Summary of Key Points
Huawei’s Qiankun Intelligent Driving system utilizes a “sensing redundancy design” that allows the vehicle to use multiple types of sensors (such as cameras and radars) simultaneously to monitor the road. Even if one sensor fails due to weather conditions or lighting issues, the others can compensate, enabling more accurate detection of obstacles, pedestrians, and other vehicles in complex driving situations, thus enhancing safety.
1. What is “sensing redundancy design,” and why is it necessary?
You can think of it as providing the vehicle with additional “eyes” and “ears.” Relying on a single sensor (like a camera) while driving can be problematic—for example, the camera might become blurred in rain, have poor visibility in low light, or be blinded by strong lights, making it difficult to detect pedestrians or other vehicles. A redundancy design involves installing several types of sensors with different functions: cameras for identifying shapes and colors, millimeter-wave radars for measuring distances and speeds, and lidar for 3D mapping. This way, if one sensor fails, the others can take over, ensuring the vehicle can always perceive its surroundings accurately.
2. How do multiple sensors work together to complement each other?
For instance, in foggy conditions, cameras may not be able to see anything, but millimeter-wave radars can still detect nearby vehicles and determine their speed. At night, cameras might not spot pedestrians, while lidar can identify small children crossing the road. The data from these sensors is integrated by the system, providing a more accurate assessment of the situation (e.g., “There is a pedestrian 50 meters ahead crossing the road; slow down.”)
3. What practical problems can this design solve in complex scenarios?
It addresses several common dangerous situations:
- Rainy/foggy weather: Radars can detect distances even when cameras are blurred.
- Dark residential streets: Lidar can quickly identify pets suddenly appearing in the road.
- Strong light: Millimeter-wave radars can function normally even when cameras are blinded by high beams, preventing collisions.
- Complex intersections: Multiple sensors can more quickly and accurately detect potential dangers (e.g., an electric vehicle running a red light), giving the vehicle enough time to brake.
4. What does this mean for us as ordinary drivers?
Simply put, it means safer and more hassle-free driving. Novice drivers no longer need to worry about complex road conditions, and experienced drivers can reduce the risk of accidents caused by sensor failures. For example, if a vehicle in front brakes suddenly on the highway, other sensors can alert you or apply automatic braking to avoid a collision. In the long run, this technology also makes autonomous driving more reliable, as it relies heavily on sensors, and redundancy design acts as a safety net.
5. What advantages does Huawei have in this area?
Huawei has expertise in communication and sensor technologies, such as 5G, which enables faster data transmission between sensors and enhances system integration. Its algorithms can process sensor data more effectively, ensuring the vehicle responds quickly and accurately. This is why Huawei emphasizes safety in its intelligent driving solutions; redundancy design is crucial for addressing safety issues in complex scenarios.
In summary, Huawei’s Qiankun Intelligent Driving’s sensing redundancy design uses a multi-layered approach to ensure the vehicle can see clearly under various adverse conditions, providing extra safety for both drivers and passengers. For consumers, this is an important factor to consider when purchasing intelligent driving features.
