A method for control of a tire pressure management system (or central tire inflation system) is provided which enables active adaptation of control variables in the system in response to variations in air line volume. The air line volume in a conduit between an air source and a vehicle tire is determined. Subsequently, one or more values for control variables are adjusted in response to the air line volume and various parameters associated with the system are determined in response to the adjusted values of the control variables.

1. Field of the Invention
This invention relates to vehicle tire pressure management systems and, in particular, to a system and method for adapting control algorithms in vehicle tire pressure management systems.
2. Discussion of Related Art
FIG. 1 is a diagrammatic view illustrating a tire pressure management system for a vehicle in accordance with the present invention.
FIG. 2 is a sectional view of a conventional vehicle wheel assembly.
FIG. 3 is a block diagram illustrating several of the components of the system of FIG. 1.
Referring now to the drawings wherein like reference numerals are used to identify identical components in the various views, FIG. 1 illustrates a tire pressure management system 10 for a vehicle 12 (shown diagrammatically by a dotted line) in accordance with the present invention. In the illustrated embodiment, vehicle 12 comprises a tractor-trailer. It should be understood, however, that the inventive system may be used in connection with a wide variety of vehicles including automobiles.
Vehicle 12 may include a plurality of axles including a steer axle represented by dotted line 14, a tandem axle assembly having drive axles represented by dotted lines 16, 18 and another tandem axle assembly having trailer axles represented by dotted lines 20, 22. Referring to FIG. 2, each axle of vehicle 12, such as drive axle 16, may include wheels 24 affixed to wheel hubs 26 disposed at each outboard end of the axle and rotationally supported on the axle. Each wheel 24 of vehicle 12 may include one or more inflatable tires 28 mounted thereon.
Referring again to FIG. 1, a system 10 in accordance with the present invention will be described. System 10 is provided to monitor and control pressure within each tire 28 of vehicle 12. System 10 may include wheel valve assemblies 30, an air source 32, a vacuum source 34, an air control circuit 36, one or more load sensors 38, a speed sensor 40, a pressure sensor 42, an operator control device 44, and an electronic control unit (ECU) 46.
