GB/T 34590.4-2022 Road vehicles—Functional safety—Part 4:Product development at the system level

Scope

This document specifies the requirements for vehicle product development at the system level, including:
—— General guidelines for starting system-level product development;
—— Definition of technical safety requirements;
—— Concept of technical safety;
—— System architecture design;
—— Integration and testing of related items;
—— Safety confirmation.
This document applies to safety-related systems that include one or more electrical/electronic systems installed on mass-produced road vehicles except for light motorcycles.
This document does not apply to specific electrical/electronic systems on special-purpose vehicles, such as vehicle systems designed for disabled drivers.
Note: Other dedicated safety standards can be used as supplements to this document, and vice versa.
Systems and their components that have already been released for production or are being developed before the date of this document's release are not applicable to this document. When changes are made to systems and their components that have been released for production before the date of this document's release, this document applies to the safety lifecycle activities based on these changes. When integrating systems developed without this document with systems developed in accordance with this document, the safety lifecycle activities need to be tailored in accordance with this document.
This document addresses potential hazards caused by functional abnormalities of safety-related electrical/electronic systems, including potential hazards caused by the interaction of these systems. This document does not address hazards related to electric shock, fire, smoke, heat, radiation, toxicity, flammability, reactivity, corrosivity, energy release, etc., unless the hazards are directly caused by functional abnormalities of safety-related electrical/electronic systems.
This document proposes a framework for functional safety developmen
