Abstract:
Methods and apparatus are provided for determining a hitch articulation angle including a camera for capturing a first image and a second image, a steering sensor configured to detect a steering angle, a velocity sensor configured to detect a vehicle velocity, a processor configured to for generating a bird's eye view of the first image and the second image through a perspective transform, generating a trailer hitch model from the first image in response to the steering angle and the vehicle velocity indicating a vehicle is traveling in a straight forward direction, generating a current hitch model from the second image, determining a hitch articulation angle in response to an angular difference between the trailer hitch model and the current hitch model, and a vehicle controller controlling the vehicle in response to the hitch articulation angle.
