Huawei Qiankun Unveils CAS 5.0 with Sixth Dimension: "All-Time Safety Target"

Huawei's Qiankun Intelligent Automotive Solution recently provided a detailed overview of its Comprehensive Anti-Collision System (CAS) 5.0, which upgrades the original five-dimensional safety framework to six dimensions by introducing an additional "all-time-domain safety objective" on par with active and passive safety. This new dimension leverages Safety Risk Field technology, enabling vehicles to achieve end-to-end safety capabilities—from proactive prevention to post-incident protection. In low-speed scenarios, traditional systems are prone to collisions due to limited braking redundancy and potential delays in perception or decision-making. CAS 5.0 addresses this by adding a forward-facing high-precision solid-state LiDAR, significantly improving close-range obstacle detection accuracy. As a result, the minimum activation speed for Forward Automatic Emergency Braking (AEB) has been reduced from 4 km/h to 1 km/h. Additionally, by optimizing the sensor fusion algorithm with extensive real-world scenario data, the system lowers the operational speed threshold for Lateral Obstacle Collision Prevention (LOCP) from 30 km/h to 10 km/h while also reducing false trigger rates. Furthermore, the system integrates an upgraded eAES 3.0 (enhanced Active Emergency Steering) function that extends protection coverage to the vehicle’s rear-side areas. It can detect and respond to cut-ins or aggressive lane changes from vehicles approaching from the side-rear, executing timely evasive maneuvers. Under specific conditions—such as when a fast-approaching vehicle is detected directly behind and no vehicle is present ahead—the system can proactively accelerate the vehicle forward to avoid a rear-end collision, thereby expanding its capability from “avoiding hitting others” to “avoiding being hit by others.”
