tire pressure monitoring system referred to “TPMS”, is an abbreviation for “tire pressure monitoring system” is. This technique, various conditions of the tires is monitored by recording real-time automatic electronic sensor mounted in the tire or tire rotation speed, it is possible to provide effective security for travel. .
Type 1 tire pressure monitoring system system
The tire pressure monitoring system can be divided into two: one is indirect tire pressure monitoring system, a tire is judged by whether or not the rotational speed difference of the tire abnormal; the other is the direct-type tire pressure monitoring system in the vehicle is stationary or during running of the tire pressure and temperature through the installation of four real-time automatic monitoring of tire pressure monitoring sensor inside the tire, and the tire pressure, low pressure, high temperature alarm in time to avoid accidents due to tire failure caused, in order to ensure road safety.
indirect tire pressure monitoring system
indirect tire pressure monitoring system, also known as WSBTPMS, WSBTPMS need to compare the difference between the rotational speed of the tire wheel speed sensors of ABS automobile tire pressure monitoring system to supervisor reachedTire pressure measuring purposes. ABS determines whether locking of the wheels by the wheel speed sensor, to determine whether to start antilock brake systems. When the tire pressure decreases, the weight of the vehicle causes a smaller diameter tires, the vehicle speed will change. WSB speed change will trigger the alarm system to remind the owners pay attention to tire pressure insufficient. Thus the indirect TPMS is a passive type TPMS.
Direct tire pressure monitoring system
direct TPMS yet PSBTPMS, PSBTPMS using a pressure sensor mounted on the tire to measure the tire pressure and temperature, using a wireless transmitter to the tire pressure information from internal to the system on the central receiver module, and tire pressure data display. It occurs when the tire is a high pressure, low pressure, high temperature, the system will alarm owner. And vehicle owners can root, diet car, tire pressure warning location set range value and temperature alarm itself. Thus the direct TPMS is an active type TPMS.
Comparative System
The system may directly provide more advanced features, any time the actual instantaneous measurement of the internal pressure of each tire, the tire is easy to determine the fault. Indirect system cost is relatively low, it has been equipped with four ABS (each tire equipped with a wheel speed sensor) only automobiles software upgrade. However, the indirect system there is no direct system with high accuracy, it does not determine tire failure, but an extremely complex system calibration, the system will not work in certain situations, such as the same axle 2 when tire pressure is lower.
There is also a compound of formula the TPMS, which combines the advantages of both systems, it is equipped with sensors in two directly mutually diagonal tire, equipped with a four and indirect systems. Compared with all the direct system, such composite systems can reduce costs and overcome the indirect system can not simultaneously detect a plurality of tire pressure is too low disadvantages occur. However, it still can not provide real-time data for all four tire actual pressure within the system as well as direct.
2. The tire pressure monitoring system References
In Europe and other countries, the original car tire pressure monitoring system gradually began wife means directly integrated in the tire pressure monitoring system traffic computer, displayed on the instrument console intermediate plate. Tire pressure monitoring system in North America provisions, explicitly require tire pressure monitoring system must occur within two minutes abnormal reaction in the tires, alarm owners. And further provisions in particular: tire pressure monitoring system monitors the tire pressure monitoring sensor does not receive a signal in a tire, or must alarm owner received unevenly.
Many owners may have no concept of tire pressure, how safe is the kind of pressure? Knowledge seen from the tire pressure monitoring system Tire Safety: United States High Speed Committee states: When tire pressure is below 75 percentage standard value, tire pressure monitoring systems must alarm the owners, while the tire manufacturer data for the tire pressure to lower the standard value 30 percentage tire pressure monitoring system needs to alarm the owner. Thus: When the percentage of between 25 to 30 percentage of the standard value on the pressure plate to reduce vehicle tire pressure, it is safe driving.
3. The tire pressure monitoring system systemic action
The tire pressure monitoring system can not only occur in the high-pressure tires, low pressure alarm to remind owners pay attention to traffic monitoring tire pressure at high temperature SonataSecurity, but also can help owners save money fuel-efficient, low-carbon environment to become car owners. TPMS relevant statistical data
tire pressure monitoring system display: run-flat car will consume 3.3 percent of fuel. Many owners may not know tire has a slow leak of natural phenomena, insufficient tire pressure are unaware.
understand the tire pressure monitoring system status through time, to prevent puncture, fuel-efficient and environmentally friendly.
Specific examples of the use of tire pressure monitoring system: high-class car have adopted the technology.
4 embodiment tire pressure monitoring system
a direct TPMS: direct tire pressure monitoring device is to directly measure the tire pressure using a pressure sensor installed in each tire of , using a wireless transmitter to transmit pressure information from inside the tire to a central receiver module, and then each of the tire pressure data is displayed. When the tire pressure is too low or leakage, the system will alarm.
2 indirect tire pressure monitoring: the operation of indirect tire pressure monitoring is reduced when the air pressure of a tire, the rolling radius of the wheel causes the weight of the vehicle becomes small, which results in faster speed than the other wheels. By comparing the difference between the rotational speed of the tire, to achieve the purpose of monitoring tire pressure. Indirect tire alarm system is actually relies on computing the rolling radius of the tire air pressure monitoring. .
3 tire intelligent monitoring system (TPMS) Introduction: It combines the advantages of both systems, it is equipped with sensors in two directly mutually diagonal tire, equipped with a four and indirect systems. Compared with all the direct system, such composite systems can reduce costs and overcome the indirect system can not detect a plurality of tiresAt the same time pressure is too low shortcomings appear. However, it still can not provide real-time data for all four tire actual pressure within the system as well as direct.
