PURPOSE: An electronic control device of an air spring for a vehicle and a method thereof are provided to improve driving experience and stability by controlling the height of the air spring according to passengers and the traveling state. CONSTITUTION: An air tank(1) is connected to an air bag(21) of an air spring(2) by a tubular body(3), and air supply and discharge solenoid valves(4,5) are installed in the tubular body. A linear variable differential transducer(6) is installed in the air bag, and a control unit(7) is mounted between the transducer and solenoid valves. The control unit receives an output signal from the transducer, and outputs on-and-off signals to supply and discharge solenoid valves by comparing the output signal from the transducer with the reference value. Driving experience is improved with adjusting the height of the air spring precisely by supplying air to the air bag.
