Modeling of Conventional Vehicle in Modelica

Modelica is a modern language used to model physical systems. The language is object-oriented, non-causal1 and the models are mathematically described by differential algebraic equations. The characteristic of modelica language make it very suited to define model libraries with reusable components, model complex applications involving parts from several application domains, and many more useful facilities. InteDrive library was created for simulating automotive driving performance, fuel consumption and emissions. The library is yet under developed by Huazhong University of Science and Technology in modelica language. The aim of the library is to provide the user with an easy to use and highly replaceable set of vehicle component models, and predict the vehicle performance, especially fuel consumption for a given cycle. The main components of this library and their applications are introduced in this paper. The simulation was carried out by MWorks, which is a general modeling and simulation platform developed by Huazhong University of Science and Technology. The simulation results were compared with ADVISOR. The easy and fast modeling process shows that modelica is very useful for the modeling and simulation of vehicles
