The Scenario component focuses on managing scenarios critical for safety assurance, encompassing three key processes: creation, formatting, and storage.
- Scenario Creation involves generating scenarios based on data-driven or knowledge-driven approaches. Scenarios are derived using methodologies like StreetWise, which extracts real-world scenarios and statistics from driving data, or database like Safety Pool™, which leverage various scenario generation methods. These processes occur within individual SCDBs, reflecting database-specific requirements and use cases. While scenario creation is handled independently by SCDB providers, it is integral to the overarching safety assurance framework.
- Scenario Formatting structures scenarios into appropriate representations for effective communication and downstream testing. Multiple levels of abstraction are employed to cater to diverse stakeholders, ranging from human-readable functional and abstract-level scenarios to machine-readable logical and concrete-level scenarios. Common formats like ASAM OpenSCENARIO, OpenDRIVE, and BSI Flex 1889 ensure interoperability and standardization.
- Scenario Storage consolidates formatted scenarios within SCDBs, enabling seamless access and integration. The SUNRISE project introduces a Federated Layer to link multiple SCDBs, requiring database owners to adhere to shared formats and abstraction levels to connect. This federated approach ensures unified access while maintaining flexibility for individual database management.
Together, these processes enable a structured, standardized, and scalable approach to scenario management for CCAM system safety assurance.
