  • Publication number: 20170259639
    Abstract: A vehicle-height control system includes: a vehicle-height control actuator; a pressure-medium supply and discharge device configured to supply and discharge a pressure medium; and a vehicle height controller configured to control a vehicle height by controlling the pressure-medium supply and discharge device. The pressure-medium supply and discharge device includes a compressor and a tank configured to contain a pressure medium supplied from the compressor. The vehicle height controller includes a down controller configured to operate the compressor to discharge and supply the pressure medium from the vehicle-height control actuator to the tank to lower the vehicle height when a tank pressure is less than a set pressure. The down controller is configured to discharge the pressure medium from the vehicle-height control actuator to an outside to lower the vehicle height when the tank pressure is greater than or equal to the set pressure.
