Automotive Sensor past simply for the engine, has been extended to the chassis, body and electrical lighting the system. These systems use sensors have more than 100 kinds. In a wide variety of sensors in common: intake air pressure sensor: reflect the intake manifold absolute pressure sensor the size of the car change how much money is the ECU (engine control unit) provides computing injection duration of the reference signal ; air flow meter: measuring the amount of engine intake air is provided to the ECU as the injection time of the reference signal; throttle position sensor: measuring the angle of the throttle open, as provided to the ECU off oil, control the fuel / air ratio, ignition advance angle correction reference signal; crank position sensor: detects the crankshaft and the engine speed, as provided to the ECU determines the ignition timing and sequence of operations of the reference signal; oxygen sensor: detecting the oxygen concentration in the exhaust gas supplied to the ECU as a control the fuel / air than the optimum value (theoretical value) of the reference signal near; and market conditions to launch the car and drive system is still the largest and most mature market of the sensor, but compared with other applications, growth will slow; With the global fuel price increases, "Improved combustion efficiency" will be the new automotive sensor applications "bright spot" in the field; in automotive safety and anti-theft systems will be the fastest growing market; development of emission control systems market is very stable automotive sensors, good prospects. By region several major application market in the United States, mainly for tire pressure monitoring; in the European automotive sensor recognition, pedestrian warning system for automotive; in countries emerging industries, mainly for airbags and automatic seat belt system. In order to measure each vehicle, the largest amount of oxygen sensors, continuous technical progress.
