Changan Auto Level 4 Robotaxi License Achieved for Full Scenario Testing

Emerging advancements in autonomous mobility reached a new milestone as Chongqing Changan Automobile Co Ltd secured a Level 4 robotaxi testing license, enabling real-world validation across all driving scenarios. This regulatory approval marks a critical transition from controlled testing environments to comprehensive on-road deployment, positioning the company among a limited group of automakers capable of executing full-scale Level 4 trials. The development also reflects the rapid evolution of intelligent driving technologies within China, where regulatory frameworks are increasingly supporting autonomous innovation.

Core to this achievement is the Tianshu intelligent end-to-end large model, which serves as the backbone of Changan’s Level 4 autonomous driving system. Built using extensive real-world data collected from mass-produced Level 2+ vehicles, the model integrates diverse driving scenarios, including complex urban and highway conditions. This data-driven approach ensures continuous refinement of perception, decision-making, and control systems, strengthening the robustness of autonomous performance. The integration of Level 4 autonomous driving capabilities with large-scale data analytics highlights a strategic shift toward scalable AI-driven mobility solutions.

Tianshu Model Enables Closed-Loop Development

The Tianshu system benefits from a structured development cycle that links testing, optimization, and feedback into a continuous loop. Data gathered from Level 2 and Level 3 vehicles plays a crucial role in enhancing algorithm accuracy and system responsiveness. This iterative framework allows engineers to simulate edge cases, validate responses, and deploy improvements rapidly, ensuring that the Level 4 solution evolves with real-world complexity. Such a closed-loop mechanism accelerates the maturity of autonomous systems while maintaining safety and reliability standards required for commercialization.

Strategic Integration Across NEV Sub-Brands

Technological advancements from the Tianshu-powered platform are being extended across Changan Auto’s new energy vehicle ecosystem, including its sub-brands Avatr, Deepal, and Nevo. These brands are positioned to leverage intelligent driving capabilities as a key differentiator in the competitive EV market. The integration of robotaxi testing license capabilities into commercial vehicle platforms signals a broader ambition to transition from pilot projects to scalable mobility services. This move aligns with industry trends emphasizing intelligent electrification and connected vehicle ecosystems.

Commercialization Path for Level 4 Mobility

With regulatory approval secured, Changan Auto is expected to accelerate its roadmap toward commercial deployment of robotaxi services. The company’s focus remains on refining system stability, enhancing user safety, and ensuring seamless integration with urban mobility infrastructure. Collaboration with ecosystem partners and continuous validation under diverse conditions will be essential for achieving large-scale adoption. As competition intensifies in the autonomous driving sector, the ability to translate testing success into viable commercial services will determine long-term leadership in the intelligent mobility landscape.
