A control method of the air suspension leveling system is provided to control the height of the vehicles as the pulse width modulation duty is controlled. A control method of the air suspension leveling system comprises following steps: a step that determines whether the battery voltage is over the setting voltage or not(S105); a step for determining the peak pulse width modulation(PWM) time the battery voltage is the setting voltage or greater(S115); a step that determines whether the reversing/outside air valve is opened or not after setting up PWM duty completely(S120); a step for changing PWM duty in 100% to the hold PWM duty(S125). |
