Infineon TPMS program force China to prepare for the market to start

With America issued the new mandatory assembly with tire pressure monitoring system (TPMS), the provisions for the application of development into a booster, either overseas or domestic semiconductor suppliers of automotive electronic developers are eager for a fight, to Chinese is booming car market high hopes.

With this in mind, and Infineon Technologies yingheng agent technology and Star Electronics together in August 16th, and 18 days respectively in Shanghai and Shenzhen held a seminar on Infineon TPMS/RKE. Among them, the ShenZhen Railway Station seminar attracted a large number of car manufacturers in Southern China and representatives of automotive electronics developers to participate.

America TPMS application Chinese regulations spawned imagination

At the seminar, the Infineon Technologies Asia Pte Ltd automotive electronics market safety system manager Hu Yun Fat said that in early April this year, the National Highway Traffic Safety Administration issued new regulations, light vehicle factory in the United States (the vehicle gross weight not exceeding 4536 kg, or 10000 pounds) TPMS assembly rate in October 5, 2005 (the first phase), September 1, 2006 (second stage) and September 1, 2007, must reach 20%, 70% and 100% respectively.

Prediction based on Infineon and market research agency Strategy Analytics, the regulations under the drive of the 2005 global 67 million 300 thousand, the new factory has 5 million 800 thousand TPMS light vehicle assembly, the assembly rate of nearly 9%; by 2010, all 79 million 400 thousand new light car factory, there will be 26 million 800 thousand assembly TPMS, the assembly rate rise close to 34%. On the other hand, according to the society of automotive engineering Chinese chairman Zhang Xiaoyu is expected to China auto production will be based on the 2004 5 million 70 thousand sales growth in 2010 10 million. In this case, the industry hopes that once the introduction of relevant laws and regulations, China's TPMS market will give birth to a broad space for development.

In chip suppliers, Infineon Hu Yunfa is expected in the next one or two years, the TPMS market will start China. He called on domestic manufacturers are now beginning to cut TPMS development, once the market starts, you can seize the market growth opportunities.

Actually participated in the seminar, many manufacturers Infineon or is engaged in the development of TPMS. Such as BYD Central Research Institute of automotive electronics engineer Li Yuxiang introduction, the company has embarked on the relevant development, once the time is ripe, you can apply the TPMS system in the company's production of cars.

Infineon TPMS sensor aimed at greater market share

TPMS is mainly divided into two types, one is the wheel speed based on TPMS (WSBS TPMS, indirect TPMS), another type of pressure sensor based on TPMS (PSB TPMS, direct TPMS). Among them, PSB TPMS in function and performance are dominant, which is mainly composed of a TPMS transmitter module installed in the vehicle tire pressure and temperature sensor and a signal processing unit, RF launcher, and installed in the car on the bridge including digital signal processing RF receiver, liquid crystal display unit.

In terms of TPMS sensors, Infineon has launched the SP30, SP12 and SP12T models and other products. SP30 is the first official in the China level postpartum market began to promote sales. In the follow-up products, Hu Yunfa said that Infineon will also launch SP34, SP35, SP36 and SP4x production models, of which SP35 is expected to be in mid 2006 mass production. The main direction is to further reduce power consumption, and through the use of more advanced packaging, further reduce prices.

Hu Yunfa said that Infineon TPMS sensor has unique advantages, including: 1) the "glass silicon glass" three layer stack module, has the best compatibility of the medium, helps to improve the reliability of products; 2) to provide a complete solution: SP30+ wireless transmitter and receiver chip; 3) with low power consumption flow, power consumption is only 0.4 ~ A; 4) a built-in accelerometer; 5) reliability has been verified, has been applied in 10 million cars.

In addition, an automobile company participated in the seminar of the engineer said, through the comparison of different sensors, he believes that the Infineon TPMS sensor is the biggest advantage of a chip with digital interface (SPI), bring the design flexibility for independent TPMS sensor.

Because of these advantages, Hu Yunfa said, in the TPMS sensor market, Infineon will share increased from 50% in 2005 to more than 60% in 2010.
