Abstract
An apparatus for active control of body motions of a motor vehicle, to reduce undesired vehicle motion, to improve the rise and simultaneously adjust the level of the vehicle, while requiring very little energy overall, comprising three structural elements disposed in a parallel operative arrangement, namely an extremely soft compensation spring, which bears the majority of the static weight of the vehicle body; a final control element, the behavior of which is triggerable via an electronic control unit and which may be embodied pneumatically or hydraulically and in each case includes a spring element function that reacts in the manner of a substantially stiffer final control element spring; and as the third element, a semiactive damper, in which throttle valves for a tension and compression stage are triggered either in opposite directions or the same directions, depending upon which active or passive damping signals are to be processed.
