Hyundai Motor Company and Kia have announced that they will establish the “Hyundai Motor Group-KAIST On-Chip LiDAR Joint Laboratory” at KAIST’s headquarters in Daejeon, Korea, to develop lidar sensors for advanced autonomous vehicles.
The collaborative lab intends to create high-performance and small-sized on-chip sensor manufacturing technology, as well as innovative signal detecting technology, all of which are critical for the autonomous driving sector, where development competition is strong.
The on-chip sensor incorporates semiconductor technology to add numerous capabilities. If this technology is applied, lidar can be made smaller than previously, and price competitiveness can be ensured by mass production utilising semiconductor methods.
Furthermore, current autonomous driving sensors measure the distance to objects by measuring the time between emitting and returning light, whereas the method using FMCW (frequency modulated continuous wave), a next-generation signal detection technology, emits light that changes in frequency over time and detects the distance by measuring the frequency difference between returning light.
Compared to the existing one, the noise of the signal is less, and the relative velocity with the object can be calculated, and the interference of external light sources such as sunlight can be excluded, which is relatively advantageous in adverse weather environments.
The joint laboratory will consist of about 30 people, including research teams from Hyundai Motor Company and Kia Advanced Technology Institute, and research teams from the Faculty of Electrical and Electronic Engineering, including KAIST professors Kim Sang-hyun, Kim Sang-sik, Jung Wan-young, and Hamza Kurt, and will be operated for four years until 2028.
KAIST is in charge of detailed research in specialized areas for each research team, such as development of small on-chip lidar devices based on silicon photonics (optical semiconductors), production of high-speed, high-power drive integrated circuits (ICs) for lidar drive, and lidar system optimization design and verification.
Hyundai Motor Company and Kia will oversee the operation of the joint research laboratory together with Hyundai NGB, an industry-academia cooperation organization.
Hyundai Motor and Kia, which are leading autonomous driving technology, said that they expect to accelerate the era of fully autonomous driving through cooperation with KAIST, which has the world’s best technology, and will do their best to support the joint research lab to achieve tangible results.
Kim Sang-hyun, a senior professor at KAIST’s Joint Research Lab, said, “Lidar sensors, which are the eyes of automobiles, are a core technology for the development of autonomous vehicle technology in the future, and a technology that must be internalized by automakers” and added, “As the joint laboratory is established at a time when technology is very important, we will be able to lay the foundation for leading lidar-related technologies.”
