Abstract

In accordance with an example embodiment, a method comprising determining a change in configuration of a mobile machine, and in response to determining the change in configuration, initiating adjustment of a pressure of at least one tire of the mobile machine is disclosed.

First claim

What is claimed is:

1. A method for use with a mobile machine having a frame movable between a transport configuration and a field-use configuration, a configuration sensor to determine the configuration of the mobile machine and a central tire inflation system operable to adjust a pressure of at least one tire of the mobile machine, the method comprising:
determining a change in configuration of a mobile machine; and
in response to determining the change in configuration, initiating operation of the central tire inflation system to adjust a pressure of the at least one tire of the mobile machine.

2. The method of claim 1 , wherein the adjustment of the pressure comprises changing the pressure from a first predetermined level to a second predetermined level, wherein the first and second predetermined levels are set by an operator of the mobile machine.

3. The method of claim 1 , wherein the adjustment of the pressure of the at least one tire of the mobile machine comprises increasing the pressure of the at least one tire of the mobile machine in response to determining that the configuration of the mobile machine has changed from the field-use configuration to the transport configuration.

4. The method of claim 1 , wherein the adjustment of the pressure of at the least one tire of the mobile machine comprises reducing the pressure of the at least one tire of the mobile machine in response to determining that the configuration of the mobile machine has changed from the transport configuration to the field-use configuration.

5. The method of claim 1 , wherein the determining the change in configuration of the mobile machine is based at least in part on an input received from an operator of the mobile machine.

6. An apparatus, comprising:
a mobile machine having a frame movable between a transport configuration and a field-use configuration; and
a central tire inflation system operable to adjust a pressure of at least one tire of the mobile machine, in response to a determination of a change in configuration of the mobile machine between the transport configuration and the field-use configuration.

7. The apparatus of claim 6 , wherein the central tire inflation system is operable to increase the pressure of the at least one tire of the mobile machine in response to a determination that the configuration of the mobile machine has changed from the field-use configuration to the transport configuration.

8. The apparatus of claim 6 , wherein the central tire inflation system is operable to reduce the pressure of the at least one tire of the mobile machine in response to a determination that the configuration of the mobile machine has changed from the transport configuration to the field-use configuration.

9. The apparatus of claim 6 , wherein the central tire inflation system is operable to initiate an increase in a pressure of at least one tire of an implement coupled to the mobile machine in response to initiation of a change in configuration of the implement from the field-use configuration to the transport configuration.

10. The apparatus of claim 9 , wherein the central tire inflation system is operable to initiate a reduction in a pressure of the at least one tire of the implement in response to the implement substantially reaching the field-use configuration from the transport configuration.

11. The apparatus of claim 6 , wherein the determination of the change in configuration of the mobile machine is based at least in part on an input received from an operator of the mobile machine.
