Systems and method for control of a power take-off clutch

1. A method, comprising:

measuring a parameter indicative of a measured torque in a PTO clutch;

determining an incremental torque based at least in part on proportional-integral-derivative (PID) control logic;

determining a command torque, wherein the command torque is a sum of the measured torque and the incremental torque;

generating a control signal, wherein a current of the control signal corresponds to the command torque and a pressure in a cylinder of the PTO clutch;

providing the control signal to the PTO clutch;

reducing the incremental torque if an engagement power exceeds an engine power output; and

ceasing engagement if an energy absorbed by the clutch exceeds an energy rating of the PTO clutch.

2. The method of claim 1 , wherein the incremental torque is also based on a desired engagement aggressiveness type.

3. The method of claim 2 , wherein the engagement aggressiveness type comprises a high aggressive engagement type, a medium aggressive engagement type, and a low aggressive engagement type.

4. The method of claim 2 , wherein the engagement aggressiveness type, is based, at least in part, on the elapsed time during engagement.

5. The method of claim 1 , comprising operating an actuator to control the pressure in the cylinder based at least in part on the control signal.

6. The method of claim 5 , wherein the actuator comprises a solenoid coupled to a valve.

7. The method of claim 1 , comprising:

determining a gear ratio across the PTO clutch;

increasing the current of the control signal over a given period of time once the gear ratio across the PTO clutch reaches a threshold value.

8. The method of claim 1 , wherein the engine is disposed within an agricultural vehicle.

9. A non-transitory computer readable medium comprising executable instructions that when executed cause a processor to:

determine an incremental torque based at least in part on proportional-integral-derivative (PID) control logic;

determine a command torque, wherein the command torque is a sum of a current torque and the incremental torque, wherein the current torque is determined based on a measure parameter indicative of the current torque;

generate a control signal, wherein the current of the control signal corresponds to the command torque and a pressure in a cylinder of the PTO clutch;

provide the control signal to the PTO clutch;

reduce the incremental torque if an engagement power exceeds an engine power output; and

cease engagement if an energy absorbed by the clutch exceeds an energy rating of the PTO clutch.

10. The non-transitory computer readable medium of claim 9 , wherein the incremental torque is also based on a desired engagement aggressiveness type.

11. The non-transitory computer readable medium of claim 10 , wherein the engagement aggressiveness type comprises a high aggressive engagement type, a medium aggressive engagement type, and a low aggressive engagement type.

12. The non-transitory computer readable medium of claim 10 , wherein the engagement aggressiveness type, is based, at least in part, on the elapsed time during engagement.

13. The non-transitory computer readable medium of claim 9 , wherein the control signal provides instructions to an actuator to control the pressure in the cylinder based at least in part on the control signal.

14. The non-transitory computer readable medium of claim 9 , wherein the non-transitory computer readable medium is disposed within an agricultural vehicle.

15. A system, comprising:

a PTO clutch configured to couple and decouple a PTO shaft and a drive shaft, wherein the PTO clutch comprises:

a cylinder;

a piston disposed within the cylinder;

a valve fluidly coupled to the cylinder and configured to restrict or allow fluid flow between the cylinder and a fluid reservoir; and

a solenoid coupled to the valve and configured to control a position of the valve;

a controller in communication with the solenoid, wherein the controller is configured to:

receive a current torque in a PTO clutch, wherein the current torque is based on a measured parameter indicative of the current torque in the PTO clutch;

determine an incremental torque based at least in part on PID control logic;

determine a command torque, wherein the command torque is a sum of a current torque and the incremental torque;

generate a control signal, wherein a current of the control signal corresponds to the command torque and a pressure in a cylinder of the PTO clutch;

provide the control signal to the solenoid;

reduce the incremental torque if an engagement power exceeds an engine power output; and

cease engagement if an energy absorbed by the clutch exceeds an energy rating of the PTO clutch.

16. The system of claim 15 , wherein the incremental torque is also based on a desired engagement aggressiveness type.

17. The system of claim 16 , wherein the engagement aggressiveness type comprises a high aggressive engagement type, a medium aggressive engagement type, and a low aggressive engagement type.

18. The system of claim 16 , wherein the engagement aggressiveness type, is based, at least in part, on the elapsed time during engagement.

19. The system of claim 15 , wherein the engine is disposed within an agricultural vehicle.

20. The system of claim 15 , wherein the PTO shaft powers and agricultural implement.
