What is the development trend of automobile sensors? Can you talk about it?

With the continuous development of materials science and the rapid development of production technology, special ceramics, optical fibers and semiconductor materials are constantly applied to the sensitive components of sensors, which will further expand the performance and application of sensors. For example, special ceramics have good heat resistance while maintaining their good electromagnetic properties, and are suitable for high temperature environments; Controlling the content of oxides in semiconductor materials is suitable for manufacturing gas sensors.

2. Miniaturization

Semiconductor integrated circuit technology is becoming more and more mature. In this technology, the sensitive element of sensor, signal processing circuit and data processing device can be integrated on one chip. These sensors are small in size, heavy in weight, low in power consumption, convenient for mass production, high in accuracy and low in cost, and more suitable for the application of automobile electronic control.

3. Multifunctional

The detection signal of one sensor can be used by multiple control units, or one sensor can detect multiple data parameters, which can not only greatly reduce the number of automobile sensors, save space, but also improve the reliability of system control. Therefore, the high integration and multi-function of sensors is the inevitable trend of development.

Become smart

With the continuous development of production technology, sensors and large-scale integrated circuits can be effectively combined to form intelligent sensors with CPU as the core, which have the functions of detecting data, automatically diagnosing and processing information. Intelligent sensors that can automatically analyze and judge will quickly improve the intelligent level of automobiles. For example, the advanced driver assistance system, with the help of different types of vehicle sensors, can perceive the surrounding environment during the driving process of the vehicle, carry out dynamic and static identification, provide accurate road data for the on-board computing system, and effectively improve the comfort and safety of the vehicle.

To sum up, with the continuous improvement of people's requirements for automobile safety, comfort and environmental protection, the mobility and intelligence of automobile driving system need to be further improved. As an important part of automobile electronic control system, sensors are widely used in the technical field of automobile electronics, which greatly affects the degree of automobile automation. The rapid popularization of new energy vehicles and the rapid development of intelligent networking technology urgently require sensors to develop rapidly in a more diversified and intelligent direction under the impetus of new materials and technologies. Therefore, R&D enterprises should take the continuous optimization of sensors as a breakthrough to meet the new development momentum of the automobile industry.
