The invention provides a shock absorber system capable of effectively damping vibration of a suspension upper part. In a system capable of changing the damping force of a hydraulic shock absorber, as an index for changing the damping force, necessary suspension acting force, which is the force to be acted on a suspension upper part for damping the vertical motion of the suspension upper part, is used. The necessary suspension acting force is determined on the basis of such a determination rule that the necessary suspension acting force becomes the force in the same direction with the direction of a suspension velocity v, when the suspension velocity v is relatively small and a suspension acceleration [alpha] is relatively large in the case where the direction of the suspension velocity v and the direction of the suspension acceleration [alpha] are different from each other, namely in "the same direction region of suspension velocity and acting force".
