Abstract: A calibration system for calibrating a radar sensing system for a vehicle includes at least one calibrating radar transmitter spaced from a location where the vehicle may be positioned. The vehicle includes a radar sensor disposed at the vehicle so as to sense exterior of the vehicle. The radar sensor includes a plurality of transmitters that transmit radio signals and a plurality of receivers that receive radio signals that are transmitted radio signals reflected from an object. A processor is operable to process an output of the receivers. With the vehicle positioned at the location, the at least one calibrating transmitter transmits signals that are received by the receivers of the radar sensor. Responsive to processing by the processor of the output of the receivers when receiving signals transmitted by the at least one calibrating transmitter, the calibration system determines if the radar sensor is misaligned at the vehicle.

Abstract: A vehicular control system includes a camera having an exterior field of view at least forward of the vehicle. During a forward maneuver of the vehicle towing a trailer, the vehicular control system detects an object present exterior of the vehicle which ought not be impacted during the forward maneuver of the vehicle towing the trailer based at least in part on image processing by an image processor of image data captured by the camera. Responsive at least in part to detection of the object, the vehicular control system determines a forward driving path for the vehicle towing the trailer that avoids the detected object so that the trailer does not run over or contact the detected object. The vehicular control system determines the forward driving path at least in part responsive to (i) processing of captured image data and (ii) trailer data pertaining to physical characteristics of the trailer.

Abstract: A vehicular control system includes a camera having an exterior field of view at least rearward of the vehicle and operable to capture image data. A trailer is attached to the vehicle and image data captured by the camera includes image data captured when the vehicle is maneuvered with the trailer at an angle relative to the vehicle. The vehicular control system determines a path of the trailer responsive at least to a steering angle of the vehicle. The vehicular control system detects an object present exterior of the vehicle during maneuvering of the vehicle and the trailer and based at least in part on image processing of captured image data. The vehicular control system plans a driving path for the vehicle that avoids the detected object so that the vehicle and the trailer do not run over or contact the detected object.

Abstract: A vehicular camera calibration system includes a camera disposed at a vehicle and having a field of view exterior of the vehicle and being operable to capture image data. Responsive to processing of image data captured by the camera, the camera calibration system determines features at the ground adjacent to the vehicle and tracks the determined features over two or more frames of captured image data. Responsive to processing of frames of captured image data during movement of the vehicle along a straight path on a planar surface, the camera calibration system is operable to determine a misalignment of the camera. The camera calibration system calibrates the misaligned camera by using an assumption that the determined features lie in a plane parallel to the planar surface along which the vehicle is traveling. The camera calibration system calibrates the camera by reducing ambiguity in vectors normal to the planar surface.

Abstract: A method for calibrating a camera of a vehicular vision system includes capturing a first frame of image data by the camera during a first ignition cycle of the vehicle, and, responsive to ending the first ignition cycle of the vehicle, saving to memory the first frame of captured image data. A second frame of image data is captured by the camera during a second ignition cycle of the vehicle following the first ignition cycle. The first frame of captured image data is compared by an image processor to the second frame of captured image data to determine a change in orientation of the camera. Responsive to determination of the change in orientation of the camera, processing by the image processor of frames of image data captured by the camera during the second ignition cycle is adjusted to accommodate the determined change in orientation of the camera.

Abstract: A camera calibration method for calibrating at least one camera of a vehicle includes providing a target area for a vehicle to be positioned at, with the vehicle having a forward camera, a rearward camera and opposite side cameras. When the vehicle is positioned at the target area, a target is electronically generated at an area that is encompassed by the field of view of one of the cameras or at an overlapping portion of the fields of view of two of the cameras of the vehicle. Image data is captured by the two cameras that is representative of the generated target. Image data captured by the two cameras is processed to detect the target in the fields of view of the two cameras. At least one of the two cameras is calibrated responsive to detection of the target.

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.
