Abstract

In one embodiment, a towed implement proximity system, the system comprising: a first device comprising a transceiver, the first device configured to: transmit a signal; receive a first signal at a first angle and a second signal at a second angle responsive to the transmitted signal, the first and second signals comprising first information and second information, respectively, the first and second information each corresponding to respective positional information; and a controller coupled to the first device, the controller configured to determine a relative position in three axes between a first machine and a second machine based on the first and second information.

First claim

At least the following is claimed:

1. An articulated machine proximity system, the system comprising:
a first device comprising a transceiver, the first device configured to:
transmit a signal;
receive a first signal at a first angle and a second signal at a second angle responsive to the transmitted signal, the first and second signals comprising first information and second information, respectively, the first and second information each corresponding to respective positional information;

a controller coupled to the first device, the controller configured to determine a relative position in three axes between a first machine and a second machine based on the first and second information; and wherein the controller is configured to cause a component of the first machine to align with a component of the second machine along a first axis.

2. The system of claim 1 , wherein the controller is configured to determine the relative position based on a triangulation computation.

3. The system of claim 1 , wherein the three axes consist of pitch, roll, and yaw.

4. The system of claim 1 , wherein the first axis is either a horizontal axis or a vertical axis.

5. The system of claim 1 , wherein the controller is configured to alert an operator when the relative position between the first machine and the second machine closes to within a threshold distance.

6. The system of claim 5 , wherein the controller is configured to alert the operator by providing a visual alert, an audio alert, or a combination of both.

7. The system of claim 1 , wherein the controller is configured to automatically cause one of the first machine or the second machine to modify a current manner of movement responsive to the relative position between the first machine and the second machine closing to within a threshold distance.

8. The system of claim 7 , wherein the controller is further configured to alert an operator when the relative position between the first machine and the second machine closes to within a threshold distance.

9. The system of claim 1 , wherein the relative position between the first machine and the second machine comprises a relative position between a first component of a towing vehicle and a second component of a vehicle towed by the towing vehicle.

10. The system of claim 9 , wherein the first component comprises an unloading auger of a combine harvester machine and the second component comprises a frame of a baler.

11. The system of claim 1 , wherein the first device is configured to receive the first signal from a second target device and the second signal from a third target device.

12. The system of claim 11 , wherein the first device is located on the first machine embodied as a towing machine and the second and third devices are coupled to the second machine embodied as a towed machine.

13. The system of claim 11 , wherein the second and third devices are located on the first machine embodied as a towing machine and the first device is coupled to the second machine embodied as a towed machine.

14. The system of claim 1 , wherein the controller and the first device are co-located in a single integrated processing unit.

15. The system of claim 1 , wherein the first device is configured to transmit the signal as either a broadcast signal or a non-broadcast signal.

16. The system of claim 11 , further comprising one or more first additional devices of like-functionality to the first device and one or more second additional devices of like functionality to the second and third devices.

17. An articulated machine proximity system, the system comprising:
a controller configured to:
receive first information corresponding to a first set of positional information;
receive second information corresponding to a second set of positional information;
determine a relative position in three axes between a towing machine and a towed machine based on triangulation of the first and second information;
cause an action responsive to the determination, the action comprising one or more of:
alerting an operator when the relative position between the towed machine and the towing machine closes to within a threshold distance;
cause one of the towed machine or the towing machine to modify a current manner of movement responsive to the relative position between the towing machine and the towed machine closing to within the threshold distance; or
cause a component of the towing machine to align with a component of the towed machine along a first axis; and

plural transceiver devices located on the towed machine and at least one target device located on the towing vehicle, the plural transceiver devices configured to receive first and second signals corresponding to the first and second information, respectively, from the at least one target device, the first and second signals received at different angles, the plural transceiver devices configured to communicate the first and second information to the controller.

18. An articulated machine proximity method, the method comprising:
transmitting a signal;
receiving a first signal at a first angle and a second signal at a second angle responsive to the transmitted signal, the first and second signals comprising first information and second information, respectively, the first and second information each corresponding to respective positional information;
determining a relative position in three axes between a first machine and a second machine based on the first and second information; and using a controller to cause a component of the first machine to align with a component of the second machine along a first axis.

19. An articulated machine proximity system, the system comprising:
a first device comprising a transceiver, the first device configured to: transmit a signal;
receive a first signal at a first angle and a second signal at a second angle responsive to the transmitted signal, the first and second signals comprising first information and second information, respectively, the first and second information each corresponding to respective positional information;
a controller coupled to the first device, the controller configured to determine a relative position in three axes between a first machine and a second machine based on the first and second information; and
wherein the controller is configured to alert an operator when the relative position between the first machine and the second machine closes to within a threshold distance.
