Central tire inflation system
First Claim
1. A processor for controlling operation of a central tire inflation system to change a pressure of a vehicle tire from an initial tire pressure to a target tire pressure, the processor being configured to determine an interim tire pressure in dependence on the target tire pressure, and wherein, in order to change the pressure of said tire from the initial tire pressure to the target tire pressure, the processor is configured:
- first, to control the central tire inflation system to inflate said tire from the initial tire pressure to the predetermined interim tire pressure, said interim tire pressure being higher than the target tire pressure for said tire; and
then, to control the central tire inflation system to deflate said tire from the interim tire pressure to the target tire pressure.

Abstract
A processor for controlling operation of a central tire inflation system (CTIS) to change a tire pressure of a tire of a vehicle is configured to control the CTIS to inflate or deflate the tire to a predetermined tire pressure which is above a target tire pressure for the tire. The processor then controls the CTIS to deflate the tire until the target tire pressure is reached. In this manner, a second tire inflation operation to achieve the target tire pressure in the tire can be avoided.

12. A central tire inflation system comprising an electronic control unit having a processor for controlling operation of the central tire inflation system to change a pressure of a vehicle tire from an initial tire pressure to a target tire pressure, the processor being configured to determine an interim tire pressure in dependence on the target tire pressure, and wherein, in order to change the pressure of said tire from the initial tire pressure to the target tire pressure, the processor is configured:
-
first, to control the central tire inflation system to inflate said tire from the initial tire pressure to the predetermined interim tire pressure, said interim tire pressure being higher than the target tire pressure for said tire; and then, to control the central tire inflation system to deflate said tire from the interim tire pressure to the target tire pressure. - View Dependent Claims (13, 14)

15. A method of changing a tire pressure of a tire of a vehicle from an initial tire pressure to a target tire pressure comprising determining an interim tire pressure in dependence on the target tire pressure, and wherein, in order to change the pressure of said tire to the target tire pressure from the initial tire pressure, the method comprises the steps of:
-
first, using a central tire inflation system, inflating said tire from the initial tire pressure to the predetermined interim tire pressure, said predetermined interim tire pressure being higher than the target tire pressure for said tire; and then, using the central tire inflation system, deflating said tire from the interim tire pressure to the target tire pressure. - View Dependent Claims (16, 17, 18, 19, 20)
