1 Scope

GB/T 34590.1-2022 is the vocabulary part of the road vehicle functional safety series, and in this field the vocabulary is not preliminary matter — it is where the arguments are settled. The whole framework rests on terms whose everyday meanings are close enough to mislead and whose technical meanings are exact: a fault is not a failure and neither is an error; a hazard is a potential source of harm arising from malfunctioning behaviour, not the malfunction itself; a safety goal is a top-level requirement derived from a hazard analysis rather than an aspiration; and the ASIL that determines how much rigour a development must carry is derived from severity, exposure and controllability, each with a defined meaning. A supplier and a manufacturer disputing whether a requirement has been met are almost always disputing a definition. This part defines the terms, definitions and abbreviations used throughout GB/T 34590. Under CCS T35, it is the foundation of the series and is written for everyone working to it: automotive electronics suppliers, vehicle manufacturers' safety functions, tool vendors and functional safety assessors.

This document defines the terms and definitions applied in GB/T 34590, as well as the

abbreviations.
