L4 Autonomous Cold-Chain Vehicles Begin Yunnan Deployment

MINIEYE And Yunnei Power Begin Production

Shenzhen Youjia Innov Tech Co., Ltd. (MINIEYE) has announced that the first batch of L4 autonomous cold-chain vehicles, Xiaozhu A6 Pro, has rolled off the production line at Kunming Yunnei Power Co., Ltd.’s Kunming plant. Jointly developed by the two companies, the vehicles are planned for deployment across Kunming, Chuxiong, Baoshan, Lijiang, and other areas of Yunnan Province. The production milestone marks the transition from joint product development into mass manufacturing and field deployment, with the vehicle designed specifically for refrigerated logistics operations that require controlled cargo conditions and autonomous driving capability.

Joint Development And Autonomous Driving Architecture

Shenzhen Youjia Innov Tech Co Ltd and Kunming Yunnei Power Co Ltd jointly completed the Xiaozhu A6 Pro’s product definition, research and development, and mass-production work. Yunnei Power is responsible for vehicle manufacturing, the chassis platform, system integration, and supply-chain support, while MINIEYE supplies an L4 mapless autonomous driving solution. The vehicle uses MINIEYE’s self-developed iPilot 4 Max domain controller, which features a domestic hardware architecture and AI foundation model technology. The system does not require regional map adaptation and supports hour-level deployment, enabling the autonomous driving platform to be introduced across operating areas without the conventional need for location-specific map preparation.

Refrigerated Cargo Capabilities

The Xiaozhu A6 Pro is equipped with a Class F refrigerated cargo box that integrates heating and cooling functions and maintains temperatures from -20°C to +25°C with an accuracy of ±1°C. This specification is designed to support cold-chain transportation where stable cargo conditions are essential throughout delivery operations. The vehicle also incorporates UV disinfection and cargo monitoring functions, extending its role beyond temperature-controlled transportation. These capabilities combine physical refrigeration with digital monitoring and automated control, providing logistics operators with visibility into cargo conditions and refrigeration performance while the vehicle performs its assigned transport tasks.

Cloud Monitoring And Deployment Potential

Cloud-based monitoring is another key part of the vehicle’s operating system. The platform can track temperature, humidity, disinfection records, and refrigeration-unit status, while generating alerts for temperature anomalies and equipment faults. This creates a connected management layer around the refrigerated cargo operation and can help operators identify deviations or equipment problems during deployment. Combined with the L4 mapless driving capability, the Xiaozhu A6 Pro brings autonomous vehicle operation and cold-chain supervision into one integrated solution. Its planned deployment in multiple Yunnan locations will therefore provide a practical operating environment for autonomous refrigerated logistics beyond a single fixed route.
