This Part is Part 10 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 26262-10.2012 “Road
vehicles - Functional safety - Part 10. Guideline”.
The technical differences between this Part and ISO 26262-10.2012 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;
● Replace ISO 26262-9.2011 with GB/T 34590.9-2017 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 10. Guideline
1 Scope
This Part of GB/T 34590 provides an overview of GB/T 34590, as well as giving
additional explanations, and is intended to enhance the understanding of the
other parts of this Standard. It has an informative character only and describes
the general concepts of GB/T 34590 in order to facilitate comprehension. The
explanation expands from general concepts to specific contents.
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 I 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).
In the case of inconsistencies between this Part and another part of this
Standard, the requirements, recommendations and information specified in the
other part of this Standard apply.

4.1 Functional safety for automotive systems (relationship with GB/T
34590)
GB/T 34590 is a generic standard and a basic safety standard about functional
safety of electrical/electronic/programmable electronic safety-related systems.
This means that industry sectors will base their own standards for functional
safety on the requirements of GB/T 34590.
In the automotive industry, there are a number of issues with applying GB/T
