GB/T 44373-2024 Intelligent and connected vehicle - Terms and definitions
1 Scope
This document defines the terms and definitions related to the basics, key technologies, system components and functional applications of intelligent and connected vehicles.
2 Normative References
No normative reference is included in this document.
3 Basics
3.1
intelligent and connected vehicle; ICV
vehicle with functions of environmental perception, intelligent decision-making and automatic control, or interaction with external information, or even collaborative control
Note: As shown in Figure 1, a vehicle with any one of functions a, b, and c is called an intelligent and connected vehicle. A vehicle that only has the intelligent function (6.1) is also called an intelligent vehicle; a vehicle that only has the connected function (6.2) can also be called a connected vehicle.
Key:
a—— Intelligent function (6.1)
b—— Connected function (6.2)
c—— Both intelligent function and connected function.

3.2
driverless vehicle
automated driving system-dedicated vehicle; ADS-DV
vehicle specially designed to be driven in an automatic manner which is not equipped with manually-operated components (ones used for steering, braking, acceleration and so on), except the ones for dealing with emergency and temporary control
Note: "Driverless vehicles" may, through remote control, temporarily deal with the situations that they fail to automatically handle, but they do not include the ones that are designed to be always driven through remote control.
3.3
functional safety
inexistence of unreasonable risk resulting from hazards caused by abnormal functional performance of electrical/electronic systems
3.4
safety of the intended functionality; SOTIF
inexistence of unreasonable risk resulting from hazards caused by inadequate functionality expected or achieved
3.5
vehicle cybersecurity
state in which a vehicle’s electronic and electrical systems, assembly and functions are protected so that its assets are free from threats
[Source: GB/T 40861-2021, 3.1]
3.6
multi-pillar approach
all-round verification and evaluation method for ICVs (3.1)
Note 1: "Multi-pillar method" includes audit/evaluation, simulation test, site test and road test and others.
Note: "Multi-pillar method" is generally used for the verification and evaluation on the driving automation system (5.1) of level 3 and above specified in GB/T 40429-2021.
3.7
intervention
user’s behavior that she/he actively influences the driving automation system (5.1) to perform dynamic driving tasks in an effective way that has been clearly defined by the system
3.8
request to intervene
Notification that the driving automation system (5.1) requests the DDT fallback-ready user to take over
[Source: GB/T 40429-2021, 2.13]
3.9
takeover
the DDT fallback-ready user respond to the request to intervene (3.8) to obtain the right to drive the from the driving automation system (5.1)
[Source: GB/T 40429-2021, 2.14]
3.10
functional safety management system
policies, procedures and processes used by to achieve functional safety (3.3) to deal with unreasonable risks resulting from hazards caused by abnormal functional performance of electrical/electronic systems
3.11
cybersecurity management system
risk-based systematic methods including organizational processes, accountability, and governance to deal with risks associated with vehicle cyber threats and protect vehicles from cyber attacks
