Experts predict automotive electronics out of one hundred billion yuan market

In November 5th, one of the highlights of the National Informatization Development Forum 2005 "Chinese automotive electronic technology and Industry Development Forum held in Tianjin. The meeting was organized by the Tianjin Municipal People's government, the Ministry of Information Industry Guide, sponsored by the Information Office of Tianjin Municipal People's government, representatives gathered from industry experts and well-known automotive electronics manufacturers, to discuss the status of China automobile electronic technology and industry development and future trends. Although the experts predict some differences, but it is generally believed that China's current annual output value of nearly 100 billion yuan of automotive electronics, automotive electronics for the automotive industry, flying escort escort.

There is no industrialization without standardization

Even small Min: an important aspect of automotive electronics is an important aspect of the development of standards, such as the promotion of parallel computing platform is good. For example, after the completion of the smart assembly, to build a platform, we must networking, networking what is the problem? The disclosure of the agreement! Is to standardize, not a standard enterprise. Now we have a lot of smart car assembly, engine, transmission, brakes, are intelligent, as well as ABS, EFI system, etc.. But manufacturers do not want to open to the outside world, because it is the technical secrets of enterprises. However, excessive technical confidentiality will inevitably lead to the degradation of the industry. The secret must be restricted, to distinguish between what is required to be kept secret, what is needed to open, such as engine speed, engine fuel consumption and engine information to be made public, as for how you control, you can keep a secret. Therefore, the communication protocol must be standardized, so as to promote the development of the network.

Another is the standard of the central computer. Because the central computer is still a blank car, there is no special international manufacturers, are assembled together. If there is a series of manufacturers can be produced, so it will grab the opportunity.

Tang Xiaoquan: car network model, the use of computer terminology, is to be compatible, compatible is horizontal, the industry chain is vertical, we must consider the industry and home. Here to talk about the famous open network standard in the automotive network SAEJ1939. Bus must first have the demand of automotive network standard commercial vehicle traditional manufacturing mode to seek open parts, because commercial vehicles are from the global procurement of different parts; also are major global commercial vehicle manufacturers, parts suppliers, the main support of semiconductor and information industry. Since the mid 1990s, the population continues to expand, the industry chain has been formed, SAEJ1939 has become the de facto standard of global commercial vehicles, and began to infiltrate other non traffic areas, why the leading German car besides technology, there is a open mind. The automobile network must be deep into Chinese huge traditional parts industry, and the traditional parts together, will evolve into traditional intelligent parts parts with network function, can break through the independent research and development of automobile network industrialization, accelerating the process of industrialization. Why is there no problem with technology, industrialization or not come out? We should also dig deeper problems, may be the reason for the network, not the reasons for the parts, these things together, we can achieve the industrialization process.

Big market needs big"

Zhang Xingye: the car has become the largest carrier of electronic information products, according to the average estimate of Europe and the United States and Japan, the average value of automobile electronic products has accounted for the cost of the car 1/3, which accounted for 4% of the software, and some people think that the software will soon exceed 10%. More and more automotive electronics applications. Then the microprocessor control system, more and more large scale, such as the BMW 7 series engine control by 16bit has been developed to the 32bit microprocessor; the number increasing, the Volkswagen Phaeton has reached 60, and the CAN and LIN bus and network control. The wireless communication and the wireless communication in the vehicle are developing rapidly. And the use of telecommunications, mobile networking can be used, you can use the phone to control the car. In addition, the chip integration is also greatly improved.

Chen Shanghua: electronic technology contribution to the automotive industry indelible. Now the improved vehicle technology simple mechanical rarely, a lot of improvements should be attributed to the application of electronic technology in engine, such as electric EGR (EGR), it can effectively reduce nitrogen oxides (NOx), but it requires a very accurate control, it can only rely on electronic technology to do.

Also, some of the major automotive engine plants now use electronically controlled solenoid valves, if successful, and can cancel the engine's cam
