According to the Financial Association on August 14, Huawei, which has made frequent actions in “car making” in recent years, said: today, at the 2020 China automobile forum, Wang Jun, President of Huawei’s intelligent vehicle solutions, said, “in the process of meeting the digital transformation of automobiles, Huawei does not build cars. We will focus on the heavy workload and difficulty of development in combination with our own ICT technology accumulation The basic elements of digital platform. < p > < p > on the same day, Wang Jun announced Huawei Hongmeng vehicle system: Hongmeng cockpit operating system HOS, intelligent driving operating system AOS and intelligent vehicle control operating system Vos. Among them, HOS and AOS operating systems have been developed by a large number of partners; Vos can support chip suppliers including NXP. The above three systems are controlled and managed by vehicle stack, a cross domain integrated software framework. Huang Xili, an analyst at Soochow securities, said that under the background of software defined automobile, operating system is the soul of automobile ecological development. Under the great change of intelligent connected automobile industry, the distributed architecture adopted by traditional automobile can not meet the needs of automobile development at this stage because of insufficient computing power, insufficient communication bandwidth and inconvenient software upgrade. The upgrading of E / E architecture has become the key to the development of intelligent connected automobile. < / P > < p > e / E architecture upgrade includes three major upgrades of hardware, software and communication architecture, (from bottom to top) chip + operating system + middleware + application algorithm software + data construction core technology closed loop. Automotive operating system is the soul of software defined automobile ecological cycle development. < / P > < p > in a broad sense, automotive operating systems can be divided into two categories: cockpit domain and automatic driving domain. Cockpit OS pays more attention to application and developer ecology. Due to low functional security and information security, APP application and interface development of central control and instrument is relatively rich. Automatic driving domain OS pays more attention to high real-time and security. Because most of the models have not yet formed automatic driving domain, OS development is still in the early stage. < p > < p > Huawei Hongmeng OS is a customized OS, and there are also similar products VW.OS While BYD dilink, Chery gkui, Weilai NiO OS and Xiaopeng xmartos belong to ROM type OS, which do not involve kernel changes, and generally only modify the application programs of the operating system. < p > < p > Soochow securities is optimistic about the new round of automatic driving market brought by “5g / AI technology progress + Tesla catalysis”. Two core industry chains are recommended: < / P > < p > 1) BSP + middleware + UI supplier: focus on zhongkechuangda, which is the subject of Qualcomm + Huawei industry chain, by deeply binding NVIDIA’s desalvei and Huawei’s Huayang Group, which is the subject of Huawei’s automobile industry chain; < / P > < p > 2) Pay attention to Weilai automobile, ideal automobile, Xiaopeng automobile and Weima automobile with the advantages of core software algorithm, pay attention to the four-dimensional map of high-precision icon, bertley and cobda of chassis electronic standard, and pay attention to the horizon of chip + algorithm mark.
