Xpeng Motors presents autonomous driving architecture and roadmap
“Xpeng Motors will prioritize its end-to-end autonomous driving R&D, introducing Level 3 autonomy in production models in 2020,” said Dr. Xinzhou Wu, Vice President of Xpeng's Autonomous Driving at Nvidia GTC China 2019 in Suzhou.
Wu provided details of the autonomous driving architecture of the upcoming P7 intelligent sedan—also on show at GTC China 2019—which the company states is the first 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 automaker 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 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 vehicle processor Snapdragon 820A for intelligent services, along with a suite of cameras (including in-cabin camera), radars, HD-map, and ultrasonic sensors.
"Xpeng's SEPA hardware architecture 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 Wu.
The company states that the P7 will be the first production vehicle to 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 a high auto-parking success rate. The P7's positioning module has HD map resolution reaching decimeter level (relative positioning accuracy < 0.3%), which the company states is the highest among existing production vehicles.
Xpilot has been through two generations of upgrades, and Xpilot 3.0's implementation on the P7 will reportedly enable Level 3 functions, including autonomous driving on highways, full-proprietary synergetic sensor capability, and AI-based intelligent cockpit, all in production vehicles in 2020. The company says that by 2021, Xpilot 3.5 will be able to perform full-scenario highway autonomous driving, upgradeable later to Xpilot 4.0 via OTA updates.
"We believe that having a central computing platform is key to autonomous driving solutions. The more scalable the system is, the more efficient for future data, mapping, and upgrading via OTA updates," added Wu.
