This paper presents the algorithm that controls height of intelligent air suspension system for vehicles. The air suspension system mainly controls the heights of four air springs with real time feedback control. However, when applying this kind of control strategy, a rough road condition or signal noise causes unstable control. To prevent this problem, a new control algorithm that separates height measurements from actuating in control method is proposed. First, a mathematical model of air spring was developed. An operating time of each valve for air springs can be calculated from this mathematical model, which is necessary to control height without real time feedback system. From the simulation results, average error of the valve operating time between mathematical model and Amesim model was about 5%. It can be validated to prevent the unstable leveling signal problem in driving cycle simulation.
