Abstract
A method for dynamically calibrating a vehicular trailer angle detection system includes providing at least a rear camera at a rear portion of the vehicle. A trailer is hitched at the vehicle and the vehicle is driven forward while towing the trailer. The control determines an expected location of a portion of the trailer based on provided vehicle-trailer parameters as the vehicle is driven forward and towing the trailer. An actual location of the portion of the trailer is determined via processing at the control of captured image data as the equipped vehicle is driven forward and towing the trailer. The vehicular trailer angle detection system is calibrated responsive to determination, via processing at the control of captured image data as the equipped vehicle is driven forward and towing the trailer, that the determined actual location of the portion of the trailer is not at the determined expected location.
