ABSTRACT:
Provided is an electronic controlled air suspension system consuming less energy in preparing air in the high pressure reserve tank and low pressure reserve tank. Until the total sum of pressures of high pressure reserve tank and low pressure reserve tank reaches a predetermined first value, the pressure in the low pressure reserve tank is preferably controlled. After that, air in the low pressure reserve tank is supplied to the high pressure reserve tank until the pressure in the high pressure reserve tank reaches a desired value. In another feature of the invention, air is rapidly charged to the high pressure reserve tank regardless of the above procedure when a rapid charging to the reserve tanks are needed. This ensures continuous operations of rapid vehicle attitude control.
