Automotive sensors is to promote the car gentrification, electronic, automation of the key components of one of the countries in the world attached great importance to research and development of automotive sensors. Now, "there is no sensor technology, no modern car," the view has been recognized by the industry worldwide. 

The rapid expansion of the sensor market 

According to the authoritative institutions predict that from 2004 to 2009, the global automotive sensors will show a growth rate of 9% in 2008, market demand is estimated to reach 1.487 billion. China is a hotbed of automotive sensor development, CCW Research (CCWResearch) latest survey data show that in 2006, the Chinese automotive sensors market sales of 3.9 billion U.S. dollars, a growth rate of 42.8%, from 2007 to 2010 China's auto sensor market sales compound annual growth rate of more than 35%. Among them, the market sales in 2007 reached 5.4 billion U.S. dollars, a growth rate of 36.3%; in 2009 sales, its market will be close to 1.05 billion U.S. dollars, up 40.5%; 2010, market sales of over 1.32 billion U.S. dollars, an increase of 35.2%. 

Automobile Research Institute of Tsinghua University Professor Yuan Dahong told reporters: "The technical difficulty of ordinary automotive sensor is not large, at present there are more applications in the car, such as temperature sensors, ABS wheel speed sensors." 

China's rapid development of sensor market, thanks to the rapid development of automobile market. At present, an ordinary family car with about tens to hundreds of sensors installed, and luxury cars on the number of sensors can be up to 200. In 2006, China's auto market exceeded 7.2 million, which exceeded five million passenger cars. Domestic car sales in 2007 will be more than 8 million, car sales will grow with the sensor. 

Environmental protection, safety, smart is the development direction of the sensor 

Currently, the automotive technology upgrades, to bring a higher sensor product quality requirements, mainly in lower cost, greater functionality and higher reliability; more developed automotive electronics, the higher degree of automation of the greater the dependence of the sensor. Therefore, the car home and abroad focus on the development of sensor technology as the high-tech. Automotive sensor applications will not only confined to the engine management system, but more and more environmental protection, security and intelligence together. 

TRW Automotive U.S. in many areas have been successfully developed cutting-edge active safety, passive safety and the environment between the sensor integration technology. 

TRW adaptive cruise control (ACC) system will be long-range radar and short-range radar and vision sensors combine to provide road conditions for drivers and vehicle control status of integrated data. TRW short-range radar system also provides pre-crash information, and support variable channel accessibility. Vision sensor by detecting road signs and the target shape, master road environment changes state. According to TRW engineer, functional extension of the sensor to the next level of vehicle safety.Ground speed radar sensor provides information not only helps to improve the performance of existing security systems such as ABS, active retractor (ACR) and the airbag controller, and also contributes to the implementation of new security features, such as direct-type tire pressure Monitoring (TPM), change lanes to support, activate the brake assist function. "
