1 SCOPE<\/div>\n
This document specifies the functional safety related activities and work products for the safety-related electrical and\/or electronic (E\/E) systems at the hardware level, and the requirements for and methods of making functional safety audit and assessment, so as to check and verify the compliance of the development process and work products with the functional safety.<\/div>\n
This document is applicable to the safety-related systems that include one or more E\/E systems and that are installed in series production road vehicles, excluding mopeds.<\/div>\n
This document is not applicable to the specific E\/E systems in special purpose vehicles such as E\/E system designed for drivers with disabilities.<\/div>\n

3 TERMS AND DEFINITIONS<\/div>\n
For the purpose of this document, the terms and definitions given in GB\/T 34590.1-2022 apply.<\/div>\n
4 GENERAL REQUIREMENTS<\/div>\n
For the purpose of this document, the audit and assessment requirements specified in GB\/T 43253.1-2023 apply.<\/div>\n
The functional safety audit and assessment at the hardware level mainly involve the following information:<\/div>\n
\uf0be Specification of hardware safety requirements;<\/div>\n
\uf0be Hardware design;<\/div>\n
\uf0be Evaluation of the hardware architectural metrics;<\/div>\n
\uf0be Evaluation of safety goal violations due to random hardware failures;<\/div>\n
\uf0be Hardware integration and verification;<\/div>\n
\uf0be Evaluation of hardware elements.<\/div>\n
Through audit and assessment, check the functional safety development at the hardware level based on evidences to confirm that:<\/div>\n
\uf0be The hardware safety requirements are appropriate and complete;<\/div>\n
\uf0be Ensure the hardware can fulfill the hardware functional safety requirements and meet the hardware-software interface (HSI) specification, through design and verification;<\/div>\n
\uf0be Provide evidence based on the hardware architectural metrics for the suitability of the hardware architectural design of the item with respect to detection and control of safety-related random hardware failures;<\/div>\n
\uf0be Ensure the hardware developed meets the hardware safety requirements;<\/div>\n
\uf0be Ensure the functional behavior of hardware elements is adequate to meet the allocated safety requirements.<\/div>\n
