Abstract

A vehicle system for a vehicle includes a controller. The controller is configured to transmit a first control signal to a transmission device of the vehicle to engage a first mode of the transmission device, acquire information regarding a pressure of an inlet flow of water received by a pumping system of the vehicle, and transmit a second control signal to the transmission device to engage a second mode of the transmission device based on the information.

First claim

The invention claimed is:

1. A vehicle system for a vehicle, the vehicle system comprising:
a controller configured to:
transmit a first control signal to a transmission device of the vehicle to engage a first mode of the transmission device;
acquire information regarding a pressure of an inlet flow of water received by a pumping system of the vehicle; and
transmit a second control signal to the transmission device to engage a second mode of the transmission device based on the information.

2. The vehicle system of claim 1 , wherein the controller is configured transmit the second control signal to the transmission device at least in response to the information indicating that the inlet flow of water has a positive intake pressure.

3. The vehicle system of claim 2 , wherein the controller is configured maintain the transmission device in the first mode in response to the information indicating that the inlet flow of water does not have the positive intake pressure.

4. The vehicle system of claim 1 , wherein the information is first information, and wherein the controller is configured to:
receive second information regarding an engine speed of an engine coupled to the transmission device; and
transmit the second control signal to the transmission device based on the first information and the second information.

5. The vehicle system of claim 4 , wherein the controller is configured to transmit the second control signal to the transmission device in response to (i) the first information indicating that the inlet flow of water has a positive intake pressure and (ii) the engine speed being less than a speed threshold.

6. The vehicle system of claim 1 , wherein the first mode is a higher mode than the second mode.

7. The vehicle system of claim 1 , wherein the controller is configured to receive the information regarding the pressure of the inlet flow of water from at least one of a sensor or a user interface.

8. The vehicle system of claim 1 , wherein the controller is configured to:
determine a location of the vehicle; and
determine the information regarding the pressure of the inlet flow of water based on the location.

9. The vehicle system of claim 8 , wherein the controller is configured to store a plurality of locations, each of the plurality of locations having a water source configured to provide the inlet flow of water at a predefined pressure.

10. The vehicle system of claim 1 , wherein the controller is configured to transmit the first control signal in response to activation of pumping operation, wherein the first mode is a default pumping mode for the transmission device.

11. The vehicle system of claim 10 , wherein the controller is configured to activate the pumping operation in response to at least one of (i) the vehicle being within a threshold distance of a destination, (ii) the vehicle being stationary, or (iii) a parking brake of the vehicle being engaged.

12. The vehicle system of claim 10 , wherein the controller is configured to activate the pumping operation in response to (i) the vehicle being within a threshold distance of a destination and (ii) at least one of (a) the vehicle being stationary or (b) a parking brake of the vehicle being engaged.

13. The vehicle system of claim 10 , wherein the controller is configured to activate the pumping operation in response to receiving an activation command from a user interface.

14. The vehicle system of claim 1 , wherein the controller is configured to:
operate the pumping system in a first pumping mode such that the pumping system provides an outlet flow of water to an ambient environment at a first outlet pressure; and
operate the pumping system in a second pumping mode such that the pumping system provides the outlet flow of water to a second vehicle fluidly connected to the pumping system at a second outlet pressure that is different than the first outlet pressure.

15. The vehicle system of claim 1 , wherein the first mode provides a higher speed output and the second mode provides a lower speed output.

16. A vehicle system for a vehicle, the vehicle system comprising:
a pump system;
a pump driver coupled to the pump system; and
a controller configured to:
transmit a first control signal to the pump driver to engage a first mode of the pump driver;
acquire information regarding a pressure of an inlet flow of water received by the pump system; and
transmit a second control signal to the pump driver to engage a second mode of the pump driver based on the information.

17. The vehicle system of claim 16 , wherein the first mode provides a higher speed output and the second mode provides a lower speed output.

18. The vehicle system of claim 16 , wherein the controller is configured to transmit the first control signal in response to activation of pumping operation, wherein the first mode is a default pumping mode for the pump driver.

19. The vehicle system of claim 16 , wherein the pump driver includes a transmission device having gearing.

20. A non-transitory computer-readable medium having computer-executable instructions encoded therein, the instructions when executed by one or more processors cause the one or more processors to:
transmit a first control signal to a pump driver for a pumping system to engage a first mode of the pump driver;
acquire information regarding a pressure of an inlet flow of water received by the pumping system; and
transmit a second control signal to the pump driver to engage a second mode based on the information;
wherein the first mode provides a higher speed output and the second mode provides a lower speed output.
