Hesaii's AT128 powers Didi and GAC Aion's L4 Robotaxi
Hesai's (HSAI) long-range automotive lidar AT128 has been selected as the lidar solution for the first L4 production-ready Robotaxi jointly unveiled by Didi Autonomous Driving, the self-driving technology arm of DiDi Global (DIDIY), and GAC Aion, a Chinese electric vehicle manufacturer and a subsidiary of the Guangzhou Automobile Group (GNZUF). Debuting at the 2025 GAC Tech Day and GAC Intelligent Safety Summit in Guangzhou, the vehicle is set to enter mass production this year, with initial deployment beginning in 2026. The new Robotaxi model features four Hesai AT128 lidar sensors, playing a central role in the vehicle's 360 degrees blind-spot-free perception system. The AT128 captures 1.53 million points of data per second. The Robotaxi integrates 33 sensors in total, using a heterogeneous sensor fusion architecture to deliver real-time, 360 degrees situational awareness. The L4 Robotaxi production model is the result of a multi-year strategic collaboration between Didi Autonomous Driving and GAC Aion. The vehicle combines GAC Aion's safety redundancy platform for L4 autonomous driving with Didi's upgraded hardware platform, multi-layered safety redundancy, and full-stack autonomous driving software.
