Modelica based modeling of automotive transmission

We propose an approach for modeling automotive transmission system using Modelica language. This approach includes dynamic models of clutch and synchronizer, and definition of a system structure for vehicle modeling. This approach enables building of detailed models of a complicated system more easily, and reusing models for different projects. A hybrid transmission is constructed using the approach proposed, and is integrated into the structurized vehicle model. This hybrid vehicle is validated in a virtual NEDC experiment.
