Technical Requirements and Test Methods for Advanced Emergency Braking Systems of Light-Duty Vehicles
1 Scope
This document specifies the general requirements, performance requirements, and determination of conformity of type for Advanced Emergency Braking Systems (AEBS) of Category M₁ and N₁ vehicles. It also describes the corresponding test methods.
This document applies to Category M₁ and N₁ vehicles.
Note: When no confusion arises, the term "system" is used as an abbreviation for "Advanced Emergency Braking System" throughout this document.

3 Terms and Definitions
For the purposes of this document, the terms and definitions given in GB/T 39263, GB/T 34590.1 and the following apply.
3.1
advanced emergency braking system; AEBS
System that continuously monitors the forward driving environment of the vehicle, provides a warning signal when a potential collision hazard exists, and automatically activates the vehicle's service braking system to decelerate the vehicle to avoid or mitigate a collision.
3.2
collision warning
Function where the system continuously monitors the vehicle's forward driving environment and provides a warning signal when a potential forward collision hazard exists.
3.3
emergency braking
Braking action resulting from a braking request issued by the system to the vehicle's service braking system, not intended for the purpose of tactile collision warning (3.2).
3.4
active state
State in which the system is performing collision warning (3.2) and/or emergency braking (3.3).
3.5
standby state
Inactive state in which the system meets the activation conditions and can be activated immediately.
3.6
unavailable state
State in which the system is neither on standby nor able to be activated.
3.7
initialization
Process, following vehicle start-up, where the system prepares for standby until it reaches the standby state (3.5).
3.8
relative collision velocity
Difference between the vehicle's velocity and the velocity of the collision target, in the direction of vehicle movement, at the moment of impact.
3.9
self-check
Continuous checking performed by the system to detect whether a fault has occurred.
Note: "Continuous" means without a noticeable time interval.
3.10
time to collision; TTC
Ratio, at a given moment, of the distance between the vehicle and a collision target to their relative speed, in the direction of vehicle movement.
3.11
kerb mass
Mass of the vehicle in running order, excluding the mass of the driver, passengers, and cargo.
Note: Fuel tank (if present, filled to 90% of its total capacity) and/or on-board energy storage device, coolant, lubricant at the level specified by the manufacturer, and complete with tools and spare wheel(s) (if provided as standard equipment by the vehicle manufacturer).
[Source: GB 20071-2025, 3.8]
3.12
electronic control system
Combination of a set of units (3.13) that together perform vehicle control functions by means of electronic data processing.
Note: This system is typically software-controlled and consists of separate functional components such as sensors, controllers and actuators, interconnected by transmission links. It usually includes mechanical, electro-pneumatic or electro-hydraulic units.
3.13
unit
The smallest subdivision of a system component that can be identified, analyzed, or replaced as a separate entity.
3.14
transmission links
Means of connecting internal units (3.13) for the purpose of transmitting signals, operational data, or energy supply.
Note: These are typically electronic, but may also be mechanical, pneumatic, hydraulic, or optical.
3.15
boundary of functional operation
Range of the external physical limits within which the system maintains control.
