Inventory | What are the differences between domestic car in-car OS? Hongmeng and AliOS have entered an autonomous no-man’s land

  With the continuous improvement of the level of automotive intelligence, more and more car manufacturers mention the words "system" and "OS" in the promotion of models, such as HarmonyOS of Wenjie M5, IMOS of Zhiji L7, Galaxy OS of Geely Xingyue L, Coffee Smart Cockpit System of Great Wall, and DiLink Intelligent Network System of BYD, etc. This confirms that car manufacturers are paying more and more attention to operating systems.

  According to the classification of the "Vehicle Operating System Standard System" of the National Automobile Standardization Technical Committee, vehicle operating systems are divided into two categories: vehicle operating systems and vehicle control operating systems. Vehicle operating systems are mainly for infotainment and intelligent cockpits, and are used in vehicle control, instrumentation, co-pilot and rear entertainment. The requirements for safety and reliability are at a medium level. This type of operating system is developing rapidly, and the ecosystem relying on this type of operating system is also in a period of rapid development.

  In fact, whether it is all kinds of XXX smart cockpit in China, or the system named "OS", it basically belongs to the category of "car operating system". In the domestic car operating system market, major car manufacturers mainly use QNX, Android, Linux systems and customized modifications based on Android and Linux. The above-mentioned Galaxy OS, coffee smart cockpit system, and DiLink all belong to this program, while the self-developed car operating systems include Zebra Zhixing AliOS and Huawei HarmonyOS.

  AliOS: Distributed Converged, Native Fusion (SOA) Framework

  In April, SAIC Motor officially launched the Zhiji L7. As the first mass-produced model built by Zhiji, the Zhiji L7 brings together the advantages of SAIC Motor Group, Alibaba Group and Zhangjiang Hi-Tech. "The intelligent cockpit and OS system on the Zhiji L7 are all newly developed by Zebra, and a new architecture and system have not been commercially applied yet. Zhiji L7 is the first model of this new system," Liu Tao, co-CEO of Zhiji Automobile, said in an interview with the media.

  Zebra Zhixing built the IMOS underlying system for Zhiji L7 based on AliOS. On Zhiji L7, the smart scene screen and the hub screen are highly integrated, allowing users to interact and stream content between different screens. This is due to AliOS ‘multi-screen interactive display framework, which can break the physical boundaries and achieve a multi-screen graphics system for the cockpit.

  In addition, with the diversification of vehicle functions, more and more information needs to be shared across domains, and a communication framework to meet the cross-domain, cross-device, and cross-OS requirements of smart cars has emerged. AliOS comes with its own autonomous, controllable, stable and reliable Fusion (SOA) framework, which can realize cross-domain and cross-vehicle cloud integrated communication, and supports SOME/IP and DDS protocols. For automakers, Fusion can realize atomization and serviceization of vehicle hardware capabilities, and OEMs can independently define vehicle open capability interfaces and vehicle-cloud integrated developer platforms, which will greatly improve development efficiency.

  HarmonyOS: Full Scene Distribution, Multi-Device Interconnection

  In March this year, Huawei officially released the QJI M5 equipped with HarmonyOS. At the beginning of its birth, HarmonyOS showed that it would integrate various end points in life scenarios to form a "super virtual end point", which is also a significant advantage of HarmonyOS, that is, multi-device interconnection. This is also evident in the QJI M5. In the case of logging in to the same account as Huawei’s mobile phone, the car and mobile phone can be seamlessly connected and transferred.

  In addition, HarmonyOS inherits the capabilities related to the Android application framework, is compatible with Android applications, and also has certain advantages in the richness of the application ecosystem.

  ROM-based system: rich application ecosystem, insufficient stability

  As an intelligent cockpit system deeply customized by Yikatong Technology for Geely Automobile based on the new hardware platform, the Galaxy OS carried by Xingyue L has undergone two OTA upgrades after its launch. Although it is named "OS", Galaxy OS is still a ROM system in essence, and Yikatong has customized development based on Android.

  From a development perspective, the advantages of ROM-based systems are obvious, only involving the modification of SystemUI and a small number of Framework services. The development cycle is short and the difficulty is low, and the advantages of Android’s rich application ecosystem are also favored by major automakers. However, Android is relatively insecure and stable, so most Android-based systems are only used for in-vehicle infotainment.

  Miao Wei, deputy director of the Economic Committee of the National Committee of the Chinese People’s Political Consultative Conference, once said in public: The operating system is the key to the digital transformation of automobile enterprises, and it is a "must for soldiers". Self-developed in-vehicle operating systems have natural advantages in development, iteration, safety and other links, and building autonomous in-vehicle operating systems and even autonomous vehicle control operating systems is the only way.

