With the improvement of automobile intelligence, the ECU (electronic control unit) of the whole vehicle increases, and the number of codes is more than 100 million lines. The increase of automobile complexity makes the traditional automobile electronic and electrical architecture overwhelmed. It has become a consensus in the industry to develop a new electronic and electrical architecture. A few days ago, Yang Xiaoming, President of anbofu Asia Pacific region, shared the company's innovation in electronic and electrical architecture. At the same time, he believes that the introduction of the new architecture will change the mode of the intelligent automobile industry chain, and the strategic positioning of the enterprise becomes extremely critical. In 2017, the innovation of electronic and electrical architecture helped to automate assembly and support software in the air upgrade. Anbofu was independent from Delphi business and focused on the automotive cutting-edge innovation fields of software and hardware such as ADAS (advanced driving assistance) and vehicle interconnection. Anbofu has made a high-level generalization of his business - building the "brain" and "nerve" of automatic driving. The brain, in fact, is the intelligent driving system of the car, while the nerve is a new electronic and electrical architecture. At the just concluded US ces in 2020, anbofu also demonstrated the intelligent vehicle architecture (SVA). This set of architecture is flexible and easy to expand, and the assembly process is simple. It can improve the safety of the intelligent network vehicle, and also support the later architecture software update. When talking about the innovation in the design of the new electronic and electrical architecture, Yang Xiaoming said that the SVA of anbofu has three characteristics: first, it emphasizes the separation of software and hardware; second, it separates the input end and output end from the computing center; third, the computing center should play the role of server. The SVA of anbofu firstly changed the original control mode of dozens or even hundreds of decentralized ECUs, and then evolved to the modularization of domain controller. According to Yang Xiaoming, modular design greatly optimizes the complexity of the entire architecture. In the past, it was the harness system that could not realize automatic assembly, but the new architecture made the harness greatly simplified and automatic assembly realized. Secondly, in terms of security, anbofu provides two computing centers for each domain. The domain controller is not only responsible for the computing tasks of the domain, but also can control the adjacent domain. When a key component is unexpected, the redundancy design ensures the stability of the system. Yang said that in their cooperation projects with customers, they have started to adopt domain control design locally. The separation of software and hardware has brought great changes to the iterative upgrading of intelligent vehicles. On the one hand, in the process of function upgrading and expansion, there is no need to conduct long-term vehicle specification Level certification for each module, which greatly shortens the development time; on the other hand, developers can continuously develop the functions required by customers, and directly upgrade through the cloud, that is, the so-called OTA (air upgrade). The industrial chain mode will change the enterprise's strategic positioning into the advantages of new electronic and electrical architecture, such as key modular domain control, simplified harness system, software cloud upgrade, etc., which meet the needs of automobile evolution and is the basic guarantee for the realization of mass production of intelligent vehicles. However, along with the evolution of automobile, it also brings a great challenge of uncertainty. Because the new electronic and electrical architecture will greatly change the traditional business model. The future business model changes, not only in the consumer side, but also in the manufacturing side, who will build the car? "In the process of forming a new industrial chain, we must quickly position ourselves. Which end of the industrial chain do I belong to and where is my boundary?" Yang said In September 2019, anbofu and automobile reached a strategic cooperation. It is planned to jointly establish an automatic driving joint venture company to develop L4 / L5 level automatic driving technology. The role of the host plant and the supplier is changing, and this kind of cooperation is a typical case under the change of industrial chain mode. In the new business model, it needs to explore who should do what, what kind of effect should be achieved, and what mutual benefit should be achieved. In the future, the main engine plant will also be impacted by the software. They will actively engage in software development, and many software development work originally belonging to suppliers will be taken away by the main engine plant. According to Yang Xiaoming, it is not a kind of "interest struggle" for both the main engine factory and the supplier to develop software, but the embodiment of the new model. For ambifort, their software is more focused on vehicle control. The software demands of the host factory are concentrated on the end customers, that is, what kind of applications the owners need, and the software that determines the user experience must be dominated by the vehicle enterprises. He also said the future profits from software would be unthinkable.
