Vehicle suspension control system with high flow exhaust mechanization

A method for operating an air management system for a vehicle having a body and plurality of wheels, said method including:

• providing at least one air spring for interconnecting the body and one of the wheels;
• providing a compressor for filling the air spring;
• providing a central air line disposed between the air spring and the compressor and fluidly connected to the air spring and the compressor;
• providing at least one spring air line extending between the central air line and the air spring;
• providing at least one suspension valve disposed along the spring air line and moveable between an open position and a closed position, wherein the suspension valve allows air to pass between the air spring and the central air line while the suspension valve is in the open position, and wherein the suspension valve inhibits air from passing between the air spring and the central line while the suspension valve is in the closed position;
• providing at least one auxiliary air line extending between the spring air line and the central air line;
• providing at least one high flow exhaust valve disposed along the auxiliary air line and moveable between an open position and a closed positioned, wherein the high flow exhaust valve allows air to pass between the spring air line and the central air line when the high flow exhaust valve is positioned in the open position, and wherein the high flow exhaust valve inhibits air from passing between the spring air line and the central air line when the high flow exhaust valve is positioned in the closed position;
• providing at least one isolation check valve disposed in series with the high flow exhaust valve along the spring air line and allowing air to pass through the isolation check valve from the air spring to the central air line and preventing air the passing through the isolation check valve from the central air line to the air spring;
• and
• positioning the suspension valve in the open position and the high flow exhaust valve in the open position to allow air to pass from the air spring through the suspension valve and the high flow exhaust valve to the central air line at a faster rate than it would pass through the suspension valve alone.
