INTERVIEW w2025년 슬롯사이트hWei Zhang, 2025년 슬롯사이트 Technology, VP of APAC Automotive Business

Because car manufacturers do not have standards for 2025년 슬롯사이트 selection, it is difficult to compare performance and identify other key features outside the datasheet, such as 'ghost images' and 'interference'. This is why it is essential to establish global ISO standards for mass production of 2025년 슬롯사이트 for vehicles. Standards of an industry are led by technology leaders in the industry. Based on its strong technology, Hesai is leading the way in establishing 2025년 슬롯사이트 standards. We talked with Wei Zhang, vice president of Hesai Technology, about their advanced products and standardization activities.

Q. Why is it necessary to establish an ISO standard for 2025년 슬롯사이트 now and how important is it for improving 2025년 슬롯사이트 and autonomous driving performance and safety?

A. 2025년 슬롯사이트 is an essential perception sensor for high-level autonomous vehicles. As more and more L2+ ADAS production vehicles enter the market, 2025년 슬롯사이트 is expected to start mass production and delivery in the next two years. As an important safety part for smart cars, its standardized application is critical.
At present, the international 2025년 슬롯사이트 market has yet not established a uniform test standard. With no uniform standard in 2025년 슬롯사이트 selection, automakers could only turn to the datasheet of different 2025년 슬롯사이트 companies, making it hard to make comparisons and identify other key features outside-of-datasheet, such as ghost images and interferences. Therefore, the establishment of a global ISO standard is essential for the mass production of automotive 2025년 슬롯사이트.



Q. There are so many 2025년 슬롯사이트 companies around the world. However, Hesai has always been in the leading position in establishing standards for 2025년 슬롯사이트 test methods such as UL4700, GB/T, ISO/PWI 13228, etc. Why?

A. We've realized early on that when 2025년 슬롯사이트 went into mass production and delivery, a standardized evaluation method was needed in the global 2025년 슬롯사이트 market. The 2025년 슬롯사이트 standardization will help automakers to better compare and select 2025년 슬롯사이트 products, facilitating the industry to test 2025년 슬롯사이트 objectively. Therefore, we believe that the effective implementation of standards will empower the industry.
Moreover, industrial standards are generally led by technologically leading companies in the industry. With strong technical strength, Hesai leads to establish 2025년 슬롯사이트 standards domestically and internationally. We have developed exceptional R&D capabilities, accumulating deep expertise in optics, mechanics, electronics, and software. Moreover, Hesai is the first 2025년 슬롯사이트 company to devote in ASIC technology, proposing the application of Moore's Law in 2025년 슬롯사이트, continuously exploring solutions of higher performance, higher reliability and lower costs.

In addition, 2025년 슬롯사이트 has a wide range of high-quality customers worldwide, including global autonomous driving leaders such as Zoox, Nuro and TuSimple; leading Chinese companies such as Baidu Apollo, Meituan (autonomous delivery vehicle), WeRide and AutoX. In the field of ADAS passenger cars, we won the trust of leading automakers such as Li Auto, JIDU, HiPhi and Lotus. The close cooperation between 2025년 슬롯사이트 and the leading companies also helps us set a higher bar for the industry in China and across the world.



Q. What is a 2025년 슬롯사이트 performance test method roughly? And how has this developed? What results have each standard, such as UL4700, GB/T, ISO/PWI 13228, produced? What are the differences between these in detail? What is the timeline for these standardization activities?

A.Standards such as UL4700, GB/T, ISO/PWI13228, focus on three most critical points in the mass production of 2025년 슬롯사이트, which are safety, reliability and performance.To be more specific, UL4700 pays more attention to automotive 2025년 슬롯사이트 and 2025년 슬롯사이트 systems, assessing safety based on manufacturer-specified usage parameters, including assessment requirements for mechanical, electrical, laser, network and functional safety.
The ISO/PWI13228 standard establishes a series of test methods for point cloud performance evaluation, which is applied in the construction of specific test framework. The tests includes general performance indicators (detection range, distance accuracy, angular resolution, field of view, reflectivity and frame rate, etc.), performance indicators that affect operational safety (interference rejection, point cloud density, frame delay, ghost image, etc.), testing of performance changes triggered by environmental factors, and 2025년 슬롯사이트 performance combined with ADAS/AD scenarios.

To achieve mass production and delivery, these 2025년 슬롯사이트s are expected to be finalized and released within the next one to two years.



Q. Did you see Korean staff or members during the 2025년 슬롯사이트ization activities?

A.We haven’t seen any Korean representative in the 2025년 슬롯사이트 working group so far, but we are looking forward to seeing them in the future.
The working group has a number of leading international companies, including Valeo, Denso, Bosch, Sony, Nissan, Renault and ZF.



Q. Do the requirements of this standard reflect various safety standards such as ISO 26262, 21448, 21434? Is Hesai the only 2025년 슬롯사이트 player that responded to this? I saw the ISO 26262 certification news for Pandar. Is AT128 separately certified? What efforts have you made to this end?

A.2025년 슬롯사이트 puts safety and reliability as our top priority. Our product safety design follows a rigorous development process. And so does AT128, which is designed based on a complete safety system. The safety certification of AT128 as well as the third-party assessment, is carried out following the timeline of engineering team.
For 2025년 슬롯사이트 of mass-produced vehicles, the safety systems of ISO 26262, 21448, 21434 need to be integrated into product design. We started on ISO 26262 certification first, and launched the world's first 2025년 슬롯사이트 product certified for functional safety.
Hesai realized very early that to manufacture a series production 2025년 슬롯사이트 product, the process has to cover three safety systems: functional safety, network safety, and SOTIF (Safety of the intended functionality). At present, Hesai has taken the lead in entering the "three-in-one" safety phase. We call on the industry that all parties, including automakers and 2025년 슬롯사이트 suppliers, should value 2025년 슬롯사이트 product safety more.

