This document has been modified using ISO 26262-12:2018 Road Vehicles - Functional Safety - Part 12: Adaptation of ISO 26262 for Motorcycles.
The technical differences between this document and ISO 26262-12:2018, and the causes for these differences are as follows:
-- The normative reference GB/T 34590.1-2022 is used to replace ISO 26262-1, so as to adapt to the technical conditions of China and enhance the operability (see Chapter 3); ---The description of T and B is modified from “truck, bus, trailer and semi-trailer” into “goods vehicle, bus, special vehicle, trailer” (see 4.6; 4.6 of ISO 26262-8:2018), so as to maintain the consistency with the types of vehicles specified in GB/T 3730.1-2022 Terms and Definitions of Motor Vehicles, Trailers and Combination Vehicle - Part 1: Types;
---The description of “stress test” is modified from “stress tests” into “stress tests (such as: high load test and high environment test)” (see 10.4.3.4);
---The description of a suitable rationale for the CCP selection is modified from “a suitable rationale can be provided for the CCP selected” into “a suitable rationale shall be provided for the CCP selected” (see C.2).
This document also makes the following editorial modifications:
-- The sequence of paragraphs in the Scope is adjusted;
---The sub-clauses 8.4.5.1, 10.4.2.1 and 10.4.4.1 are deleted;

Road Vehicles - Functional Safety - Part 12: Adaptation for
Motorcycles
1 Scope
This document specifies the requirements for adaptation for motorcycles, including the following:
---general topics for adaptation for motorcycles;
---safety culture;
---confirmation measures;
---hazard analysis and risk assessment;
---vehicle integration and testing; and
---safety validation.
This document 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 road vehicles, excluding mopeds.
This document does not address unique E/E systems in special vehicles such as E/E systems designed for drivers with disabilities.
NOTE: other dedicated application-specific safety standards exist and can complement this document, or vice versa.
Systems and their components released for production, or systems and their components already under development prior to the publication date of this document, are exempted from the scope of this edition. This document addresses alterations to existing systems and their components released for production prior to the publication of this document by tailoring the safety lifecycle depending on the alteration. This document addresses integration of existing systems not developed according to this document and systems developed according to this document by tailoring the safety lifecycle.
This document addresses possible hazards caused by malfunctioning behavior of safety-related E/E systems, including interaction of these systems. It 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 behavior of safety- related E/E systems.
This document describes a framework for functional safety to assist the development of safety- related E/E systems. This framework is intended to be used to integrate functional safety activities into a company-specific development framework. Some requirements have a clear technical focus to implement functional safety into a product; others address the development process and can therefore be seen as process requirements in order to demonstrate the capability of an organization with respect to functional safety.
This document does not address the nominal performance of E/E systems.
Appendix A provides an overview on objectives, prerequisites and work products of this document.

3 Terms and Definitions
The terms and definitions defined in GB/T 34590.1-2022 are applicable to this document. 4 Requirements for Compliance
4.1 Purpose
This chapter describes how:
a) to achieve compliance with GB/T 34590;
b) to interpret the tables used in GB/T 34590; and
c) to interpret the applicability of each clause, depending on the relevant ASIL(s). 4.2 General Requirements
When claiming compliance with GB/T 34590, each requirement shall be met, unless one of the following applies:
a) tailoring of the safety activities in accordance with this document has been performed that shows that the requirement does not apply; or
NOTE 1: controllability can be validated using operating scenarios, including intended use and foreseeable misuse.
NOTE 2: one acceptance criterion for the safety validation might be a sufficient controllability in a safe state defined in GB/T 34590.3-2022, 7.4.2.5.
NOTE 3: a single acceptance criterion might not be sufficient to verify a safe state. b) the effectiveness of the external measures;
c) the effectiveness of the elements of other technologies; and
d) assumptions that influence the ASIL mapped from MSIL in the hazard analysis and risk assessment (see 8.4.4.4) that can be checked only in the final vehicle. EXAMPLE: if a mechanical component is assumed to prevent or mitigate a specific hazard potentially caused by a malfunction of an E/E system, the effectiveness of this component to prevent or mitigate that hazard is validated on vehicle level. 10.4.3.3 The safety validation at the vehicle level, based on the safety goals, the functional safety requirements and the intended use, shall be executed as planned using: a) the safety validation procedures and test cases for each safety goal including detailed pass/fail criteria; and
b) the scope of application. This may include issues such as configuration, environmental conditions, riding situations, operational use cases, etc. NOTE: operational use cases can be created to help focus the safety validation at the vehicle level. 10.4.3.4 An appropriate set of the following methods shall be applied:
a) repeatable tests with specified test procedures, test cases, and pass/fail criteria; EXAMPLE 1: positive tests of functions and safety requirements, black box testing, simulation, tests under boundary conditions, fault injection, durability tests, stress tests (such as: high load test and high environment test), highly accelerated life testing (HALT), simulation of external influences.
b) analyses;
EXAMPLE 2: FMEA, FTA, ETA, simulation.
c) long-term tests, such as vehicle driving schedules and captured test fleets; NOTE 1: long-term tests with targeted users can be infeasible for motorcycles. d) user tests under real-life conditions, panel or blind tests, expert panels; and
