    • PROBLEM TO BE SOLVED: To provide a vehicle height control system having electronic system performance, while maintaining a low cost of a conventional mechanical system.
      SOLUTION: The system for controlling a distance between an axle and a vehicle frame, comprises: a sensor detecting a distance between the axle and the vehicle frame and generating a signal indicating the distance; a housing having a wall part defining a chamber which includes an inlet connected to a compressed air source, an operation port connected to an airbag, and an exhaust port connected to the atmosphere; a movable plate having a side part sealable with respect to a wall part by compression air supplied to the chamber; and a motor selectively moving the plate between a filling position where the operation port is connected to the inlet and a discharge position where the operation port is connected with the exhaust port, in a first rotational direction and in a second rotational direction opposite to the first rotational direction to selectively control the distance between the axle and the vehicle frame based on the signal.
