Abstract

PURPOSE:To have automatic adjustment of car height in compliance with the condition of road by setting a target value in accordance with oscillation in sensed car height. CONSTITUTION:Potentiometers 12-15 are furnished at the front and rear suspension devices 1-4 to sense the car height. The car height sensed off is placed into a car height control device 20 and micro-computers 231-233 control valves 7, 8 so that the target car height is attained. The car speed signal is obtained through car speed meter cable 28. LED display alleys 271, 272 give indication of the car height. The CPU 231 calculates the time system smoothed value for the sensed car heightto set a target value for the car height according to the oscillation in the smoothed value for the sensed car height. Because car height is determined according to oscillation, the car height is kept at the optimum always in compliance with the condition of the road.
