ISO 26262-9-2018 道路车辆--功能安全--第9部分:汽车安全完整性水平(ASIL)导向和安全导向分析 Road vehicles — Functional safety — Part 9: Automotive safety integrity level (ASIL)-oriented and safety-oriented analyses

This document is intended to be applied to safety-related systems that include one or more electrical 
and/or electronic (E/E) systems and that are installed in series production road vehicles, excluding 
mopeds. This document does not address unique E/E systems in special vehicles such as E/E systems 
designed for drivers with disabilities. 
NOTE Other dedicated application-specific safety standards exist and can complement the ISO 26262 series 
of standards or vice versa.
Systems and their components released for production, or systems and their components already under 
development prior to the publication date of this document, are exempted from the scope of this edition. 
This document addresses alterations to existing systems and their components released for production 
prior to the publication of this document by tailoring the safety lifecycle depending on the alteration. 
This document addresses integration of existing systems not developed according to this document and 
systems developed according to this document by tailoring the safety lifecycle.
This document addresses possible hazards caused by malfunctioning behaviour of safety-related E/E 
systems, including interaction of these systems. It does not address hazards related to electric shock, 
fire, smoke, heat, radiation, toxicity, flammability, reactivity, corrosion, release of energy and similar 
hazards, unless directly caused by malfunctioning behaviour of safety-related E/E systems.
This document describes a framework for functional safety to assist the development of safety-
related E/E systems. This framework is intended to be used to integrate functional safety activities 
into a company-specific development framework. Some requirements have a clear technical focus to 
implement functional safety into a product; others address the development process and can therefore 
be seen as process requirements in order to demonstrate the capability of an organization with respect 
to functional safety.
This document does not address the nominal performance of E/E systems.
This document specifies the requirements for Automotive Safety Integrity Level (ASIL)-oriented and 
safety-oriented analyses, including the following:
— requirements decomposition with respect to ASIL tailoring;
— criteria for coexistence of elements;
— analysis of dependent failures; and
— safety analyses.
