Abstract

A calibration system for an agricultural vehicle includes: a motor-driven component; a motor coupled to the motor-driven component and configured to move the motor-driven component between a maximum distance position and a home position; and a controller operatively coupled to the motor. The controller is configured to: enter a component calibration mode; output a first movement signal to the motor to cause the motor to carry the motor-driven component toward the maximum distance position; determine that the motor-driven component has reached the maximum distance position; output a second movement signal to the motor to cause the motor to carry the motor-driven component toward the home position; and determine that the motor-driven component has reached the home position.

First claim

What is claimed is:

1. A calibration system for an agricultural vehicle, comprising:
a motor-driven component;
a motor coupled to the motor-driven component and configured to move the motor-driven component between a maximum distance position and a home position; and
a controller operatively coupled to the motor, the controller being configured to:
enter a component calibration mode;
output a first movement signal to the motor to cause the motor to move the motor-driven component toward the maximum distance position;
determine that the motor-driven component has reached the maximum distance position;
output a second movement signal to the motor to cause the motor to move the motor-driven component toward the home position;
output a safety query signal to a display prior to outputting the first movement signal or outputting the second movement signal, wherein a confirmation icon presented on the display must be selected before the controller outputs the first movement signal or the second movement signal; and
determine that the motor-driven component has reached the home position.

2. The calibration system of claim 1 , wherein the controller is configured to determine that the motor-driven component has reached the maximum distance position and the home position by sensing the presence of a current spike at each respective position.

3. The calibration system of claim 2 , wherein the controller is configured to control a supply of electrical power to the motor.

4. The calibration system of claim 1 , further comprising a first position sensor that is operatively coupled to the controller and configured to output a maximum distance position signal to the controller when the motor-driven component reaches the maximum distance position.

5. The calibration system of claim 4 , further comprising a second position sensor that is operatively coupled to the controller and configured to output a home position signal to the controller when the motor-driven component reaches the home position.

6. The calibration system of claim 1 , wherein the motor-driven component is a duckbill, a twine arm, or a cutter.

7. The calibration system of claim 1 , wherein the controller is further configured to record at least one first parameter corresponding to the motor-driven component reaching the maximum distance position and record at least one second parameter corresponding to the motor-driven component reaching the home position.

8. An agricultural vehicle, comprising:
a chassis;
a baling chamber carried by the chassis;
a motor-driven component carried by the chassis;
a motor coupled to the motor-driven component and configured to move the motor-driven component between a maximum distance position and a home position;
a display; and
a controller operatively coupled to the motor and the display, the controller being configured to:
enter a component calibration mode;
output a first movement signal to the motor to cause the motor to move the motor-driven component toward a maximum distance position;
determine that the motor-driven component has reached the maximum distance position;
output a home movement signal to the motor to cause the motor to move the motor-driven component toward the home position;
output a safety query signal to the display prior to outputting the first movement signal or outputting the home movement signal, wherein a confirmation icon presented on the display must be selected before the controller outputs the first movement signal or the home movement signal; and
determine that the motor-driven component has reached the home position.

9. The agricultural vehicle of claim 8 , wherein the controller is configured to determine that the motor-driven component has reached the maximum distance position and the home position by sensing the presence of a current spike at each respective maximum distance position.

10. The agricultural vehicle of claim 9 , wherein the controller is configured to control a supply of electrical power to the motor.

11. The agricultural vehicle of claim 8 , further comprising a first position sensor that is operatively coupled to the controller and configured to output a maximum distance position signal to the controller when the motor-driven component reaches the maximum distance position.

12. The agricultural vehicle of claim 11 , further comprising a second position sensor that is operatively coupled to the controller and configured to output a home position signal to the controller when the motor-driven component reaches the home position.

13. The agricultural vehicle of claim 8 , wherein the motor-driven component is a duckbill, a twine arm, or a cutter.

14. The agricultural vehicle of claim 8 , wherein the controller is further configured to record at least one first parameter corresponding to the motor-driven component reaching the maximum distance position and record at least one second parameter corresponding to the motor-driven component reaching the home position.

15. A method of calibrating a motor-driven component of an agricultural vehicle, the motor-driven component being coupled to a motor and movable to a maximum distance position and a home position, the method being performed by a controller and comprising:
outputting a first movement signal to the motor to move the motor-driven component to the maximum distance position;
determining that the motor-driven component has reached the maximum distance position;
outputting a second movement signal to the motor to move the motor-driven component to the home position;
outputting a safety query signal to a display prior to outputting the first movement signal or outputting the second movement signal, wherein a confirmation icon presented on the display must be selected before the controller outputs the first movement signal or the second movement signal; and
determining that the motor-driven component has reached the home position.

16. The method of claim 15 , wherein determining that the motor-driven component has reached the maximum distance position or determining that the motor-driven component has reached the home position comprises sensing the presence of a current spike corresponding to the motor-driven component reaching the maximum distance position or the home position.

17. The method of claim 15 , further comprising:
recording at least one first parameter corresponding to the motor-driven component reaching the maximum distance position; and
recording at least one second parameter corresponding to the motor-driven component reaching the home position.
