From April 18 to 27, 2023, the 20th Shanghai International Automobile Industry Exhibition was held in the National Convention and Exhibition Center (Shanghai), showing the new look of technology leading the automobile industry to change in a new era. At the exhibition, China Mobile focused on the ToV market’s "car, road, network, cloud and map" capabilities, showing its core advantages and important achievements in the fields of intelligent networking, intelligent cockpit and intelligent driving, which attracted a lot of attention. With the theme of "Go all out to go out with blood", China Mobile held an expedition ceremony for the car networking corps, and awarded military orders and flags to 14 teams and provinces, marking the official expedition of the car networking corps of China Mobile.

Intelligent networking: building a secure cloud and a powerful network

The intelligent networked system based on secure cloud and powerful network provides basic guarantee for intelligent networked vehicles. Relying on mobile cloud’s ability, China Mobile has realized the "N-31-X" resource layout, provided professional cloud services with integrated cloud and network, and supported the business needs of various scenarios in the automobile industry. "Mobile Cloud creates safe, compliant, stable and reliable cloud infrastructure services and capabilities, builds a car enterprise cloud and an autonomous driving cloud for the whole life cycle of automobiles, and provides unified data and analysis for car companies and autonomous driving R&D enterprises."

Relying on 5G cellular network, high-precision positioning network and vehicle-road collaborative network, China Mobile has realized the basic capabilities of communication and calculation, high-precision positioning and mapping, and integrated perception and information interaction. At the same time, using the edge computing power of 5G, it provides information services for self-driving vehicles of different grades.

A strong network cannot be separated from the support of computing power. Faced with the higher demand for secure and reliable connection and computing power network in the field of intelligent network connection, China Mobile takes advantage of 5G-edge computing to meet the demand of secure and reliable connection and low-delay computing power supply, and builds a highly reliable collaborative computing network application.

Intelligent cockpit: deep integration of infotainment and intelligent service

"Know Your Car" is the highlight of China Mobile’s participation in this exhibition. The information and entertainment sharing product of "People and Car Home" debuted for the first time. Through the capacity base of China Mobile’s OneTraffic platform, it provided four capabilities: unified mall operation, "People and Car Home" integrated operation, ecological aggregation service and refined service operation, which met the needs of car companies such as content services, car owners’ traffic renewal service and car rights subscription.

"This is a car-end product that combines the capabilities of China Mobile’s own products. It applies the unified account capability and self-owned content product capability of China Mobile to the car-end, and creates car owners’ service products through high-frequency usage scenarios such as refueling and traffic recharge." According to the on-site staff, the product can quickly identify the owner’s personal network information through the identification of the Internet of Things card-real name interface; Users can use a small phone bill to pay for the traffic products in the car and get through the consumption behavior of people and cars. The audio and video rights purchased in the car can be shared on the mobile phone.

The Miguyuan Cosmic Intelligent Cockpit is another eye-catching exhibition. China Mobile, through technologies such as 5G﹢AI﹢XR, has joined hands with many car companies to build a Meta-Cosmic Intelligent Cockpit, which provides users with a one-stop entertainment service of "listening, singing, watching and playing".

Intelligent driving: high-precision "map" and intelligent "road" escort safety

China Mobile has deployed and tested indoor Beidou positioning equipment in several tunnels and venues, and achieved seamless outdoor lane-level navigation, accurate navigation in tunnels and continuous indoor and outdoor navigation, which is forming a leading space-time information capability in the industry.

"China Mobile’s joint partner tackled technical problems such as seamless connection and positioning of indoor and outdoor Beidou, and obtained more than 10 patents, creating the first indoor and outdoor continuous high-precision positioning based on Beidou." On-site staff told reporters that China Mobile’s self-developed indoor Beidou base station, terminals and other equipment can regenerate Beidou satellite signals in indoor scenes, which can provide accurate positioning and navigation indoors and provide accurate location services for intelligent driving in tunnels, parking lots and other scenes.

