Agricultural vehicle having a brake pedal interface for controlling an application boom
According to an aspect of the invention, the brake pedal of an agricultural vehicle can be used as an interface to control auto fold/unfold sequences on a sprayer. This can allow functionality to be moved from a button, such as on the armrest, to the brake pedal using a controller, sensing and software. In one aspect, a button on the armrest can start the sequence, as long as the brake pedal is depressed. After the button is pressed, the operator can remove his hand from the button, but maintain the brake pedal depressed. If the operator lifts his foot off of the pedal, or initiates a different boom control button press, the sequence can stop. This can advantageously allow the operator to have the use of his hands during the sequence.
1. A system for controlling an application boom mounted to an agricultural vehicle, comprising:
an application boom configured to deliver agricultural product to a field, the application boom having a plurality of actuators configured to fold and unfold the boom relative to the agricultural vehicle;
a brake pedal for braking the agricultural vehicle when the brake pedal is depressed; and
a controller in communication with the plurality of actuators and the brake pedal, the controller having a processor executing a program stored in a non-transient medium operable to:
receive a command to fold or unfold the boom relative to the agricultural vehicle; and
following the command, control the plurality of actuators to fold or unfold the boom relative to the agricultural vehicle while the brake pedal is depressed and cease to fold or unfold the boom relative to the agricultural vehicle when the brake pedal ceases to be depressed.
2. The system of claim 1 , further comprising a button accessible to a user in an operator cab of the agricultural vehicle, wherein the controller receives the command upon actuation of the button.
3. The system of claim 2 , wherein the button is arranged on an armrest.
4. The system of claim 1 , wherein the application boom comprises left and right boom arms coupled to a center section in which the left boom arm folds or unfolds relative to a left side of the agricultural vehicle and the right boom arm folds or unfolds relative to a right side of the agricultural vehicle.
5. The system of claim 4 , wherein each boom arm comprises a plurality of segments with an actuator of the plurality of actuators being configured to move each segment.
6. The system of claim 5 , wherein the plurality of segments consists of three booms segments.
7. The system of claim 4 , wherein the plurality of actuators comprises a first actuator configured to tilt the left boom arm and a second actuator configured to tilt the right boom arm.
8. The system of claim 4 , wherein the plurality of actuators comprises at least one actuator configured to raise the center section to fold the boom or lower the center section to unfold the boom.
9. The system of claim 1 , further comprising the controller being operable to unfold the boom to a predetermined position defined by a user, the predetermined position comprising tilt and height of the boom as configured by the user.
10. An agricultural vehicle comprising:
a chassis;
wheels supporting the chassis for moving the vehicle;
an application boom supported by the chassis, the application boom being configured to deliver agricultural product to a field, the application boom having a plurality of actuators configured to fold and unfold the boom relative to the agricultural vehicle;
an operator cab supported by the chassis, the operator cab having a brake pedal for braking the agricultural vehicle when depressed; and
a controller in communication with the plurality of actuators and the brake pedal, the controller having a processor executing a program stored in a non-transient medium operable to:
receive a command to fold or unfold the boom relative to the agricultural vehicle; and
following the command, control the plurality of actuators to fold or unfold the boom relative to the agricultural vehicle while the brake pedal is depressed and cease to fold or unfold the boom relative to the agricultural vehicle when the brake pedal ceases to be depressed.
11. The agricultural vehicle of claim 10 , further comprising a button accessible to a user in the operator cab, wherein the controller receives the command upon actuation of the button.
12. The agricultural vehicle of claim 11 , wherein the button is arranged on an armrest.
13. The agricultural vehicle of claim 10 , wherein the application boom comprises left and right boom arms coupled to a center section in which the left boom arm folds or unfolds relative to a left side of the agricultural vehicle and the right boom arm folds or unfolds relative to a right side of the agricultural vehicle.
14. The agricultural vehicle of claim 13 , wherein each boom arm comprises a plurality of segments with an actuator of the plurality of actuators being configured to move each segment.
15. The agricultural vehicle of claim 14 , wherein the plurality of segments consists of three booms segments.
16. The agricultural vehicle of claim 10 , further comprising the controller being operable to unfold the boom to a predetermined position defined by a user, the predetermined position comprising a tilt and a height configured by the user.
17. A system for controlling an application boom mounted to an agricultural vehicle, comprising:
an application boom configured to deliver agricultural product to a field, the application boom having a plurality of actuators configured to fold and unfold the boom relative to the agricultural vehicle;
a brake pedal for braking the agricultural vehicle when the brake pedal is depressed; and
a controller in communication with the plurality of actuators and the brake pedal, the controller having a processor executing a program stored in a non-transient medium operable to:
receive a command to fold or unfold the boom relative to the agricultural vehicle;
determine if the brake pedal is depressed to within a threshold;
control the plurality of actuators to fold or unfold the boom relative to the agricultural vehicle in response to receiving the command while the brake pedal is depressed to within the threshold; and
cease to fold or unfold the boom relative to the agricultural vehicle in response to receiving the command while the brake pedal is not depressed to within the threshold.
