Advances in Automotive System Modeling: EAST-ADL (Part 1)
For decades developers of automotive embedded systems have enjoyed the benefits of modeling. Models have not only served communication and gaining better understanding but are also used to prototype, analyze, simulate and test the developed systems. With dedicated generators it has also been possible to produce production-quality software code from the models. Typical cases of code generation are various control-engineering solutions and infotainment systems with HMIs.
is also connected to the network via the communication ports.

Part two will cover Behaviour description and analysis, Dependability modelling, and Mapping to existing software architecture.


About the authors

DeJiu Chen received his PhD degree in Mechanical Engineering with a research on embedded computer control systems from KTH. His research interests are on systems and software architecture, model-based engineering, dependability and self-adaptive embedded systems. He has been actively involved in several research projects, including NFCCPP, ATESST, DySCAS, ATESST2, and MAENAD. From 2007 to 2009, Dr. DeJiu Chen also worked for Enea Data AB, Sweden, as a senior technical instructor. He is currently an associate professor at KTH.

Lei Feng is currently an assistant professor at the Department of Machine Design, KTH Royal Institute of Technology, Sweden. He received his Ph.D. degree from the Department of Electrical and Computer Engineering, University of Toronto, Canada, and Master's and Bachelor’s degrees from the Department of Mechatronics, Xi’an Jiaotong University, China. His research interests include formal verification using model checking, supervisory control theory, discrete-event systems, and advanced control applications in automotive engineering. From 2009 to 2011, he was a research engineer at Volvo Technology AB in Gothenburg, Sweden.

Henrik Lönn has a PhD in Computer Engineering from Chalmers University of Technology, Sweden, with a research focus on safety-critical real-time systems. Currently at Volvo Group, Advanced Technology and Research, he has worked with prototypes, architecture modelling and communication aspects on vehicle electronic systems. He is also participating in national and international research collaborations on embedded systems development. Previous project involvement includes X-by-Wire, FIT, EAST-EEA, ATESST and TIMMO. He is currently coordinating the FP7 MAENAD project.

Juha-Pekka Tolvanen is the CEO of MetaCase. He has been involved in model-driven
