Analysis and Research on SOTIF of Typical L3 Autopilot System

With the increasing speed of automobile intelligence, the safety of the corresponding electrical and electronic system design is particularly critical. ISO, the international standardization organization, officially released the SOTIF standard in June 2022. It is imperative that the development of the Autopilot System conform to this standard, but there is a lack of complete SOTIF development practice cases in China. Based on the typical L3 automatic driving system HWP system, this paper analyzes the SOTIF hazard behavior, risk assessment, trigger conditions and function modification measures, and gives corresponding practical examples, which provide a practical reference for the SOTIF analysis and research of automatic driving vehicles.