Deep integration, high-end intelligent manufacturing and service trade empower each other

  Service robots, mobile infrared temperature measurement technology, cool VR panoramic movies can be seen everywhere… Walking through the exhibition halls of this trade fair, new applications brought by innovative technologies such as 5G + 8K, cloud computing, and big data are brilliant, deeply integrated with service trade, and intelligent elements are coming. New technologies empower and point out a new direction for the development of service trade.

  How will 5G new technology change the way we read? Can traditional publications be upgraded into new technology products? In the exhibition area of China Book Import and Export (Group) Co., Ltd., with the help of 3D modeling panoramic dynamic technology, traditional excellent Chinese landscape paintings are presented, allowing the audience to walk into the painting and "play in the mountains and rivers", and experience the scene of "people swimming in the painting" for themselves.

  According to the exhibition area staff, the company is currently actively exploring cross-industry integration development, empowering the publishing industry with new technologies, providing 5G solutions for upstream content production units, and providing 5G smart new services for downstream cultural service units. In the form of naked eye large screen and mobile VR, traditional publications such as picture books and comics are "transformed" into 3D panoramic content, thereby extending the boundaries of publications and updating the reading experience of readers.

  At the China Mobile Migu booth, the audience can not only experience 5G Cloud Gaming Museum, 5G Cloud Gaming, 5G + AI Fitness, 5G + AR Concert, but also experience the "5G New Shooting Method". Using real-time 3D rendering technology, the audience stands in front of the screen and poses, and has their own 3D virtual image. As the audience’s facial expressions and body gestures change, the 3D virtual image on the screen also changes vividly.

  In the exhibition area of Haidian District in Beijing, a "drum" with a diameter of 7 meters and a height of 3.5 meters attracted many people’s attention. According to Liu Lan, deputy director of the Haidian District Cultural Tourism Bureau, this is the digital Yuanmingyuan E-MAX global immersion interactive experience area. Through the 360-degree ring screen and interactive ground screen, once the audience walks into the "Yuanmingyuan Ruins", they can truly show the digital reconstruction image in front of them, and experience the grand scenery of the Yuanmingyuan hundreds of years ago.

  In the special exhibition area of "5G Communication Service", the technical achievements of intelligent networked vehicles displayed by BAIC Group brightened the audience’s eyes and experienced the convenience of smart travel. 5G remote driving technology can help autonomous vehicles achieve remote monitoring and safe takeover in various situations such as loss of GPS signal, limited camera perception, access to blind spots or radar failure. Cai Suoping, member of the Standing Committee of the Party Committee of BAIC Group and deputy general manager of BAIC Group, introduced that the 5G intelligent electric vehicle jointly built by the group with Magna and Huawei is equipped with the intelligent remote control end point of Huawei 5G chip, which can realize functions such as automatic following, lane keeping, automatic lane change, automatic emergency braking, traffic sign recognition and vehicle parking assistance.

  The application of new technologies in high-end intelligent manufacturing and service trade is a pair of twin brothers. You have me, and I have you. The deep integration between them will make life better.

Chen Kexin’s mobile phone shooting "Three Minutes" touched people’s hearts.

  These days, a short film "Three Minutes" has exploded the circle of friends, which tells an unusual reunion in Spring Festival travel rush. The story is very simple. The mother in the film is a train attendant on the "Nanning to Harbin" line. It is the busiest time to work overtime during the Spring Festival, and her son Ding Ding, who is about to go to elementary school, misses his mother, so he asks his aunt to take him to the train station next to his home and meet him while his mother’s train stops on the platform for 3 minutes. This Spring Festival travel rush-themed short film was shot by Hong Kong director Chen Kexin, and the content of the short film was based on a true story. After the short film was launched, it was played more than 13 million times on Youku in one day. Enthusiastic netizens also found the prototype of the story.

  The story is based on true events.

  The joy in the compartment or the joy of meeting relatives on the platform are the most familiar memories of the Spring Festival. This can’t help but remind people of the mainland realistic film "Dear" filmed by Chen Kexin a few years ago. The strong local flavor and sense of reality in the film will also surprise people that the film was produced by a Hong Kong director.

  Outstanding storytelling ability, keen perception of details, concern for reality and strong humanistic feelings are Chen Kexin’s consistent styles. Chen Kexin said that although he has no experience in Spring Festival travel rush, the Spring Festival and reunion are the themes he has been paying attention to for many years. "I can fully imagine the joy and happiness when Spring Festival travel rush comes home." When "Three Minutes" was filmed in Chongqing, Chen Kexin saw the crowds surging on the platform. Although there were all extras in front of him, he was still infected by this feeling of returning home. When the audition actors sang the song of returning home for the New Year, he said that he was also moved to tears.

