"There is no modern car sensor technology " has become the industry consensus , which means that the more developed automotive electronics , the higher the degree of automation, the greater the dependence of the sensor . In this regard , industry experts believe that the future will give rise to new automotive applications with supporting new automotive sensors . The most important feature of the sensor is constantly introducing new technologies to develop new features, total future trends in the automotive sensor technology is miniaturized , multifunctional and intelligent.
 
Development trends in the world of automotive sensors
 
Statistics show that a ordinary family car about installing dozens of sensors, the number of sensors on luxury cars can be up to more than 200 . According to market research firm StrategyAnalytics expects 2012 sales of automotive sensors $ 15.8 billion .
 
Vehicle sensors broadly divided into three categories: power systems, safety management systems and body comfort system sensors . Where the market share of the largest power system sensors , automotive sensors embodies the most advanced technology. For example , the angular error of the accelerator pedal position sensor must be within 0.4% ; throttle position sensor requires extremely high reliability , and be able to work in -50 degrees to 150 degrees.
 
In power systems, active sensors to lead the development trend. Cam and crank sensor because the car is closely related to the "heart" of the engine , a key power system . The active cam sensor and crankshaft sensor to provide more protection for the power system, and therefore will lead the future development trend. Expected in 2009 , will have 58.2 million active crank sensor in use, while passive sensors will be reduced to 21.5 million .
 
压力传感器实现侧气囊控制。">Safety management system, the pressure side airbag sensors to achieve control . Automotive safety management system is also widely used in the field of sensors. Auto side airbag control the acceleration and pressure sensors with two programs . Authoritative data show that compared with the acceleration sensor, a pressure sensor detects the speed side impact , nearly three times faster than the acceleration sensor , and an even smaller probability of malfunction .
 
Acceleration, vibration , speed sensor measurement is motorsport three main sensor , has maintained steady and strong growth momentum . Currently, the world production of these three sensors has more than 30 large enterprises , of which the first five companies accounted for 31.3% of the market share. For example Endevco accounted for 13.6%, WilcoxaResearch 9.1% , Motorola accounted for 4.2%, IMI accounted for 3.0%, AnalogDevices accounted for 1.4 %.
