  • Key terms: Hazard, Triggering Events, Safe State, and Unsafe State

SOTIF Methodology and Framework Structure

  • Phases of the SOTIF life cycle
  • Interconnection between hazard analysis and risk assessment (HARA)
  • Principles of controllability and situational awareness

Hazard Identification and Classification

  • Anticipated hazards in ADAS and automated driving applications
  • Application scenarios and instances of functional limitations
  • Triggering events observed in operational environments

Hazard Analysis and Risk Assessment (HARA)

  • Methods for detecting and evaluating risks
  • Mitigation strategies for unknown and foreseeable hazards
  • Selection of appropriate risk mitigation measures

Engineering and Implementation for SOTIF Compliance
