SEooC(Safety Element out of Context) is a method that assumes higher requirements in the application of automotive functional safety. To improve the quality of the assumed requirements, a method of applying SEooC through use case analysis is proposed. This study examined the basic SEooC methodology and defined how to apply the use case analysis method in detail. Through the case of developing a pressure sensor by applying SEooC, the upper requirements were derived by analyzing the use case. In addition, assuming system design, the internal safety requirements and requirements of use of SEooC target products were derived, and the hardware architecture was designed. When applying SEooC through use case analysis, the upper system can be defined and the safety goals, ASIL, and safety requirements can be derived based on clear evidence. In addition, the safety status and FTTI(fault-tolerant time interval) can be assumed in detail. |
