HARA systematically identifies vehicle-level hazards and determines Automotive Safety Integrity Levels (ASIL A-D) through structured assessment of Severity, Exposure, and Controllability. The process covers operational situation analysis, hazard event formulation, risk parameter classification according to ISO 26262-3 tables, and ASIL derivation. Includes practical techniques for ensuring consistency, managing edge cases, establishing traceability to safety goals, and documenting assumptions.
HARA (Hazard Analysis and Risk Assessment)
Identify hazards, derive operational situations, and assess Severity, Exposure, and Controllability to assign ASIL. Includes categorization tips, consistency checks, and traceability to goals.
