Domestic sensor

Since the 1980s, the domestic automobile instrument industry has introduced foreign advanced technology and its matching sensor production technology, which has basically met the matching needs of domestic small-batch and low-level vehicles. Because of its late start, it has not yet formed serialization and matching, and has not yet formed an independent industry, and it is still attached to automobile instrument enterprises.

Many cars, light vehicles and some trucks use new electronic products, which require a large number of high-level automobile sensors. However, the highest-level automobile sensor products in China are more than 10 years behind similar products abroad, and more than 500,000 sets of high-performance automobile sensors are imported every year.

In order to enhance the competitiveness of their products, many sensor manufacturers have adopted the way of joint venture with the same foreign industry, digested and absorbed advanced foreign sensor technology, and upgraded their products, thus gradually developing and expanding, and some have become downstream suppliers of several major "EFI" system manufacturers. However, the vast majority of enterprises are only supporting the production of other automotive sensors, which are in a state of low profit, single product and low product quality and technical level.

With the rapid growth of domestic automobile production, the demand of domestic automobile industry for sensors and their supporting transmissions and instruments will also increase greatly in the next few years, so it is imperative to realize the localization of automobile sensors. In order to adapt to this situation, it is an urgent task to focus on developing new sensors such as pressure, temperature, flow and displacement, and to solve the sensors needed by EFI system, air conditioning sewage system and automatic driving system for automobile industry as soon as possible. Automobile sensor is a secondary supporting product for the automobile factory, and it must enter the automobile factory in the form of system. The strength of the first-class system supplier is related to the brand of the OEM, so it is necessary to establish a system platform to drive the development of sensors with the system.
