摘要:
A method for measuring the pressure of fluid in the wet tank (32) of a central tire inflation system (10) prior to initiating a tire pressure check sequence in order to ensure an accurate tire pressure reading by waiting for a sufficient wet tank pressure. To measure wet tank pressure, the wet tank (32) is isolated from the atmosphere and from a distribution manifold (55). Pressure is measured with an existing pressure transducer (44). Once wet tank pressure is sufficient, a normal tire pressure check sequence is allowed to begin.

An apparatus for and a method of sensing fluid pressure of a tire and the fluid supply of a tire pressure management system maintaining same, with a central sensor and which requires the control of only two valves. The apparatus for sensing fluid pressure of a tire and the fluid supply of a tire pressure management system maintaining same, includes a sensor disposed so as to be selectably in fluid communication with one or both of: a first valve, operable from an open position through a closed position, for respectively promoting and prohibiting fluid flow from the fluid supply, and a second valve, operable from an open position through a closed position, for respectively promoting and prohibiting fluid flow to or from the tire. The method of sensing fluid pressure of a tire and the fluid supply of a tire pressure management system maintaining same includes disposing a sensor so as to be selectably in fluid communication with one or both of: a first valve, operable from an open position through a closed position, for respectively promoting and prohibiting fluid flow through a supply passage from the fluid supply, and a second valve, operable from an open position through a closed position, for respectively promoting and prohibiting fluid flow to or from the tire.

摘要:
A tire inflation method is disclosed for moving air through a fluid control circuit to at least one tire that is below a target pressure. The dynamic pressure of the moving air in the fluid control circuit is monitored. A pressure control valve in the fluid control circuit is cycled on and off to prevent the dynamic pressure from reaching a predetermined amount over the target pressure.

A method of inflating a tire, or vehicle tire, that minimizes the amount of time needed for same is disclosed. The method of inflating a tire with a tire pressure management system includes introducing continuous fluid flow of a fluid into the tire, ascertaining the dynamic pressure of the fluid during said introducing continuous fluid flow, terminating continuous fluid flow when the dynamic pressure exceeds or equals a predetermined amount, and introducing pulsed fluid flow of the fluid into the tire.

The present invention relates to a vehicle brake system, which has a brake reservoir, and utilizes a tire management system that is in communication with the brake reservoir and a vehicle operator. As a result of this configuration, the tire management system communicates brake reservoir pressure signals to the vehicle operator, so that the operator is made aware of any low pressure conditions, in the trailer, before trying to move the trailer.
摘要:
The present invention relates to an automatic inter-axle differential sensor configuration (i.e., location) and calibration method for a vehicle having a tandem drive axle. The method involves determining the speed of the vehicle, determining pulses per minute from each inter-axle differential sensor via the vehicle electronic control unit (ECU), where each of the inter-axle differential sensors are connected to an inter-axle differential gear, determining a location of each inter-axle differential sensor from each of the inter-axle differential sensor pulses per minute, and assigning a number of teeth to each of the inter-axle differential gears in calibrating each of the inter-axle differential sensors. The revolutions per minute for each of the inter-axle differential sensors may be utilized to lock the inter-axle differential during slippage of the vehicle, without human intervention.
