Research and Development Trend of Vehicle Sensors

Because of the important role of sensor in electronic control system, countries all over the world attach great importance to its theoretical research, new material application and product development.

Diamond has good heat resistance and high thermal stability. The surface of diamond only begins to carbonize above 1200℃ in vacuum and above 600℃ in atmosphere. Using this characteristic, a thermal sensor suitable for high temperature is made to monitor and control the temperature from normal temperature to 600℃, and it is suitable for use in the harsh environment with corrosive gas. It has stable performance and long service life and can be used for middle and high temperature measurement of engines. In addition, the deformation rate of diamond is very high at high temperature, which can be used to make vibration sensors and acceleration sensors used in high temperature environment. Combined with other materials, it can be used as a pressure sensor with high temperature, corrosion resistance and high sensitivity for vibration detection and engine cylinder pressure measurement.

Optical fiber sensor is attracting widespread attention because of its strong anti-interference, high sensitivity, light weight and small size, and it is suitable for telemetry. Many mature products have come out, such as optical fiber torque sensor, temperature, vibration, pressure, flow sensor and so on.

While developing and utilizing new materials, due to the development of microelectronics and micromachining technology, sensors are developing in the direction of miniaturization, multifunction and intelligence. Miniaturized sensor integrates micron-scale sensitive elements, signal conditioners and data processing devices on a chip by using micromachining technology. Because of its small size, low price and easy integration, the test accuracy of the system can be improved. For example, by integrating the micro pressure sensor and the micro temperature sensor and measuring the pressure and temperature at the same time, the temperature influence in pressure measurement can be eliminated through on-chip operation. There are many micro sensors, such as pressure sensor, acceleration sensor and silicon acceleration sensor for collision avoidance. Embedding a miniature pressure sensor in an automobile tire can keep proper inflation and avoid over or under inflation, thus saving fuel by 10%. Multifunctional sensor can simultaneously detect two or more characteristic parameters. The intelligent sensor is intelligent because it has a special computer.

In addition, the response time of the sensor and the interface between the output and the computer are also important research topics. With the development of electronic technology, the technology of vehicle sensors will be improved.Research and Development Trend of Vehicle Sensors
