At present, automotive electronics technology is moving toward automation, intelligence, networking, and information. Therefore, the market for information and communication systems will grow significantly in the next few years. At the same time, the automotive industry in China has been gradually improved over the past 50 years.
With the development of intelligent and information-based automotive electronics, both parties should rely on the concerted efforts of all links in the automotive semiconductor device industry chain to increase cooperation in R&D, production, and marketing.
All sectors of the industry chain need coordinated development. After 50 years of development of the Chinese automobile industry, the automobile supporting industry environment is gradually improving. It has accumulated certain advantages and experience in the production R&D of parts and components such as automotive electronic products and the construction of upstream and downstream industrial chains. . In the manufacturing cost of the entire vehicle company, the cost of its component services is approximately 70%, and the entire vehicle is the terminal of the parts. The competitiveness of the vehicle depends mainly on the parts and components that are provided for it. Both are not allowed. Split, mutually beneficial relationship.
The automotive semiconductor device industry chain includes automotive semiconductor chip and device manufacturers, automotive electronics and other component manufacturers, automotive vehicle manufacturers, including semiconductor chips and device manufacturers are located in the upper reaches of the industrial chain, automotive electronics and other component manufacturers are located in the middle, the car The vehicle manufacturer is located downstream.
In the automotive semiconductor device industry chain, automotive semiconductor chip and device manufacturers are mostly foreign-funded enterprises, mainly Motorola, Infineon, ST, etc.; automotive electronics manufacturers are mostly foreign-funded enterprises and Sino-foreign joint ventures, mainly with the joint automotive electronics Co., Ltd., Beijing Delphi Wanyuan Engine Management System Co., Ltd., Siemens Automotive Electronics Co., Ltd.; automobile manufacturers FAW-Volkswagen, Shanghai Volkswagen, Shenlong, etc.
China's approach to speeding up the process of automotive electronics industrialization is best combined with powerful large-scale electronics companies and powerful auto vehicle companies to form a strategic partnership with complementary advantages and coordinated development. With the development of intelligent and information-based automotive electronics, both parties should rely on the concerted efforts of all links in the automotive semiconductor device industry chain to increase cooperation in R&D, production, and marketing.
Until now, before the introduction of new cars, car manufacturers can already simulate all the functions of the new car. Similarly, semiconductor device manufacturers can extensively use various software to design new components, including semiconductor devices dedicated to automobiles. In the future, before the manufacture of automobiles, it may be possible to simulate the operating conditions of the automobiles. The vehicle manufacturers must cooperate closely with automotive electronics and other component manufacturers, semiconductor chips, and device manufacturers. The three parties should do their best to ensure the Chinese automotive industry. Continuous and rapid development.
Emphasis on overall design of electromechanical integration Currently automotive electronics semiconductor control technology is developing, it will no longer use electronic technology as a mechanical structure to replace or add, but emphasis on the overall design of the automotive electromechanical integration, emphasizing the automotive automation, intelligent , networking and information. Electronic technology has provided more and more functions for automobiles. The increasingly complex requirements for automobiles and transportation facilities include navigation, collision avoidance, automatic charging, night vision and other functions, and even the autopilot system required for future automobiles.
Automotive semiconductor technology, as one of the technical foundations supporting modern automotive engineering, occupies an irreplaceable position in solving problems such as improving vehicle performance, environmental protection, energy, and safety. It is expected that by 2010, the research of automotive semiconductor technology will mainly focus on the auto control of all important components, including the input (sensor and sampling system), output (actuator), control strategy, and implementation method of the electronic control system. From the control theory and practice, it solves the problem that the controlled object is a strongly nonlinear time-varying system and has a random input. Under the premise of low cost, it studies the high real-time, high reliability, and high-precision control system. In the 21st century, automobiles will use electronic computer networks and information technologies, and have made great progress in the automobile's close association with society, including the widespread use of car navigation systems, GPS, and the widespread use of vehicle-mounted information systems, as well as the use of multiple transmission systems (buses. Distributed network) to integrate the electronic control modules of all automotive components, so that the entire automotive electronic system has data fusion, fault diagnosis and certain self-healing capabilities.
At present, the semiconductor technology developed for the automotive field is mainly SiC (silicon carbide), and Panasonic has conducted research on SiC components. Denso predicted the demand in the automotive field 10 years ago and conducted related research. However, the practical application of SiC components in products is still very limited, and Panasonic still fails to reach the practical level. The barrier to popularity of SiC is its higher production costs than silicon. The reason for the high cost lies in the high density of wafer defects and the inability to increase the yield.
Vehicle sensors are one of the key technologies to promote automotive gentrification, electronics, and automation. Countries around the world have paid great attention to the research and development of automotive sensors and the improvement of cost-effectiveness. The more advanced the automotive electronics, the higher the degree of automation, and the greater the dependence on sensors. Therefore, domestic and foreign automotive sensor technologies are listed as high-tech for key development. The development direction of automotive sensor technology is to carry out basic research, discover new phenomena, adopt new principles, develop new materials and adopt new processes, and expand the function and application range of sensors. The smart car is equipped with a variety of sensors that can fully perceive the conditions of the driver and passengers, information on transportation facilities and surrounding environment, determine whether the driver and passengers are in an optimal state, and whether vehicles and people are in danger, and take appropriate measures in time. .
Rapid growth in the application areas of information and communication systems As real-time driving information systems and multimedia devices become more popular in automobiles, China's auto semiconductor market is expected to continue to grow in the next few years. The personalization and versatility of automobiles, wireless and mobile communication technologies will promote the rapid development of the automotive semiconductor market.
In the next few years, the information and communication system will be the fastest growing application area in China's automotive semiconductor device market. The average annual growth rate of the semiconductor device market used by China's auto information and communication systems from 2003 to 2007 will be as high as 51.6%. This is mainly due to the automotive industry. Information and communication systems have great market potential in China. In addition, the automobile body electronic control system and the chassis electronic system are two important fields of application of semiconductor devices. The average annual growth rate of the semiconductor device market scale applied in these two fields from 2003 to 2007 will reach 48.6% and 45.7%, respectively.
