シヨン制御装置。[Scope of Claim for Utility Model Registration] A shock absorber that is interposed between the sprung mass and the unsprung mass of a vehicle and has an electric motor that can switch the damping force between hard and soft sides, and a relative between the sprung mass and the unsprung mass of the vehicle. A suspension control device comprising: a relative vibration state detection means for detecting a signal corresponding to a vibration state; and a damping force adjustment means for adjusting the damping force of the shock absorber based on the detection signal of the relative vibration state detection means. a vibration state determining means for determining whether or not the absolute value of the detection signal of the relative vibration state detecting means is larger than a first reference value; If it is determined that the absolute value of the detection signal is a vibration convergence state in which the absolute value of the detection signal continues to be smaller than the second reference value for a predetermined time with respect to a second reference value that is smaller than the first reference value. A vibration convergence determining means for determining whether or not the electric motor is in a vibration convergence state, and an initialization command means for issuing an initialization command for the rotational position of the electric motor when the vibration convergence determination means determines that the vibration convergence state is present. A suspension control device featuring:
