This document is modified in relation to ISO 26262-9.2018 Road Vehicles - Functional safety - Part 9.Automotive Safety Integrity Level (ASIL)-oriented and Safety-oriented Analyses. The technical differences between this document and ISO 26262-9.2018, and the causes for these differences are as follows. -- The description of T&B vehicles is changed from “trucks, buses, trailers, and semi-trailers” to “goods vehicles, buses, special vehicles, and trailers” (see 4.6; see 4.6 of ISO 26262-9.2018), so that the vehicle types are consistent with that specified in GB/T 3730.1-2022 Terms and Definitions of Motor Vehicles, Trailers and Combination Vehicle - Part 1.Types. This document also makes the following editorial modifications. -- The order of paragraphs in the Scope is adjusted; -- The normatively referenced GB/T 34590.12-2022 is included in the list in Chapter 2; -- The addresses of the terminology database maintained by ISO and IEC for standardization in Chapter 3 of ISO 26262-9.2018 are deleted; -- The clause number 6.5.1 in ISO 26262-9.2018 is deleted.

The issuing of the previous versions. -- Issued for the first time in 2017 as GB/T 34590.9-2017; -- This is the first revision.1 ScopeThis document specifies the requirements for Automotive Safety Integrity Level (ASIL)-oriented and safety-oriented analyses, including the following.2 Normative referencesThe following documents contain the provisions which, through normative reference in this document, constitute the essential provisions of this document. For the dated referenced documents, only the versions with the indicated dates are applicable to this document; for the undated referenced documents, only the latest version (including all the amendments) is applicable to this document. GB/T 34590.1-2022 Road Vehicles - Functional Safety - Part 1.Vocabulary (ISO 26262-1.2018, MOD)3 Terms and definitionsThe terms and definitions defined in GB/T 34590.1-2022 apply to this document.4 RequirementsThe results of safety activities are given as work products. “Prerequisites” are information which shall be available as work products of a previous phase. Given that certain requirements of a clause are ASIL-dependent or may be tailored, certain work products may not be needed as prerequisites. For items or elements of motorcycles for which requirements of GB/T 34590.12-2022 are applicable, the requirements of GB/T 34590.12-2022 supersede the corresponding requirements in this document and GB/T 34590.2-2022.5 Requirements decomposition with respect to ASIL tailoringThe requirements specific to the random hardware failures, including the evaluation of the hardware architectural metrics and the evaluation of safety goal violations due to random hardware failures (see GB/T 34590.5-2022, Chapter 8 and Chapter 9) remain unchanged by ASIL decomposition.6 Criteria for coexistence of elementsIn the case of the coexistence of sub-elements that have different or no ASILs assigned, or the coexistence of non-safety-related sub-elements with safety-related ones, it can be beneficial to avoid assigning the ASIL of the element to all the sub-elements.7 Analysis of dependent failuresIndependence is threatened by common cause failures and cascading failures, while freedom from interference is only threatened by cascading failures.8 Safety analysesThe objective of safety analyses is to ensure that the risk of a safety goal violation due to systematic faults or random hardware faults is sufficiently low. Depending on the application, this is achieved by. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