Smart intersection is the junction of smart cars and smart cities, and it is also an important edge node for future vehicle-road coordination. Vehicle-road coordination, scene verification and commercialization of autonomous driving all need to rely on intersections to achieve landing, which is an important node of "facing the future and compatible with the present".

"The smart intersection platform relies on the operator’s edge cloud, 5G and C-V2X converged networking capabilities to gather multi-source sensing data at the intersection and provide low-latency dual-channel information services for vehicles." On-site staff introduced relevant applications to reporters, including security, efficiency improvement, information service and traffic management.

At the Shanghai Auto Show, there were many highlights in the China Mobile Exhibition Area. "In the future, China Mobile will seize the strategic opportunity of building a transportation power, a network power and a digital China, integrate superior resource capabilities such as network, cloud and map, focus on breaking through core technologies, make full efforts to seize strategic highlands, and accelerate to become the first provider of market information services."

　　[Aika car SUV channel original]

　　Roewe RX5′ s monthly sales of 20,000 units can be said to have earned enough profits and eyeballs for SAIC. It must be said that SAIC’s accumulation in styling design in recent years has brought exquisite appearance to RX5, and another group of young people in the same R&D center have also created many topics for RX5 human-computer interaction system with their unique ideas. What kind of world is hidden under such a car that shines brightly?

　　The vehicle we shot this time is Roewe RX5 20T two-wheel drive Internet Smart Edition, equipped with a 1.5L turbocharged engine and a 7-speed dual-clutch gearbox, driven by front wheel drive.

I. Overview of Chassis

　　Similar to the chassis structure of many compact SUVs on the market, RX5 adopts McPherson independent front suspension and E-type multi-link independent rear suspension. The chassis of RX5 has no redundant guard plate to protect the parts, from which we can also see that it focuses on the positioning of urban road conditions. However, through analysis, we can still find that RX5 is worthy of its price and people’s attention in chassis structure and materials.

　　RX5 adopts a frame-type front subframe, which can not only improve the overall strength of the front of the car body, but also make the force on the front of the car body more uniform.

　　RX5′ s two-wheel drive vehicle adopts a rear subframe similar to H-shape, and almost all the connecting rods on the rear suspension apply force to the rear subframe, thus reducing the direct impact of suspension on the vehicle body. The rear subframe of RX5 four-wheel drive vehicle is structurally different from that of two-wheel drive vehicle.

Second, the front suspension analysis

　　RX5′ s McPherson independent front suspension is really nothing too surprising. Indeed, for most cars under 200,000 yuan on the market, it is too ordinary to adopt McPherson front suspension. However, the details of the RX5 front suspension still have its own special features.

　　On the whole, the front suspension adjustment of RX5 tends to be comfortable, and the damping spring can filter out most small vibrations, but for some relatively large vibrations, the response of the spring is a bit stiff. Usually, the relatively large vibration will be directly transmitted to the car, which makes people somewhat unprepared. However, thanks to this adjustment, RX5 has a good performance in controlling roll.

Third, the rear suspension analysis

　　RX5 adopts E-type multi-link independent rear suspension, which is also quite common in the same class. This multi-link suspension adopts a vertical and three horizontal conventional structure, and most of the connecting rods are stamped from steel plates, and there is not much innovation in the arrangement of connecting rods.

　

Although the TOP3 of vehicle sales has become a repair field for Tesla and BYD, don’t forget that there is an old six who has been a big brother for a long time. This is Wuling, which ranked sixth in sales last month. However, this model may encounter a little trouble, which is the long-life version just listed.

Judging from the Pentium Pony Long Life Edition, its biggest change is the introduction of two CTLC models with a cruising range of 222 kilometers, which means that the cruising range has changed from the original maximum of 170 kilometers to 222 kilometers. This is more advantageous than the classic Hongguang MINIEV.

