On August 9, 2011, the reporter learned that the Auto Electronics Fundamental Software Alliance that was established recently was a “blooming water” in the industry, and the industry’s focus shifted to the development process and industrialization of automotive electronics basic software . On these hot topics, he interviewed Jiang Shui, deputy general manager and technical director of Puhua Software Co., Ltd., one of the initiators of the Automotive Electronics Foundation Software Alliance.

Developing basic software is a trend

"The functions of cars are becoming more and more complicated. The electronic control units need to communicate with each other to interact. Since they need to interact, they need standards." The river pointed out.

Jiang Shui gave reporters a vivid example of the importance of developing independent basic software. He said that Volvo wanted to make improvements to an ECU (Electronic Control Unit) and found a well-known ECU company to design and implement it. The other side offered a price of 530,000 Euros, while Volvo’s internal assessment was 20,000 Euros. Why did it appear so large? Contrast? Because the company that makes ECU thinks Volvo has put forward new function, although the change is not big, but because the software is closed, need to re-design completely, Volvo finally had to spend high price. Jiang Shui told reporters that if software is standardized, it will not cost so much. At present, most of the software platforms of domestic automakers are used abroad. Although they are relatively stable and reliable, they are very expensive. If you want ECUs to expand new features, you will also face the same problems with Volvo. The development of independent automotive electronics basic software standards is "the trend of the times."

Jiang Shui said: "With the increasing proportion of ECUs in vehicles, adoption of open standards will not only reduce costs, but also provide feasibility for future car intelligence." The key to basic software is the operating system. Jiang Shui explained that if there is only a simple communication between car ECUs, it does not require an operating system, but cars will continue to add new functions in the future, and the degree of safety and intelligence will also become higher and higher. This requires that ECUs not only be able to Collect, receive or issue commands, which requires the operating system to solve this problem.

Test and test phase

From the software standard system, AUTOSAR is the most widely used worldwide. Jiang Shui also stated that AUTOSAR is actually a product of the open architecture of IT systems and the integration of automobiles. Therefore, the basic software of domestic autonomous automotive electronics also basically refers to the AUTOSAR standard. Jiang Shui said that in 2010 it released the V1.0 version of automotive electronics basic software, which was mainly based on operating systems. The V4.0 that will be released in 2011 has been extended from a single operating system to the entire platform, which includes four major parts: First, AUTOSAR-compliant operating systems, related development tools, third interfaces, and four additional components such as communication components to solve communication problems. "V1.0 is equivalent to a kernel, and V4.0 is basically a usable platform." Jiang said.

The software version currently under development has already been tested on the vehicle in the vehicle manufacturer, including transmission controllers of FAW hybrid powertrains and heavy-duty truck engine control systems, EPS of the SAIC Roewe series vehicles, and instrumentation of Changan Benben. In addition, PwC made a project for Saab overseas, which can be described as “more flowering”.

Jiang said at the same time that the current software standards developed by the Alliance are only at the demonstration stage of on-vehicle test and testing, and industrialization also needs a relatively large effort to implement. The future work will mainly focus on the following aspects: First, in the vehicle factory and related ECU manufacturers try to promote trials, and secondly, they cooperate with some research institutions or universities to develop experimental platforms. Third, they continue to deepen their technical aspects and carry out targeted localization work.

In addition to technology and evolutionary approaches, exploring new business models is also a very important task for the Alliance. “Because from the current business model of automotive electronics, especially the embedded ones are basically the license fees, but this model can meet the market needs, still have to explore. And this is a constant trial process, It will take some time," Jiang said.

Hardware development must keep up

Although China has realized the importance of developing basic software for automotive electronics, the “Nuclear High Base” project has led to the establishment of a basic software alliance for automotive electronics, providing an opportunity for “acceleration”. However, Jiang Shui also frankly stated that from the perspective of the industry chain, if there is no domestic chip support, it is actually equivalent to “dressing others”.

“Because the software needs to be adapted first, although the automaker provides opportunities to use it in some parts of the lab or even small batches, it is not easy to actually embed it in the ECU. The key is that the ECU is in the hands of foreign manufacturers. "The lack of domestic automobile hardware in the river waterway restricts the current state of the industrialization of software standards." To solve this problem, we must rely on all parties in the industry chain to vigorously accelerate the development of auto electronic chips. Jiang Shui then pointed out that at present, the Union is accelerating the adaptation of ECU products with foreign countries on the one hand, and on the other hand is also uniting all forces to actively promote the state to increase support for the research and development of automotive electronic chips.

In this situation, the attitude of the automaker is particularly important. Jiang Shui mentioned that when the software was developed, there were more or less problems, and our technicians were deciding where FAW, SAIC, and what went wrong on the spot would change. The automaker also gave great support. “This also reflects the importance of knowing the standards of auto manufacturers. One is to grasp the commanding heights in the future, and the other is to hope that through this alliance, the industry chain can be chained together because auto electronics cannot do it alone. It will inevitably require the cooperation of all parties in the industry chain to create a benign and interactive ecosystem.” Jiang said.
