The most complete information about Autel TPMS tool
What is TPMS?
As an important part of the automobile, the main consideration of tire performance is tire pressure. Low or high tire pressure will affect the tire performance, reduce its service life, and ultimately affect driving safety.
The full name of TPMS is tire pressure monitoring system. The function of TPMS is to automatically monitor tire pressure in real time during vehicle driving and alarm tire leakage and low pressure to ensure driving safety.
TPMS operating principle
When the air pressure of a tire decreases, the rolling radius of the wheel will become smaller, resulting in its speed being faster than that of other wheels. The tire pressure can be monitored by comparing the speed difference between tires.
The indirect tire warning system TPMS actually monitors the tire pressure by calculating the tire rolling radius; The direct tire pressure monitoring system TPMS directly replaces the valve of the original vehicle with the valve with the sensor, and uses the sensing chip in the sensor to sense the subtle changes of tire pressure and temperature in the static and moving states of the tire, converts the electrical signal into a radio frequency signal, and uses an independent channel transmitter to transmit it to the receiver, so that the vehicle owner can know the tire pressure and temperature of the body tire whether driving or static.
At present, all of them are direct-type tire pressure monitoring systems, and the indirect type has been basically eliminated. Only a small number of vehicles manufactured in 2006 are equipped with indirect type tire pressure monitoring systems.
The tire pressure monitoring system is generally installed on the rim. The built-in sensor senses the pressure in the tire, converts the pressure signal into an electrical signal, and transmits the signal to the receiver through the wireless transmitter. Various data changes or buzzes are displayed on the display. The driver can inflate or deflate the tire in time according to the displayed data, and the leakage can be handled in time, So that big accident can be resolved in small places.
Comparison of direct and indirect TPMS
