Standards Development

Scope

This standard applies to lidars installed on road vehicles to measure or detect the surroundings of the vehicle.

This standard applies to lidars used on all types of road vehicles regardless of vehicle classifications, including passenger cars, buses, commercial vehicles, trailers, etc.

This standard describes a series of test methods to assist in evaluating the performance of lidars. The tests should cover the following:

1. The common performance specifications (e.g. Range capability, Range precision).

2. The common performance characteristics (e.g. Anti-interference, Ghost points).

3. Possible alteration of performance test caused by environmental conditions.

4. Lidar performance for the union of both ADAS/AD application scenarios.

This standard does not address test methods for reliability, functional safety, and cybersecurity.

Note:

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

Purpose

Currently, the automotive lidar industry faces significant challenges in the context of ADAS/AD use: Lidar plays a vital role in automotive driving, utilizing the laser to measure distance and detect obstacles. As an essential sensor in the sensing system, automotive lidar possesses the characteristics of long-distance measurement, high accuracy, and fast frequency. The lidar could obtain the distance and orientation of objects directly. Therefore, automotive lidar is regarded as one of the crucial sensors in the autonomous driving system by OEMs and Tier 1. With the rapid development of autonomous driving technology, the demand for automotive lidar is gradually increasing. The automotive lidar market is expected to experience substantial growth in the next few years.

However, due to the lack of international technical standards or general specifications for lidar products, describing lidar performance can vary significantly. Furthermore, testing and verifying lidar performance according to different standards and specifications is inconsistent. This lack of a unified standard impedes the healthy development of the industry. Therefore, it is urgent to formulate unified international standards, to provide a reference for common performance specifications and characteristics.

To address this issue, we propose the formulation of a lidar standard in the ISO, which can be used for reference by all countries in the world and mainly related to the common performance specifications, the common performance characteristics, possible alteration on performance test caused by environmental conditions, and lidar performance for the union of both ADAS/AD application scenarios. It is essential to establish a unified lidar standard that can promote the continuous improvement of lidar product performance and quality. A unified lidar standard that serves as a benchmark for comparing performance across various models could mitigate potential automotive safety risks. It contributes to establishing basic consensus on the definition of terms and technical specifications for automotive lidar, laying the foundation for knowledge exchange and technical cooperation among countries.

The purpose and benefits of this project will be:

- To solve the challenges that OEM/Tier1 face when evaluating lidars during the selection process due to the lack of a unified automotive lidar performance test method.

- To address the lack of critical performance test references for automotive lidar, particularly in the context of mass-producing vehicles equipped with ADAS/AD functions

- To reduce the risk of incorrectly perceiving the environment after vehicles hit the road by ensuring that lidar performance limitations are adequately specified. This, in turn, will improve road vehicle safety.

- To establish basic consensus on the definition of terms and technical specifications for automotive lidar, laying the foundation for knowledge exchange and technical cooperation among countries.
