Abstract

A path input system is provided. The path input system includes at least one imaging device for generating image data. A GPS device is included for generating satellite image data. A controller generates an aerial view of a vehicle and a trailer based on the image data and the satellite data. A display is included for displaying the aerial view and registering a touch event thereon that inputs an intended path for the vehicle and the trailer.

First claim

What is claimed is:

1. A path input system comprising:
a controller for generating an aerial view of a vehicle; and
a display having a touch screen for displaying the aerial view and registering a touch event thereon that traces an intended backing path for the vehicle and the trailer, wherein unobstructed portions and obstructed portions of the intended backing path are displayed in different colors, and wherein the touch event further comprises dragging an obstructed portion of the intended backing path to modify a path curvature of the intended backing path.

2. The system of claim 1 , wherein the controller is configured to determine whether an unacceptable path condition is present and generate a warning indicating the presence of the unacceptable path condition.

3. The system of claim 2 , wherein the unacceptable path condition comprises one of a traced portion of the intended backing path resulting in a hitch angle between the vehicle and the trailer exceeding a maximum hitch angle and one or more obstacles blocking a traced portion of the intended backing path.

4. The system of claim 1 , wherein the controller is configured to automatically adjust a path curvature of the intended backing path to avoid an unacceptable path condition.

5. The system of claim 1 , wherein the controller is configured to generate one or more possible backing paths that are displayed alongside the intended backing path.

6. A path input system comprising:
a controller for generating an aerial view of a vehicle and a trailer; and
a display for displaying the aerial view on a touch screen configured to register a first touch event thereon that traces an intended backing path for the vehicle and the trailer and a second touch event thereon that modifies the intended backing path by dragging an obstructed portion of the intended backing path.

7. The system of claim 6 , wherein the controller is configured to determine whether an unacceptable path condition is present and generate a warning indicating the presence of the unacceptable path condition.

8. The system of claim 7 , wherein the unacceptable path condition comprises one of a traced portion of the intended backing path resulting in a hitch angle between the vehicle and the trailer exceeding a maximum hitch angle and one or more obstacles blocking a traced portion of the intended backing path.

9. The system of claim 6 , wherein the controller is configured to automatically adjust a path curvature of the intended backing path to avoid an unacceptable path condition.

10. The system of claim 6 , wherein the controller is configured to generate one or more possible backing paths that are displayed alongside the intended backing path.

11. The system of claim 6 , wherein the controller is configured to save the intended backing path for later use.

12. The system of claim 6 , wherein the obstructed portion of the intended backing path is displayed in a color that is visually distinguishable from a color used to display an unobstructed portion of the intended backing path.

13. A path input system comprising:
a controller for generating an aerial view of a vehicle and a trailer; and
a display for displaying the aerial view on a touch screen configured to register a touch event thereon that traces an intended backing path for the vehicle and the trailer, wherein the controller is configured to determine whether an unacceptable path condition is present and generate a warning indicating the presence of the unacceptable path condition, and wherein the touch screen is further configured to register a touch event thereon that drags an obstructed portion of the intended backing path to modify a path curvature of the intended backing path.

14. The system of claim 13 , wherein the obstructed portion of the intended backing path is displayed in a color that is visually distinguishable from a color used to display an unobstructed portion of the intended backing path.

15. The system of claim 13 , wherein the unacceptable path condition comprises one of a traced portion of the intended backing path resulting in a hitch angle between the vehicle and the trailer exceeding a maximum hitch angle and one or more obstacles blocking a traced portion of the intended backing path.

16. The system of claim 13 , wherein the controller is configured to automatically adjust a path curvature of the intended backing path to avoid an unacceptable path condition.

17. The system of claim 13 , wherein the controller is configured to generate one or more possible backing paths that are displayed alongside the intended backing path.

18. The system of claim 13 , wherein the controller is configured to save the intended backing path for later use.
