🛠️ Technical Deep Dive
- Changan's 'Tian-Shu' intelligent driving system integrates core technologies across driving, cockpit, and chassis, including end-to-end navigation, multimodal AI models, distributed electric drive, and wire-controlled chassis.
- The system achieves four-wheel independent control, with drive and brake response times of 10ms, reducing hydroplaning risks by 76% and correcting trajectories within 0.1 seconds during a tire blowout.
- The L3 system utilizes a sensor suite comprising 5 millimeter-wave radars, 6 cameras, and 12 ultrasonic radars, providing 360-degree external environment perception with 5-fold sensing redundancy in the front.
- It boasts a maximum detection distance exceeding 200 meters and a measurement accuracy of up to 10 centimeters, capable of identifying vehicles, pedestrians, cyclists, and other obstacles.
- The system can acquire road information within an 8-kilometer range in real-time, enabling lane-level high-precision positioning and precise path planning.
- Changan plans to enhance its perception capabilities by upgrading its self-developed satellite-architecture LiDAR to over 200 lines and tripling computing power by Q3 2026, while simultaneously aiming for a 30% cost reduction compared to peers.
- The L4 Robotaxi solution is built upon the core Tian-Shu end-to-end large model, sharing the same underlying algorithm architecture with its mass-produced L2 and L3 models to ensure technological homology and scalability.
🔮 Future ImplicationsAI analysis grounded in cited sources
Changan Auto is strategically positioning itself as a leader in both mass-market L3 and advanced L4 autonomous driving in China.
By securing both L3 operational permits and L4 Robotaxi testing licenses, and emphasizing a "dual-track" development, Changan aims to gather data and user feedback from L3 while validating L4 for future mobility services.
The denial of partnership with Qianli Technology reinforces Changan's commitment to its proprietary 'Tian-Shu' system and in-house R&D.
Changan has heavily invested in its self-developed intelligent driving system and talent pool, indicating a preference for internal control over core autonomous driving technology rather than relying on external solutions from companies like Qianli.
Competition in China's autonomous driving market will intensify, with a strong focus on L3 commercialization and rapid L4 development.
Multiple Chinese automakers and tech companies are rapidly advancing L3 and L4 solutions, with regulatory approvals paving the way for wider deployment and market differentiation, leading to a highly competitive landscape.
