Abstract

The present disclosure is directed to a system for controlling a plurality of machines. The system includes a camera disposed on a second machine and configured to record at least one image of a first machine. A controller is configured to be in communication with the first machine and the second machine. The controller is configured to track information associated with the recorded image of the first machine. The controller is also configured to determine a direction of movement of the second machine based on an analysis of the tracked information.

Claims

1. A system for controlling a plurality of machines, comprising:

a camera disposed on a second machine and configured to record at least one image of a first machine;

a controller in communication with the first machine and the second machine, the controller configured to;

track information associated with the recorded image of the first machine;

determine a direction of movement of the second machine based on an analysis of the tracked information.

2. The control system in claim 1, wherein the analysis includes a compare of current tracked information and prior tracked information associated with the first machine.

3. The control system of claim 1, wherein the controller is further configured to selectively communicate:

a first mode of operation in which the second machine follows the first machine based on the analysis of the tracked information; and

a second mode of operation in which the second machine moves based on a signal from the first set of operator input devices.

4. The control system of claim 1, further comprising:

a first set of operator input devices disposed on the first machine; and

a second set of operator input devices located on the first machine for controlling the movement of the first machine.

5. The control system of claim 4, wherein the first set of operator input devices includes controls for actuating at least one of a steering, braking, acceleration, or implement control system of the second machine.

6. The control system in claim 2, wherein the controller continuously updates memory with the current tracked information of the first machine.

7. The control system in claim 1, wherein the tracked information relates to distance, angle, orientation, and direction of movement of the first machine.

8. The control system of claim 1, further comprising:

an actuator system located on the second machine and configured to actuate at least one of a brake control system, an acceleration control system, and a steering control system of the second machine

9. The control system in claim 1, wherein the recorded image of the first machine is configured as a 2-dimensional image.

10. The control system in claim 9, wherein the recorded image of the first machine is stored as a 3-dimensional model in memory.

11. A method of controlling a plurality of machines, comprising:

recording at least one image of a first machine;

tracking information associated with the recorded image of the first machine; and

determining a direction of movement of a second machine based on an analysis of the tracked information.

12. The method of claim 11, wherein the analysis includes a compare of current tracked information and prior tracked information associated with the first machine.

13. The method of claim 11, further comprising:

selecting a first mode of operation or a second mode of operation;

controlling the second machine based on the analysis of the tracked information associated with the first machine when in the first mode of operation; and

controlling the second machine based on a signal received from the first machine when in the second mode of operation.

14. The method of claim 13, wherein the controlling of the second machine based on the analysis of the tracked information includes at least one of:

increasing and/or decreasing an engine torque and/or speed based on results of the analysis;

actuating a steering control system based on results of the analysis; and

actuating a braking control system based on results of the analysis.

15. The method of claim 11, wherein the tracked information relates to distance, angle, orientation, and direction of movement of the first machine.

16. The method of claim 11, wherein the tracked information relates to distance, angle, orientation, and direction of movement of the first machine.

17. The method of claim 11, further comprising:

actuating at least one of a brake control system, an acceleration control system, and a steering control system of the second machine based on the determining of the direction of movement of the second machine.

18. The method of claim 12, further comprising:

continuously updating a memory with the current tracked information of the first machine.

19. The method of claim 11, wherein the recorded image of the first machine is configured as a 2-dimensional image.

20. The method of claim 11, wherein the recorded image of the first machine is stored as a 3-dimensional model in memory.
