More than half of the accidents are in tires，The culprit is tire pressure。Relative tire pressure detection is very important。Data indicates，The proportion of car accidents caused by explosive tires in malignant traffic accidents is very high，Insufficient tire pressure in all factors that will cause explosive tires is the primary cause。This is not sensational，seabet loginEven if you don’t choose a model with tire pressure monitoring，It is also necessary to increase the importance to vehicle tires，Avoid serious damage to people and cars。

When the tire pressure is too high，It will reduce the contact area between the tire and the ground，and the pressure that the tires bear at this time are relatively improved，The grip of the tire will be affected。Another，When the vehicle passes through the ditch or bumpy roads，There is no enough space to absorb vibration in the tire，In addition to affecting the stability of driving and ride comfort，It will also increase the impact of the suspension system，This will also bring harm。At the same time，The hidden dangers of explosive tires at high temperature will also increase accordingly。

Direct tire pressure monitoring device is to use the pressure sensor installed in each tire to directly measure the air pressure of the tire，Use a wireless transmitter to send pressure information from the tire inside to the system on the central receiver module，Then display the gas pressure data of each tire。When the tire pressure is too low or the air leaks，The system will automatically alarm。

The working principle of indirect tire pressure monitoring is: when the air pressure of a tire is reduced，The weight of the vehicle will make the rolling radius of the wheels smaller，As a result, its speed faster seabet iothan other wheels。By comparing the speed difference between tires，To achieve the purpose of monitoring tire pressure。The indirect tire alarm system actually relies on calculating the tire rolling radius to monitor the air pressure。

These two types of tire pressure monitoring devices have their own advantages and disadvantages。Direct tire pressure monitoring device can provide more advanced functions，Measure the actual instantaneous pressure inside each tire at any time，It is easy to determine the fault tire。The cost of indirect system is relatively low，Cars with 4 rounds of ABS (1 rotary sensor in each tire) only need to upgrade the software。but，Indirect tire pressure monitoring device does not have a high accuracy rate of direct system，It cannot determine the fault tire at all，and the system calibration is extremely complicated，In some cases, the system will not work properly，For example, when the two tire pressure of the same car shaft is low。
