Sensors for chassis control refer to the sensors distributed in the transmission control system and so on. They have different functions in different systems, but the working principle is the same as the sensors in the engine.
They are mostly used for electronic control of automatic transmission, which is based on the information obtained by the speed sensor or so to process the device of electronic control to control the shiftt and lock the torque converter.
Most of them are sensor of speed, acceleration sensors, angles and so on, which can automatically adjust the height of vehicle based on the detected information and prevent the changes in vehicle posture.
This kind of sensors are based on the sensors of speed sensor, torque sensor or so to make the control system of power steering system can be operated easily and swiftly and to improve the response and so on.
They detect the speed of wheel based on the sensor of angular velocity. When the slip ratio is 20%, the sensor can control the brake oil pressure and improve the braking performance to ensure the maneuverability and stability of the vehicle.
The main purpose of using this type of sensor is to improve the safety, reliability, and comfort of the car. There are a variety of temperature sensors and sunlight sensors used in air-conditioning systems and tire pressure monitor system and so on.
Due to the important role of sensors in electronic control systems, countries around the world attach great importance to their theoretical research, new materials.
Diamond has good resistance against heat and thermal stability. Carbonization only begins to occur on the surface above 1200 °C in vacuum, which only begins to occur above 600 °C in the atmosphere. By this characteristic, a thermal sensor suitable for high temperature is produced, which can be used for temperature monitoring and control from normal temperature to 600 ℃. This kind of sensors are suitable for use in harsh environments with high temperature and corrosive gas, which have stable performance and long service life, which can be used for high temperature measurement in the engine.
In addition, diamond has high deformation rate at high temperatures. By the characteristics, vibration sensors and acceleration sensors used in high temperature can be manufactured. Combined with other materials, it can be used to make pressure sensor which is corrosion-resistant for vibration detection and so on.
Sensors used optical fiber are receiving attention due to high sensitivity, light weight and so on, which are suitable for telemetry. Up to now, many products have come out, such as torque sensors made by optical fiber, and sensors used in the tire pressure monitor system.
In the development and utilization of new materials, due to the development of microelectronic technology and micromachining technology, the sensor is developing towards miniaturization, multifunction and intelligence.
