In order to analyze the configuration of China's automotive electronics in a more systematic and comprehensive manner, and to better analyze the characteristics of China's automotive electronics market for consumers and investors, our company selected nearly 1,000 vehicles from the Chinese market from 2000 to the end of September 2006. The prices of these cars range from less than 100,000 to more than 500,000. We have conducted a survey on the configuration of their automotive electronics, which covers many fields such as automotive safety electronics, in-vehicle communication and navigation electronics, and in-vehicle entertainment electronics. This research report combines the development status of various automotive electronic products in the Chinese market and analyzes based on the results of the survey, with the aim of describing the situation of the Chinese automotive electronic market more clearly.
In foreign countries, the average electronic device on each car accounts for 20-25% of the vehicle cost; some luxury car electronic products even account for more than 50% of the vehicle cost. In 2005, China's automobile production reached 5.71 million vehicles. Affected by the growth of the automobile market, coupled with the continued deepening of the automobile electronic process in 2005, China's automobile electronic product market sales reached 62.43 billion yuan in 2005, compared with 2004. The sales growth rate is as high as 36.3%.
As of the end of October, China's automobile production and sales in 2006 reached 5,891,100 and 576,58, respectively, a year-on-year increase of 27.56% and 25.69%, respectively, surpassing 5.7 million and 5.75 million in 2005. It is expected that the production and sales of automobiles in 2006 will reach and exceed 7 million units. This data is much higher than the market expectation of 6.4 million units in early 2006. Based on this, the Chinese automotive electronics market will also be accompanied by the rapid development of the automobile market.
The development of the automobile industry and the deepening of the process of automobile electronics promote the development of the automobile electronics industry
As a carrier of automotive electronic products, its output directly affects the scale of the automotive electronics market. In 2005, China's automobile industry continued to develop rapidly, and the peak of the Chinese automotive electronics market also followed. In addition to the growth of automobile production, the deepening of the automobile electronic process has increased the rate of automobile electronics. The penetration rate of automobile electronic products in automobiles is getting higher and higher, and the proportion of automobile electronic products in automobile costs is also constantly increasing.
Automotive electronics technology is developing towards "three transformations": networked, intelligent, and integrated development
The application of network and bus technology is more and more extensive. CAN bus will be the most widely used automotive networking solution. More and more sensors will be installed in various parts of the car body to collect dozens of types of information and provide it to the on-board main control computer to intelligently regulate and control the operating conditions; automotive electronic technology will tend to integrate functions and gradually form an economic, effective and Diagnostic data centers, such as the integration of sensor systems to reduce wiring, simplify the control system, and reduce the volume of the sensor system by 60-80%. The products with greater demand in the next few years are: GPS navigation system, automatic transmission control system, ESP system, TCS system, intelligent anti-theft system, car TV, car air conditioner and airbag.
Note: The automotive electronics configuration of this survey is the configuration of pre-installed automotive electronics, which includes standard and optional configurations. The after-installation market is not within the scope of this report.
Pressure sensor usually consists of a pressure sensor and a signal processing unit for measuring the pressure of liquids and gases.
According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors. According to the working principle, it can be divided into Ceramic Pressure Sensor, diffusion silicon pressure sensor, piezoresistive pressure sensor, sapphire pressure sensor and so on.
