A device and a method of estimating damper force and damper velocity in an active suspension system. First and second pressure sensors sense pressures of a rebound chamber and a compression chamber of a damper in the active suspension system. A controller calculates damper force using the pressures and effective hydraulic pressure areas of the rebound chamber and the compression chamber and calculating damper velocity using pressure-fluid rate characteristics of first to third valve sets and the pressures of the rebound chamber and the compression chamber such that a sum of fluid rates is zero in a node connected between any one of the first to third valve sets and the rebound chamber or the compression chamber, the first to third valve sets being connected between the rebound chamber and an accumulator, between the rebound chamber and the compression chamber, or between the compression chamber and the accumulator.
