The development trend of sensor application technology in car

Article source:admin Popularity:Published time:2019-11-09 08:52

In today's society, when people choose a car, they pay attention to the function, energy saving, environmental protection and safety of the car, and this demand is constantly improving. Therefore, an electronic control system is widely popular in automotive applications, and the development direction of such electronic facilities is intelligent, multifunctional, miniaturized, and integrated.
Due to the continuous development of electronic control systems, the continuous advancement of sensors has been driven. Its development trend is basically the same as that of electronic equipment, and it is also intelligent, multi-functional, miniaturized and integrated. Therefore, it is necessary to develop a new type of sensor with low cost, high reliability and high precision.

1.1 Develop a new type of sensor

The important basis of the sensor is the material of the sensor. One of the trends in sensor development is the use of complex materials to create sensors with good performance. In recent sensor research, the main changes in materials are: The use of magnetic materials, smart materials, ceramic materials, semiconductor sensitive materials, and synthetic atomic molecular materials; A single type of material is converted into a composite material, and a single crystal material is converted into an amorphous material or a polycrystalline material. In the further development of materials, we should also explore new materials with sensitive effects, and strive to achieve low cost and high performance.

1.2 Intelligent sensor

The intelligentization of the sensor refers to the good integration of the microprocessor into the sensor, enabling the sensor to have information processing and detection functions. The intelligence of the sensor is generally integrated on a substrate by driving a series of peripheral circuits such as driving circuit, processing and detection of signals. The sensor can have some new functions such as self-adaptation, self-diagnosis, logic judgment, and data processing. The sensor that has been processed is not only capable of providing signals to be processed and simulated, but also capable of automatic time drift of information, self-correction of nonlinearity, temperature drift, and amplification of signals. And it has strong anti-electromagnetic interference capability, which can guarantee the signal quality of the sensor and provide very high precision. The smart sensor is characterized by its ease of use, suitable for large-volume production, small size, high performance and many functions.

1.4 Miniaturized sensor
The miniaturization of sensors refers to the integration of micron-level data processing devices, signal conditioners, and sensitive components on a single chip by micromachining technology. Miniaturized sensors are characterized by ease of integration, low cost, and small size, so the accuracy of the test can be greatly improved. What can be produced at present is a miniaturized sensor capable of detecting and sensitive biomass, chemical quantity, thermal quantity, magnetic quantity, and mechanical quantity. Therefore, the miniaturization of sensors has great market prospects.

2 Conclusion
One of the core contents of automotive electronic control system research is sensor application technology, and it is constantly moving towards intelligent, multi-functional, miniaturization and integration. There is a big market prospect for automotive sensors.
