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.
