Standards Development

Scope

This document is applicable to millimeter-wave radars (including 3D & 4D) installed on all types of road vehicles regardless of vehicle classifications, including passenger car, bus, commercial vehicles, trailer, etc. to measure or detect the surroundings of the vehicle.

Note: The definition of “Road Vehicles” includes M1~M3, N1~N3, L6~L7 according to consolidated resolution on the construction of vehicles (R.E.3).

This document specifies test methods for detection performance of automotive exterior sensing millimeter-wave radar (including 3D & 4D) applications and describes the following tests:

a) single target detection tests e.g., minimum detection range test;

b) multiple-target detection tests e.g., radar detection range separation test;

c) millimeter-wave radars performance tests for the ADAS/AD application scenarios.

Purpose

Millimeter-wave radars directly measure the spatial position and velocity of objects through the reflection and doppler effect of high-frequency electromagnetic waves. It is characterized by wide detection range and detection angle, high detection accuracy, and all-weather operation. As an allweather sensing device in autonomous vehicle, the millimeter-wave radar is of irreplaceable importance. The millimeter-wave radar has been successfully commercialized in the past two decades as one of the necessary sensors of Advanced Driving Assistant System (ADAS). 

So far, millimeter-wave radars are mainly designed based on various standards on enterprise and community level. The rapid development of Intelligent Connected Vehicle (ICV) technology and the accelerated evolution of millimeter-wave radar technology (e.g. 4D radar) bring new requirements. The absence of a number of generally accepted methods leads to an uncertain criterion with regards to parameter indicator for millimeter-wave radars in application and failure to decide the application level and performance, which has hindered the development of millimeter-wave radar industry and the improvement of the sensor technology and vehicle sensing technology. Therefore, it is necessary to develop corresponding ISO test standards to provide widely accepted standardized testing methods for automotive millimeter-wave radars.

To address the issues above, we propose the formulation of an ISO standard for millimeter-wave radars, which will cover single target performance test, multi-target separation test, anti-interference performance test, and on-vehicle performance test. The standard will provide certain parameters for reference in various millimeter-wave radar application scenarios on vehicle and for radar product comparison. It can serve as a reference for OEMs to achieve an adequate redundancy sensor performance. It contributes to establishing basic consensus on the definition of terms and test methods for automotive millimeter-wave radars, laying the foundation for knowledge exchange and technical cooperation among countries.

The purpose and benefit of this project:

-To establish widely accepted standardized testing methods for automotive millimeter-wave radars in order to rise to the challenges that OEM/Tier1 face due to the absence of some generally accepted methods.

-To address the lack of test method for critical performance test of automotive millimeter-wave radars parameters under vehicle level, particularly in mass-producing vehicles featured with ADAS/AD functions.

-To improve the redundancy performance of automotive millimeter-wave radars and to reduce the risk of false alarm rate in adverse weather conditions by adequately specifying the performance restrictions, thus to enhance driving safety
