Abstract: A trailer angle detection system for a vehicle towing a trailer includes a camera disposed at a rear portion of a vehicle so as to have a field of view exterior and rearward of the vehicle, and an image processor operable to process image data captured by the camera. Responsive to processing of a region of interest of image data captured by the camera, the trailer angle detection system determines the location of a known patterned target at the trailer being towed by the vehicle. Responsive to determination of the location of the target, the system determines a region of interest of the captured image data that encompasses the target. Responsive to processing of image data of the region of interest and determining the location of the target relative to the vehicle centerline, the trailer angle detection system calculates an angle of the trailer relative to the vehicle centerline.

Abstract: A trailer assist system for a vehicle includes a camera with a field of view encompassing a trailer hitch disposed at the vehicle. A control includes an image processor that processes image data captured by the camera that is representative of images of the trailer hitch present in the field of view of the camera. The control, responsive to processing at the control of image data captured by the camera, detects at least one feature of the trailer hitch at a Cartesian coordinate location and transforms the Cartesian coordinate location of the detected feature to a cylindrical coordinate location. The control generates a vertical segment that passes through the detected features and determines cylindrical coordinates of a ground point along the vertical segment. The control, responsive to determining the cylindrical coordinates of the ground point, determines a 3D location of the trailer hitch at the vehicle.

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 vehicular trailer assist system includes a camera disposed at a rear portion of a vehicle and having a field of view exterior of the vehicle. A control includes a processor for processing image data captured by the camera. The control, responsive to processing at the control of captured image data, determines a trailer angle of a trailer hitched to the vehicle. Responsive to determining the trailer angle, the control determines a trailer direction that is based at least in part on the determined trailer angle. The control is operable to determine a virtual destination location that is a location that is a predetermined distance from the trailer and in the determined trailer direction. Responsive to determining the trailer direction, and during a reversing maneuver of the vehicle and trailer, the control controls steering of the vehicle to direct the trailer in the determined trailer direction toward the virtual destination location.

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.
