| dc.description.abstract | This work has been accepted at the 23rd International Conference on Fundamental Approaches to Software Engineering, held as part of the European Joint Conferences on Theory and Practice of Software, ETAPS 2020. The increase of complexity in modeling cyber-physical systems poses a challenge for formally ensuring their functional correctness. Lack of expert knowledge and scalability are two limiting factors that prohibit a seamless integration into today's software engineering processes. To address this challenge, we propose to adopt and formalize the notion of skill graphs, an abstract and easy-to-use modeling notion for representing automated vehicle driving maneuvers. For formally verifying that skill graphs are well-formed and comply with a given set of safety requirements, we incorporate hybrid programs into our formalization. Hybrid programs constitute a program notion for cyber-physical systems on the basis of differential dynamic logic, which enables deductive and compositional verification following the idea of Hoare-style reasoning. That is, simpler verified skill graphs can be combined to exhibit complex maneuvers while validity is retained (i.e., without the need of re-verification). To showcase the benefits of our theoretical considerations, we implemented our framework in an open-source tool named Skeditor and conducted a case study exhibiting an automatic vehicle follow mode. | en |
