TPMS tire pair system and matching method thereof
Technical field
The present invention relates to a kind of TPMS tire pair system and matching method thereof.
Background technology
System for monitoring pressure in tyre (TPMS, Tire Pressure Monitoring System), carry out Real-Time Monitoring for the principal parameters such as pressure and temperature to vehicle tyre, pressure and temperature that is beneficial to guarantee tire etc. maintains in standard range, play and reduce the probability of blowing out, ruin tire, reduce the effect of oil consumption and vehicle part damage rate.
TPMS comprises a plurality of highly sensitive tyre pressure sensor module be installed on each tire, the data such as the pressure of Real-Time Monitoring tire, temperature under driving or static state, and be transmitted into the included CSRC end of TPMS by wireless mode, demonstrate the pressure and temperature when front tyre through this CSRC end, compare with standard pressure value and the safety temperature set simultaneously, and send corresponding sound, light warning etc. for different abnormal condition.Each tyre pressure sensor module all has an identity heading code (ID), but how the CSRC end is recognized is that the information that sends of which tire and which tire occupy which orientation of automobile and just become the key issue accurately judged, at present, the Chinese invention patent application that application number is 20091003986.9, the signal matching device of disclosed system for monitoring pressure in tyre can address the above problem, and still, it need to manually go operation, do not realize the automation coupling, matching efficiency is low.
In addition, the disclosed vehicle TPMS of the Chinese invention patent application that application number is 201010233995.8 automatic position system, it needs 4 signal source feedways to realize waking up, during assembling, 4 signal source feedways need to be arranged according to the wheelbase of vehicle, be guaranteed that the signal source feedway is corresponding with tire location.When a product line is produced the vehicle of a plurality of wheelbases, need all adjust the position of 4 signal source feedways at every turn, very trouble, reduce work efficiency.
