Research on SOTIF of automatic driving system

With the development and popularization of autonomous driving technology, its safety issues have attracted more and more attention from the public. The performance limitations and insufficient functions of the perception system and execution system of autonomous driving, the algorithm defects of perception algorithms, the decision-making algorithms, the control algorithms, special weather and traffic, and the safety risks caused by reasonably foreseeable misuse of personnel, are the biggest challenges in the development and industrialization of autonomous vehicles. Aiming at solving these challenges, the concept of Safety of The Intended Functionality (SOTIF) of autonomous driving is proposed in this work. The conceptual definition and research status of the SOTIF of the automatic driving system were introduced, the main challenges and the system analysis methods of the SOTIF of the automatic driving system were analyzed, and research outlooks were put forward.
