On December 4, the "Lingxuan Award", an authoritative award in the automotive industry, was officially announced in Wuhan. Vanji Technology's new CMOS process-compatible all-solid-state lidar chip won the Excellence Award in the integrated circuit category of this year's Lingxuan Award.
The all-solid-state lidar chip developed by Wanji Technology uses the most advanced silicon light and semiconductor integration technology to solve a series of problems existing in existing lidar products such as low reliability, difficulty in integration, and high cost. It is forward-looking and disruptive.
Based on silicon photonics technology, radar chips and microelectronic chips achieve wider integration.
The "Made in China 2025 Strategy" clearly states that by 2025, we will master the overall technology and key technologies of autonomous driving, establish a complete independent research and development system, production supporting facilities and industrial groups for intelligent connected vehicles, and basically complete the transformation and upgrading of the automobile industry.
Lidar is the core environmental sensing component of autonomous vehicles and is evolving towards chip development.
Wanji Technology's new all-solid-state lidar chip not only has the characteristics of miniaturization and high performance, but also can meet the low-cost needs of large-scale mass production.
In terms of performance, the new silicon-based lidar has greatly improved its reliability because it abandons the mechanical drive system. At the same time, the beam divergence angle can be compressed to the diffraction limit, reaching about 0.08°, and has extremely high resolution.
This enables it to achieve clear resolution of targets such as vehicles at long distances. Through flexible control of the beam, it can also scan local features with smaller resolution, greatly improving the recognition ability.
Lidar is a precision sensor that integrates light, machinery and electricity. Its core technology and key components rely on foreign supplies, and the product prices are high.
Wanji Technology's new CMOS process is compatible with all-solid-state lidar and adopts independent technology, breaking through foreign monopoly on basic optoelectronic devices and significantly reducing the cost of autonomous driving lidar by 70% - 80%, thus realizing the localization and cost-effectiveness of high-end automotive lidar.
The safety and controllability of human-driven car parts.
Vanji Technology has more than ten years of research and development experience in the laser field. The new silicon-based lidar chip is the latest product developed by Vanji Technology for future high-end autonomous driving.
Since it began to self-research related chip technologies in 2016, the company has been conducting basic research for 6 years. Related projects have successively received funds from the National Natural Science Foundation, key projects of the Beijing Municipal Science and Technology Commission, and Zhongguancun Disruptive Technology R&D and Achievement Transformation Projects.
support.
The company has applied for 32 related invention patents, including 6 PCT patents, 3 U.S. patents, and 2 European patents. A total of 6 patents have been authorized, including 3 inventions, 2 utility models, and 1 U.S. patent.
According to the plan, the company will release a silicon-based all-solid-state lidar with a range of 30 meters in 2022, and a silicon-based all-solid-state lidar in 2024.
