To ensure the safety of the intended functionality(SOTIF)in complex systems such as auton-omous driving,a SOTIF hazard analysis method based on failure mode and effect analysis(FMEA)was proposed.The method focused on functional insufficiencies in autonomous driving systems.From the perspective of functional concepts with measurable attributes,a detailed definition of functional in-suf-ficiencies was given,and the existing failure mode classification was refined.By establishing the con-nection between failure modes and functional insufficiencies,the application of FMEA in SOTIF hazard analysis was enhanced.The applicability of the extended AIAG&VDA failure mode classifi-cation to SOTIF issues and the advantages of the proposed method were demonstrated through a case study of an adaptive cruise control system.
