Modeling and Analysis of Advanced Automotive ECU Architectures at Early Design Stages Using EMF and Model Transformation

In the automotive industry active safety functions are deployed to better protect the passengers and vulnerable road users in case of an accident. To do so, advanced system architectures which enable an OEM to integrate this new functionality safely and efficiently have to be developed. In order to evaluate different possible concepts at an early stage in the development, model-based approaches are feasible. We propose a methodical approach to evaluate architecture concepts with regard to standard analysis methods as well as application specific evaluation techniques. We use UML to define the meta-model structure of the system architecture, model the instances of the meta-model using EMF and a generated graphical editor, and perform evaluation operations with the help of an MDE framework. The tool chain allows for an easy modeling of system models at early design stages and performing application specific analysis techniques. To validate the feasibility of the approach we apply real-time schedule simulation to two example models.
