As the center of intelligent interaction between people and vehicles, intelligent cockpit mainly covers the innovation and interaction in cockpit and cockpit electronics. It is a human-computer interaction system constructed from the perspective of consumer application scenarios.

Huawei takes "platform+ecology" as its development strategy, and provides more interaction for the intelligent cockpit through "HarmonyOS system car OS platform+HarmonyOS system car domain ecological platform+intelligent hardware platform", thus building a full-scene travel experience for people, cars and life.

At present, Huawei's HarmonyOS OS operating system has been installed on some models of Geely and BYD, and will be installed in the front of the vehicle as part of Huawei's intelligent cockpit solution. Brands that have cooperated with Huawei, such as Extreme Fox and Fairy World, are expected to be the first to load.

According to Huawei's layout in the field of intelligent cockpit, it is expected that Huawei will cut into the industrial chain of intelligent cockpit mainly as a Tier2 supplier in the future, thus generating more supporting opportunities. # Huawei HarmonyOS System #

Huawei's intelligent cockpit solution consists of computing platform, software platform, display platform and ecology.

The intelligent cockpit computing platform is Kirin vehicle module, and Kirin 7 10A has been used in glory series mobile phones. Based on Kirin chip of smart phone, IVI module is built to play the scale effect of industrial chain synergy and reduce hardware cost. In the future, it will become Huawei's first intelligent cockpit chip with manufacturing process 12nm and 8-core design, compared with Qualcomm 820A.

In terms of operating system, Huawei introduced HarmonyOS 2.0, which can achieve 10ms delay and 2.4Gbps throughput for mobile phones, smart wearable devices and automobiles. HarmonyOS 2.0 adopts advanced distributed capabilities to seamlessly connect life scenes from inside to outside the car.

The display platform includes car smart screen, AR-HUD and other hardware, and combines the capabilities of vision, sound effects and AI to create smarter cockpit hardware.

The ecological platform of the vehicle domain realizes the seamless connection of mobile phone+car +N terminal and realizes multi-functional interaction.

Huawei Intelligent Cockpit Solution:

HarmonyOS OS (which can be understood as a converged system) is an operating system independently developed by Huawei. Originally known as LiteOS, it was developed for the Internet of Things. Mainly used in Internet of Things, smart home, car networking, remote control, medical care and other fields. HarmonyOS system will be compatible with Linux, Unix and Android systems to achieve a seamless collaborative experience across terminals.

HarmonyOS OS is based on distributed architecture, which is natural and smooth, with safe kernel and ecology. HarmonyOS's operating system has a different starting point from Android and iOS. It is a brand-new distributed operating system based on microkernel and facing the whole scene, which can meet the requirements of smooth experience of the whole scene, reliable and safe architecture, seamless cooperation across terminals and multi-terminal deployment at one time.

* * Based on HarmonyOS OS, enjoy Huawei's "1+8+N" ecology and realize full inductive interconnection across terminals.

Compared with the traditional operating system, HarmonyOS car operating system is a real car-oriented operating system, which includes HMS-A(HMS for Automotive), 12 car subsystem and several HOS-C API, thus constructing a real car-oriented software platform.

HarmonyOS car OS software platform will be responsible for providing the underlying software system based on HarmonyOS OS operating system.

Huawei's HarmonyOS OS operating system adopts distributed architecture and modular design, which can combine and extract different modules to realize a combined intelligent operating system on different smart devices.

Based on HarmonyOS OS operating system, there is sharing and connection between cars and other intelligent terminals. A system can meet all kinds of hardware devices, connect people, cars and homes, and realize the real interconnection of everything.

There are more than 500 car control API interfaces in the car OS of HarmonyOS system, which can open the above functions and provide convenience for the subsequent development and customization of car companies, Tier 1 and other developers.

In the car ecosystem platform of HarmonyOS system, Huawei will cooperate with developers to provide more useful car applications and related hardware, and build an intelligent cockpit ecosystem through cooperation.

There are two main types of vehicle ecology: user-oriented application ecology and cockpit hardware ecology.

The application ecology is mainly developed jointly with more application software enterprises.

The hardware ecology faces more hardware equipment manufacturers, carries out interconnection, joint innovation and continuous upgrading, and then helps eco-partners to quickly develop software and hardware services that meet the needs of users and meet the differentiated characteristics of car companies' cockpits through opening API, bringing users the ultimate experience.

HI is the core brand of Huawei's smart auto parts business. The core of HI is to help car companies build cars with Huawei's inside model.

HiCar radiates the application service of the mobile phone to the car through the connection between the mobile phone and the car, and the mobile phone+car +N terminal is seamlessly connected to further enhance the human-computer interaction experience. It is estimated that the loading capacity in 202 1 year will reach 5 million units.

Huawei HiCar mainly provides two important opening capabilities.

One is the ability to access mobile phone applications and services, which can directly access virtualized automotive hardware resources through applications on mobile phones. Secondly, HiCar provides the open access capability of automotive hardware equipment. By integrating HiCarSDK, car engine and other hardware, HiCar can also be accessed quickly, and * * * can enjoy the rich application ecology and services of mobile phones, such as transmitting the content played on the mobile phone to the car. Finally, the seamless flow of mobile phones and automobile engines will be realized.

Under the trend of intelligence, Huawei has a leading technological advantage in the field of electrical intelligence, which can realize the service capability from components to full-stack services, and is expected to drive the industrial chain to speed up in an all-round way.

According to the White Paper on the Development Trend of Intelligent Cockpit jointly issued by roland berger and Horizon, the future development of intelligent cockpit will be divided into four stages.

The first stage is the integration stage of electronic information system, which is embodied in the transformation from subsystem to functional domain to realize the interconnection of various systems.

The second stage is to enhance the perception inside the car.

In the third stage, man-machine driving is realized, and the vehicle perception ability is further improved (voice control, gesture control, etc.). ), so as to realize the full cycle experience of consumers getting on-driving-getting off.

The fourth stage will build the final form of the intelligent cockpit and continuously enrich the scene from the perspective of user experience.

At present, the development of intelligent cockpit is in the first stage, and the development of domain controller has become the mainstream.

The future development of intelligent cockpit will be driven by both the demand side and the supply side. From the demand side, the deepening of consumers' awareness of electronic experience is in line with the trend of automobile consumption upgrading. From the supply side, the traditional cockpit is composed of independent and decentralized subsystems, which is difficult to form linkage and cannot meet the trend of consumer consumption upgrading. Therefore, the cockpit domain control mode is born in order to realize more functions and explore at the cost end.
