An automotive electronics market outlook
As the degree of electronic electronics continues to increase, the market for automotive electronics is also growing and maintaining rapid growth. The market demand for passenger car electronic components in the United States was $2.6 billion in 1988, about doubled in 1993 to $5.4 billion, and reached $14 billion in 2000. The average annual growth rate is 15-16%. Globally, the market size in 2002 was approximately $26.9 billion. By 2007, the market size is expected to reach $35.4 billion. Asia, Central and Eastern Europe will see the fastest growth. In North America and Europe, electronic components account for 10-15% of the total vehicle price. It is estimated that by 2010, the price of automotive electronic equipment will account for 25-30% of the total vehicle price.
To date, the world's largest demand for automotive electronic components is powertrain electronics. Power transmission electronic systems will grow steadily between 2002 and 2007. The body and chassis control electronics will maintain a growth rate of 11.7% and its market size is expected to be 27
US$100 million has increased to US$4.7 billion. Safety and comfort electronic systems will experience rapid growth.
The composition of two automotive electronics and the status quo of China's automotive electronics development
Automotive electronics consists of five main components: (see Figure 1)
1 Power control system: including engine management control system, power steering, AT control and ACC.
2 Safety control system: including airbags, ABS/ASR and SAFE-BY-WIRE.
3 Body control system: including switch control, lighting control, anti-theft system, door lock control, window control, wiper and other body electronics control.
4 Travel control system: including instrumentation, air conditioning and chassis control system.
5 Information systems: including entertainment, mobile communications, GPS navigation and information processing systems.
The status quo of domestic auto electronics companies is late start, small scale, low level, and difficult to support. Due to the late start of domestic auto electronics companies, low technical maturity of products and unstable quality, they are not adopted by vehicle manufacturers. Even if its products meet the technical requirements, they must undergo rigorous test and demonstration by foreign manufacturers. Long-term waiting has caused domestic auto electronics companies to miss a good opportunity. The high entry threshold of the high threshold makes it difficult for them to obtain the opportunity to cooperate with the whole vehicle enterprise. It is difficult to accumulate experience through the application of the product in the automobile to improve the technical level. Only the products can be sold through the after-sales market, and it cannot be an OEM supplier to further Expand the scale of the product. On the other hand, the imperfection of the development system and the lack of core technology can not meet the synchronous development requirements of the vehicle manufacturers and the competitiveness requirements of the products.

Three factors restricting the development of China's automotive electronics products
1 Lack of products with independent intellectual property rights, and foreign auto parts companies apply for patents in China, and carry out “enclosure†to control the Chinese automotive electronics market.
Independent intellectual property rights are a major factor restricting the development of China's automobile industry. For automotive electronics, the development of products with independent property rights is subject to many constraints, as most manufacturers do not have automotive companies. The conditions for simultaneous development can only be in the imitation stage. It is impossible to talk about the real development. Foreign parts companies have already seen this. Every year, major auto companies such as Germany, the United States and Japan apply for a large number of patents in China. In the field of electronics, a large-scale "enclosure" campaign has been implemented. So, even if some domestic enterprises want to develop or have developed their own products, they have to face the patents that have been applied for abroad. A manufacturer who developed a rain sensor for detecting rainfall on a car. At that time, their products had already come out. When they wanted to apply for a patent, they found that a German company had applied for a patent for the product in China, and applied for protection of the working principle. The physical principle is applied for patent protection, this company is difficult to avoid, the product
2 Lack of suppliers that are satisfied with the quality control system of the automotive industry, the main components are subject to foreign countries.
The performance of a product depends on one of the most unstable components that make up this product. It can also be said which grade of supplier will produce what grade of product. As far as automotive electronics is concerned, this problem is more prominent. After the development of a car electronic product, there is no problem in the small batch loading test. However, just a few thousand sets of mass production, many problems have emerged. There are many reasons for this, such as process and other factors, but the instability of the working performance of components is the most common. At present, China lacks professional electronic component manufacturers that provide supporting products for automotive electronic products. There are two main sources of components used. Channels, one is to directly purchase foreign agents such as: various chips and power tubes; another channel is to purchase domestic electronic components manufacturers' products, such as resistors, capacitors and transistors. Automotive products are different from other household appliances and application equipment. Automotive electronic products often involve many dynamic parameters, and many factors affect their performance, such as vibration, temperature, humidity, electromagnetic interference, etc. Establish a supporting supply system that can cooperate with the long-term cooperation, that is, to establish a supporting system for the automotive electronics industry. All the components are required to separate automotive electronic products from other electronic products, and at the same time, the production of automotive electronic products. Manufacturers should use the relevant automotive industry quality system to control their own suppliers.
3 The production management system is not perfect, and it is difficult to produce automotive electronic products with stable performance.
Although China's automobile industry has already achieved a rapid development, behind the rapid development, it has exposed many drawbacks of China's automobile industry. Why are the performance of foreign big-name cars stable? From a technical point of view, they have a powerful and powerful. The R&D team, a stable production process control system and a sound logistics system are what we lack. The production of automotive electronic products is inseparable from the production of complete vehicles. At present, the control of its production process is still in the process of reference and exploration. It is difficult for each manufacturer to form a feasible system, and the auto manufacturers are busy with themselves and have no time to take care of them. Without a viable and rigorous process control system, it is impossible to produce electronic products of stable quality. Without a stable component supplier, it is impossible to produce a car with stable performance.
4 Traditional mechanical parts-based parts companies lack understanding of emerging automotive electronic products and have not invested enough energy in research and development.
The car, first of all, gives the impression that it belongs to a mechanically-structured vehicle. It is difficult to link cars and electronics, computers and wired and wireless network control with traditional concepts, but now with the innovation of automotive technology, electronics and networks Technology is rapidly developing in the automotive field. The automobile is not a single mechanical product. It has developed into an electromechanical combination. In the future, it will not be a single computer control, but a computer network control structured on the CAN bus structure. For auto parts companies with traditional mechanical parts, it really needs a process of understanding, but the automotive electronics market has been developing with rapid momentum. With the price reduction of automobiles, parts companies will feel pressure, especially It is a traditional mechanical parts industry, and some are facing an alternate update period of new products. Under such circumstances, it is not allowed to have too many understandings to consider time. Now, the production of automotive electronic products is a high investment and high profit. Industry needs to invest a lot of energy to really do it, not just the bureau
Four summary
70% of the innovative technologies of automobiles are concentrated on automotive electronics. The development of China's automobile industry is bound to drive the rapid development of the entire industry. The existing mature foreign technology should adopt the attitude of introduction, inheritance, learning and innovation. On the same platform, efforts should be made to catch up, because there is no reason to reject advanced technology and advanced management concepts. Only after fully grasping the new technologies of existing mature automotive electronic products and the related background of the emergence and development of such technologies, We can talk about independent innovation; we strongly advocate independent innovation, but independent innovation needs a strong development cornerstone, analyzes various factors hindering the development of automotive electronics, and overcomes these unfavorable factors in a down-to-earth manner to create an external environment that is truly suitable for the development of automotive electronics. This is the root of the problem. The rapid development of automotive electronics technology is an inevitable trend. We should not always be followers. I believe that through hard work, China's automotive electronics industry will surely lead the way.
