Abstract
A vehicle-height control system includes: a fluid supply and discharge device including a compressor device and a tank storing fluid pressurized by the compressor device; a vehicle-height control actuator corresponding to a wheel and connected to the fluid supply and discharge device; a vehicle height controller that controls a vehicle height for the wheel by controlling the fluid supply and discharge device to control supply and discharge of fluid to and from the vehicle-height control actuator; a tank pressure controller that controls a tank pressure; and a fluid supply controller that supplies the fluid to a low pressure portion by controlling the fluid supply and discharge device at start and/or termination of at least one of control executed by the vehicle height controller and control executed by the tank pressure controller. The low pressure portion is at least a portion of the fluid supply and discharge device.
