

Abstract: A trailer backup assist system of a vehicle includes a camera disposed at a vehicle and having a field of view exterior and rearward of the vehicle. An image processor is operable to process image data captured by the camera. With a trailer connected at the rear of the vehicle, the image processor is operable to determine an angle of the trailer relative to the longitudinal axis of the vehicle. A user input is operable by a user to select a general direction or zone of travel of the trailer during a reversing maneuver of the vehicle. Responsive to the determined trailer angle and the selected zone of travel, the trailer backup assist system is operable to control the steering of the vehicle to drive the vehicle and trailer rearward such that the trailer travels generally towards a region encompassed by the selected direction or zone of travel.

Abstract: A vehicular vision system includes a rearward-viewing camera disposed at a vehicle and viewing at least rearward of the vehicle. The rearward-viewing camera connects with a control via a cable. The cable carries control data from the control to the rearward-viewing camera and carries image data captured by the rearward-viewing camera from the rearward-viewing camera to the control. The control generates an output provided to a video display device of the vehicle. The video display device includes a video display screen viewable by a driver of the vehicle. During a reversing maneuver of the vehicle, the video display screen displays video images of an area rearward the vehicle derived from image data captured by the rearward-viewing camera and carried to the control by the cable. Image data captured by the rearward-viewing camera is processed at an image processor to detect an object present rearward of the vehicle.

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 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. Image data is captured via the camera and provided to the ECU. An image processor of the ECU processes captured image data. A condition is determined via processing at the image processor of the ECU captured image data. The condition comprises a shadow present in the field of view of the camera within ten frames of captured image data or a damaged condition of the imager within two minutes of operation of the camera. The condition is indicative of a condition where processing of captured image data degrades in performance. The ECU determines a safe state for the vehicle responsive to determining the condition.

Abstract: A vehicular vision system includes a rearward viewing camera and a control, which includes a processor that processes image data captured by the camera. During a reversing maneuver of the vehicle, the control, via processing of captured image data, detects points of interest of detected objects. Responsive to detection of the points of interest of the detected objects, the control determines if the detected objects have height dimensions and determines that objects having a height dimension greater than a threshold height are objects of interest. During the reversing maneuver of the vehicle, the control determines distances to the determined objects of interest and determines which object of interest is closest to the vehicle. During the reversing maneuver of the vehicle, responsive to the determination of the closest object of interest rearward of the vehicle, the control determines whether the determined closest object of interest is a potential hazard.

Abstract: 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.

Abstract: A method of detecting a trailer angle of a trailer being towed by a vehicle includes capturing frames of image data via a camera of the vehicle while the vehicle is towing a trailer, and, via processing by an image processor of frames of captured image data while the vehicle is towing the trailer, determining presence of the trailer being towed by the vehicle, and determining feature vectors of the trailer being towed by the vehicle. The feature vectors of the trailer are determined by determining features that have similar angular changes between a current frame of captured image data and a previous frame of captured image data. The angle of the trailer relative to the vehicle is determined responsive to tracking of determined feature vectors of the trailer present in the field of view of the camera over multiple frames of captured image data.