The current pattern is that the two models newly listed by Pentium Pony have a battery life of 222 kilometers, and the prices are 36,900 yuan and 39,900 yuan respectively. The Hongguang MINIEV classic with a battery life of 170 kilometers is still the 2022 enjoyment of 44,800. Of course, Hongguang MINIEV also has a longer battery life, but the starting price has reached 55,800 yuan, and the battery life is also 200 kilometers. If you want to go further, the official guide price of MINIEV GAMEBOY’s fun money and coffee money is almost 70,000 yuan, which is completely different from the Pentium Pony Long Life Edition.

Looking at Hongguang MINIEV from Pentium pony, the idea of Pentium pony is lower threshold and higher cost performance. Pentium pony has set the minimum allocation to early 20 thousand, to be honest, this is already in the bright market to grab the old man’s music. At the beginning, the idea of Hongguang MINIEV was to share a piece of the low-speed electric vehicle market, so as to change the pattern of the old man music market with higher security. Therefore, the more neutral design makes the rich and the poor fondle admiringly.

However, it seems that the Pentium pony is not well understood, and it has a lovely appearance, which is obviously more focused on this part of the young people market with limited consumption. We are going to talk about this topic in the next article.

Of course, the Pentium pony also has many remarkable places. For example, safety, at such a low price, it can provide you with high-strength anti-collision beams, especially those two airbags, which is already a gift. You know, many vans at the same price and Hongguang MINIEV classic models will not give you these. What’s more, Pentium Pony started to produce cars according to the standards of cars. You can laugh at its small wheels and small space, but only if you compare it with whom and how.

After figuring out these problems, you will find that Pentium pony is more worry-free and easier than electric motorcycles. Its seemingly limited battery life can not only meet your daily commuting needs, but also the travel cost per kilometer is only a few cents, which can be said to be cheaper than crowded buses. Because of this, Pentium pony can continuously achieve monthly sales of over 10,000. After the increase in battery life, there is a trend of reducing the dimension of the classic MINIEV. When the scooter market is facing new changes, can the Pentium Pony Long Life Edition surpass Wuling Hongguang MINIEV to become a new market leader?

Middle-aged people tend to be more interested in sedate models. The atmospheric design and exquisite interior are the characteristics of such models, which are excellent choices for going to work or picking up children. The song L DM-i we are talking about today. Let’s take a good look at it.

Let’s take a look at the appearance of Song L DM-i first. The front face of Song L DM-i looks very dynamic and lively, and it looks very round. At the same time, the headlight presents an elegant design style and the visual effect is good. The car is equipped with LED daytime running lights, automatic opening and closing, adaptive far and near light, delayed closing and so on. Coming to the side of the car, the body size of the car is 4780MM*1898MM*1670MM. The car adopts young lines, and the side wall feels very sporty. With large-sized thick-walled tires, smooth lines run through the whole side of the car. Looking back, the rear of the car echoes the front face, and the taillight style is more elegant, creating a good gas field.

Coming into the car, the interior of Song L DM-i enhances the visual coolness, which makes people feel very cool. The steering wheel of the car is very unique in shape, made of leather, and everything looks very tough. Let’s take a look at the central control, with a 15.6-inch central control screen, which makes the interior style impressive. The overall design of the central control is very good. Let Xiaobian introduce the dashboard and seats. The dashboard of this car presents a simple design style and looks very solid. The car uses leather seats, equipped with functions such as electric adjustment of auxiliary seats, electric adjustment of seats, and seat proportion tilting, and the overall comfort and wrapping are not bad.

Song L DM-i’s back row space is still spacious, and there is a certain margin in the head and legs, which can be said to be more than enough for daily use. In addition, the car is equipped with fatigue warning, anti-lock braking (ABS), LED daytime running lights, brake assist (EBA/BAS, etc.), brake force distribution (EBD) main driver airbag, co-pilot airbag, side airbag curtain, front side airbag and other safety configurations.

Summary of the full text: This car has been introduced almost before, and I believe many users who buy a car have taken a fancy to its comfort and practicality.

Editor in charge:

Today we brought this car. So whether this car is a mule or a horse, let’s take a look at its actual performance.

