Modern powertrains increasingly include mechatronic components. Moreover, the correlation with vehicle dynamics and comfort is significant for powertrain development. Therefore, a holistic i.e. multiphysics appraoch is essential for the dynamic analysis in the design process. Hence, the multidisciplinary object oriented modelling language Modelica provides an ideal basis for simulations. This article describes both the basics and some application examples of powertrain modelling using the Modelica "PowerTrain" library. Amongst others, it comprises task-specific driver models, efficiency considerations, and 3D effects such as gyroscopic phenomena. Finally, results of some powertrain application example simulations will be shown.
