An Intelligent TPMS Solution Based on MEMS Sensor

In this paper, a scheme of intelligent TPMS solution system which based on MEMS sensor is introduced. This paper firstly represents the principle of the resistance MEMS sensor, then discusses the chip design and system implementation. This paper describes the software and hardware in detail. Finally, testing data of the TPMS system are presented. The measured results show that the tire pressure sensing module can precisely measure the tire pressure, temperature and battery voltage. All parameters of the TPMS system can meet the requirements of national standard GB/T 26149-2010.This system can fit the needs of vehicles that requires TPMS system..
