A vehicle suspension includes a shock absorber whose damping coefficient is variable. A control device includes: a road surface input sensor that generates a first signal corresponding to a vertical movement of each wheel; a sprung mass behavior sensor that generates a second signal corresponding to a vertical movement of a vehicle body at a position of each wheel; and a control unit that controls the damping coefficient. The control unit performs: a normal control that sets the damping coefficient to a hard-side value with regard to a wheel where the second signal indicates occurrence of a sprung mass behavior exceeding a standard; and a rear wheel softening control that sets the damping coefficient regarding a rear wheel to a soft-side value lower than the hard-side value, when determining, based on the first signal, that a rear-wheel-rising-time-point when the rear wheel reaches a rising point on a road surface comes.
