An active suspension system, in particular for motor vehicles, is provided whose suspension or support units arranged between the sprung and the unsprung mass have, in each case, a passive, uncontrolled spring element and, arranged in series with the latter, a hydraulic displacer unit with controllable adjustment. The arrangement of displacement pick-ups, which reproduce the stroke position of the sprung mass relative to the unsprung mass and the stroke of the displacer unit, allows for carrying out a regulation of the current supporting forces by a required/actual value comparison which uses only the displacement measurements.
