According to the statistics from the China Association of Automobile Manufacturers, in the first half of 2009, the sales volume of cars in China’s auto market exceeded 6 million for the first time, an increase of 17.69% year-on-year. Under the promotion of the entire vehicle market, the Chinese auto parts market has also grown into an attractive cake. However, Chinese companies are not the main beneficiaries of this piece of cake. According to incomplete statistics, foreign investment currently accounts for more than 60% of China's auto parts market, and it has a larger share in the auto parts industry. Experts estimate that it is %the above. At the same time, a large amount of data from the "Car Blue Book - China Automotive Industry Development Report 2009" also shows that foreign capital almost monopolizes all the technical fields of automotive core parts and components, and the situation of the weakest high-end automatic transmission in Chinese enterprises is even more serious. 80% are occupied by imported brands, and the remaining 20% ​​are also almost entirely provided by foreign-controlled joint ventures. The domestic high-end automatic transmission market urgently needs to break through.
Rush to break through the road
In fact, as early as the 1960s, the automatic transmission was listed as a national scientific research project. By 1975, the CA 774 hydraulic automatic transmission with three forward gears was developed, but due to low power transmission ratio, large noise, etc. The demand for passenger cars cannot be met at all, let alone mass production. In 2002, the country set up a special project on the research of automatic transmissions. It allocated funds from the government bond plan to support Shanghai and Tianjin for R&D. After spending two years and more than 800 million yuan in two years, it finally failed. In 2005, after many years of research and development, Geely Automobile launched its Z series 3AT transmission. It has also been a sensation in the industry, but its technology is still difficult to compare with foreign products, and there is a big gap from the market demand. The facts have proved time and time again that it is difficult for the Chinese automatic transmission industry to have substantial development without making up for the shortcomings of core technology.
Ou Yide starts the first shot of technological breakthrough
On June 30, 2009, after years of research and development, China has made a substantial breakthrough in the field of automatic transmissions: China's first high-end automatic transmission with completely independent intellectual property rights - Euro-Electronics full electronic control, low noise, The high-speed, high-applicability, 4-speed automatic transmission was successfully tested in China's largest engine and transmission production base, Inner Mongolia Oy-de-de-engine, which fills another gap in China's core component manufacturing. It is reported that this type of automatic transmission will soon be formally applied to high-end passenger cars, and the company's production of six-speed automatic transmission has also been put on the agenda.
According to industry experts, the technical difficulty that really restricts China's automatic transmission production is the lack of TCU automatic transmission control unit technology. The TCU is like the "brain" of an automatic transmission. Without a "brain", intelligent control of the speed change process is impossible. In order to fundamentally solve the problem of lack of production technology for domestic transmissions, Euro-Idetech Engine Company has introduced its full range of automatic transmission production lines and supporting technologies from the world's top automatic transmission manufacturer, German ZF, and on this basis has specifically addressed TCU control unit technology. Independent innovation was launched, and thus AT control system has completely independent intellectual property rights and reached the world's leading level. It is reported that the control system uses a 32-bit TCM8 controller and has a faster operating speed.
While breaking through the bottleneck of the core technology, Euro-Idetech made bold innovations in the communication protocol between the transmission and the engine. Through collaboration with Bosch, Delphi, Siemens and other companies, Euro-Ide developed an upgraded version of the J1939 agreement. This means that if any of the three companies mentioned above completes the ECU calibration engine, the Euro-Italy transmission can achieve smooth communication with it, which greatly improves the product's matching and application width, and reduces the matching period.
In addition, the European-Italian engine company has also solved the problem of long-term plagued China's entire parts manufacturing quality stability, through the establishment of more than 40 SPC quality control points in the entire plant, in the transmission manufacturing process more than 2000 quality parameters in real time Monitor and automate quality data analysis, and use quality inspection standards for similar European products to ensure that every product on the downline meets the same technical and quality standards as ZF.
It was also learned that Chery, Geely, Jiangling, and other independent brands have also achieved various degrees of progress in the development and introduction of automatic transmission technology while the successful trial production of the Euro-Yide transmission. Not long ago, Geely Automobile completed the overall acquisition of DSI, which is undoubtedly a good thing for China's core spare parts industry that desires technology breakthrough.
