In view of the state of current market which the automobile tire pressure monitoring system uses the separate designed tire pressure sensor,micro controller and wireless,it has caused the problems such as large volume, cumbersome installation,short service life and high failure rate.This article is based on the SP37 sensor designed and developed by Infineon,which reduces the size of the system measurement module,controlled product manufacturing costs,as well as improves the measurement accuracy,reliability and stability of the system.The TPMS system can display the real-time tire pressure data and warn timely when danger comes in the running process.In the tire pressure testing of automotive field measurement,the system performed stably and achieve the desired purpose.Experimental data show that this design has many advantages such as good stability, high accuracy, and low system power consumption.
