Advancing MBSE for ADAS/AD: Automated Scenario Generation

This paper explores the integration of model-based systems engineering (MBSE) and scenario-based engineering (SE) approaches in the development of advanced driver assistance systems (ADAS) and automated driving (AD). The increasing complexity of automotive systems necessitates efficient system design and validation processes. MBSE provides a framework for capturing system functionality and managing complexity, while SE focuses on testing and analyzing system features across various scenarios. By combining these approaches, system development efforts can be streamlined, leading to more efficient project management. This paper reviews existing literature on MBSE and SE in the context of ADAS development and highlights the potential benefits of their integration. An MBSE workflow is introduced where the key focus is on the behavioral aspects of the system. Additionally, a scenario generation pipeline which constitutes scenario databases is proposed to ensure comprehensive testing of system requirements. Results show that with automated scenario generation, the target vehicle cut-out scenario is successfully realized and simulated based on the formally described system behavior as part of the MBSE model.
