GB/T 34590.5-2017 Road vehicles—Functional safety—Part 5:Product development at the hardware level
Basic Information
Scope
This part of GB/T 34590 specifies the requirements for vehicle product development at the hardware level, including:
—— Requirements for initiating hardware-level product development;
—— Definition of hardware security requirements;
—— Hardware design;
—— Hardware architecture measurement; and
—— Evaluation of hardware integration and testing for violations of safety objectives due to random hardware failures.
The requirements for hardware elements in this part apply to non-programmable elements and programmable elements such as ASICs, FPGAs, and PLDs. Moreover, the requirements in Chapters 11 and 12 of GB/T 34590.6—2017 and GB/T 34590.8—2017 apply to programmable electronic elements.
This standard applies to safety-related systems that include one or more electronic and electrical systems installed in mass-produced passenger vehicles.
This standard does not apply to specific electronic and electrical systems in special-purpose vehicles, such as those designed for disabled drivers.
This standard does not apply to systems and their components that have already completed production and release, or to systems and their components developed before the date of publication of this standard. For systems and their components that have completed production and release before the publication of this standard, only the modified parts need to be developed in accordance with this standard.
This standard targets the potential hazards caused by the faulty behavior of electronic and electrical safety-related systems, including those caused by the interaction of these systems. This standard does not target hazards related to electric shock, fire, smoke, heat, radiation, toxicity, flammability, reactivity, corrosivity, energy release, etc., unless these hazards are directly caused by the faulty behavior of electronic and electrical safety-related systems.
This standard does not target the nominal performance of electro
