"Shu" encyclopedia | understand direct or indirect tire pressure monitoring, read this article is enough!
With the continuous improvement of the quality of life.
People's pursuit of the quality of life is also getting higher and higher.
The continuous increase of car ownership in China is a good example.
At the same time, the competition in the car market is also increasingly rolling Brand selling price, configuration.
Compared with the previous years to have different degrees of adjustment Especially in the security configuration Tire pressure monitoring belongs to the safety configuration A crucial link Tire are the only part of the car in direct contact with the ground.
Why is tire pressure so important?
Tire pressure is one of the important factors affecting the tire performance and life safety
A sudden flat tire while driving is very dangerous There are many causes of a flat tire Such as tire aging, rolling of sharp objects The highway passes through potholes, overloading, and so on But what a lot of people don't know is that According to statistics, about 90% of flat tire accidents It is caused by insufficient tire pressure So always pay attention to the tire pressure, is the most important!
What is TPMS?
Is in the automotive safety electronic system A very important component of that one It can monitor the tire pressure, temperature and other data in real time Alarm when the tire pressure is too high or too low Thus to help the wheel safety double The TPMS is the third largest automotive safety system with "preactive" models.
According to the working principle and installation mode
The TPMS can be divided into the following two categories:
Direct tire pressure monitoring system (dTPMS)
Indirect Tire pressure Monitoring System (iTPMS)
What's the difference between dTPMS and iTPMS?
direct TPMS（dTPMS）
By the transmitter located in the tire, the controller of the body and the display part located in the central control screen or instrument panel, it can not only monitor the pressure and temperature data of the tire in real time, but also accurately locate the abnormal points according to the abnormal data reflected in the abnormal pressure and temperature of the display part.
indirect TPMS（iTPMS）
The wheel speed signal is collected, and the change of tire pressure is obtained by comparing the wheel speed with the standard pressure state. Report when the wheel pressure is abnormal and display it to the driver on the dashboard, but do not show the specific value of tire pressure and temperature.
It is not hard to see, remove the accuracy, digital, start time, abnormal tire identification, cost, iTPMS (indirect) is also affected by the limitations of the technical principle, increasingly difficult to meet increasingly stringent safety standards of TPMS, make iTPMS (indirect) accuracy is far less than dTPMS (direct), and the iTPMS (indirect) system calibration is complex, simply cannot determine the fault tire, in some cases, for example, the two tires of the same shaft pressure is low, the system cannot even work properly.
Nearly 40 years of ingenuity with you safe travel
Schrader Direct tire pressure monitoring system, own chip research and development, professional more secure, slight leakage timely perception;
● PCB RF antenna, the vehicle speed is within 150km / h, the wireless signal is stable and not lost;
● Battery life is up to 5 years or 70,000 kilometers;
● Intelligent dormancy, reduce energy consumption, prolong the service life;
● In the face of extreme environment can also accurately monitor, Schrader Shide always pay attention to the tire pressure state.
