Abstract
A tire management system includes a control valve and a check valve. A method for managing a tire includes: determining a pressure parameter value, determining an operational parameter for a valve based on the pressure parameter value, and controlling the valve based on the operational parameter.
Claims19
A system for managing pressure in a tire of a vehicle, comprising:
- a manifold defining a channel and configured to distribute compressed air from a compressed air source;
- an intake valve configured to control air flow from the compressed air source to the channel;
- an exhaust valve configured to control air flow from the channel to an exhaust port;
- a pressure sensor configured to monitor a tire pressure in the tire;
- an electronic control unit in functional communication with the intake valve, the exhaust valve, and the pressure sensor, the electronic control unit configured to:
- command the intake valve to alternate between an open and a closed configuration in a first pulsing pattern in response to the tire pressure falling below a first target pressure by a first predetermined amount;
- command the exhaust valve to an open configuration in response to the vehicle being in a key-off state;
- command the exhaust valve to alternate between the open configuration and a closed configuration in a second pulsing pattern in response to the tire pressure being above a second target pressure by a second predetermined amount.

A method for managing pressure in a tire of a vehicle, the method comprising:
- distributing, by a manifold defining a channel, compressed air from a compressed air source;
- selectively controlling, by an intake valve, air flow from the compressed air source to the manifold;
- selectively controlling, by an exhaust valve, air flow from the manifold to an exhaust port;
- monitoring, by a pressure sensor, a tire pressure in the tire;
- commanding, by an electronic control unit, the intake valve to alternate between an open and a closed configuration in a first pulsing pattern in response to the tire pressure falling below a first target pressure by a first predetermined amount;
- commanding, by the electronic control unit, the exhaust valve to an open configuration in response to the vehicle being in a key-off state;
- and
- commanding, by the electronic control unit, the exhaust valve to alternate between the open configuration and a closed configuration in a second pulsing pattern in response to the tire pressure being above a second target pressure by a second predetermined amount.
