With the improvement of automobile performance and the rapid growth of the Chinese automotive market, more and more sensors are used in automobiles. The Chinese automotive sensor market has entered a period of rapid growth. Data show that from 2007 to 2012, the compound growth rate of China's auto sensor sales will reach 22.37%. The improvement of the performance of the vehicle has also put forward higher requirements on the performance of the sensor. Passive sensors have been difficult to meet the requirements of high precision in some applications, and the application of active sensors will become wider and wider. In addition, for some sensors that have commonality or signal sources that can be shared, high integration will become a trend.
Demand boosts sensor growth
With the continuous improvement of car performance and the ever-increasing requirements of the country for various automotive standards, more and more sensors are required for each car. In addition, China has already leapt to the second largest automobile market in the world. According to data released by the China Association of Automobile Manufacturers, China’s auto production and sales both exceeded 8.8 million in 2007, a year-on-year increase of 22.02%, making it the second largest in the US Car consumer countries are expected to reach 15 million vehicles in 2015.
"The increase in the number of cars and the increase in the number of sensors used in each car will determine that the market size of China's automotive sensors will continue to increase. The Chinese sensor market is entering a booming period." Infineon Automotive, Industrial and Diversified Electronic Markets Shen Shunwei, a senior market engineer in the business unit, is very optimistic about the market prospect of automotive sensors.
iSuppli data show that in 2007 China's automotive sensor market sales reached 120 million US dollars, an increase of 11.85%, from 2007 to 2012, the compound sensor vehicle sales growth rate will reach 22.37%. Zhang Jianchen, Senior Market Manager of NXP Automotive Greater China, also told the China Electronics News reporter: “The Chinese sensor market will continue its high growth rate for the past few years, and sales may exceed 10 billion yuan by 2010. â€
Increased use of active sensors
Green environmental protection and safety are the development direction of the car in the future. In order to make the car more environmentally friendly and safe, the country has also introduced a series of policies and regulations. According to the requirements of the Ministry of Environmental Protection, starting on July 1, 2008, the sales and registration of light vehicles that only met the national II emission standards were completely stopped, and all new vehicles were transitioned to the National III standard. In addition, on March 1, 2008, Beijing took the lead in implementing the National IV emission standards of motor vehicles nationwide. In order to improve the safety of car driving, ABS (anti-lock braking system) has become the standard car, in addition, the end of this year by the National Automobile Standardization Technical Committee developed TPMS (tire pressure monitoring system) standard is expected to come out.
With the continuous improvement of automotive emissions, safety and other requirements, passive sensors can no longer meet high accuracy requirements in certain applications. For example, with the implementation of State III and State IV standards for automobile exhaust emissions, passive sensors for crankshafts and camshafts have not been able to meet the requirements for precise control, which requires the replacement of Hall sensors or giant magnetoresistive sensors. "Active sensors will gradually replace passive sensors." Shen Shunwei told the "China Electronics News" reporter. According to reports, Infineon has introduced Hall sensors and giant magnetoresistive (GMR) sensors with digital processing capabilities this year. Compared with analog output Hall sensors, digital output sensors have higher accuracy and temperature compensation capability, and the output signals are also easier to process. The giant magnetoresistive sensor has the advantages of high sensitivity, fast response, and small and simple structural design, and can achieve a 7mm air gap.
Active sensor applications will become more and more widespread
The improvement of automotive performance and the vigorous development of the automotive market have driven the rapid growth of automotive sensors. Passive sensors have difficulty meeting high accuracy requirements in some applications, and active sensor applications will become more widespread.
