Abstract

Systems and methods for controlling formation of a windrow in response to a single control input. The single control input represents a desired windrow width. The single control input is used to determine positions of components of a cutter implement, such as side shields and a swath flap, that are used to form a windrow having the desired windrow width represented or that is otherwise associated with the single control input.

First claim

What is claimed is:

1. A system for controlling a width of a windrow using a single user input, the system comprising:
a cutter implement comprising:
side shields lateral offset from each other, the side shields moveable within a first range;
a swath flap extending laterally between the side shields, the swath flap movable within a second range, the side shields movable to a first position within the first range and the swath flap movable to a second position within the second range in response to a single control input;
wherein the single control input defines a selected windrow width,
wherein a plurality of position combinations of the swath flap and the side shield along the first range and the second range, respectively, define the selected windrow width, and
wherein the plurality of position combinations are selectable in a pre-determined sequence that is based on a grid location of the plurality of position combinations in a lookup table.

2. The system of claim 1 , wherein the single control input defines a desired width of a windrow to be produced by the cutter implement, and
wherein movement of the side shields to the first position within first range and movement of the swath flap to the second position within the second range in response to the single control input produces a windrow having the desired width during an agricultural operation.

3. The system of claim 2 , further comprising a feedback system comprising:
an optical sensor that detects a width of the produced windrow; and
a computer-implemented controller that compares the detected width of the produced windrow with the desired width, detects a variance between the detected width and the desired width; and alters a position of one of the side shields and the swath flap to reduce or eliminate the variance.

4. The system of claim 3 , wherein the optical sensor comprises a camera.

5. The system of claim 4 , wherein the camera comprises a stereo camera.

6. The system of claim 1 , further comprising an input device that receives the single control input.

7. The system of claim 6 , further comprising a computer-implemented controller coupled to the input device, wherein the computer-implemented controller determines the first position of the side shields in response to receipt of the single control input and determine the second position of the swath flap in response to receipt of the single control input, generates a first control signal that defines a movement of the side shields to the first position, and generates a second control signal that defines a movement of the swath flap to the second position.

8. The system of claim 7 , further comprising at least one first actuator coupled to the side shields and a second actuator coupled to the swath flap, wherein the at least one first actuator receives the first control signal and displace the side shields to the first position in response to the first control signal, and wherein the second actuator receives the second control signal and displaces the swath flap to the second position in response to the second control signal.

9. The system of claim 1 , wherein the first position of the side shields and the second position of the swath flap are correlated to produce a windrow having a desired width during an agricultural operation.

10. The system of claim 9 , wherein the correlation comprises one of a lookup table or a mathematical relationship.

11. A computer-implemented method for controlling a width of a windrow using a single user input, the method comprising:
receiving a single control input by an input device, the single control input representing a desired width of a windrow produced by a cutter implement;
determining, with an electronic processor, a first target position of side shields of the cutter implement in response to the received single control input;
determining, with the electronic processor, a second target position of a swath flap of the cutter implement in response to the received single input;
displacing the side shields to the first target position; and
displacing the swath flap to the second target position;
wherein a plurality of combinations of positions of the swath flap and the side shields define the desired width of the windrow, and wherein the plurality of position combinations are selectable in a pre-determined sequence that is based on a grid location of the plurality of position combinations in a lookup table.

12. The computer-implemented method of claim 11 , further comprising:
detecting, with at least one first position sensor, a first position of the side shields; and
detecting, with a second position sensor, a second position of the swath flat, wherein displacing the side shields to the first target position comprises displacing the side shields from the first position to the first target position, and
wherein displacing the swath flap to the second target position comprises displacing the swath flap from the second position to the second target position.

13. The computer-implemented method of claim 11 , further comprising:
detecting a width of a windrow produced by the cutter implement;
comparing the detected width to the desired width;
determining a variance based on the comparison of the detected with and the selected width; and
moving at least one of the side shields and the swath flap to reduce or eliminate the variance.

14. The computer-implemented method of claim 13 , wherein detecting a width of the windrow produced by the cutter implement comprises sensing the windrow with an optical sensor.

15. The computer-implemented method of claim 13 , wherein the optical sensor comprises a camera.

16. The computer-implemented method of claim 15 , wherein the camera comprises a stereo camera.

17. The computer-implemented method of claim 11 , wherein determining the first target position of side shields of the cutter implement in response to the received single control input comprises using the lookup table to identify the first target position and wherein determining the second target position of the swath flap of the cutter implement in response to the received single input comprises using the lookup table to identify the second target position.

18. The computer-implemented method of claim 11 , wherein receiving the single control input that represents the desired width of the windrow produced by the cutter implement comprises receiving the single control input via a user interface.

19. The computer-implemented method of claim 11 , wherein displacing the side shields to the first target position comprises actuating at least one first actuator in response to a received first control signal and wherein displacing the swath flap to the second target position comprises actuating a second actuator in response to a received second control signal.

20. The computer-implemented method of claim 11 , wherein the first target position of the side shields and the second target position of the swath flap are correlated to produce a windrow having the desired width during an agricultural operation.

21. The computer-implemented method of claim 11 , wherein as an operator cycles through the plurality of position combinations, the electronic processor moves to the next grid location in the pre-programmed sequence.

22. The computer-implemented method of claim 11 , wherein the pre-determined sequence that is based on grid location of the plurality of position combinations in the lookup table moves from one corner of the loo
