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 6 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 26262-6:2011 “Road
vehicles - Functional safety - Part 6: Product development at the software level”.
The technical differences between this Part and ISO 26262-6:2011 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 26262-4:2011 with GB/T 34590.4-2017 that modifies the
international standard;
● Replace ISO 26262-5:2011 that referenced by ISO 26262-6:2011 with
GB/T 34590.5-2017 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).

Part 6: Product development at the software level
1 Scope
This Part of GB/T 34590 specifies the requirements for product development at
the software level for automotive applications, including the following:
- requirements for initiation of product development at the software level,
- specification of the software safety requirements,
- software architectural design,
- software unit design and implementation,
- software unit testing,
- software integration and testing, and
- verification of software safety requirements.
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 sc...
