Recently, the Shandong Provincial State-owned Enterprise Independent Innovation Work Conference was held in Weichai . Jiang Daming, deputy secretary of the provincial party committee and governor, attended the meeting and delivered an important speech. During the period, Jiang Daming also attended the launch of Weichai Power's Global R&D Center and the launch of China's first high-voltage common rail electronic control system in batches. Together with Gao Xiaobing, member of the Provincial Party Standing Committee and Minister of Organization, he unveiled the headquarters of Weichai Power 's global R&D center. . The headquarters of Weichai Power's global R&D center mainly includes three units: a technology center, a new product laboratory, and a new product trial center. Among them, Weichai Power Technology Center is a state-level enterprise technology center. In 2009, it was recognized by the Ministry of Science and Technology as a research center for the engineering and technology of commercial vehicle powertrain assembly systems. It has established Taishan Scholars, Batuo Scholars posts, and postdoctoral workstations. The center is responsible for the development of new products such as product design, process development and design, CAE calculation simulation, combustion development, performance development, mechanical development, and electronic control technology, post-processing technology, intake and exhaust technology, new energy power and other cutting-edge technologies. Functions. Weichai Power New Product Test Center is a national accredited laboratories.

It can synchronize engine, power system, and key Parts and vehicle matching research; 72 engine test benches, synchronous test, performance development test and engine certification test; built product development process and product database, providing powerful software for engine development Hardware support. Weichai Power's new product trial production center, with a total investment of 500 million yuan, is equipped with world-class technology and equipment. It is mainly used for testing and verification of various processes and major technological improvements, and can meet the needs of new product testing and small batch trial production. With specialized technology and technical application research capabilities, it can provide powerful technical services for engine R&D and design. Since 2009, overseas high-end talents have joined Weichai one after another. Weichai has provided important positions for them, and has established professional teams, allocated quality resources, and established the New Energy Technology Research Institute, Electronic Control Technology Research Institute, and the Powertrain Research Institute. Vibration and noise research institutes, computational analysis institutes, transmission systems research institutes, engine reliability research institutes and other cutting-edge core technology development platforms have basically formed a modular, matrix-based R&D system, and have created a large number of technological innovation achievements. Among them, the ECU system is one of many scientific and technological innovations independently developed by Weichai. The successful development of ECU, a heavy-duty diesel engine high-voltage common rail electronic control system independently developed by Weichai Group and with independent intellectual property rights, marks a breakthrough in the monopoly of foreign companies in this field. The engine electronic control system is the core technology of the modern diesel engine, in which the ECU is the core of the entire electronic control system and can basically be divided into three modules: hardware, underlying operating software and application layer control software. The most important value of ECU is embodied in the application layer control software, and the hardware and underlying operating software can be customized by a professional company according to the requirements of the enterprise. The mature diesel electronic control systems are all monopolized by foreign companies. The ECU is equivalent to the engine's brain and has its own ECU, representing whether a company has a long-standing core competence. Due to the lack of the core technology of the electronic control system, the development of the diesel engine industry in China has been severely hampered by people for a long time, and the product cost has increased and the profit rate has declined. Therefore, diesel electronic control technology has become a bottleneck restricting the development of China's diesel engine industry. As early as the 1980s, the research work on the electronic control system for diesel engines in China began, especially since the mid-1990s. Many universities, research institutes, and companies have developed electronic control systems. However, the software and hardware development of ECUs require the accumulation of experience and knowledge. Due to the weak foundation, decentralized technical power, lack of sufficient manpower, capital investment, and effective organization and management, China's electronic control technology R&D progresses slowly. This has led to a difficult step in the industrialization of ECUs. Many of the developments are in the sample or pilot stage, and many of the results have even remained in the laboratory. In terms of technology, although there is a certain gap between us and the international advanced level, if we can achieve industrialization, it is still possible to continuously improve and strengthen our own strength in the development process. However, the status quo of the cruel market is like a big mountain, and it is on the road of technological industrialization, which makes it difficult for Chinese enterprises to overcome. Wei Chai, whose mission is to revitalize the national industry, has long realized that it is necessary and important to develop autonomous electronic control systems. Over the years, Weichai has been trying hard to master its own core technologies and strengthen its original innovation capabilities to adapt to the increasingly accelerated upgrading of engine electronic control systems, so that China's internal combustion engine industry can completely get rid of external dependence on core technologies. In 2008, Weichai Group initiated the research and development project of its own ECU, making full use of strategic resources within the group, increasing R&D investment and talent introduction, and establishing a world-class electronic control R&D platform. The electronic control R&D team adopts international advanced development technologies, tools and tools, analyzes and digests and absorbs existing international mature products. It is equipped with a complete development tool chain, defines the organizational structure, and optimizes the traditional ECU development and verification process. Various development-related specifications have been established, and ECU hardware and software development environments have also been established. After several years of hard work, Weichai has now built China's top R&D experimental base. By integrating relevant domestic resources, it has completely overcome the technical difficulties of the engine electronic control system and mastered this core technology in one fell swoop. Weichai's autonomous ECU adopts a 32-bit high-performance microcontroller and has undergone various rigorous tests including three-high test, high-low temperature test at -40-105°C, salt spray test, vibration test up to 10g, EMC test for EMC And more than 1700 hours of accelerated life testing to ensure that the ECU can work in a variety of complex environments. The steady state control accuracy of the autonomous ECU's rail pressure is within 10 bar, and it supports up to 5 injections. It can realize the control, diagnosis and service testing of various subsystems of the entire vehicle and engine to meet the emission requirements of the country V, and the service life is as long as 20,000 hours. The development and production of ECUs not only promoted the independent R&D progress of China's auto and parts industries, but also made significant contributions to the technological progress of the engine industry. It also made Weichai the technological leader in this field. After the ECU is put into production, the cost of the electronically controlled engine can be greatly reduced, and the development of the follow-up new function that meets the market demand will speed up, and the flexibility of the diesel engine fuel system matching application will be greatly enhanced. The industrialization of the autonomous electronic control system has increased Weichai's control and leading ability on the market and technology routes, and has enhanced the competitiveness and discourse power of China's internal combustion engine industry in the international market. With the acceleration of industrialization, the development cost of electronically controlled diesel engines will be further reduced, the development cycle will be gradually shortened, and service and maintenance capabilities will be greatly enhanced. At the same time, the establishment of an autonomous electronic control platform will help create a new order for the engine parts supply market. In his speech, Jiang Daming spoke highly of Weichai’s achievements in independent innovation. He pointed out that in recent years, a number of companies in the province such as the Weichai Group have made remarkable achievements in independent innovation. The development path of these enterprises from small to large and from weak to strong fully demonstrates that independent innovation is the foundation for a company's growth and growth, and it is the foundation of the company's growth and development. With China's first self-developed heavy-duty diesel engine high pressure common rail electronic control system ECU put into the market in batches, Weichai plans to cover its own ECUs from small engines to large engines in the next two years, enabling Weichai's electronic control technology to reach the international advanced level. Build a world-leading all-round electronic control R&D team.
