Changan Becomes First Client at China’s New Extreme-Traffic ADAS Simulation Lab
A new intelligent-driving laboratory that recreates extreme traffic and weather has entered service in Chongqing, giving automakers a controlled way to stress-test advanced driver-assistance systems at highway speeds.
Facility details
Reported by Car News China, China Merchants Testing Vehicle Technology Research Institute (CMVR) built the “three-in-one” center to combine full-vehicle testing, dynamic traffic scenarios, and simulated climate in one indoor site.
The lab covers about 5,000 square meters and supports test runs up to 130 km/h, according to China Central Television, which disclosed the project on February 11. The site began operations on February 9.
Engineers can dial in dense fog, torrential rain, and shifting light conditions to mimic dawn, dusk, glare, or overcast skies. CMVR general manager Fan Hailong said the fog system can continuously adjust visibility from roughly 10 meters to 1 kilometer within 30 minutes.
First client and use cases
Changan became the first automaker to book the facility, sending its Nevo A06 electric sedan for ADAS validation. The lab lets teams repeat dangerous edge cases, such as low-visibility cut-ins, sudden obstacles, and complex merges, without waiting for rare real-world conditions.
Why it matters
As Chinese brands race to ship more automated driving features, regulators and consumers are demanding proof that sensor suites and software behave safely beyond sunny, empty roads. By boosting repeatability and throughput, CMVR expects the center to shorten development cycles and improve the robustness of braking, lane-keeping, and hazard-detection functions across more vehicle programs.