Let’s take a look at the appearance of ZEEKR 001. The front face of ZEEKR 001 is very fashionable and recognizable. Combined with sharp headlights, it outlines a cool effect. The car is equipped with LED daytime running lights, automatic opening and closing, adaptive far and near light, delayed closing and so on. Coming to the side of the car body, the size of the car body is 4977MM*1999MM*1533MM. The car adopts unique lines, and the side of the car presents a domineering and stylish design style. With large-sized thick-walled tires, it gives people a very sharp feeling.

speed up apply the brakes oil consumption second rice rise Rejuvenation overnight: a test of Buick Angkewei s two-wheel drive Evaluation Editor-Li Qiaochen:

After the overall rejuvenation of Buick Angkewei S, the whole car naturally becomes more lively. Compared with the cash, Angkor simply can’t see any inheritance relationship between the two. The driver-led style of the interior also shows that Buick designers just want to build a medium-sized SUV model that is no longer old-fashioned. The dynamic performance is very surprising, and the adjustment of the chassis is somewhat sporty. With sufficient power reserve, the power output can always keep up with your driving rhythm.

Evaluation editor:

Buick has gradually become younger in recent years, and this Angkor S is no exception. The shape of a medium-sized SUV can be made so low, and even the illusion of a station wagon appears, which is a change of Angkewei’s mature and stable image. Although it is mainly two-wheel drive, the driving experience in the city has little effect. The light and even slightly sensitive throttle and solid chassis will definitely make people who love driving fall in love with this SUV.

Evaluation Editor-Hong Bingqing:

As can be seen from the appearance design, this is a "non-mainstream" SUV, and it is a farewell to Buick in everyone’s inherent thinking. The exterior decoration of this sports model is in place, but it is not out of line. The interior did not stick to stereotypes, and it was very bold to play a driver-centered design. Since it is mainly a two-wheel drive model, the more sporty driving style of Angkewei S becomes reasonable. It is a medium-sized SUV, but driving it in the city will not be boring.

[Original Truck House] can be said to be the most familiar strange truck parts for card friends. As we all know, the air filter can purify the air entering the air, so most card friends are very happy to replace the air filter in time, but the air filter is not changed as often as possible.

What problems will the frequent replacement of air filter cause to the engine? Can the air filter be used for scrapping and then replaced? Today, we will simply discuss these issues with card friends.

Air filtration, that is, it consists of two parts: filter element and casing. The filter element is the main accessory, which plays the role of gas filtration, and the casing is the shell that provides protection for the filter element. The main function of air filter is to filter the air entering the engine and purify the air quality.

The air contains a lot of impurities, such as dust and sand. If it directly enters the engine chamber without purification, it will accelerate the wear of the engine and even cause the phenomenon of "cylinder pulling". The air that enters the engine after being filtered by the air filter is relatively clean and can delay the occurrence of these problems.

As a kind of filtering device, the air filter is insignificant, but it has a light position compared with engines and other accessories. If the air filter is not filtered, natural air will directly enter the engine working room, which will lead to engine wear. If the air filter is not maintained for a long time, the filter element will be covered with dust, which will hinder air circulation and make the engine work abnormally.

The serious blockage of air filter will increase the intake resistance, which will lead to the decrease of engine power. At the same time, because of the increase of air resistance, it will also increase the fuel consumption when the engine is working, which will worsen the engine running state and increase fuel consumption. Therefore, ordinary card friends also need to maintain the filter element of air filter.

Since the role of air filter is so important, and if it is not maintained in time, it will also cause problems such as increased engine fuel consumption and decreased engine power, so can the filter element be replaced frequently? So that the engine can always be in the best working condition? The answer is no.

In addition to filtering the air, the air filter is also responsible for the air intake required by the engine. Inferior filter element, in order to reduce the cost, the quality of the materials used will be poor, which will lead to too large or too small air intake, and even fail to play a filtering role, which will directly lead to abnormal wear and tear of the engine.

