The key to the level of a modern high-class sedan's electronic control system is the use of the sensor's level and quantity. Usually more than 30 species, as many as hundreds of species. It is indispensable for real-time accurate measurement and control Sensor of various information such as temperature, pressure, position, distance, speed, acceleration, attitude, flow, humidity, electromagnetic, photoelectricity, gas, vibration and so on. With the development of China's automobile industry, the development and application of automotive sensors, to achieve the localization of automotive sensors is imperative.

   The growth comes mainly from industrial electronics and automotive electronics, communications electronics, consumer electronics and specialty Temperature Sensor electronic devices, among which the first two are the fastest growing industries in the electronic information industry and the most widely used in sensor applications.

   Sensors for measuring the same amount of pressure, temperature, and acceleration are always the protagonists of automotive electronics. But a large number of systems that require such functions, such as fuel injection control, fuel economy and safety systems (including 'smart' airbags and tire pressure monitoring), have exceeded the need to place a sensor and send the sensor back to the control unit Such a level.

   The emergence of various digital bus systems enables easy centralized processing and simplified wire harness connectivity and makes it possible to take full advantage of the advantages of processing intelligence integrated within the sensor responsible for data acquisition. But this kind of architecture also brings Pressure Sensor the reliability of the worries; In addition, the typical automotive applications continue to reduce costs also face many challenges.

   Similar to the controller area network and more powerful FlexRay bus and other high-speed bus, traditionally used in similar engine and chassis control and other needs of intensive computing, fast processing of the occasion. While low-cost, single-wire-connected local interconnection networks are designed for applications such as seat positioning and temperature control that are not demanding on speed, but focus on simplicity and low cost body electronics applications. Single-line also means lighter weight, which can bring better fuel economy.
As the Chinese product technology grade is still low, in technology and production capacity with the developed countries there is a big gap. This makes some high-grade sensors, MEMS sensors, automotive sensors and special supporting sensors, mainly rely Throttle Position Sensor on imports, only mainland China annual high-performance automotive sensor imports in more than 500,000 sets.
    At present, an ordinary household car will be installed on dozens of nearly 100 sensors, installed in the luxury car on the sensor up to dozens of more than two hundred only. China's industrial process control technology is still very low level, the automotive industry is also rapidly developing, in order to adapt to this situation, focusing on the development of new pressure, temperature, flow, displacement Pressure Switch and other sensors, as soon as possible for the automotive industry to solve the EFI system, air conditioning system and automatic The sensor required for the driving system is a very urgent task.
