Model-Based Resource Analysis and Synthesis of Service-Oriented Automotive Software Architectures

Automotive software architectures describe distributed functionality through an interplay of software components. One drawback of today's architectures is their strong integration into the onboard communication network based on predefined dependencies at design-time. To foster independence, theideaofservice-orientedarchitecture(SOA) providesasuitable prospect as network communication is established dynamically at run-time. Aim: We target to provide a model-based design methodology for analysing and synthesising hardware resources of automotive service-oriented architectures. Approach: For the approach, we apply the concepts of design space exploration and simulation to analyse and synthesise deployment configurations at an early stage of development. Result: We present an architecture candidate for an example function from the domain of automated driving. Based on corresponding simulation results, we gained insights about the feasibility to implement this candidate within our currently considered next E/E architecture generation. Conclusion:Theintroductionofservice-orientedarchitecturesstrictly requires early run-time assessments. In order to get there, the usage of models and model transformations depict reasonable ways by additionally accounting quality and development speed.
