Abstract

A method includes identifying a number of actuators used to release a material, where the identified number of actuators is less than a total number of actuators. The method also includes identifying a simulated speed of a vehicle based on the identified number of actuators. The method further includes controlling an amount of material provided to the actuators based on the simulated speed of the vehicle. The method could also include identifying an extent to which the identified number of actuators are opened. Here, identifying the simulated speed of the vehicle could include identifying the simulated speed of the vehicle based on the extent to which the identified number of actuators are opened.

Claims

1. A method comprising:

controlling an amount of a material provided to actuators on a vehicle using at least one processing device, wherein controlling the amount of material comprises;

identifying a number of actuators used to release the material, the identified number of actuators less than a total number of actuators;

identifying a simulated speed of the vehicle based on the identified number of actuators; and

controlling the amount of material provided to the actuators based on the simulated speed of the vehicle.

2. The method of claim 1, further comprising:

identifying an extent to which the identified number of actuators are opened;

wherein identifying the simulated speed of the vehicle comprises identifying the simulated speed of the vehicle based on the extent to which the identified number of actuators are opened.

3. The method of claim 1, wherein identifying the simulated speed of the vehicle comprises:

identifying an actual speed of the vehicle; and

altering the actual speed of the vehicle based on the number of actuators used to release the material.

4. The method of claim 3, wherein identifying the actual speed of the vehicle comprises using a radar gun or GPS receiver.

5. The method of claim 3, wherein altering the actual speed of the vehicle comprises reducing the actual speed of the vehicle based on the number of actuators that are closed.

6. The method of claim 1, wherein controlling the amount of material provided to the actuators comprises providing the simulated speed of the vehicle to a pump controller, the pump controller using the simulated speed to control a pump.

7. The method of claim 1, wherein the actuators are carried by multiple booms on the vehicle.

8. The method of claim 1, wherein the material comprises at least one of:

seeds, plants, fertilizer, pesticide, weed killer, and water.

9. The method of claim 1, wherein the material comprises paint.

10. An apparatus comprising:

a controller configured to;

identify a number of actuators used to release a material, the identified number of actuators less than a total number of actuators; and

identify a simulated speed of a vehicle based on the identified number of actuators; and

an interface configured to output the simulated speed for controlling an amount of material provided to the actuators.

11. The apparatus of claim 10, wherein:

the controller is further configured to identify an extent to which the identified number of actuators are opened; and

the controller is configured to identify the simulated speed of the vehicle based on the extent to which the identified number of actuators are opened.

12. The apparatus of claim 10, wherein the controller is configured to identify the speed of the vehicle by:

identifying an actual speed of the vehicle; and

altering the actual speed of the vehicle based on the number of actuators used to release the material.

13. The apparatus of claim 12, wherein the controller is configured to identify the actual speed of the vehicle using a radar gun or a GPS receiver.

14. The apparatus of claim 12, wherein the controller is configured to alter the actual speed of the vehicle by reducing the actual speed of the vehicle based on the number of actuators that are closed.
