Model-Based Design of Service-Oriented Architectures for Reliable Dynamic Reconfiguration 2020-01-1364
Service-oriented architectures (SOAs) are well-established solutions in the IT industry. Their use in the automotive domain is still on the way. Up to now, the automotive domain has taken advantage of service-oriented architectures only in the area of infotainment and not for systems with hard real-time requirements. However, applying SOA to such systems has just started but is missing suitable design and verification methodologies. In this context, we target to include the notion of model-based design to especially address fail-operational systems. As a result, a model-based approach for the development of fail-operational systems based on dynamic reconfiguration using a service-oriented architecture is illustrated. For the evaluation, we implement our approach based on an existing model-based tool and consider an example function in the form of an automatically controlled braking system. In conclusion, we propose to apply our approach to further case examples. The vehicles' physical boundaries for functions are already braking and in particular, with the introduction of dynamic reconfiguration via cloud services, novel application areas are coming up.
