Lucid Air ADAS Controller Automotive Deep Dive Teardown

The Lucid Air is an electric sports sedan produced by the Chinese EV manufacturer Lucid. Lucid provides DCU (Drive Control Unit) for the ADAS system, which is an important component of the vehicle's powertrain system. The system includes adaptive cruise control, automatic emergency braking, lane departure warning, and other advanced safety features. It uses a combination of cameras, radar, and other sensors to provide real-time feedback to the driver and help prevent accidents.

For the Lucid Air, this system is a key feature of the advanced driver assistance capabilities and is designed to enhance driver safety and convenience. For this device, Micron supplied 96 GB Mobile LPDDR4 SDRAM (32GB (8 x 4 GB) on single board), and Samsung supplied 768 GB and 384 GB NAND Flash. High-speed communication like Gigabit Multimedia Serial Link (GMSL) uses chips from Analog Devices but for Ethernet, they were Marvell Semiconductor and Realtek. A temperature sensor was provided by Texas Instruments and is responsible for overheating protection. In the Lucid Air ADAS controller, there were three identical main boards connected via a MateNet network cable to increase the performance of the device.
