Abstract
A damping force control apparatus for a suspension is applied to a damper whose damping force can be set based on a damping force control value and controls the damping force control value. The damper is attached to a support portion with a buffer member interposed between the support portion of a vehicle body and a cylinder of the damper. The apparatus includes: a displacement related quantity estimation device estimating relative displacement of a vehicle wheel and a relative speed of the vehicle wheel with respect to the vehicle body as estimated relative displacement and an estimated relative speed; and a damping force control value calculation device determining the damping force control value so as to suppress vibration of the vehicle body based on state variables provided from the vehicle body and the estimated relative speed.
