Design of Pressure-Sensor Based TPMS System Based on SP370

ZHUANG Yan;WANG Ling-yun;ZHANG Guo-yu;WANG Xing-hua;Changchun University of Science and Technology;  
Automobile tire pressure monitoring system(TPMS) is the guarantee of driving safety. This paper studies the structure and working principle of Pressure-Sensor Based TPMS,adopting Infineon SP370 sensor module and TDA5235 RF receiver chip to design a Pressure-Sensor Based TPMS. Focus on solving the tire pressure,tire temperature data real-time monitoring,transmitter is far away from receiver,received signal is not reliable and so on. The designed system is small in size and low in power consumption,In the case of 15 hours driving a day,the module usage cycle is more than five years. And that the temperature and pressure measurement accuracy of data acquisition and transmission module not less than ±2%FS,ensuring the accuracy of data transmission,and when the tire pressure is too high,too low or the tire temperature is too high,the system alarming. Thus,achieving the effectiveness of driving safety,saving fuel consumption.
