Xpeng Motors Presents Autonomous Driving Architecture

Dr. Xinzhou Wu, Vice President of Xpeng’s Autonomous Driving at NVIDIA GTC China 2019 provided details of the autonomous driving architecture of the upcoming P7 intelligent sedan — a production vehicle to feature the NVIDIA DRIVE AGX Xavier system-on-a-chip (SoC) autonomous driving platform.

“Xpeng Motors is the first and only Chinese auto maker to have end-to-end closed-loop R&D capability for autonomous driving, and the only Chinese company that has built its proprietary synergetic sensor capability,” said Dr. Wu.

The P7’s Smart Electric Platform Architecture (SEPA) runs on a twin-chip system, with the NVIDIA Xavier SoC supporting XPILOT, and Qualcomm’s top-line vehicle processor Snapdragon™ 820A for intelligent services, along with a suite of cameras (including in-cabin camera), radars, HD-map, and ultrasonic sensors.

The P7 will carry next-generation millimeter wave radar with enhanced field of view and increased bandwidth, along with increased detection distance and angular accuracy. The P7’s advanced auto-parking function is supported by four 360-degree cameras, enabling the highest auto-parking success rate among existing production vehicles. Its positioning module has HD map resolution reaching decimeter level (relative positioning accuracy < 0.3%).

“Xpeng’s SEPA hardware architecture, one of the strongest in the industry, has a multi-sensor-based structure, providing autonomous driving solutions that are superior to vision-only solutions. The P7 can process input beyond line-of-sight visible range and will be able to utilize V2X technologies to process real-time data in the future, better managing beyond line-of-sight perception input,” said Dr. Wu.
