Abstract

A system and method for driver guidance are presented. A position sensor is mounted to a vehicle. The position sensor is configured to identify a position of the vehicle and a heading of the vehicle. A device is configured to generate a plurality of outputs. A controller is connected to the position sensor and the display device. The controller is configured to access, via a wireless communications network, a database to identify a target loading location for the vehicle, determine a location and a heading of the target loading location for the vehicle, and modify at least one of the plurality of outputs of the display device based upon at least one of the location and the heading of the target loading location.

Claims

1. A system, comprising:

a position sensor mounted to a vehicle, the position sensor being configured to identify a position of the vehicle and a heading of the vehicle;

a display device configured to generate a plurality of visual outputs; and

a controller connected to the position sensor and the display device, the controller being configured to;

access, via a wireless communications network, a database to identify a target loading location for the vehicle,

determine a location and a heading of the target loading location for the vehicle,

compare the position of the vehicle to the location of the target loading location to determine a location offset,

compare the heading of the vehicle to the heading of the target loading location to determine a heading offset, and

modify at least one of the plurality of visual outputs of the display device based upon at least one of the location offset and the heading offset.

2. The system of claim 1, wherein the display device includes a plurality of lights and the controller is configured to illuminate a number of the plurality of lights based upon the location offset.

3. The system of claim 1, wherein the display device includes a plurality of lights and the controller is configured to:

determine a horizontal location offset by determining a difference between the location of the target loading location and the position of the vehicle in a direction perpendicular to the heading of the target loading location; and

illuminate a number of the plurality of lights based upon the horizontal location offset.

4. The system of claim 1, wherein the position sensor includes an electronic compass configured to determine the heading of the vehicle.

5. The system of claim 1, wherein the location and the heading of the target loading location for the vehicle are determined by an operator of a second vehicle.

6. The system of claim 5, wherein the second vehicle is a shovel and a location of the target loading location is determined by a loading radius of the shovel specified by the operator of the second vehicle.

7. The system of claim 5, wherein the second vehicle is a shovel and the heading of the target loading location is at least partially determined by an orientation of a bucket of the shovel when the bucket is positioned over the location of the target loading location.

8. A system, comprising:

a position sensor mounted to a vehicle, the position sensor being configured to identify a position of the vehicle and a heading of the vehicle;

an output device configured to generate a plurality of outputs; and

a controller connected to the position sensor and the output device, the controller being configured to;

access, via a wireless communications network, a database to identify a target location for the vehicle,

determine a location and a heading of the target location for the vehicle, and

modify at least one of the plurality of outputs of the output device based upon at least one of the location and the heading of the target location.

9. The system of claim 8, wherein the controller is configured to:

compare the position of the vehicle to the location of the target location to determine a location offset; and

modify the at least one of the plurality of outputs of the output device based upon the location offset.

10. The system of claim 9, wherein the controller is configured to:

compare the heading of the vehicle to the heading of the target location to determine a heading offset, and

modify the at least one of the plurality of outputs of the output device based upon the heading offset.

11. The system of claim 8, wherein the output device includes a plurality of lights and the controller is configured to illuminate a number of the plurality of lights based upon the at least one of the location and the heading of the target location.

12. The system of claim 11, wherein the output device includes a plurality of lights and the controller is configured to:

determine a horizontal location offset by determining a difference between the location of the target location and the position of the vehicle in a direction perpendicular to the heading of the target location; and

illuminate a number of the plurality of lights based upon the horizontal location offset.

13. The system of claim 8, wherein the position sensor includes an electronic compass configured to determine the heading of the vehicle.

14. The system of claim 8, wherein the location and the heading of the target location for the vehicle are determined by an operator of a second vehicle.

15. The system of claim 14, wherein the second vehicle is a shovel and a location of the target location is determined by a loading radius of the shovel specified by the operator of the second vehicle.

16. The system of claim 14, wherein the second vehicle is a shovel and the heading of the target location is at least partially determined by an orientation of a bucket of the shovel when the bucket is positioned over the location of the target location.

17. A method, comprising:

accessing, via a wireless communications network, a database to identify a target loading location for a vehicle, the vehicle including a position sensor mounted to a vehicle, the position sensor being configured to identify a position of the vehicle and a heading of the vehicle,

determining a location and a heading of the target loading location for the vehicle,

comparing the position of the vehicle to the location of the target loading location to determine a location offset,

comparing the heading of the vehicle to the heading of the target loading location to determine a heading offset, and

generating an output on a display device based upon at least one of the location offset and the heading offset.

18. The method of claim 17, wherein the display device includes a plurality of lights, and including illuminating a number of the plurality of lights based upon the location offset.

19. The method of claim 17, wherein the display device includes a plurality of lights, and including:

determining a horizontal location offset by calculating a difference between the location of the target loading location and the position of the vehicle in a direction perpendicular to the heading of the target loading location; and

illuminating a number of the plurality of lights based upon the horizontal location offset.
