Abstract
A vehicular trailer assist system includes a control that includes an image processor for processing image data captured by the camera representative of at least a portion of a trailer hitched to the vehicle. The control determines whether the trailer has been previously hitched to the vehicle. Responsive to the trailer not being previously hitched, the control operates in a trailer initial calibration mode. Responsive to the control recognizing the trailer, the control operates in a recognized trailer calibration mode. The control obtains calibration data unique to the hitched trailer. The control, responsive to obtaining the calibration data, processes image data captured by the camera using the calibration data to locate the current position of the trailer relative to the vehicle. The control, responsive to locating the current position of the trailer relative to the vehicle, determines a trailer angle based on the located current position.
