The tire pressure monitoring system ( TPMS ) is the third category of automotive safety electronics following foreign antilock brake systems (ABS) and airbags. The standard TPMS usually includes a pressure sensor, an accelerometer, a temperature sensor, an RF module, an MCU, a lithium battery, and the like. After several years of market introduction, TPMS has been recognized within a certain range in China, and some products have begun to be sold in the market. With the expansion of manufacturers' production volume and the intensification of competition, more manufacturers will launch advertising campaigns and upgrade technical service levels in the next phase, which will have a strong interactive effect. In addition, it is the wish of the car owners to improve the safety of individuals and their families by car. The use of a small amount of money for the safety of the car will certainly become a popular choice. In addition, due to the expansion of market volume, manufacturers' production costs will also be greatly reduced, and the result of improved price reduction performance will also promote the popularization and promotion of TPMS, so that the TPMS front-loading market will have more pulling effect. Therefore, the prospect of the TPMS industry is clear. As everyone attaches importance to the safety of automobiles, in the near future, the possibility of mandatory installation of TPMS through legislative forms in the country will increase. The prospects for TPMS are promising. At the same time, TPMS, which is one of the automobile safety protection systems, will develop its transmission module in a highly integrated, simple, and wirelessly passive manner. At present, there are several hundred TPMS developers and manufacturers in China, but the market capacity is small, the penetration rate is low, and the technology needs to be further improved. The front loading market is monopolized by international manufacturers, and domestic manufacturers can only survive in the cracks. If companies do not have the strength to rely on the introduction of foreign TPMS development platforms and production lines to produce products, there is no independent intellectual property rights at all. At present, domestic common programs are mainly provided by companies such as Motorola, Infineon, and General Electric (GE). TPMS Market: Passive High Integration is the Technical Direction At present, the car accident caused by a puncture tire is at the top of the highway accident. The puncture has become one of the road traffic killers. As a tympanic “Busterâ€, TPMS (Tire Pressure Monitoring System) can timely and accurately alarm abnormal pressure tires through real-time automatic monitoring of the vehicle tire pressure during driving, thereby preventing the vehicle from losing control and puncturing. It is reported that the TPMS standard formulated by the National Automotive Standardization Technical Committee at the end of 2012 is expected to be introduced, which will bring tremendous development opportunities to China's TPMS industry. Safety is the most concerned issue in the driving process. The variety of vehicle safety products derived from this is also very diverse. TPMS is one of them. According to statistics, 70% of traffic accidents on China's highways are caused by punctures, and in the United States, this ratio is as high as 80%. How to prevent flat tires has become an important issue for safe driving. The birth of TPMS undoubtedly pointed out the direction for human beings to solve the problem of puncture, and was considered by the industry as one of the most likely high-tech automotive technologies. The TPMS market is also considered to be the most promising market in China's security automotive electronics market. Latency hinders market development At present, the overall market capacity of TPMS in China is relatively small, and the penetration rate is low, and it is still in its infancy. Many people in the industry believe that the introduction of laws and regulations is lagging behind and that policy is not inclined to be one of the reasons. “Government regulation requirements have always been a powerful driving force for the application of new technologies in the automotive industry. TPMS is no exception. However, the country has not yet issued mandatory regulations for the installation of TPMS.†Yang Bin, engineer at Freescale Automotive Electronics Advanced Technology Market, interviewed by the reporter Indicated. Hua Yang Group Planning Department He Hua also told reporters: "In the United States, the popularity of TPMS products is largely due to the tilt of the policy. However, China has not introduced a corresponding policy, so the market will not immediately burst. Actually, some developed countries have legislation in this area very early for the sake of vehicle safety. Liu Yongyong, an engineer of the aftermarket technical department of An Lixin, put forward a proposal to the government: “The relevant experts who formulate TPMS standards should be based on our industry, technology, The TPMS standards tailored to China's national conditions are tailored to their own circumstances such as application development. It is reported that the TPMS standards formulated by the National Automotive Standardization Technical Committee are expected to be introduced by the end of 2012. Most industry insiders stated that if China's TPMS standards are introduced, Undoubtedly, it will bring great incentive to the market. There is no doubt that the TPMS industry has a bright future. He Hua told reporters: "Although China has not yet enacted legislation, the United States' legislation and market coercive measures will affect the development direction of China's entire vehicle. Whether TPMS is installed is a non-trade barrier encountered by export