Foreword
GB/T 34590 “Road vehicles - Functional safety” consists of the following parts: - Part 1: Vocabulary;
- Part 2: Management of functional safety;
- Part 3: Concept phase;
- Part 4: Product development at the system level;
- Part 5: Product development at the hardware level;
- Part 6: Product development at the software level;
- Part 7: Production and operation;
- Part 8: Supporting processes;
- Part 9: Automotive Safety Integrity Level (ASIL)-oriented and safety- oriented analyses;
- Part 10: Guideline.
This Part is Part 9 of GB/T 34590.
This Part is drafted in accordance with the rules given in GB/T 1.1-2009. This Part uses the redrafting method to modify ISO 26262-9:2011 “Road
vehicles - Functional safety - Part 9: Automotive Safety Integrity Level (ASIL)- oriented and safety-oriented analyses”.
The technical differences between this Part and ISO 26262-9:2011 and their reasons are as follows:
- MODIFY the scope of this Part, from the original “applied to safety-related systems that include one or more electrical and/or electronic (E/E) systems and that are installed in series production passenger cars with a maximum gross vehicle mass up to 3 500 kg.” TO “applied to safety-related systems that include one or more electrical and/or electronic (E/E) systems and that are installed in series production passenger cars”;
- Regarding the normative references, this Part has made some adjustments with technical differences, to adapt to the technical conditions of China. The adjustments are mainly reflected in Clause 2 “Normative references”. The specific adjustments are as follows:
● Replace ISO 26262-1:2011 with GB/T 34590.1-2017 that modifies the
international standard;
● Replace ISO 26262-2:2011 with GB/T 34590.2-2017 that modifies the
international standard;
● Replace ISO 26262-3:2011 with GB/T 34590.3-2017 that modifies the
international standard;
● Replace ISO 26262-4:2011 with GB/T 34590.4-2017 that modifies the
international standard;
● Replace ISO 26262-5:2011 with GB/T 34590.5-2017 that modifies the
international standard;
● Replace ISO 26262-6:2011 with GB/T 34590.6-2017 that modifies the
international standard;
● Replace ISO 26262-8:2011 with GB/T 34590.8-2017 that modifies the
international standard.
This Part also made the following editorial changes:
- MODIFY the introduction of the international standard and its expression and the content of Figure 1.
This Part was proposed and shall be under the jurisdiction of National Technical Committee of Auto Standardization (SAC/TC 114).

Road vehicles - Functional safety - Part 9: Automotive
Safety Integrity Level (ASIL)-oriented and safety-
oriented analyses
1 Scope
This Part of GB/T 34590 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.
This Standard 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 passenger cars.
This Standard does not address unique E/E systems in special purpose
vehicles such as vehicles designed for drivers with disabilities.
Systems and their components released for production, or systems and their components already under development prior to the publication date of this Standard, are exempted from the scope of this Standard. For further
development or alterations based on systems and their components released for production prior to the publication of this Standard, only the modifications will be developed in accordance with this Standard.
This Standard addresses possible hazards caused by malfunctioning behaviour of E/E safety-related systems, including interaction of these systems. This Standard 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 E/E safety-related systems.
This Standard does not address the nominal performance of E/E systems, even if dedicated functional performance standards exist for these systems (e.g. active and passive safety systems, brake systems, Adaptive Cruise Control). 2 Normative references
