Abstract
A semi-active suspension control system comprises exclusively chassis acceleration sensors (S.sub.1 to S.sub.3) as sensors (1) for obtaining the information for the damping force control. The output signals of these sensors are analyzed in a filter (3), the transmission behavior of which is in linear approximation to the transmission behavior of a discrete Kalman filter, when concentrating on the frequency range between the natural chassis frequency and the natural wheel frequency.
