Patent ID: 8849513

Claim:
A modular system for controlling a supply of pressurized air to a plurality of vehicle air suspension systems in response to an input from a vehicle driver, the system comprising: a first air control unit including a first housing with a plurality of first internal air passages defining a first manifold receiving the supply of pressurized air, wherein at least one of the first air passages is in fluid communication with a first selected one of the air suspension systems, a first air pressure sensor on the housing in communication with one of the first air passages generating an output representative of an air pressure achieved in the one of the first air passages, a plurality of first valves on the housing controlling a flow of the supply of pressurized air through the first air passages, and a first unit controller on the first housing operating the first valves in response to the output of the first pressure sensor and a first control signal generated externally of the first air control unit, the first unit controller further generating a first return signal based on the output of the first air pressure sensor; a first driver interface in communication with the first unit controller, the first driver interface generating the first control signal in response to the driver input and receiving the first return signal from the first unit controller, the first driver interface displaying information representative of the air pressure achieved in the one of the first air passage based on the first return signal; and a second air control unit including a second housing with a plurality of second internal air passages defining a second manifold receiving the supply of pressurized air, wherein at least one of the second air passages is in fluid communication with a second selected one of the air suspension systems, a second air pressure sensor on the housing in communication with one of the second air passages generating an output representative of an air pressure achieved in the one of the second air passages, a second valve on the housing controlling a flow of the supply of pressurized air through one of the second air passages, and a second unit controller operating the second valve in response to the control signal generated externally of the first air control unit and at least one of the output of the first pressure sensor and the output of the second pressure sensor, the second unit controller generating a second return signal based on the output of the second air pressure sensor, wherein the first driver interface receives the second return signal from the second unit controller, and the first driver interface displays information representative of the air pressure achieved in the one of the second air passages based on the second return signal.
