Abstract
An active suspension system for vehicles, particularly motor vehicles, has active supporting assemblies which are arranged between the vehicle body and the vehicle wheels. Each of the assemblies includes a passive spring as well as a lift-adjustable control unit arranged in series thereto. The supporting assemblies are controlled as a function of body accelerations of the vehicle, and low-frequency and higher-frequency fractions of body accelerations, which are taken into account differently. As a result, the vehicle follows the road profile comparatively directly while the comfort is good.
