Summary:With the rapid development of the intelligence of autonomous vehicles, the safety risks faced by them are gradually increasing, as well as the accidents caused by their potential functional deficiency and performance limitation. The release of the Safety of the Intended Functionality (SOTIF) ISO 21448 adds a safeguard to the safety design of autonomous vehicles, which helps to reduce their potential functional deficiencies and trigger conditions and ensure their operation safety. In this paper, based on the perception layer of autonomous vehicles, the trigger conditions of safety of the intended functionality (SOTIF) were analyzed using the system-theoretic process analysis (STPA), including the camera, millimeter wave radar, and LIDAR in the perception layer, and the corresponding trigger conditions were given, which provides some practical reference for the intended function safety analysis and research of autonomous vehicles.
