Ambarella provides SoC for Dongfeng Driver Monitoring System

LinkedIn +

Ambarella, an AI vision silicon company, has partnered with Dongfeng Fengshen (Aeolus), a brand of the Dongfeng Motor Group, to build a Driver Monitoring System (DMS) based on its CV25 AI vision SoC and development platform. The first mass-production application of the system is in the Dongfeng Fengshen Yixuan Max, which launched this month.

The vehicle’s DMS, also known as a Fatigue Alarm System, uses vision-based imaging and deep-learning AI technology to detect the driver’s behavior and physiological state via eye-tracking and object detection, enabling an assessment of the driver’s cognitive and physical state. When the driver is driving dangerously, including while distracted, fatigued, dozing, smoking, talking on the telephone or other unsafe behaviors, the DMS will warn the driver within the pre-determined timeframe. Europe will begin to require DMS in vehicles manufactured from 2025 onward.

“This DMS safety system is the latest example of the practical, intelligent automotive technology solutions that Ambarella and Dongfeng Fengshen have cooperated on to achieve mass production,” said Fermi Wang, CEO of Ambarella. “We plan to continue this partnership, to help Dongfeng commercialize additional intelligent systems for its world-class vehicles.”

With high performance yet low power draw, Ambarella says its CV25 family of SoCs integrates Ambarella’s CVflow AI engine to accelerate various neural network algorithms. Additionally, good image quality is ensured by the SoC’s image signal processing unit, image processing algorithms, and optimization for specific camera modules and user scenarios. The SoC also provides stable and reliable encoding of multi-channel high-quality video, complies with the automotive Ethernet AVB protocol, and has passed the automotive TC8 conformance testing. Additionally, it has a built-in cybersecurity hardware engine.
