1. What is LiDAR?

Laser radar (English: Lidar), laser radar is a system that integrates three technologies: laser, global positioning system (GPS), and IMU (inertial measurement unit). Compared with ordinary radar, laser radar has the advantages of high resolution, good concealment, and stronger anti-interference ability. With the continuous development of science and technology, the application of laser radar is becoming more and more extensive, and it can be seen in the fields of robots, unmanned driving, and unmanned vehicles. Laser radar is the main choice for high-level intelligent driving cars, and the independent development of domestic laser radar technology has important strategic significance.

2. LiDAR mass production

The mass production of LiDAR has started. As the most advanced automotive sensor system product, the performance evaluation of LiDAR chips, the testing and verification of the results of target and environment perception, etc. all require a complete solution for mass production LiDAR testing and verification.

[Comparison of the advantages and disadvantages of LiDAR and other sensor functions]

Sensor Type	Function	Advantages	Disadvantages
LiDAR	Surrounding 3D environment modeling	High-precision 3D model of the surrounding environment can be constructed	High cost and great impact on the environment
Millimeter wave radar	Assist in completing some functions of advanced driver assistance	Not affected by the shape and color of the object, and less affected by haze, rain and snow	Unable to detect the size and shape of objects, insensitive to non-metals
Ultrasonic radar	Side parking reminder, reverse parking reminder	Low cost and little impact on the environment	Slow speed, long launch time
Camera	Most ADAS functions can be realized with the help of algorithms. The distance measurement capability is weak but the algorithm is strong.	Can identify multiple types of objects and traffic lights	Greatly affected by light, overly dependent on algorithms

3. Development of the automotive-grade LiDAR industry

(1) From the perspective of the industry cycle, automotive-grade LiDAR has gone through the stages of technology initiation, introduction, and exploration, and has now entered a stage of rapid development. It can be seen that there is an industrial symbiotic relationship between the development of automotive-grade LiDAR and intelligent connected vehicles, and this symbiotic relationship will be further strengthened as the penetration of high-level autonomous driving vehicles increases;

(2) From the perspective of product status, ensuring the competitiveness of the automotive-grade LiDAR industry chain and the stability of the supply chain is of strategic significance;

(3) From the perspective of technology trends, semi-solid-state laser radar will dominate in the near future, while solid-state laser radar will most likely become the mainstream in the medium to long term;

(4) Judging from the competition landscape, foreign countries do not have a significant first-mover advantage. Although there is a gap between China and the rest, China can catch up. Under the situation of “letting a hundred flowers bloom”, automotive-grade LiDAR will enter an era of “combining vertical and horizontal forces” and “competing for supremacy in the Warring States Period”.

Automotive-grade LiDAR companies should grasp the four key words "automotive standards", "mass production", "performance" and "price", and at the same time improve the level of autonomy and controllability of automotive-grade LiDAR to prevent "bottlenecks".

AECQ100 certification [Huabi Laboratory]

Before any chip enters the production stage, it must pass a series of electrical, service life and reliability stress tests. For automotive chips, product testing is much more stringent than industrial or commercial chips. The goal of AEC-Q100 is to improve the yield rate of products. Due to stricter testing, more and more industrial customers are abandoning standard industrial-grade products and choosing AEC-Q100 certified parts instead.
