GB/T 34590.4-2017 Road vehicles—Functional safety—Part 4:Product development at the system level
Basic Information
Scope
This part of GB/T 34590 specifies the requirements for vehicle product development at the system level, including: -- Initiating system-level product development; -- Defining technical safety requirements; -- Technical safety concepts; -- System design; -- Integration and testing of related items; -- Safety confirmation; -- Functional safety assessment; and -- Production release. This standard applies to safety-related systems installed in mass-produced passenger vehicles that include one or more electronic and electrical systems. This standard does not apply to specific electronic and electrical systems on 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 release or to systems and their components developed before the date of this standard's publication. For further development or changes to systems and their components that completed production release before the publication of this standard, only the modified parts need to be developed in accordance with this standard. This standard addresses potential hazards caused by the faulty behavior of electronic and electrical safety-related systems, including those that may arise from the interaction of these systems. This standard does not address hazards related to electric shock, fire, smoke, heat, radiation, toxicity, flammability, reactivity, corrosion, energy release, etc., unless the hazards are directly caused by the faulty behavior of electronic and electrical safety-related systems. This standard does not address the nominal performance of electronic and electrical systems, even if these systems (such as active and passive safety systems, braking systems, adaptive cruise control systems) have dedicated functional performance standards.
