Changan Auto Unveils Advanced Driving Assistance System "Tianshu Navigation" and Digital-Physical Integrated Autonomous Test Track

Recently, Changan Automobile officially launched its self-developed advanced driver assistance system, Tianshu Navigation. The accompanying vehicle-road-cloud integrated digital-physical fusion unmanned test facility made its public debut for the first time. Led by Changan Automobile and co-developed with partners including Black Sesame Smart and China Intelligent Vehicle Innovation Center (CIIC), the test facility supports mass-production safety validation of the Tianshu Navigation system. It enables iterative verification of advanced driver assistance functions for both the Changan Tianshu Navigation system and the Qiyuan Q06 production model, focusing on standardized, unmanned testing under extreme intelligent driving conditions and high-risk scenarios. The facility bridges digital simulation and physical real-world testing into a closed-loop system, establishing an integrated digital-physical workflow covering test task orchestration, real-vehicle execution, and data re-injection. Black Sesame Smart provides chip-based computing power for the roadside edge computing units and camera systems within the test facility. Its solutions support comprehensive object recognition across the entire test area, intrusion warnings, ground-truth output for high-precision positioning, and automated sensor calibration. Additionally, it delivers essential computing capabilities for multi-source heterogeneous data analysis, multimodal perception fusion, and real-time edge computing.
