Abstract
A failure tolerant tire inflation system for supplying pressurized air from an onboard source to the vehicle tires in the event of a pressure drop in one or more of the tires below a predetermined level. The system includes a tire inflation valve communicable with the source of pressurized air, a tire selector valve assembly for selectively communicating air from the tire inflation valve with the vehicle tires, a plurality of valve assemblies each communicating with at least one tire and selectively communicating with the tire selector valve assembly. A controller selectively activates and deactivates the tire inflation valve and valve assemblies to sequentially check the pressure in the tires and direct air to any underinflated tire. A transducer is provided for detecting the tire pressure levels upon the opening of the valve assembly communicating with that tire and communicating the underinflated condition to the controller.
