Abstract

A work vehicle guidance display system comprising: at least one imaging device disposed on a work vehicle; a display disposed in the work vehicle configured to display images from the imaging device; and a controller configured to: select a field of view of the imaging device to display; receive a static dimension associated with the work vehicle; receive a dynamic dimension associated with the work vehicle; and display on the display a field view with a first machine travel path based on the static dimension and a second machine travel path based on the dynamic dimension.

First claim

What is claimed is:

1. A work vehicle guidance display system comprising:
at least one imaging device disposed on a work vehicle;
a display disposed in the work vehicle configured to display images from the imaging device; and
a controller configured to:
select a field of view of the imaging device to display;
receive at least two static dimensions associated with the work vehicle;
receive at least two dynamic dimensions associated with the work vehicle; and
display on the display a field of view the greater of a first machine travel path based on the static dimensions and a second machine travel path based on the dynamic dimensions.

2. The system of claim 1 wherein the work vehicle comprises a first fixed portion and a second moveable portion, the first fixed portion having at least one of the static dimensions and the second moveable portion having at least one of the dynamic dimensions.

3. The system of claim 2 wherein the controller is configured to display a first travel path for the first fixed portion and a second travel path for the second moveable portion.

4. The system of claim 2 wherein the movement of the second moveable portion is determined using a rotation sensor associated with the work vehicle, the rotation sensor determining a rotation angle.

5. The system of claim 3 wherein the first travel path displayed on the display changes depending upon the movement of the first fixed portion.

6. The system of claim 5 wherein the second travel path displayed on the display changes depending upon the movement of the second moveable portion and the first fixed portion.

7. The system of claim 1 further comprising an inertial measurement unit associated with the work vehicle, the inertial measurement unit sensing at least one of pitch, yaw and roll of the work vehicle.

8. The system of claim 7 wherein the controller is configured to generate the first and second travel paths using a signal from the inertial measurement unit.

9. The system of claim 1 wherein the controller is configured to recognize an obstacle within the field of view and provide a first warning to an operator of the work vehicle if the obstacle is within the first machine travel path of the work vehicle.

10. The system of claim 1 wherein the controller is configured to recognize an obstacle within the field of view and provide a second warning to an operator of the work vehicle if the obstacle is within the second machine travel path of the work vehicle.

11. The system of claim 1 wherein the controller is configured to transmit the field of view from the imaging device, the static dimensions and the dynamic dimensions to an offboard processor, the offboard processor configured to select the field of view, overlay the first and second machine travel paths onto the field view and transmit to the display on the work vehicle.

12. The system of claim 1 further comprising an obstacle detection sensor disposed on the work vehicle, the obstacle detection configured to detect presence of an obstacle within the machine travel path.

13. The system of claim 1 wherein the display is at least one of a plasma display panel, liquid crystal display panel, light-emitting diode, or holographic projection.

14. The system of claim 1 wherein the imaging device is disposed to provide at least one of a forward field of view, rearward field of view, and opposing side fields of view.

15. The system of claim 1 wherein the controller is configured to determine an operating state of the vehicle in response to the static dimensions and dynamic dimensions.

16. The system of claim 1 wherein the controller is configured to display the future position of the work vehicle in response to the static dimensions and dynamic dimensions.

17. The system of claim 1 wherein the controller is configured to receive a velocity of the work vehicle.

18. A method for displaying work vehicle travel paths, the method comprising:
selecting, with a controller on the work vehicle, a field of view from a plurality of imaging devices associated with the work vehicle;
generating, with the controller, a first machine travel path based on the greater of at least two static dimensions associated with the work vehicle;
generating, with the controller, a second machine travel path based on the greater of at least two dynamic dimensions associated with the work vehicle; and
displaying, on a display within work vehicle, the field of view with the first machine travel path and the second machine travel path.

19. A work vehicle guidance display system comprising:
at least one imaging device disposed on a work vehicle;
a display disposed in the work vehicle configured to display images from the imaging device; and
a controller configured to:
select a field of view of the imaging device to display;
receive a first static dimension associated with the work vehicle;
receive a second static dimension associated with the work vehicle;
receive a first dynamic dimension associated with the work vehicle;
receive a second dynamic dimension associated with the work vehicle;
generate travel paths for each of the first and second static and dynamic dimensions; and
transmit to the display, the greater of the travel paths for each of the first and second static and dynamic dimensions.
