ブソーバ制御装置。 A variable damping force shock absorber which is interposed between a sprung mass and an unsprung mass of a vehicle and whose damping force can be changed by inputting a control signal, and a relative displacement detection signal obtained by detecting the relative displacement between the sprung mass and the sprung mass. a direction determination circuit that determines the direction of relative displacement with respect to the neutral position based on the relative displacement detection signal; and a direction determination circuit that outputs the control signal based on the determination result of the direction determination circuit and the relative displacement detection signal. When the relative displacement changes in the direction away from the neutral position, the damping force of the variable damping force shock absorber is softened, and when the relative displacement changes in the direction approaching the neutral position, the damping force of the variable damping force shock absorber is softened. A shock absorber control device comprising: a damping force control circuit that hardens the damping force control circuit; The shock absorber is characterized in that it has a delay circuit that delays the timing of switching from hard to soft by a predetermined time when the value of the unsprung component is below a predetermined value and the value of the relative displacement detection signal is above a predetermined value. Control device.
