On the track of increasingly fierce competition in smart cars, Xiaomi Auto has quickly emerged with innovative technology and user experience. On October 28, 2024, Xiaomi Auto answered in detail questions about the precautions for winter use, the air purification function in the SU7, and the opening conditions of the CNOA City Pilot Assist Pioneer Edition in its 73rd episode of the Q&A. In this article, China Exportsemi will deeply analyze the core technology of Xiaomi's automotive CNOA system, its unique security measures, and how it can establish its own advantages in the industry trend.
1. Technical requirements and safety considerations for CNOA City Pilot Assistance
The opening conditions of the Xiaomi Auto CNOA City Pilot Assist Pioneer Edition are strict, reflecting the great importance it attaches to user safety. According to the official instructions of Xiaomi Auto, the use of CNOA requires the vehicle to be upgraded to the latest Xiaomi HyperOS 1.4.0 version, and the driver's Xiaomi Auto App account needs to reach 1000 kilometers of "safe intelligent driving mileage", and the learning course of the intelligent driving academy needs to be completed. This rigorous opening condition not only ensures the driver's familiarity with intelligent driving technology, but also sets a high threshold for the safety of the system.
Among them, the setting of safe intelligent driving mileage is very special. The logic behind this is to ensure that drivers have accumulated enough intelligent driving experience in their daily driving and are familiar with the different scenarios of autonomous driving assistance. The courses not only cover the basic operation guides, but also explain the driving skills of complex road conditions in detail, so that drivers can deal with different situations more confidently before activating the CNOA. This comprehensive safety mechanism demonstrates Xiaomi's dual guarantee of driving experience and safety.

2. In-depth analysis of the key technologies of CNOA: BEV and super-resolution occupancy network
The core technology of Xiaomi's CNOA system is reflected in its self-developed adaptive zoom BEV (bird's-eye view) technology and super-resolution occupancy network. These technologies not only improve security, but also greatly enhance the system's ability to identify and judge complex environments.
- Adaptive zoom BEV: In different driving scenarios, the CNOA system intelligently switches the angle of view through adaptive zoom, enabling the driver to monitor surrounding obstacles and dynamic information with a clearer view. Especially in high-speed and congested urban conditions, the advantages of BEVs are particularly obvious, which not only improves the adaptability of the system, but also reduces the operating burden on the driver.
- Super-resolution occupancy network: The highlight of this technology is that it can perform super-resolution recognition of roads, and achieve accurate perception of obstacles and road edges through more detailed calculations, even in complex weather conditions such as rain and snow. The combination of occupancy networks and high resolution allows the system to generate more granular decision support when receiving external data. This also means that the "mapless solution", which does not require mapping in a specific area, can handle complex driving scenarios in real time, laying the foundation for truly intelligent driving in the future.
3. SU7 Air Purification System: A New Highlight for the User Experience
In addition to the intelligent driving technology, the air purification function in the Xiaomi SU7 car is also worth paying attention to. SU7 is equipped with PM2.5 real-time monitoring system, CN95 filter, AQS air quality detection system and antibacterial evaporator as standard, which fully guarantees the cleanliness of the air in the car. In addition, the SU7 is also designed with an intelligent unlocking ventilation function, which allows the vehicle to automatically open the external circulation when unlocked, further improving air quality.
Xiaomi's air purification function not only focuses on health, but also pays more attention to the optimization of details for daily use. For example, in response to the common problem of trapped air in the car during winter driving, the system is able to automatically filter pollutants through intelligent adjustments. This humanized design gives Xiaomi Auto a significant competitive advantage in terms of user experience.
4. Market positioning and the brand competitiveness of Xiaomi Auto
Xiaomi Auto accurately targets the mid-to-high-end market of more than 200,000 yuan, focusing on young consumer groups. Behind this market positioning is the transformation of consumer demand from basic means of transportation to personalized and intelligent products. With the increasing application of AI and IoT technologies in in-car scenarios, the positioning of smart cars is gradually changing to "mobile living space", and Xiaomi Auto is aiming at this transformation opportunity.
In terms of brand influence, Xiaomi's ecological chain has injected unique brand value into its smart cars. For example, Xiaomi already has a large user base for mobile phones and IoT devices, which brings a natural user base to Xiaomi Auto. At the same time, Xiaomi's investment in autonomous driving technology cannot be ignored - including investment in autonomous driving companies such as Momenta and Zongmu Technology. This kind of advanced technical layout will undoubtedly become an important support for it in the intelligent driving market.
5. The future layout of Xiaomi cars and the potential of intelligent driving
From the perspective of technical strength, Xiaomi Auto's in-depth research and development in the field of intelligent driving has laid its unique competitiveness. In the case of CNOA, for example, its zero-takeover design ensures that drivers can enjoy safety even when driving for long periods of time, and the NOA opening target in 100 cities is a sign of Xiaomi's ambition to widely popularize autonomous driving in the next few years.
The forward-looking nature of Xiaomi Auto is reflected in its commitment to not only meeting the current market demand, but also making breakthroughs in future technologies. For example, Xiaomi plans to achieve self-optimization through continuous improvement of AI algorithms, sensor systems, etc., and continuously improve the system's ability to cope with complex environments. Considering the rapid development of intelligent driving on a global scale, this continuous improvement of the technical route will occupy a place for Xiaomi cars in the market.
6. Industry competition and challenges of Xiaomi Automobile
Although Xiaomi has advantages in intelligence, it cannot ignore the fierce competition within the industry. Especially in the field of autonomous driving and intelligent cockpits, both traditional and new car companies have invested a lot of resources. Xiaomi's success in the future largely depends on its continuous investment in technology research and development and its differentiated positioning in the market.
Xiaomi's advantage lies in the integration of the ecological chain and brand appeal, but the challenges are also obvious - traditional car companies have accumulated deep experience in technology and manufacturing, and new forces such as NIO and Li have also launched upgraded solutions in intelligent driving. In such a competitive environment, Xiaomi's CNOA system needs to be quickly iterated and continuously optimized to maintain its technological and market competitiveness.
7. Conclusion
The launch of the CNOA City Pilot Assist Pioneer Edition not only demonstrates its technical strength in the field of intelligent driving, but also represents Xiaomi's comprehensive improvement in safety and user experience. With strong brand appeal and accurate market positioning, the development of Xiaomi Auto in the future intelligent market is worth looking forward to. As Xiaomi further deepens its layout in the fields of intelligent driving, intelligent cockpit and other technologies, the innovation ability and market potential of Xiaomi cars will gradually emerge. Driven by the continuous progress of technology and market demand, Xiaomi Auto may create a new situation in the field of intelligent driving.
