This paper presents the results obtained on the basis of the mechatronic model of a passenger car. In order to minimize the induced mechanical vibrations during drive event on a coarse road surface, a modification of the structure of the vehicle suspension has been applied. The proposed modification introduces additional active damping element, which task is to reduce the vertical displacement of the vehicle body. In the real world such a target can be achieved by use of appropriate control units, which drive the electronic and hydraulic components of the suspension. Additionally, the phenomenological models of the passengers have been included into the computer simulation model. Keywords: modelling, mechatronics, vibroisolation, mechanical vibration. MODELOWANIE DYNAMIKI PIONOWEJ SAMOCHODU OSOBOWEGO W UJĘCIU MECHATRONICZNYM Streszczenie Niniejszy artykuł przedstawia wyniki badań modelowych uzyskane na podstawie mechatronicznego modelu samochodu osobowego. W celu minimalizacji drgań mechanicznych wzbudzanych podczas jazdy po nierównym podłożu zastosowano modyfikację konstrukcji zawieszenia samochodu. 1 Ford-Werke GmbH, Henry-Ford-Straße 1, 50735 Köln, Germany, Maildrop.