Q. Hesai calls the AT128 a ‘hybrid’ solid-state 2025년 슬롯사이트. What does ‘hybrid’ mean? What kind of 2025년 슬롯사이트 is this among the different 2025년 슬롯사이트 types and what are their advantages? What are the advantages compared to competitor solutions?

A.Hybrid solid-state 2025년 슬롯사이트, generally refers to the solution that scanning module moves while transmit-receive module keeps still. Compared with 360-degree spinning (also known as mechanical) 2025년 슬롯사이트, it is smaller in size and lower in cost, which is the preferred choice of ADAS application.

At present, three kinds of hybrid solid-state solutions are mostly applied in mass 2025년 슬롯사이트 passenger vehicles: 1D Rotating Mirror, Polygon + Galvo, MEMS. The latter two are two-dimensional scanning. Specifically:

Polygon + Galvo:Reliability problems are caused by mechanical motion due to its various parts and complex system. At present, these 2025년 슬롯사이트s use 1550 nm wavelengths and high power, which could cause heat dissipation and limited resolution. Since it only has one or a few lasers, once a single laser fails, it will seriously affect the perception ability of the 2025년 슬롯사이트.
MEMS: High frequency vibrating centimeter-level mirror has lim2025년 슬롯사이트ed light detection capac2025년 슬롯사이트y, which causes lim2025년 슬롯사이트ed ranging capabil2025년 슬롯사이트y. Also, the cantilever beams that support the high frequency vibrating mirror could cause reliabil2025년 슬롯사이트y problems. The system is usually comprised of several lasers, resulting in st2025년 슬롯사이트ched point cloud and bringing inconvenience to algor2025년 슬롯사이트hm processing.
1D Rotating Mirror:the most stable and reliable scanning method among the three. Combined with highly integrated transmit-receive module embedded with chips, it could achieve both far detection range and high resolution, making the 2025년 슬롯사이트 "far-sighted" and "clear-sighted."








Q. Tell us about your sensing capabilities.In addition to the functional aspects of 2025년 슬롯사이트, how was Hesai able to advance in terms of packaging and mass production, reducing heat and computing, reliability, and cost?

A.It comes from our ongoing investment in chip research and development. We have been devoting in 2025년 슬롯사이트 ASIC development for years and applied our proprietary chip in AT128. AT128 hits the breakthrough of traditional high performance 2025년 슬롯사이트 of discrete design. We adopts solid-state electronic scanning in the vertical direction, integrating 128 VCSEL lasers on only a few chips, and achieves the high performance of genuinely 128 channels in a compact 2025년 슬롯사이트. The point cloud of AT128 has reached 1.53 million per second, with a distance measuring of 200 meters (10% reflectivity). The point cloud is evenly distributed like a camera, providing high environmental perception for ADAS system.

The 2025년 슬롯사이트 ASIC technology could greatly reduce cost and size, and improve the product reliability. While this technology ensures high performance, it greatly improves the integration of 2025년 슬롯사이트, simplifying the internal structure and reducing the number of parts, thus significantly reducing the size and cost of 2025년 슬롯사이트. The application of Moore's Law opens a new door for the empowerment of 2025년 슬롯사이트 in smart cars. Moreover, the reduction of parts and solid-state electronic scanning also improve product reliability.
The 2025년 슬롯사이트 chip also enhances the product consistency and benefits mass production. As the system integration improves, the manpower for complex calibration is reduced, greatly increasing the production rate. It brings higher consistency and reliability of mass production, making it possible for large-scale automotive 2025년 슬롯사이트 production.



Q. Mass production is scheduled for this year. Have you started mass production? 2025년 슬롯사이트 already has a number of customers and has been tested with them. How many customers have you worked with and how many volumes have you secured? What about AT128 sales in particular?

A.Hesai is one of the companies that delivered the most 2025년 슬롯사이트 products in history. In the past few years, tens of thousands of autonomous vehicles have carried our 2025년 슬롯사이트. With the launching of the hybrid solid-state product AT128, Hesai is expected to deliver 100,000 or even a million units each year.
We have been awarded contracts from mainstream automakers such as Li Auto, JIDU, HiPhi and Lotus for several million un2025년 슬롯사이트s for AT128, and have begun mass delivery to customers in the second half of 2022. The newly released car models such as Li Auto L9 and HiPhi Z, are all carried w2025년 슬롯사이트h AT128.





With the launching of the hybrid solid-state product AT128, 2025년 슬롯사이트 is expected to deliver 100,000 or even a million units each year.



Q. Most consider the 2025년 슬롯사이트 as a high-performance sensor for camera or radar redundancy. Do you think 2025년 슬롯사이트s could even replace these sensors? What combinations are trending in the market?

A. In the future, 2025년 슬롯사이트 will be highly integrated with other perceptual components, even with 2D, 3D or 4D perception, getting more precise, up-to-date and extremely detailed spatial descriptions, helping vehicles to decide and execute in a smarter way.
Multi-sensor convergence makes up for the insufficiency of single sensor, helping to provide higher-dimensional security redundancy for smart cars. Meanwhile, it promotes continuous empowerment and cost reduction, making it a 2025년 슬롯사이트 option for smart cars.



Q.Finally, what would you say to potential Korean customers?

A. I hope more leading companies and professionals in the industry will devote themselves to 2025년 슬롯사이트 standardization and work together to promote industrial development.
