SUSPENSION CONTROLLER FOR VEHICLE

PURPOSE:To stabilize the traveling on a road surface which is covered by water or has puddles by detecting the road surface state and controlling a suspension to an optimum state even on bad road surface. CONSTITUTION:A pair of electrodes 7a and 7b are installed in opposed state on the undersurface of a car body 3, and the oscillation frequency of an oscillator 8 is varied in accordance with the capacity variation in the case when water adheres between a pair of electrodes 7a and 7b due to the splashing of water, and this variation is detected by a detector 9, and the vibration damping force of an oil damper 6 is strongly controlled by an actuator 10 in correspondence with the detection, and the safety in traveling on the bad road is secured.
