ABSTRACT
With the rapid development of intelligent connected vehicles and autonomous driving technology, the port logistics industry is seeking more advanced and effective solutions. Safety of the intended functionality (SOTIF) of unmanned port vehicles equipped with autonomous driving function has become a focus of attention in the industry. Based on the theoretical foundation of ISO 21448, this article focuses on the automatic obstacle avoidance function of port unmanned vehicles. By defining system hazards, determining system level constraints and initial system level safety requirements, establishing a system safety control structure, constructing scene elements under a hierarchical system, identifying unsafe control behaviors, and analyzing the reasons. The final determination of safety constraints leads to the expected functional safety requirements, providing theoretical and analytical basis for subsequent simulation and testing.
