real-time monitoring tire pressure, abnormal alarm after the driver, to ensure road safety.

Mistakes
· some models of normal tire pressure monitoring system needs to be set, and run from a period of time to acquire. · Even with tire pressure monitoring system can not be completely dependent, or the need for regular manual tire checks confirmed.

Did you know?
· No matter how good your car’s performance, and ultimately from the tire contact with the ground play. Insufficient tire pressure will lead to costs of oil, accelerated tire wear, reduce service life. Tire pressure is too high it will affect tire grip and comfort and so on. So be sure to pay attention to tire condition. · Data show that all the factors that can cause a puncture of the primary reasons for insufficient tire pressure, while the proportion of a car accident caused by a puncture share of the vicious traffic accidents is very high. Journey before it is absolutely necessary to check tires and other components. · Installation of tire pressure monitoring can be accomplished by the late, even some GPS navigation software product or cell phone with this feature can also be used.
– When the air pressure abnormality occurs, an alarm lamp is lit on the instrument prompts the driver.

Technology Principle
The tire pressure detecting system (Tire Pressure Monitoring System, referred to as TPMS) divided into three. One is the direct TPMS (Pressure-Sensor Based TPMS, referred PSB), the other is the indirect tire pressure monitoring (Wheel-Speed Based TPMS, referred WSB). There is also a composite tire pressure monitoring system.
Direct tire pressure monitoring system with a pressure sensor mounted on each tire directly measure the tire pressure, using a wireless transmitter to transmit pressure information from inside the tire to a central receiver module, then each tire pressure data display. When the tire pressure is too low or leakage, the system will alarm.
the indirect tire pressure monitoring device of the direct cost much lower than it actually is to compare the number of rotations of the four tires on the car by the speed sensor ABS braking system, if the the tire wherein a tire pressure is low, only the number of rotation of the tire and the other tire will be different. So long as this feature upgraded ABS system software will be realized. But there are some problems with this indirect tire pressure monitoring. Most of indirect tire pressure monitoring system does not indicate which specific tire abnormality occurs. If the four tires simultaneously insufficient tire pressure will fail. Moreover encounter snow, sand, bend over and other conditions, tire speed difference will be larger, of course, tire pressure monitoring will be useless.
there is a composite tire pressure monitoring system, which is equipped within the tire sensors in two directly mutually diagonally, and with four indirect tire pressure monitoring, the cost can be reduced, to get rid of indirect tire pressure monitoring system can not simultaneously detect a plurality of tire air pressure abnormality occurs drawbacks. However, it still can not provide real-time data within the actual tire pressure as direct tire pressure monitoring system that.
