Service-based modeling of cyber-physical automotive systems: A classification of services
Abstract
Systems of systems such as Smart Ecosystems, Cyber-Physical Systems, and the Internet of Things support flexible collaborations among heterogeneous participants with open interfaces. To assure safety in all possible collaboration scenarios, we introduced in previous work the ConSerts approach. This approach assumes that system interactions are captured via required and provided services. Considering the interaction between vehicles and infrastructure, this fundamental assumption is problematic as there is no commonly accepted approach for modeling these future Car-to-X scenarios. Existing modeling approaches in the automotive domain consider the realization of the functionality of one vehicle and typically have a functional, dataflow-oriented character. In this paper, we will derive a classification for services in order to contribute to the definition of our required service-based modeling of cyber-physical automotive systems.
