ンシヨン制御装置。 a fluid pressure cylinder that is interposed between the sprung mass and the unsprung mass of a vehicle and absorbs vibration input from the wheel side toward the vehicle body; a vibration input detection means that detects the vibration input; and a vibration input detection means in the pressure chamber of the fluid pressure cylinder. In an active suspension control device comprising a switching valve that controls fluid pressure and a control device that controls the switching valve based on a detection signal from the vibration input detection means, In order to absorb fluctuations by changing the volume, the pressure chamber is provided with a variable volume section whose volume can be changed according to the internal particle pressure, or a part of the pressure chamber is formed of an elastic member. This active suspension control device is characterized by:
