On the Nature of Automotive Service Architectures

Context: Current trends in the automotive industry like automated driving, machine intelligence, and digitisation introduce more and more complex functions and their interplay in in-vehicle architectures. To cope with this complexity, car makers are introducing particularly tailored service-oriented architectures. Aim: We aim at developing a formal and methodological approach to model and structure automotive service architectures. Method: We present a formal model to specify and group automotive service-oriented architectures following a classification scheme. Furthermore, a well-defined property model is introduced facilitating the specification and verification of deployment and run-time requirements. The approach is illustrated using a realistic case example. Conclusion: The presented approach works well for the used case example but needs to be further evaluated in depth in the future. However, we strongly believe that the framework is promising and will receive further attention in future work.
