Abstract: Automotive functional safety is a necessary technical component of intelligent connected vehicles. This article introduces the background and development process of the ISO 26262 standard, the main content of the concept stage in the ISO 26262 standard and the setting method of automotive safety integrity level. Taking the function of the automatic driving system as an example, the work content of the functional safety of the automobile in the concept phase is explained, the functional safety goal of the automatic driving system is determined, and the specific functional safety requirements for each subsystem are analyzed and formed. Through research, development research and practice on the concept stage of automotive functional safety is carried out.

Key words: Automotive functional safety; Automotive safety integrity level; Functional safety goal; Functional safety requirement
