Abstract: A vehicle height adjustment device includes an actuator, a detector, and a controller. The actuator is driven when supplied with a current and is configured to change a relative position of a body of a vehicle relative to an axle of a wheel of the vehicle. The detector is configured to detect the relative position. The controller is configured to control the current supplied to the actuator to make the relative position a target value so as to adjust a vehicle height of the body. When a detection value of the detector is smaller than the target value of the relative position, the controller is configured to alternately supply an increase current and a maintenance current to the actuator. The increase current increases the relative position to increase the vehicle height. The maintenance current maintains the relative position to maintain the vehicle height.

Abstract: A vehicle height adjustment device includes a spring. An adjustor includes an accommodation chamber accommodating a fluid to adjust a length of the spring based on the fluid amount in the accommodation chamber. A storage chamber stores the fluid. A pump includes a cylinder that takes in the fluid in the storage chamber when a distance between a vehicle body and a vehicle wheel increases, and that discharges the fluid when the distance decreases. A passage switch unit switches among a first state in which the fluid discharged from the pump is guided into the accommodation chamber to increase the fluid amount in the accommodation chamber, a second state in which the fluid in the accommodation chamber is guided into the storage chamber to decrease the fluid amount, and a third state in which the fluid amount is maintained. Without electric current supply, the third state is maintained.
