With the development of parts and systems for automated vehicles increases, the application of the SOTIF standard and ISO/TR 4804 standard is expanding. In particular, the ISO 26262-based methods of dealing with system internal failures cannot analyze risks arising from causes other than failures, such as performance limitations and driver misuse. Therefore, in addition to the previously applied safety analysis, it is necessary to apply STPA analysis that effectively supports analysis from this perspective. The characteristic of STPA is that it not only analyzes the inside of the system, but also analyzes unsafe control action that occurs in the interaction between the controller and the controlled process. We analyze which UCAs lead to hazards and under which circumstances they occur. Afterwards, a detailed cause factor analysis step is performed. The advantage of STPA from a SOTIF perspective is that context is derived when identifying UCAs. This allows an explicit analysis of which control actions can lead to hazards and under what circumstances. Therefore, it supports identifying detailed causes and establishing countermeasures, and can also be used as simulation parameters for automated vehicles in the future. In this paper, we present the method to effectively derive context in the UCA identification stage related to driver interaction of automated vehicles.
