Background technology
System for monitoring pressure in tyre (TPMS), English Tire Pressure Monitor System.It effect be, in vehicle traveling process, tire pressure is carried out to real-time automatic monitoring, and tire flat and infrabar are reported to the police, to guarantee traffic safety.
Have data to show, the traffic accident causing by blowing out shared ratio in pernicious traffic accident is very high, and all meetings cause in the factor of blowing out tire pressure not enough in being first cause.This is not to deliberately exaggerate so as to create a sensation, even if you do not select the vehicle with tire pressure monitoring, will improve the attention to vehicle tyre yet, avoids people and Che that serious damage occurs.
When tire pressure is too high, can reduce the area of contact on tire and ground, and the pressure that now tire bears improves relatively, the earth-grasping force of tire can be affected.In addition, when vehicle passes through ditch or jolts road surface, in tire, there is no sufficient space absorbing vibration, except stability and travelling comfort that impact is travelled, also can cause the impact of suspension is put more effort, can bring harm thus yet.The hidden danger of meanwhile, blowing out when high temperature also can increase accordingly.
Tire pressure monitoring mainly comprises direct-type tire pressure monitoring and indirect type tire pressure monitoring, and indirect type tire warning is actually and relies on calculating tire rolling radius to monitor air pressure.The principle of work of existing indirect type tire pressure monitoring is: when the air pressure of certain tire reduces, the weight of vehicle can make this theoretical running radius of tire of taking turns diminish, and causes other wheel of its revolution ratio fast.By the rotating speed difference between comparative tire, to reach the object that monitors tire pressure.
The shortcoming of existing indirect type tire pressure monitoring is: its theoretical running radius of tire obtaining is the average theoretical running radius of tire of motor tire full wheel in rolling process, but from motor tire rolling pressured state, the theoretical running radius of tire in region of contacting to earth is subject to the impact of tire pressure to be greater than the theoretical running radius of tire in the non-region of contacting to earth, therefore, by average theoretical running radius of tire, cannot accurately reflect tire pressure situation.
