PURPOSE:To perform car height adjustment quickly and correctly by providing the first and second threshold values, setting a car height adjustment area and a car height adjustment completion area, controlling via a signal added with a predetermined value to the car height in the adjustment area, and controlling via a signal subtracted with the predetermined value from the car height in the adjustment completion area. CONSTITUTION:The detected car height of a car height detector 15 is fed to a control device 20. The control device 20 processes it according to a predeter mined program and judges whether the detected car height is in a car height adjustment area set in the receding direction from a target car height from the first threshold value or in a car height adjustment completion area set on the approaching side to the target car height from the second threshold value which is smaller than the first threshold value. A predetermined value is added to the car height detected signal in the car height adjustment area and it is subtracted in the car height adjustment completion area to obtain a control signal, and car height adjusting actuator 4 and operations switching valves 12a-12j are controlled. According to this constitution, car height adjust ment can be performed correctly and quickly. |
