Challenges of Integrating Model-Based Digital Twins for Vehicle Diagnosis

The integration of independently developed digital twins for automotive diagnosis in a service-oriented vehicle architecture into a complex systems-of-systems rises various challenges to be handled. These challenges have to be tackled in detail for each particular domain and technical system architecture. Current research lacks to discuss them for service-oriented vehicle architectures. Within the project AUTOtech.agil, we are developing a digital twin for automotive diagnosis. This paper describes the application scenario, discusses integration challenges in detail and identifies possible mitigation strategies for the challenges. This discussion allows us to identify areas where general mitigation techniques have yet to be found and to extract a concrete roadmap for the automotive diagnosis digital twins.
