Importance Of Automotive Sensors

As the information source of automotive electronic control systems, automotive sensors are a key component of automotive electronic control systems and one of the core research topics in the field of automotive electronic technology. Automotive sensors measure and control various information such as temperature, pressure, position, rotational speed, acceleration, and vibration in real-time and accurately. The key to measuring the level of modern luxury sedan control systems lies in the number and level of their sensors. Currently, nearly a hundred sensors are installed on an ordinary domestic sedan, while there are as many as 200 sensors on luxury cars.
In recent years, the microelectromechanical systems (MEMS) technology, which has developed from semiconductor integrated circuit technology, has become increasingly mature. This technology can be used to make various micro sensors that can sensitive and detect mechanical, magnetic, thermal, chemical, and biological quantities. These sensors have small volume and energy consumption, can achieve many new functions, facilitate mass and high-precision production, and have low single piece costs, Easy to form large-scale and multifunctional arrays, very suitable for application in automobiles.
The large-scale application of micro sensors will not be limited to engine combustion control and safety airbags. In the next 5-7 years, applications including engine operation management, exhaust and air quality control, ABS, vehicle power control, adaptive navigation, and vehicle driving safety systems will provide a broad market for MEMS technology.
