Over the past year, several models under HarmonyOS Intelligent Driving, such as the high-end AITO M9 (priced over 500,000) and the best-selling AITO R7, have achieved remarkable market success, suggesting that every collaboration with Huawei seems to possess a certain "halo effect," consistently delivering surprisingly powerful products to consumers. What is Huawei's secret to achieving such remarkable success in the fiercely competitive automotive market?

Huawei's HarmonyOS Intelligent Driving Tech Day on December 23rd answered this question. The core lies in Huawei's consistently high R&D investment and its profound software, hardware, and data expertise accumulated over more than three decades in the Information and Communication Technology (ICT) field. These advantages are fully reflected in HarmonyOS Intelligent Driving products, solidifying Huawei's leading position in intelligent technology.

Wang Yanmin, President of Huawei's Smart Selection Vehicle Business Unit, pointed out at the Tech Day that Huawei has achieved comprehensive technological leadership in six major areas: intelligent driving, all-dimensional safety, intelligent cockpit, intelligent driving control, intelligent power, and intelligent connectivity. This allows HarmonyOS Intelligent Driving products to meet consumer needs for technology faster and better, laying a leading foundation for Huawei in the future intelligent electric vehicle market.

This HarmonyOS Intelligent Driving Tech Day focused on revealing Huawei's latest achievements in intelligent power and intelligent connectivity technologies. In intelligent power technology, the highlights include the DriveONE 800V high-low voltage common platform extended-range system, the Huawei Snowy Owl intelligent quiet extended-range system, and precise torque control technology.

Huawei is a pioneer in using the industry-leading 800V high-voltage enhanced system. Compared to the traditional 400V platform, the 800V high-voltage platform significantly reduces charging time. In HarmonyOS Intelligent Driving vehicles, combined with fast-charging batteries, it takes only 7.5 minutes to charge for a range of 250 kilometers, effectively alleviating range anxiety for users. The principle is similar to using a larger-diameter pipe to fill a water tank the water flows faster, and the tank fills up quicker. I personally experienced the high-speed charging on the AITO S7, adding 1 kilometer of range per second. Charging from 20% to 80% took only about ten minutes, making refueling efficiency almost comparable to gasoline vehicles.

Driven by Huawei's technology, the 800V high-voltage platform has become a key direction in the development of new energy vehicle power systems. Recently launched models from various industry companies now come standard with 800V high-voltage charging platforms. From an industry perspective, this technological direction further stimulates battery technology advancements. To meet the needs of 800V high-voltage fast charging, the development of high-rate charging batteries has become a priority, along with upgrades to the Battery Management System (BMS). Furthermore, the construction and upgrading of high-power charging stations are also necessary to adapt to the 800V high-voltage charging platform. Huawei's liquid-cooled super-charging stations are popular among new energy vehicle owners of various brands, which further drives the technological upgrading and market expansion of related components such as high-voltage components and circuit breakers. From this perspective, Huawei has become the chain master of the industry chain, demonstrating a significant chain extension effect.

Huawei's Snowy Owl intelligent quiet extended-range system provides a comprehensive solution to address the problems of poor fuel economy, high engine noise, large start-stop vibration, and unintelligent operation in traditional extended-range vehicles. The system uses four algorithms optimal power generation planning, vibration suppression, seamless power generation, and energy management to achieve super fuel efficiency. This technology debuted on the AITO R7 Extended Range version, achieving a fuel consumption of only 5.68 liters per 100 kilometers, reducing energy costs by 40% compared to traditional gasoline vehicles. For consumers, the Snowy Owl system intelligently controls the traditional range extender and various information, maximizing hardware capabilities and intelligently dynamically controlling power generation timing and electricity, improving fuel efficiency without requiring any effort from the user. Simultaneously, the systems quietness is significantly improved; starting, stopping, and operation are virtually imperceptible, with 99.5% of the journey as quiet as pure electric driving. Without looking at the energy display, its almost impossible to tell when the vehicle is using fuel or electricity. The overall quietness of the vehicle remains consistently high. For the industry, high-efficiency extended-range technology will move towards higher energy conversion efficiency, lower emissions, and more intelligent operational control.

The precision of torque control directly affects the vehicle's acceleration performance, handling stability, and ride comfort. Another highlight of Huawei's intelligent electric technology is the DVP distributed powertrain technology. This technology is like the perfect combination of the brain and limbs. Especially in scenarios such as high-speed obstacle avoidance or slippery roads, the DriveONE new generation of ultra-high-efficiency high-voltage powertrain, like the brain, sends instructions to each motor after detecting a slippery road, instructing them to use different forces to prevent vehicle loss of control caused by unidirectional force. According to reports, DVP technology can achieve emergency obstacle avoidance at a speed of 120 km/h, reducing the response time from 200ms to 80ms, more than doubling the speed. For consumers, this technology not only achieves a smaller turning radius, making U-turns and narrow parking easier, but also further improves safety factors in emergencies, giving drivers valuable reaction time. For the automotive industry, the advantages of distributed powertrain technology in key areas such as high-speed obstacle avoidance and tire blowout without loss of control will improve driving safety and may become an important part of future automotive safety standards. Furthermore, this technology can significantly improve the overall performance and energy utilization rate of electric vehicles, becoming another major advantage of new energy vehicles compared to traditional gasoline vehicles, and accelerating the industry's transition to electric vehicles.

HarmonyOS Intelligent Driving Tech Day: Huawei's Innate Advantages in Intelligent Connectivity Technology

Intelligent connectivity technology deeply integrates vehicles with the internet, cloud computing, and big data, enabling intelligent interaction between vehicles and the external environment, greatly improving vehicle safety, convenience, and comfort. This is precisely the greatest advantage of new energy vehicles over gasoline vehicles. Another major technological achievement revealed by Huawei at the HarmonyOS Intelligent Driving Tech Day HiFIN technology focuses on intelligent connectivity technology, forming the two wings of the new energy vehicle's take-off alongside intelligent power.

Huawei HiFIN technology, as the third-generation intelligent connectivity system, aims to address the challenges faced by traditional in-vehicle communication systems, providing a faster, more stable, and more intelligent network connection experience. The core capabilities of HiFIN technology include fast network reconnection, dual-SIM intelligent network selection X-SIM technology, and intelligent acceleration. These technologies can achieve second-level network reconnection, optimize network experience, and prioritize the transmission of high-priority services in weak network environments. Test results show that HiFIN technology performs far better than the industry average in weak signal environments, with a network recovery time of only 1.8 seconds, while competing models require more than ten seconds.

In Huawei's full-scenario strategy of "people-car-home," the car serves as a link between people and home, making the importance of its network connectivity self-evident. Leveraging Huawei's more than three decades of technical accumulation in the communications industry, Huawei has enhanced vehicle communication reliability through HiFIN technology. Even in weak signal scenarios such as underground garages and remote areas, vehicles can maintain signal connectivity to smoothly initiate basic vehicle functions such as remote control, navigation, and unlocking.
