Road Vehicles - Functional Safety - Part 1: Vocabulary
1 Scope
This document defines the terms and definitions applied in GB/T 34590, as well as the
abbreviations.
This document is intended to be applied to safety-related systems that include one or more
electrical and / or electronic (E/E) systems and that are installed in series production road
vehicles, excluding mopeds.
This document does not address unique E/E systems in special vehicles, such as E/E systems
designed for drivers with disabilities.
NOTE: other dedicated application-specific safety standards exist and can complement this
document or vice versa.
Systems and their components released for production, or systems and their components already
under development prior to the publication date of this document, are exempted from the scope
of this edition. This document addresses alterations to existing systems and their components
released for production prior to the publication of this document by tailoring the safety lifecycle
depending on the alteration. This document addresses integration of existing systems not
developed according to this document and systems developed according to this document by
tailoring the safety lifecycle.
This document addresses possible hazards caused by malfunctioning behavior of safety-related
E/E systems, including interaction of these systems. It does not address hazards related to
electric shock, fire, smoke, heat, radiation, toxicity, flammability, reactivity, corrosion, release
of energy and similar hazards, unless directly caused by malfunctioning behavior of safety-
related E/E systems.
This document describes a framework for functional safety to assist the development of safety-
related E/E systems. This framework is intended to be used to integrate functional safety
activities into a company-specific development framework. Some requirements have a clear
technical focus to implement functional safety into a product; others address the development
process and can therefore be seen as process requirements in order to demonstrate the capability
of an organization with respect to functional safety.

3 Terms and Definitions
The following terms and definitions are applicable to this document.
3.1 architecture
representation of the structure of the item (3.84) or element (3.41) that allows identification of
building blocks, their boundaries and interfaces, and includes the allocation of requirements to
these building blocks
3.2 ASIL capability
capability of the item (3.84) or element (3.41) to meet assumed safety (3.132) requirements
assigned with a given ASIL (3.6)
NOTE: as a part of hardware safety requirements, achievement of the corresponding random
Creation of a new item (3.84) from an existing item (3.84)
NOTE: modification is used in GB/T 34590 with respect to re-use for lifecycle (3.86) tailoring. A
change is applied during the lifecycle (3.86) of an item (3.84), while a modification is
applied to create a new item (3.84) from an existing one.
3.92 modified condition/decision coverage; MC/DC
percentage of all single condition outcomes that independently affect a decision outcome that
have been exercised in the control flow
NOTE: MC/DC is a type of code coverage analysis. It builds on top of branch coverage (3.13),
and as such, it too requires that all code blocks and all execution paths have been tested.
3.93 motorcycle
road vehicle with two or three wheels driven by a power plant, the maximum design speed of
which is greater than 50 km/h, or one of the following conditions is satisfied:
---if internal combustion engine is used, its displacement is greater than 50 mL;
---if electric drive is used, the sum of the maximum continuous rated power of the motor
is greater than 4 kW.
However, the following category is not included:
motorized wheelchairs for the disabled, whose maximum design speed, complete vehicle curb
weight and external dimensions comply with relevant national standards and regulations.
[source: GB/T 5359.1-2019, 2.1]
3.94 motorcycle safety integrity level; MSIL
one of four levels that specify the item’s (3.84) or element's (3.41) necessary GB/T 34590 risk
(3.128) reduction requirements and convert to ASIL (3.6) for safety measures (3.141) to apply
for avoiding unreasonable residual risk (3.126) for items (3.84) and elements (3.41) used
specifically in motorcycle (3.93) applications, with D representing the most stringent and A the
least stringent level
3.95 multi-core
hardware component (3.21) which includes two or more hardware processing elements (3.113)
which can operate independently from each other
3.96 multiple-point failure
failure (3.50), resulting from the combination of several independent hardware faults (3.54),
which leads directly to the violation of a safety goal (3.139)
