ADAS Sensor Modules from China: Radar & LiDAR
2 resources tagged with "Adas"
ADAS (Advanced Driver Assistance Systems) hardware out of China centers on two sensor types: 77GHz FMCW radar (TI AWR / NXP TEF810X chipsets) and LiDAR from makers like Hesai, Livox, and Robosense. Both demand AEC-Q100-qualified silicon because they live in the vehicle, and LiDAR adds two more wrinkles — 905nm vs 1550nm laser choice and potential export-control exposure on higher-end units. The recurring sourcing risk is consumer-grade parts substituted into automotive modules, which is why component-grade verification matters more here than in most categories.
When you source ADAS sensors, the pitfalls are unqualified silicon, export restrictions on advanced LiDAR, and integration effort (often ROS-based). We verify AEC-Q100 grades and confirm regional RF certification for radar before sign-off.

FAQ
Which Chinese suppliers make automotive LiDAR?
Hesai, Livox, and Robosense are the established names, offering spinning, solid-state, and MEMS designs. Choice of 905nm vs 1550nm affects range, eye-safety, and cost, and some advanced units carry export-control considerations.
Do ADAS modules need automotive-grade parts?
Yes — the silicon should be AEC-Q100 qualified, since these run in-vehicle across the full temperature and vibration range. Verify the grade on the actual transceiver, not just the module marketing.
What certification does ADAS radar need?
77GHz radar needs FCC (US) or ETSI (EU) authorization for the 76–81 GHz band, plus AEC-Q100 on the RF silicon for vehicle use.
