Abstract
A method of verifying the integrity of a valve in service in a tire pressure management system is disclosed. The method of verifying valve integrity of a valve interposed between a tire and conduit assemblies for conducting fluid to and/or from the tire in a tire maintenance system includes closing the valve for prohibiting fluid flow into the conduit assemblies in fluid communication with the valve and monitoring the pressure of fluid in the conduit assemblies in fluid communication with the valve for ascertaining a pressure increase therein.

13. A tire pressure management system, comprising:
-
a conduit conducting fluid to and from a tire;
a wheel valve disposed between said conduit and said tire;
a sensor in fluid communication with said conduit and generating a fluid pressure signal indicative of fluid pressure in said conduit; and
,an electronic control unit configured to urge said wheel valve to a closed position and to subsequently determine whether said wheel valve has failed by comparing said fluid pressure signal to a fist predetermined condition indicative of an increase in fluid pressure in said conduit. - View Dependent Claims (14, 15, 16, 17, 18)

19. A tire pressure management system, comprising:
-
a conduit conducting fluid to and from a tire;
a first control valve coupled to said conduit and movable between a first position permitting fluid communication between a fluid source and said conduit and a second position prohibiting fluid communication between said fluid source and said conduit;
a second control valve coupled to said conduit and movable between a first position permitting fluid communication between said conduit and atmosphere and a second position prohibiting fluid communication between said conduit and atmosphere;
a wheel valve disposed between said conduit and said tire;
a sensor in fluid communication with said conduit and generating a fluid pressure signal indicative of fluid pressure in said conduit; and
,an electronic control unit configured to move said second control valve to said first position for said second control valve to thereby vent said conduit and urge said wheel valve to a closed position and to subsequently determine whether said wheel valve has failed by comparing said fluid pressure signal to a fist predetermined condition indicative of an increase in fluid pressure in said conduit. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