So how about changing the air filter that meets the standard frequently? In order to play a good filtering role, the air filter element will have a large number of irregular gaps on the surface of its filter paper, but dust, sand, etc. are also large and small, so it is impossible to become completely pure air after being filtered by the filter element, and it will still contain some impurities.

In order to distinguish the filtration degree of the filter element, the concept of "initial interception efficiency" is introduced, which is usually expressed by percentage (%). If the initial interception efficiency is 99.95%, it means that the filter element can filter out 99.95% impurities in the air at the initial work, but 0.05% impurities cannot be filtered out, which will enter the engine with the filtered air.

Corresponding to the initial interception efficiency, there is also a "life cycle efficiency", which is also expressed by percentage (%). As the filter is used for a long time, the dust accumulated on the surface of the filter paper will gradually increase, which will block the gap between some filter paper fibers, which means that the pores between fibers become smaller, and the interception efficiency of the filter element will increase compared with the initial state.

So which interception efficiency is more advantageous, the initial interception efficiency or the whole life efficiency? An experiment was conducted in Truck House. The initial interception efficiency of an air filter can reach 99.81%, while its whole life efficiency can reach 99.98%. The difference between the two filtering effects is about 9.5 times.

That is to say, if the new air filter is used to enter the air in the engine, the impurities in it will be 9.5 times more than those in the air in the old air filter. Before, we have learned what harm will be caused to the engine by more air impurities entering the engine, so this is also the reason why the air filter element cannot be replaced frequently.

For the air filter, you can’t change it frequently, and you can’t always use a new air filter, and you can’t always change it, so you can’t get the filtering effect. So when is the best time to change the air filter?

Under normal circumstances, the effective service life of general air filters is about 20,000-30,000 kilometers, but the service life of air filters will be different due to the actual working conditions of the car and the engine, which will be mentioned in the maintenance manual attached to the car. Card friends can choose to maintain or replace the air filter at a suitable mileage according to their own situation.

● 　Postscript

Although the air filter is unremarkable, it plays an important role. It can’t be replaced with a new filter frequently, and it can’t be replaced all the time. When the card friends maintain and replace their models, it is best to follow the manufacturer’s maintenance manual, or according to the advice of the technicians in the maintenance station, so as not to cause immeasurable damage to the start.

This article comes from WeChat WeChat official account "national business daily".

Recently, social media such as friends circle were screened by a short film "Wukong".

The film tells the story that the hero, a little boy, loves the Monkey King since he was a child and wants to go to the cinema in the city to see "Make a scene in Heaven". The core of the film focuses on the juvenile spirit of "I don’t know much about heaven".

N+ Finance understands that although this short film did not directly reveal too much information about Huawei itself, it still caused a lot of interpretations, which is undoubtedly the expectation of HarmonyOS system and even Huawei.

Image source: Every photo by reporter Liu Ling

On May 21st, Yu Chengdong, CEO of Huawei’s consumer business, revealed:"As soon as this fall, at the latest next spring, Huawei’s own OS will probably be available.. "

In fact, the domestic mobile operating system has been tried by many manufacturers before. The giants include Baidu (BIDU.US) cloud OS and Tencent (00700)TOS, and the entrepreneurial team once had a little heart OS and Le Frog OS. And the most brilliant achievement belongs to Ali:

At the end of 2015,BABA.US) YunOS surpassed WP to become the third largest mobile operating system in China with a market share of 7.1%., second only to Android and iOS.

Now, times have changed, and Huawei HarmonyOS, burdened with the expectations of Chinese people, can make a scene like Wukong mentioned in the promotional film and fight its way out in the rivers and lakes of the mobile phone operating system?

In the short film Wukong, the little boy, obsessed with the Monkey King, is bent on going to see the Monkey King’s movie in the big city where "there is only one way to go over the back mountain and two more mountains, and it takes one night by car". He goes out alone, encounters a series of "adventures" and finally arrives at his destination in rags.