vehicles in some areas. Is there any TPMS? The new selling point of the whole vehicle sales in China is that several domestic cars have adopted the TPMS solution in the design of new cars, and once the new TPMS is installed, it will further realize the pace of industrialization of TPMS. The electronic product market will continue to grow rapidly and the market potential will be further released." Of course, at present, people in the industry are not sure how to grow the market. "The domestic TPMS market is explosive growth or steady growth depends on the nature of the (issued) standard and the consumer's ability to accept increased costs, it is still difficult to predict." Yang Bin told reporters this way. Industry speed needs to expand publicity Regulatory lag is one of them. Low consumer awareness is also one of the obstacles to the development of the industry. "TPMS is like the hidden world of rivers and lakes, Taiping world can not see the hidden figure, only when the fatal danger of the tire, the hidden man can be recognized immediately." Liu Eternal vividly told reporters an analogy. "Accelerating the popularization of TPMS requires the support of national mandatory regulations and policies. On the one hand, it must increase propaganda for owners, and only when the concept is improved, the sense of tire safety can be really established." Liu Yongheng added. Zhang Bo from the TPMS division of Hangsheng Company provided the reporter with a set of data: “40% of consumers believe that it is very important for car tire pressure to remain consistent during high-speed driving, but most of them believe that The tires are mainly caused by the high air pressure and temperature, and have little to do with the low air pressure; 20% of consumers think that using brand-name tires can be replaced regularly and there is no need to monitor tire pressure and temperature.†Visible, many consumers are currently I don't know much about TPMS, I can even say nothing. In the process of publicity and promotion, many people in the industry put forward their own suggestions. Apart from playing the "safety card," and emphasizing that products can improve the safety performance of vehicles, they can also use the "fuel saving card." “Under normal tire pressure conditions, the vehicle is certainly less resistant than the tires in the process of abnormal tire pressure driving, which can achieve the problem of fuel savings. At present, the rapid rise in oil prices, many consumers will be the first choice Oil products are purchased and installed," Zhang Bo explained to reporters. As products are promoted to promote consumer awareness gradually, the market volume will be correspondingly expanded, the manufacturer's production cost will also be reduced, and the result of price reduction will promote the popularization and promotion of TPMS, thus achieving a virtuous circle. Of course, some people in the industry believe that although the number of TPMS suppliers is large, they are uneven and the reliability of products is poor, which is one of the factors that restricts the development of the industry. Passive high integration is the technical direction Regulations and consumer awareness are the external causes of the market, and internal factors are the continuous improvement of TPMS product technology. The working environment of tires is very bad when they are driving at high speeds, which raises higher requirements for TPMS products. In terms of product technology development trends, most industry players believe that passive (ie, no battery) and high integration are the direction of development. "Direct tire pressure monitoring systems require very long battery life, typically 7-10 years. Since the battery is located in the tire, the battery must be lightweight. In addition, low power components must also be selected. Future Trends in TPMS It will probably evolve to a passive system," Yang Bin said. Zhang Bo also believes: "The main technical difficulties of TPMS are concentrated in the emission monitoring module in the tire. At present, due to the use of batteries, TPMS still can not completely solve the following problems: excessive volume, high weight, limited service life, monitoring density No real-time monitoring is possible, stability and reliability cannot be guaranteed. If the tire module is passive, the above problems will be solved." For the TPMS chip, Yang Bin pointed out that the requirements for high-integration (single-chip solution), accurate radio transmission and reception, and recognizable motion or stillness of automobiles indicate the development direction for chip technology. He believes that integrating all the above functions into one package is also one of the development directions of TPMS. He Hua also believes that the TPMS, one of the automobile safety protection systems, will have a highly integrated, single, and wirelessly-powered transmission module. Of course, professional customization is also a trend in the development of TPMS products. Liu Yongheng told reporters that some of Chile's large-scale mine cars have ordered special TPMS products to Anlison, which only has a tire height of 3.6 meters. TPMS, as an emerging automotive electronics product, has a promising market. He Hua told reporters that in 2007 global total TPMS products increased by 96% from 2006 to 92 million units; in 2008, the growth will tend to be stable and is expected to increase by 30% to 120 million sets; by 2011, it will exceed 1.69. Billion sets. According to the TPMS industry research report, there are currently nearly 200 professional and non-professional TPMS manufacturers in China, and it is expected to reach 2,200 in 2010. The Chinese TPMS market will fully explode. We are looking forward to the sound and rapid development of China's TPMS industry.
