Abstract

PURPOSE:To enable the car-height to be adjusted automatically according to the condition of bad or flat road by constituting a suspension apparatus so as to permit transition to the high car-height side when the number of times in which the car-height detected by a photocell type height detector is outside a prescribed range is integrated and the integrated value is above a certain value. CONSTITUTION:The detection signal of each photosensor 101-103 of a height detector 100 is put into the car-height vibration detector 210 and the signal processor 220 of a car-height adjusting controller 200. In the car-height vibration detector 210, the continuous frequency in height variation is counted by counters CO4-CO6, and if the number of counts in a fixed time exceeds a prescribed value, the control signal D=H for high car-height is output into the signal processor 220, and in other cases, D=L is output. In the signal processor 220, the indicated height and the detected height are compared, and the energizing signal is output into an energizing controller 230, so as to change the detected car- height to the indicated car-height and thus a suspension apparatus 500 is controlled. Thus, the car-height can be adjusted automatically according to the condition of the bad or flat road.
