A Process to Design and Master the Global Vehicle Electronic System Architecture

The introduction of the electronic sub-systems in the automotive vehicles and their tight level of interactions have led to an ever-increasing complexity of the embedded global electronic system. In addition to this complexity, the system architect has to deal with diversity of automotive products and to favor the reusability, while being constrained by the difference of visibility he has on each sub-system. Thus, managing the global vehicle electronic system appears to be very hard and necessitates adapted design methods and tools. Nevertheless, it eases the insertion of innovations in the vehicle and permits to differentiate products and adapt them to each customer's needs.

This article presents a design method for electronic system architecture - called CAROSSE - that ensures modularity and reactivity and promotes dependability studies and system-level validation. It takes advantage of heterogeneous multi-agent system techniques and modeling techniques in queuing system formalism.
