Abstract

A hitch angle monitoring system and method are provided. A display shows an imaged scene of a hitch connection between a tow vehicle and a trailer. A processor is configured to superimpose an overlay on the imaged scene, wherein the overlay indicates a hitch angle position limit. A hitch angle position indicator is shown on the display and visually relates a current hitch angle position to the hitch angle position limit.

Claims (30)

1. A hitch angle monitoring system comprising:

a display for showing an imaged scene of a hitch connection between a tow vehicle and a trailer;

a processor configured to superimpose an overlay on the imaged scene, wherein the overlay indicates a hitch angle position limit; and

a hitch angle position indicator that is shown on the display and visually relates a hitch angle position to the hitch angle position limit.

2. The hitch angle monitoring system of claim 1 , wherein the hitch angle position corresponds to an angular position of a centerline longitudinal axis of the trailer relative to a centerline longitudinal axis of the tow vehicle.

3. The hitch angle monitoring system of claim 2 , wherein the hitch angle position indicator is one of an imaged object visible in the imaged scene and a virtual object that is overlaid on the imaged scene.

4. The hitch angle monitoring system of claim 3 , wherein the hitch angle position indicator coincides with the centerline longitudinal axis of the trailer and is positioned closer towards the hitch angle position limit when a hitch angle between the tow vehicle and the trailer increases.

5. The hitch angle monitoring system of claim 4 , wherein the overlay includes a plurality of regions, each encompassing at least one hitch angle position and each visibly distinguished by an associated color.

6. The hitch angle monitoring system of claim 4 , wherein the processor is further configured to generate a warning signal when the current hitch angle position nears, reaches, and/or exceeds the hitch angle position limit.

7. The hitch angle monitoring system of claim 1 , wherein the processor is further configured to superimpose a virtual steering input apparatus on the imaged scene that mimics the physical characteristics and behavior of an actual steering input apparatus of a trailer backup assist system.

8. A hitch angle monitoring system comprising:

a display for showing an imaged scene;

a processor configured to superimpose an overlay on the imaged scene that indicates a hitch angle position limit between a tow vehicle and a trailer; and

a hitch angle position indicator that is shown on the display and moves in relation to the hitch angle position limit based on a change in hitch angle between the tow vehicle and the trailer.

9. The hitch angle monitoring system of claim 8 , wherein the hitch angle position corresponds to an angular position of a centerline longitudinal axis of the trailer relative to a centerline longitudinal axis of the tow vehicle.

10. The hitch angle monitoring system of claim 9 , wherein the hitch angle position indicator moves within the overlay based on changes in a hitch angle between the tow vehicle and the trailer.

11. The system of 10 , wherein the hitch angle position indicator moves by way of angular displacement and coincides in position with a centerline axis of the trailer while being displaced.

12. The hitch angle monitoring system of claim 11 , wherein the overlay includes a plurality of regions, each encompassing at least one hitch angle position and each visibly distinguished by an associated color.

13. The hitch angle monitoring system of claim 11 , wherein the overlay includes a plurality of regions, each encompassing at least one hitch angle position and each visibly distinguished by an associated color.

14. The system of claim 8 , wherein the processor is further configured to generate a virtual steering input apparatus that is superimposed on the imaged scene and mimics the physical characteristics and behavior of an actual steering input apparatus of a trailer backup assist system.

15. A hitch angle monitoring method comprising the steps of:

imaging a rear vehicle scene;

displaying the imaged scene;

superimposing an overlay on the imaged scene that identifies a hitch angle position limit between a tow vehicle and a trailer; and

displaying a hitch angle position indicator that identifies a current hitch angle position in relation to the hitch angle limit position.

16. The hitch angle monitoring method of claim 15 , wherein the hitch angle position corresponds to an angular position of a centerline longitudinal axis of the trailer relative to a centerline longitudinal axis of the tow vehicle.

17. The hitch angle monitoring method of claim 16 , wherein the hitch angle position indicator coincides with the centerline longitudinal axis of the trailer and is positioned closer towards the hitch angle position limit when a hitch angle between the tow vehicle and the trailer increases.

18. The hitch angle monitoring method of claim 17 , wherein the overlay includes a plurality of regions, each encompassing at least one hitch angle position and each visibly distinguished by an associated color.

19. The hitch angle monitoring method of claim 18 , further comprising the step of generating a warning signal when the current hitch angle position nears, reaches, and/or exceeds the hitch angle position limit.

20. The hitch angle monitoring method of claim 19 , further comprising the step of generating a virtual steering input apparatus that is overlaid on the imaged scene and mimics the physical characteristics and behavior of an actual steering input apparatus of a trailer backup assist system.
