Car-tire Detection Accuracy

Tire pressure monitoring system has two main solutions, direct system and indirect system.

Direct tire pressure monitoring system is the use of pressure sensors installed in each tire directly measure the tire pressure, and the tire pressure display and monitoring, Car-tire when the tire pressure is too low or leakage, the system will automatically alarm.

1, can not show the exact tire instantaneous pressure value;

2, the same axle or the same side of the wheel or all tire pressure at the same time can not alarm;

3, can not take into account the speed, Car-tire detection accuracy and other factors.

Active system is used in the silicon on the use of mems process to produce capacitive or piezoresistive pressure sensor, the pressure sensor installed in each wheel, Car-tire the way through the radio frequency signal to send out, installed in the cab wireless The receiving device receives the pressure sensitive signal and undergoes a certain signal processing to show the current tire pressure.

The advantage of active technology is that the technology is more mature, the development of the module can be applied to the label of the tire, but the shortcomings of the more prominent, Car-tire the sensor module requires battery power, so there is the problem of system life.

Passive tire pressure monitoring system sensor is designed using a surface acoustic wave, which generates a surface acoustic wave through a radio frequency electric field. Car-tire When the surface acoustic wave passes through the surface of the piezoelectric substrate material, it changes, Car-tire This change in surface acoustic wave can be used to know the tire pressure. Although this technology does not require battery power, but it needs to be integrated into the tire transponder, the tire manufacturers need to establish a common standard is possible to implement.

Tire pressure monitoring system to detect the tire pressure anomalies, only with high resolution to have high accuracy. Battery life is limited and capacity is also affected by temperature. In order to improve the reliability of the system, the sensor is best for passive detection. Car-tire The study shows that the information collected by the tire pressure sensor can be used to monitor and correct the navigation system of the vehicle suspension system. Car-tire Therefore, the future of the car pressure sensor should be set in a variety of functions in a passive intelligent sensor.

Automotive sensors are the fastest growing and most used sensor in recent years. The development of the domestic automobile industry has stimulated the development of automotive pressure sensors. Car-tire Advanced manufacturing technology and process technology have made the performance of sensors higher and higher. Car-tire Tire pressure monitoring is also Increasingly accurate.
