Abstract:
An air suspension control apparatus for a vehicle is disclosed. The apparatus includes a charge tank maintained at a first air pressure such that selective filling of the charge tank with compressed air is permitted. The arrangement is such that, in a first disposition of the tank air valve, the charge tank is maintained at a second air pressure which is less than the first air pressure. When the tank air valve is in a second disposition thereof, the charge tank is maintained at the first air pressure. In a third mode of operation of the air suspension control apparatus, the tank air valve is in the first disposition thereof and a ride height air valve is in the first setting thereof. The arrangement is such that the first pressure within the charge tank rapidly inflates the air spring from the third pressure to the second pressure so that driving of the vehicle is permitted.