Some netizens commented that the spirit of the little boy and the spirit of Wukong are in the same strain, and the shadow can also be seen in Huawei.

Huawei officially released the film on May 23rd.

At the same time, Huawei announced that its "spare tire" had turned positive, and its self-developed Hisilicon chip and self-developed operating system "HarmonyOS" attracted much attention. This short film also triggered speculation about HarmonyOS system.

Huawei rarely makes statements to confirm or completely deny the rumors of HarmonyOS system. Ren Zhengfei, founder of Huawei, said in an interview with national business daily on May 21st:

“We can do the operating system, but it is not necessarily a substitute for others.Because we also need it in artificial intelligence and the Internet of Everything, but I don’t know exactly which ones are used and which ones aren’t. "

At the same time, he did not disclose whether HarmonyOS has been used in a small scale within Huawei.

Compared with Huawei’s low profile, "HarmonyOS" system keeps making new progress. On May 24th,The website of China National Intellectual Property Administration Trademark Office shows that Huawei has applied for the "Huawei HarmonyOS" trademark.. The application date is August 24, 2018, the registration announcement date is May 14, 2019, and the exclusive permission period is from May 14, 2019 to May 13, 2029.

Then, on May 29th, it was reported that a few days ago, Huawei submitted a trademark application for "HUAWEI ARK OS" to the European Intellectual Property Office, and "ARK" means "Ark" in English.

At the beginning of June, it was reported from the media that Huawei has started to test the mobile phones that will be equipped with HarmonyOS system, and the number of mobile phones in the test stage has reached one million. At the same time, Huawei also released the interface picture of HarmonyOS system, which is very similar to the current Huawei EMUI. The function arrangement, status bar, font layout and key color matching are almost identical.

On June 3rd, Huawei told N+ Finance that "we haven’t heard of it at all, so we can’t comment" on the rumor of testing HarmonyOS system on 1 million mobile phones.

It is understood that Huawei has been planning its own operating system "HarmonyOS" since 2012, aiming to become a substitute for Google’s Android system.

As for HarmonyOS, it is reported that the operating system has been greatly optimized for Linux (open source) and has been used in Huawei mobile phones (security part).

Combined with such news, Huawei’s HarmonyOS system comes to the fore. Tim Watkins, vice president of Huawei’s Western European market, has previously confirmed to the media that Huawei has been developing an operating system and will launch it soon.

Operating system is the soul of smart phone. As far as the current market is concerned, operating systems are mainly divided into two schools.They are Apple’s iOS system and Google’s Android system, which have a market share of 99%.

Since Apple’s iOS system is only for its own use and not open to other mobile phone manufacturers, Android system has become the only choice for many mobile phone manufacturers in China. Huawei’s EMUI system, Xiaomi’s MIUI system and vivo’s Fun touch OS system are all deeply developed based on Android system.

Wei Yongming, CEO of Feiman Software, wrote an article in 2012, "Why does Huawei Alibaba have to engage in an" independent "operating system? What is the soul of the operating system? ",the article said that taking Android as an example, the operating system open source license constraint is very loose, but:

"Google has certainly accumulated a large number of patents in the process of developing Android, especially Dalvik virtual machine and Java class library, and these patents are above the copyright and license of the software. In other words, if you derive a branch from the existing Android,If you want to sell the software running this derivative version of Android on your mobile phone, Google can immediately take out a patent stick to limit you."

According to Yu Chengdong’s description of HarmonyOS system, all Huawei mobile phones will be equipped with self-developed OS system in the future.Huawei’s self-developed operating system has opened up electronic devices such as mobile phones, computers, cars and tablets, and has been able to support a new software ecosystem for Huawei.

However, at present, the operating system has been occupied by Android and iOS. In order to occupy a place in Huawei’s HarmonyOS system, the first thing to be solved is the problem of software compatibility. After all, no company will adapt software for a system that is not used by many people.

