“…By comparing the simulation results with the measured data from actual test-drives, it is evident that by considering the undercarriage contact a better coincidence between simulation and ride experiments is obtained. The following is mainly referring to results, recently published in [16].…”

Mechatronics as an interdisciplinary combination of domains of mechanical engineering, electrical engineering, electronics, and computer science has developed in industry and universities since the eighties of the last century, and it is meanwhile fully established in many technical areas. The main focus of the mechatronic approach is to extend and to complete the design process of mechanical and more general engineering systems by incorporating from the very beginning sensors and controllers -which includes also the required information processing -and thus being able to generate partly intelligent products. The components and modules of such systems originate from mechanical engineering, from electrical engineering or from other engineering domains. Methods for describing and designing these components and modules are based in the fields of applied mechanics, electrical engineering, system theory, control and automation theory, and information processing. In particular, in mechatronic systems like robots, manipulation systems, machine tools, or all kinds of vehicles, the multibody systems approach offers a powerful tool to model the mechanical properties of the system in an appropriate manner. In this paper, methodologies for the development of formalisms and software for modeling and simulation of multibody and mechatronic systems will be presented and illustrated by examples from automotive systems and robotics.

To raise the occupant's and vehicle's safety in of the rollover sensors activating the safety systems in the traffic, the automotive industry develops more and more case of an accident a large number of different rollover safety systems which should assist the driver and protect the maneuvers has to be analyzed. It should not be forgotten, occupants, respectively. For the development and the improvement of these systems, a large number of accident however tat the s ti ofhisue ie. to a'v e of scenarios have to be analyzed in respect of the influence of misfire ices where a thetvehiceseemstto er but such systems to the accident. Since the vehicle rollover is actually does not are as important to be nvesthgated. One of amongst the most dangerous accident and responsible or the standard accident scenarios is the embankment serious injuries or even fatal cases, this scenario has to be maneuver. investigated and analyzed for the development of so-called~~~~~--..vehlicle spec jf dt i]cuuc I] a rqiri passive safety systems, like airbags, belt pretensioners and lers frsal'o:s;s data m]tsurcnicins arc rcql1tCi and 1to riLs io ckVSYtIi urin,,! extreme MC LIC rollover bars, with the help of computer simulations. aalo Therefore, the vehicle dynamic has to be mapped.

Active safety systems assist the driver in critical situations. A popular example is the Electronic Vehicle dynamics Figure 1 Vehlle ynaicssimulations to support the controller development Stability Program (ESP), which stabilizes the car by braking wheels individually. The active safety systems are For the simulation of embankment maneuvers, the vehicle dedicated help to circumvent accidents before they occur. is preferably to be modeled as a multibody system. During Passive safety systems reduce the consequences of the vehicle dynamics simulation of sport cabriolets, very accidents for the occupants. The occupant restraint systems, special effects like e.g. the scrapping of the vehicle over the like airbags, belt pretensioners and rollover bars, protect the ground have to be considered as well due to the low ground occupants as far as possible against severe injuries.
