On November 9, Huawei officially launched the first car smart S7 of Huawei's smart car business in Shenzhen, which is a high-energy, large-space smart car jointly created by Huawei and Chery. The production of a new platform built by Huawei's full-stack smart car solution will bring a new full-scene intelligent travel experience for users in the car market.

On November 10, after the release of the new Smart World S7, Huawei held another media conference on Huawei Smart Travel Technology in Shenzhen. Wang Yanyi, president of Huawei Terminal Free car Business, Li Yu, technical expert of Huawei Intelligent cockpit product line, and other senior executives attended the meeting to share with us the technical details related to the HarmonyOS intelligent cockpit, HUAWEI SOUND 2.0 and HUAWEI DriveONE intelligent electric drive platform behind Huawei Smart World S7.

The first is the HarmonyOS intelligent cockpit, which is committed to innovating the way of human-vehicle interaction. The operating system adopts distributed architecture, modular combination design, soft bus data transmission and sharing, and self-research and optimization from vehicle-machine module, frame layer and system service layer, so that the rapid interconnection between various intelligent terminals can be realized and the application ecology can be shared among multiple intelligent devices.

At the communication meeting, Wang Yanyi, president of Huawei's terminal optional car business, focused on the characteristics of HarmonyOS intelligent cockpit in four aspects: fluency, intelligent interaction, safety and common use.

In terms of fluency, the HarmonyOS intelligent cockpit has been fully upgraded through the Ark engine, achieving a significant improvement in graphics, multimedia, memory, scheduling, storage, low power consumption and other capabilities. At the same time, it has a minimalist interface, customized design of human factor research based on driving scene, so that most of the settings and information can be accessed in one step, and the dynamic effect of this word also makes the operation more comfortable. Generally speaking, the HarmonyOS intelligent cockpit realizes the ultimate fluency experience of smooth human-car interaction, smooth voice interaction, smooth map control, fast application startup, multi-task parallel fluency and leading multimedia performance.

In terms of safety, Wang Yanyi first took the statistics of the black screen complaint rate of the vehicle quality net in 2022 as an example:

It can be seen that the current user black screen complaint rate of a car company in front of a vehicle is as high as 39.2%, while M5 has not received user feedback from the black screen since its release.

Wang Yanyi said that in order to create a non-black screen for the entire car, Huawei has two core key technologies. One is a chip-level independent reliability system, which can detect the potential stability or reliability risk of the entertainment domain and instrument domain in real time. Thus through 100% coverage detection and rapid self-recovery in time, to achieve second recovery.

The other is the highly reliable Hongmeng kernel, which can achieve no access, the service is relatively isolated, the fault between kernel services does not spread, and if there is a service exception, it can achieve self-recovery of the service. At the same time, Hongmeng kernel has successfully passed the first CC EAL6 + highest-level certification in the field of commercial OS in the industry.

Next, Dr. Wu Sheng, an expert in intelligent cockpit audio technology of Huawei, introduced the application of HUAWEI SOUND technology in intelligent travel solutions.

Wu Sheng said that car audio is a complex system engineering, traditional audio manufacturers often only have their own unique advantages in one or two aspects, while entering the digital age requires audio manufacturers to have full-link technology reserves, in this regard, Huawei also has an industry leading edge.

For example, HUAWEI SOUND 2.0 relies on Huawei's industry-leading unique algorithm, new high-end brand logo, hall-level sound quality, 7.1.4 immersive sound field, super-telepresence space audio, intelligent sound field control, and millions of high-quality sound sources to create a real end-to-end top audio and video experience for car owners.

Wu Sheng focused on the design of star-ring scatterers integrating light and shadow aesthetics, acoustic technology and AI wisdom, which is the first time that Schroeder acoustics technology has been on board, which can not only make users in the cockpit feel the intelligent emotional interaction experience of light and shadow moving with sound, create a glowing dynamic cockpit atmosphere, but also achieve the consistency of the whole car's hearing.

In addition, in terms of space audio, Huawei space audio provides complete services based on the ecological advantages of content sources, car operating systems and audio equipment, and the software and hardware deeply adjust the immersion listening effect that can give full play to the advantages of the cockpit. Compared with the traditional car audio, it can virtual reconstruct the spherical space and let the sound linger around the user in all directions.

Finally, Dr. Lin Junhai, an expert on Huawei DriveONE high-voltage powertrain, shared with us the technology of the new high-voltage powertrain platform of DriveONE, the intelligent electric product line.

Lin Junhai said that after so many years of development, Huawei's smart electric business has basically formed two major platforms for pure electric and hybrid models. Huawei has defined a series of power domain solutions based on these two platforms, and its main advantages include five aspects.

First of all, the world's highest speed electric drive, supporting 800V high voltage platform brings excellent power, HUAWEI DriveONE intelligent electric drive platform uses a world-class front AC asynchronous motor + rear permanent magnet synchronous motor SiC high voltage four-wheel drive combination, dual motor maximum power up to 430kW (front motor 180kW, rear motor 250kW), can bring users stronger power, lower energy consumption, more quiet driving experience.

The second is ultra-low energy consumption. Huawei has improved the MCU efficiency by more than 99.5% through the new self-developed SIC module, ranking first in the industry, effectively supporting the assembly motor efficiency by 97.8%, far exceeding that of its competitors.

In addition, the HUAWEI DriveONE intelligent electric drive platform uses the industry-leading intelligent oil cooling 2.0 technology, compared with the water cooling technology commonly used in the industry, the cooling effect of key components is significantly improved under the same power and torque.

In the aspect of quiet driving, around the vehicle NVH performance index, Huawei uses the self-developed AI multi-objective optimization tool chain to carry out the overall global optimization design, and through the multi-physical field coupling AI simulation of the shell / cover plate / tooth shaft and other parts, the excellent static performance of the whole vehicle NVH ≤ 78dB is finally achieved.

Finally, the safety and reliability of the whole vehicle. Huawei integrates the data from the design / verification stage and the manufacturing stage to the whole life cycle data from the consumer use and maintenance stage to form a larger database. at the same time, the generalized industrial target detection pre-training model based on Pangu model + machine vision and sensor technology makes the manufacturing process coverage 80% +. Can achieve "100%" defect detection rate, μ m-level assembly accuracy, through such innovation to ensure that the products delivered to the hands of consumers are highly consistent and the quality is the best.

As of November 13, the pre-booked quantity of the S7 has exceeded 10, 000 units, which can be said to be hot. Behind this, it undoubtedly reflects consumers' recognition of Huawei's smart travel solution. Through this technology exchange meeting, we have a further understanding of the advantages and leadership of Huawei's smart travel solutions. they have the ability of "smart ceiling" in the four major areas of intelligent cockpit, intelligent driving, intelligent vehicle control and intelligent network connection, and learn from others in product design. Deeply integrate the consumer electronics industry with the automotive industry, from the perspective of comprehensive perception of seeing, touching, listening and sniffing. Bring users more comfortable, smarter and safer products.
