Abstract

A method includes receiving a first signal indicative of an implement pitch angle from a sensor, determining whether the pitch angle is within a pitch angle range, generating a first control signal indicative of instructions to adjust a hitch actuator if the pitch angle is not within the pitch angle range, and communicating the first control signal to the hitch actuator.

Claims (62)

1. A method, comprising:

receiving a first signal indicative of an implement pitch angle from a sensor;

determining whether the pitch angle is within a pitch angle range;

generating a first control signal indicative of instructions to adjust a hitch actuator if the pitch angle is not within the pitch angle range; and

communicating the first control signal to the hitch actuator.

2. The method of claim 1 , wherein generating the first control signal comprises:

determining a desired hitch height to achieve a desired implement pitch angle within the pitch angle range;

determining a desired hitch actuator position that corresponds to the desired hitch height; and

generating the first control signal indicative of instructions to extend or contract the hitch actuator to the desired hitch actuator position.

3. The method of claim 2 , wherein the first control signal is based on the implement pitch angle, and a distance between an implement frame and one or more wheel assemblies of an implement.

4. The method of claim 1 , comprising:

receiving a second signal indicative of an implement height from the sensor;

determining whether the implement height is within an implement height range;

generating a second control signal indicative of instructions to adjust the hitch actuator and a third control signal indicative of instructions to adjust an implement actuator, if the implement height is not within the implement height range;

communicating the second control signal to the hitch actuator; and

communicating the third control signal to the implement actuator.

5. The method of claim 4 , wherein generating the second control signal comprises:

determining a desired hitch height to achieve a desired implement height within the implement height range;

determining a desired hitch actuator position that corresponds to the desired hitch height; and

generating the second control signal indicative of instructions to extend or contract the hitch actuator to the desired hitch actuator position.

6. The method of claim 4 , wherein generating the third control signal comprises:

determining an implement actuator position to achieve a desired implement height within the implement height range; and

generating the third control signal indicative of instructions to extend or contract the implement actuator to the desired implement actuator position.

7. The method of claim 4 , wherein the first, second, and third control signals are generated by an implement controller.

8. The method of claim 1 , wherein the first control signal is communicated via an ISOBUS Class 3 communication protocol.

9. A method, comprising:

receiving a first signal indicative of an implement height from a sensor;

determining whether the implement height is within an implement height range;

generating a first control signal indicative of instructions to adjust a hitch actuator and a second control signal indicative of instruction to adjust an implement actuator, if the implement height is not within the implement height range;

communication the first control signal to the hitch actuator; and

communicating the second control signal to the implement actuator;

receiving a second signal indicative of an implement pitch angle from the sensor;

determining whether the implement pitch angle is within a pitch angle range;

generating a third control signal indicative of instructions to adjust the hitch actuator if the pitch angle is not within the pitch angle range; and

communicating the third control signal to the hitch actuator.

10. The method of claim 9 , wherein generating the third control signal comprises:

determining a desired hitch height to achieve a desired implement pitch angle within the pitch angle range;

determining a desired hitch actuator position that corresponds to the desired hitch height; and

generating the first control signal indicative of instructions to extend or contract the hitch actuator to the desired hitch actuator position.

11. The method of claim 10 , wherein the third control signal is based on the implement pitch angle, and a distance between an implement frame and one or more wheel assemblies of an implement.

12. A method, comprising:

receiving a first signal indicative of an implement pitch angle from a sensor;

receiving a second signal indicative of an implement height from the sensor;

determining whether the pitch angle is within a pitch angle range;

determining whether the implement height is within an implement height range;

generating a first control signal indicative of instructions to adjust a hitch actuator if the pitch angle is not within the pitch angle range;

generating a second control signal indicative of instructions to adjust the hitch actuator and a third control signal indicative of instructions to adjust an implement actuator, if the implement height is not within the implement height range;

communicating the first control signal to the hitch actuator;

communicating the second control signal to the hitch actuator; and

communicating the third control signal to the implement actuator.

13. The method of claim 12 , wherein generating the first control signal comprises:

determining a desired hitch height to achieve a desired implement pitch angle within the pitch angle range;

determining a desired hitch actuator position that corresponds to the desired hitch height; and

generating the first control signal indicative of instructions to extend or contract the hitch actuator to the desired hitch actuator position.

14. The method of claim 13 , wherein the first control signal is based on the implement pitch angle, and a distance between an implement frame and one or more wheel assemblies of an implement.

15. The method of claim 12 , wherein generating the second control signal comprises:

determining a desired hitch height to achieve a desired implement height within the implement height range;

determining a desired hitch actuator position that corresponds to the desired hitch height; and

generating the second control signal indicative of instructions to extend or contract the hitch actuator to the desired hitch actuator position.

16. The method of claim 12 , wherein generating the third control signal comprises:

determining an implement actuator position to achieve a desired implement height within the implement height range; and

generating the third control signal indicative of instructions to extend or contract the implement actuator to the desired implement actuator position.
