Abstract

The present invention provides a suspension control device with which the damping coefficient of the suspension can be easily adjusted on the basis of only the vertical vibration of a body of a vehicle, without measurement of the relative velocity or the relative displacement between the body and the wheel along the vertical direction. The absolute velocity of the body 1 is calculated on the basis of the detected signal of the acceleration sensor attached to the body 1, then the rotation angle .theta. of the movable plate is calculated on the basis of the absolute velocity, and the movable plate is rotated in the predetermined direction by the rotation angle .theta.. Accordingly, the damping coefficient is adjusted so that the coefficient in the extension of the shock absorber becomes larger and the coefficient in the compression of the shock absorber becomes smaller, or so that the damping coefficient in the extension becomes smaller and the coefficient in the compression becomes larger.
