PURPOSE:To hold car height in a stable state in the vicinity of a position in the center ''medium'' and prevent repeated action of urging and stopping adjustment of the car height, by continuously performing at least up-urging action of the car height up and down urging actions with suitable hysteresis even if the car height restores the position ''medium''. CONSTITUTION:A car height detector 100 detects car height to change from a ''medium'' state, as shown in the drawing, to a ''high'' or ''low'' state by such means that the end part of a light shielding plate 104, moving to interlock to the vertical displacement of a differential gear device through a link 20, is intruded into either a photosensor 101 or 102. Output of this car height detector 100 is fed to a car height adjustment controller 120, consisting of a signal processor 130 and urging controller 140, to control a relay 201 for a compressor driving motor or relief valve 300. At this time, said controller 120 is constituted in such a manner as to hold its preceding state for a prescribed period, even after a change corresponding to a stop of urging action for the driving line of a suspension device 400 to a car height decision area, and continuously perform urging action of said driving line. |