  The short film touches the audience, not only because the flight attendants are busy on the train every Spring Festival, but also because the most critical structural design of the plot is that after the train stops at the platform, the mother and son meet for only 3 minutes. Three minutes, the sense of time limit brought by this reunion is the tension of the plot. The short film specially emphasizes this sense of time with the creative idea of 3-minute countdown. In the film, the countdown number is displayed at the top of the screen, which reminds the audience that the separation time between mother and son is approaching from the time the train enters the station. When entering the station, my mother saw her son on the platform through the window, but when the door opened, she had to help the passengers get on and off first, so she couldn’t find her son at the first time. Because there were too many people on the platform, my son couldn’t find his mother at the first time. When the child found his mother through the crowd on the platform, the time of 3 minutes has become 2 minutes. When the mother and son met and hugged, the mother waited for her son to speak with eager eyes. An interesting scene happened. After a moment of silence, the son began to recite the multiplication formula loudly. It turned out that my mother had joked with her son who was about to go to elementary school, "If you can’t recite the multiplication table, you can’t go to school, let alone see your mother." On the platform, my son didn’t recite the formula fluently, and at this time, the countdown on the screen was changing rapidly. The mother didn’t know what to do, and she couldn’t bear to interrupt her son. The tense countdown contrasted with the child’s stuttering recitation, which touched the audience’s mood. When my son recited the multiplication formula, the train started. The brief reunion of mother and son left the audience with endless aftertaste without a few words of dialogue.

  During the Spring Festival travel rush season, many people are close to their relatives because of their work, but they can’t stay. The short film "Three Minutes" is based on such a real thing. After the short film was screened, some enthusiastic people found the prototype of the story in the film. She is Liu Zhong, the conductor of the Shenzhen-Urumqi team of Guangzhou Bureau Group Co., Ltd. of China Railway. On January 24, 2017, the media reported the story that Liu Zhong met his son Chen Hongjin (nicknamed Ding Ding) during the four minutes when the train stopped at Hengyang Station after passing through his hometown in Hunan. At the premiere of Three Minutes, director Chen Kexin said that when he first saw the story, he decided to shoot it. In the short film, Tintin recited "99 Multiplication Table" to his mother. In reality, Tintin showed his mother "ma ma wo ai ni" written in pinyin.

  For Chinese people, Spring Festival travel rush is a journey to return home or find their own roots. The director Chen Kexin from Hong Kong has never experienced Spring Festival travel rush, but he has touched countless audiences with simple pictures, regardless of Spring Festival travel rush in the short film.

  Mobile phone shooting movies has its own advantages.

  This 7-minute short film continues Chen Kexin’s narrative style of paying attention to reality and storytelling. What’s more special is that it is a short film shot with a mobile phone all the time, and it is also the first time that Chen Kexin was invited by Apple to shoot a short film with a mobile phone. When sharing his own shooting experience, Chen Kexin said that "Three Minutes" gives the audience some perspectives that traditional films can’t touch. The current mobile phone photography technology has reached a very high level, which can not only record people’s daily life, but also serve as a lens supplement to traditional film photography. In "Three Minutes" shot by mobile phone, the vision of the characters in the picture is more realistic. In the short film, the subjective shot of the little boy crossing the platform to find his mother is completed by putting his hand in front of the little actor, which shows the rhythm and height of the movement, which is closer to a child’s perspective.

  Nowadays, more and more young people without professional training are shooting their own works with their mobile phones. As a daily tool, mobile phones are far beyond the reach of cameras in portability. When shooting in a narrow indoor space, in fact, a considerable space is needed behind the camera to set up the machine, and with such a small device as a mobile phone, you can freely take pictures even in a narrow and crowded train compartment. For the advantages of mobile phone shooting, Chen Kexin greatly praised: "Compared with bulky cameras, mobile phone shooting can try the effect of dynamic camera movement, and it also brings many unique and different shooting angles. For example, you can put your hand frame very close to the actor to capture the true feelings of the characters without making the actors feel disturbed, which is an advantage that traditional large cameras do not have when shooting at close range. "

  After "Three Minutes" was broadcast online, many netizens were surprised that the picture texture taken by the mobile phone could actually achieve the effect of big screen broadcast, but some knowledgeable netizens reminded: "Don’t think that there is only one iPhoneX between you and Chen Kexin’s" Three Minutes ",but it is actually several times more expensive than the mobile phone. Stabilizer, adapter, lens, drone and palm photographer & HELIP; …” In Chen Kexin’s view, all auxiliary equipment is just a tool to help the director establish an emotional link with the audience. The most important thing in filming is not technology, but creativity. Technology is just a tool, and more and more convenient and practical tools provide the possibility for realizing creativity. The short film "Three Minutes" not only impressed the audience, but also clearly conveyed that the future may enter an era in which everyone is a photographer. The development of science and technology is giving more ordinary people and video lovers the opportunity to complete their dreams about images.
