Claims

[Scope of Claim for Utility Model Registration] A vehicle height adjustment actuator installed between the vehicle body and each wheel that can individually increase or decrease the vehicle height, and detecting the vehicle height at the portion where each vehicle height adjustment actuator is attached to the vehicle body. flatness calculation means for calculating the flatness of the road surface on which each of the wheels touches the ground based on each vehicle height detected by the vehicle height detection means; a verticality calculation means for calculating the verticality of the vehicle body as a height from the road surface based on each vehicle height; and when the road surface is determined to be flat by the flatness calculation means, the vehicle height detection means; The vehicle height is adjusted by controlling the corresponding vehicle height adjustment actuator based on the detected vehicle height, and when the road surface is determined to be uneven by the flatness calculation means, the vehicle height is adjusted according to the calculated verticality of the vehicle body. A vehicle height adjustment device comprising: a control means for controlling an adjustment actuator to adjust the verticality of a vehicle body to around a predetermined value.
