PURPOSE: A leveling system of an air suspension vehicle is provided to easily secure installation space, facilitate mounting work, and use the system in common regardless of the kinds of vehicles. CONSTITUTION: A leveling system of an air suspension vehicle comprises a vehicle height-sensing mechanism(70) installed inside an air bag(11) of an air spring(10); a leveling valve(80) installed inside a lower bracket(13) of the air bag, to perform a passage conversion role of air lines by supplying compressed air of an air tank to the inside of the air bag or emitting the air of the inside of the air bag to the atmosphere; and an ECU(Electronic Control Unit,90) installed inside the lower bracket. The ECU receives signals for descending and ascending a frame(20) from the vehicle height-sensing mechanism, and operates the leveling valve by applying operating voltage of a battery to a supply solenoid of the leveling valve, in a descending signal, and applying voltage of the battery to an exhaust solenoid, in an ascending signal. Thus, freedom of design is improved and mounting work is facilitated.
