About this paper
Till Menzel, Gerrit Bagschik, Markus Maurer
To reconcile conflicting requirements for scenario representation in automated vehicle development, the paper proposes a structured framework with three abstraction levels – functional, logical, and concrete – to align with ISO 26262 phases and ensure traceability from safety goals to test cases.
Key insights
- Different phases of the ISO 26262 standard impose fundamentally conflicting demands on scenario representation, requiring both abstract, human-understandable descriptions and precise, machine-readable concrete values.
- A single, unified scenario representation cannot adequately fulfill all diverse requirements simultaneously across the entire development lifecycle.
- A layered abstraction model for scenarios provides a structured and traceable means to bridge the gap between abstract functional safety concepts and concrete test validation activities.