In the research report "From Operating System to Chip-Counting is still stuck in the neck field (I)" released by China Merchants Securities in August 2018, it is pointed out that compared with foreign countries, the technical development of operating system is not a difficulty, nor is it a core factor restricting the development of domestic operating systems.

"The main reason why it can’t occupy a place in the market is that the domestic operating system lacks the ecological environment for high-quality applications."

At present, there are some doubts about the expansion of Huawei’s HarmonyOS system. Before Huawei’s "HarmonyOS", other domestic manufacturers tried to develop their own operating systems, but they didn’t really grow up in the end.

For example, Alibaba Yun OS once occupied 7% of the domestic mobile phone operating system market share from 2014 to 2015, which was also the "peak moment" of the domestic mobile phone system, but then the market share declined rapidly.

Yesterday, Xiang Ligang, the founder of Feixiang.com, expressed another view to N+ Finance. In his view,Huawei has shipped 200 million mobile phones this year, and Apple also has 200 million mobile phones. "Apple’s ecology can be done. Why can’t Huawei be an ecology?"

He said that the outside world’s doubts about Huawei HarmonyOS are mainly at two levels. First, many operating systems, including Windows, have not been done; Second, many people may not develop applications for Huawei systems.

Xiang Ligang said that Windows appeared earlier than Android, and then Android overtook it. The reason why it is not done well is becauseWindows is unfriendly to developers, with poor interface experience and poor interaction ability.

"Windows also charges mobile phone manufacturers, and of course it doesn’t do well. Huawei certainly does not have the problem of charging for its own use.Huawei’s understanding of the operating system has been very profound. And made a new compiler, which is compatible with Android applications.So it’s easy to build HarmonyOS, and I don’t think there is any problem. "

"Many people may not support Huawei’s application.But if Huawei sells hundreds of millions of mobile phones a year, why not apply it?If these applications are very difficult to do, then the current applications are Android, and they can be compatible by running the compiler once. "Xiang Ligang said.

Sun yanbiao, dean of the first mobile phone research institute, believes that the operating system mainly depends on the construction of ecology, and it takes time to build ecology. It took Apple four or five years to build its own ecology, and Android also took four or five years.Under the existing operating system, it will take two to three years for HarmonyOS to do it, and this time is inevitable.

"Why should Internet APP developers develop corresponding apps? This needs to be based on a large user base. What the new ecology often lacks most is the user group. Only by having a large user group can we make a profit, which is essentially a problem of Internet effect. In addition, the ecology that Huawei HarmonyOS needs to build is not only China, but also overseas, so it takes time. "

Sun Yanbiao emphasized that Huawei’s HarmonyOS system could not build a strong ecosystem in a short time, and the construction of this ecosystem was a slow process. "At that time, when Android was going to be an ecosystem, almost all mobile phones except Apple used Android’s operating system, but even in this case, it took almost four years for Android to sprout to rival Apple’s operating system."

Xiang Ligang also told reporters that after the release of the HarmonyOS system, it will change the market structure of global operating systems. HarmonyOS system appears after Android and Windows, and its understanding of operating systems is definitely deeper than that of Android.

"Huawei itself said that if you run it with a compiler, you can improve the efficiency by 60%. Android needs a virtualizer, and it doesn’t start the compiler from the bottom at all, while the HarmonyOS system starts compiling from the bottom, and the efficiency is definitely better than Android. " Xiang Ligang said.

In addition to Huawei, new news has also come from the operating system field.

On May 25th, the media revealed that KaiOS Technologies, the manufacturer of the third largest mobile phone operating system in the world, had received a $50 million financing in Series B..

In addition, ZTE is also developing a mobile phone operating system based on independent intellectual property rights. The industry believes that the operating system may show a diversified trend and is expected to usher in a new round of competition.

The latest news is that on May 31st, it was reported that Mate 20 Pro, which was previously removed by Google, was back, and it continued to support the latest Android Q Beta.

Earlier, Google’s parent company Alphabet announced that it would stop some cooperation with Huawei and erase the name of Huawei Mate 20 Pro on the Android Q Beta page.
