A vehicle height control system includes a fluid feeder and a vehicle height control unit. The vehicle height control unit includes a communication control unit. In a first communication state, a high-pressure source and a common passage are made to communicate with each other via the first passage and the second passage. In a second communication state, the first passage is shut off and the high-pressure source and the common passage are made to communicate with each other via the second passage. The communication control unit selects one from among the plurality of communication states based on at least one of a content of a start condition, a target vehicle height of a height increasing control and a number of wheels to be controlled in the height increasing control, when the start condition of the height increasing control is satisfied.

Vehicle height control system

A vehicle-height control system is configured to control a vehicle height for a wheel. The vehicle-height control system includes: a vehicle-height control actuator provided so as to correspond to the wheel; a pressure-medium supply and discharge device configured to supply and discharge a pressure medium to and from the vehicle-height control actuator; and a vehicle height controller configured to control the vehicle height for the wheel by controlling the pressure-medium supply and discharge device based on an inside temperature and an outside-air temperature to control at least one of supply and discharge of the pressure medium to and from the vehicle-height control actuator. The inside temperature is a temperature in the vehicle-height control system.

A vehicle-height adjustment system includes: a vehicle-height adjustment actuator provided so as to correspond to a wheel; and a pressure-medium supply and discharge device configured to supply and discharge a pressure medium to and from the vehicle-height adjustment actuator. The pressure-medium supply and discharge device includes a tank configured to store the pressure medium. The vehicle-height adjustment system includes a tank-pressure controller configured to control a tank pressure based on at least one of a vehicle height for the wheel and an inside temperature. The tank pressure is a pressure of the pressure medium stored in the tank, and the inside temperature is a temperature in the vehicle-height adjustment system.
