Changan Tianshu Navigation ADAS Debuts With LiDAR, VLM and Driver Safety Features

China-based Changan Automobile unveiled its in-house developed driver assistance platform, Tianshu Navigation, during the 2026 Chongqing International Auto Show on June 13. The new system is designed to extend vehicle safety beyond conventional physical protection by integrating physiological, psychological and emotional safety layers. Offered in Pro, Max and Ultra variants, the platform targets different levels of intelligent driving capability while enhancing driver interaction, perception and response across diverse road environments.

Tianshu Navigation ADAS is engineered to improve both safety and convenience through advanced sensing, computing and artificial intelligence technologies. The company aims to deliver a more comprehensive protection system that addresses not only collision prevention but also driver well-being. By integrating intelligent decision-making with enhanced perception systems, the platform supports increasingly complex driving scenarios while laying the foundation for future autonomous driving functions in passenger vehicles.

Pro Version Enhances Hazard Detection in Low-Light Conditions

The Pro version comes with LiDAR as standard equipment across the lineup, enabling the system to identify obstacles up to two seconds earlier than the human eye during nighttime driving or while traveling through tunnels. Combined with the world-leading SDA central ring network architecture, the system improves response speed by 150 milliseconds. When traveling at 120 km/h under low-light conditions, the technology can detect hazards at least 60 meters earlier, allowing the vehicle to react before potential dangers escalate.

Max Version Improves Driving Efficiency Through Data Training

The Max version has been trained using more than 20 million high-quality human-driving data segments. This extensive training enables the system to improve traffic efficiency by 20% in common commuting situations. The enhanced capabilities cover congested roads, undulating terrain, extremely narrow residential areas, irregular intersections and blind-spot merging scenarios. These optimizations are intended to provide smoother and safer driving experiences in complex urban environments.

Ultra Version Introduces AI-Powered Interactive Assistance

The Ultra version utilizes a Vision-Language Model to strengthen environmental perception and support interactive driver-assistance functions. The system can learn and remember individual driving habits, enabling more personalized vehicle behavior over time. Future software upgrades are expected to add a driver incapacitation protection feature. If the system determines that the driver is incapacitated, the vehicle will safely move to the roadside and activate emergency measures to enhance occupant safety.

Changan Qiyuan Q06 to Receive Standard Tianshu Navigation

The upcoming Changan Qiyuan Q06 is scheduled for official launch in the second half of 2026 and will feature Tianshu Navigation as standard equipment across the entire lineup. The deployment reflects Changan Automobile's strategy to accelerate intelligent driving adoption and bring advanced safety technologies to a broader customer base. As competition in smart mobility intensifies, integrated ADAS platforms are becoming increasingly important in differentiating future passenger vehicles.
