Claims

[Scope of utility model registration request]

Vehicle height adjustment of a vehicle comprising: a vehicle height adjustment actuator interposed between a vehicle body and wheels so as to be able to adjust the vehicle height; and vehicle height adjustment means for driving the vehicle height adjustment actuator to adjust the vehicle height. The device includes a vehicle speed detector that outputs a detection signal according to the vehicle speed, a vehicle height detector that outputs the detection signal according to the vehicle height, and a foot brake that outputs the detection signal according to the operating state of the foot brake of the vehicle. a brake state detector; a parking brake state detector that outputs a detection signal according to the operational state of the parking brake of the vehicle; and a door/trunk state detector that outputs a detection signal according to the open/closed state of a door or trunk of the vehicle. Based on the detection signals of the vehicle speed detector, vehicle height detector, foot brake status detector, parking brake status detector, and door/trunk status detector, at least the vehicle remains closed with its doors or trunk closed. The vehicle height adjustment means prevents the vehicle height adjustment actuator from adjusting the vehicle height when a change in vehicle height occurs due to a change in the operating state of the foot brake and the parking brake while the vehicle is stopped. A vehicle height adjustment device comprising: a control means for controlling;
