Abstract

A tire pressure regulating system and method are provided. The system includes a manifold that provides a fluid flow path between a pressure switch and a valve. The valve can switch between an open state and a closed state. Air bleeds from the tire when the valve is in the open state. The pressure switch signals the valve to open and close according to the pressure inside the manifold that is supplied from air pressure inside the tire.

Claims

1. A method of regulating a pressure of a tire, the method comprising:

transmitting a pressure from an internal space of the tire to a manifold;

sensing with a pressure sensor a current pressure in the manifold;

opening a bleed valve after the current pressure exceeds a set point pressure for an opening delay time, wherein the bleed valve is in fluid communication with the manifold; and

closing the bleed valve after the set point pressure exceeds the current pressure for a closing delay time.

2. The method of claim 1 further comprising:

assigning the set point pressure based on an input from a user interface.

3. The method of claim 1 further comprising:

assigning the opening delay time based on an input from a user interface.

4. The method of claim 1 further comprising:

assigning the closing delay time based on an input from a user interface.

5. The method of claim 1, wherein the bleed valve is a solenoid valve.

6. The method of claim 1, wherein the manifold comprises an inlet chamber and an outlet chamber, wherein opening the bleed valve provides a flow path from the inlet chamber to the outlet chamber.

7. The method of claim 6, wherein closing the bleed valve blocks the flow path from the inlet chamber to the outlet chamber.
