自動運転モビリティにおける「未知の危険」シナリオへの対処
ハードウェア故障を対象とするISO 26262と異なり、ISO 21448 SOTIFは故障のないシステムにおける機能的限界や環境要因による危険を対象とします。SelfDrivingSim は照明条件や幾何学的遮蔽を系統的に変異させ、アルゴリズムの破綻境界をあぶり出します。
Core Engineering Areas
- ISO 21448 SOTIF Verification — Executing automated test matrices that deliberately probe trigger conditions for performance limitations in perception sensors and motion planners.
- Combinatorial Boundary Fuzzing — Applying genetic algorithms and Bayesian optimization to discover the exact combinations of cut-in distances and decelerations that defeat AEB controllers.
- OpenSCENARIO 2.0 Execution Runtime — Executing declarative, intent-based driving scenarios with dynamic actors capable of reactive behavior based on the autonomous vehicle's actions.
