Querying Automotive System Models and Safety Artifacts: Tool Support and Case Study

The automotive domain has recently increased its reliance on model-based software development. Automotive models are often heterogeneous, large and interconnected through traceability links. When introducing safety-related artifacts, such as Hazard Analysis, fault tree analysis (FTA), failure modes and effects analysis (FMEA) and safety cases, querying these collections of system models and safety artifacts becomes a complex activity. In this paper, we define generic requirements for querying megamodels and demonstrate how to run queries in our Model Management INTeractive ( MMINT ) framework using the Viatra query engine. We apply our querying approach to a vehicle’s Lane Management System case study through the process of its creation and maintenance, perform a comparison with an Object Constraint Language (OCL)-based approach and show how queries can help achieve compliance with the ISO 26262 standard.
