A shock absorber system (20), including: a hydraulic shock absorber (22) configured to generate a damping force with respect to a relative movement of a sprung portion and an unsprung portion; a damping-force changer (24) configured to change the damping force; and a controller (26) configured to determine a damping-force index and to control the damping-force changer, wherein the controller is configured to determine, as the index, a required application force to be applied to the sprung portion for damping its movement in an up-down direction, according to a determination rule in which the required application force has the same direction as a direction of a speed of the sprung portion in the up-down direction when the sprung speed is relatively small and acceleration of the sprung portion in the up-down direction is relatively large in a situation in which the direction of the speed and a direction of the acceleration are mutually different.
