This document has been modified using ISO 26262-4.2018 Road Vehicles - Functional Safety
- Part 4.Product development at the system level.
The technical differences between this document and ISO 26262-4.2018, and the causes for
these differences are as follows.

1 Scope
This document specifies the requirements for product development at the system level for
automotive applications, including the following.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their
content constitutes requirements of this document. For dated references, only the edition cited
applies. For undated references, the latest edition of the referenced document (including any
amendments) applies.
GB/T 34590.1-2022 Road vehicles - Functional safety - Part 1.Vocabulary (ISO 26262-
1.2018, MOD)
3 Terms and definitions
For the purposes of this document, the terms, definitions and abbreviated terms given in GB/T
34590.1-2022 apply.
4 Requirements
For alternative entries, an appropriate combination of methods shall be applied in accordance
with the ASIL indicated, independent of whether they are listed in the table or not. If methods
are listed with different degrees of recommendation for an ASIL, the methods with the higher
recommendation should be preferred. A rationale shall be given that the selected combination
of methods or even a selected single method complies with the corresponding requirement.
5 General topics for the product development at the system level
The objective of this clause is to provide an overview of product development at the system
level.
The necessary activities during the development of a system are given in Figure 2.In an iterative
process, the technical safety concept is developed, incorporating technical safety requirements
and the system architectural design.
6 Technical safety concept
The technical safety concept is an aggregation of the technical safety requirements and the
corresponding system architectural design that provides rationale as to why the system
architectural design is suitable to fulfil safety requirements resulting from activities described
in GB/T 34590.3-2022 (with consideration of non-safety requirements) and design constraints.
7 System and item integration and testing
The integration of the item's elements is carried out in a systematic way starting from software-
hardware integration and verification through system integration and verification to vehicle
integration and verification. Specified integration tests are performed at each integration stage
to provide evidence that the integrated elements interact correctly.
8 Safety validation
Safety goals shall be validated giving consideration to variance in operation that impacts
the technical characteristics, which have been considered in the hazard analysis and risk
assessment.
