摘要： 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.

摘要： A vehicle-height control system including a tank, a compressor, an actuator, and a valve between the tank and the compressor. The valve is closed to a state of a pressure medium supplier to the compressor-pressure supply state when a tank pressure has reached a threshold in a tank-pressure supply state in which the tank pressure is supplied to the actuator. In the compressor-pressure supply state, the tank pressure is kept at the threshold, and a pressure in the actuator is greater than the tank pressure. The threshold makes it difficult for a pressure differential in the valve to become greater than a valve-opening pressure differential, making it difficult for the valve to be opened in the compressor-pressure supply state. This system enables good supply of a pressure medium from the compressor to the actuator, avoiding a longer time for vehicle height control and achieving a shorter compressor operation time.
