Abstract
A trailer backup assist system is provided herein. A camera captures images of a trailer connected to a vehicle. A display has a screen for displaying captured images and registering a touch event thereon to assign a target on the imaged trailer. A controller processes the captured images and tracks the target to determine a hitch angle between the vehicle and the trailer while the vehicle is automatically steered during a trailer backup maneuver.
Claims18
A trailer backup assist system comprising:
- a camera for capturing images of a trailer connected to a vehicle;
- a display having a screen for displaying captured images and registering a touch event thereon to assign a target on the trailer;
- and
- a controller for processing the captured images and tracking the target to determine a hitch angle between the vehicle and the trailer while the vehicle is automatically steered during a trailer backup maneuver, wherein the hitch angle is determined based on changes in pixels of the captured images that relate to an angular position change of the target.

A trailer backup assist system comprising:
- a camera for capturing images of a trailer connected to a vehicle;
- and
- a controller for processing the captured images and tracking a target on the trailer to determine a hitch angle between the vehicle and the trailer during a trailer backup maneuver, wherein if the target becomes lost, the controller calculates a time in which to reach a maximum controllable hitch angle at a current trailer yaw rate.
A hitch angle monitoring method, comprising the steps of:
- capturing images of a trailer that is connected to a vehicle;
- displaying the captured images on a screen of a vehicle display;
- registering a touch event on the screen to assign a target on the trailer;
- and
- processing the captured images to track the target to determine a hitch angle between the vehicle and the trailer while the trailer is automatically steered during a trailer backup maneuver, wherein the target comprises a number of points on the trailer, wherein the points correspond to objects or features of the trailer, and wherein the hitch angle is determined based on changes in pixels of the captured images that relate to an angular position change of the target.
