Research and/or Engineering Questions/Objective: Tire Pressure Monitoring System (TPMS) mainly focus on the tire pressure, temperature monitoring. Or over-inflated tire under inflated, will affect the car’s safety. According to the traffic control department of statistics, 46 % of accidents on the highway due to tire failure caused the puncture accounted for 70 %. TPMS can monitor real-time tire pressure and temperature, the driver informed in advance, improve vehicle safety. And tire pressure is too low will result in increased resistance and improve fuel consumption. Improved by monitoring the tire pressure can improve fuel economy. Methodology: This article describes the principle of TPMS systems, the system components, and solve the TPMS R & D among the key issues to be resolved, providing a human interface and information communications for the overall design performance, and ultimately go through test tools with CAN, the spectrum analyzer, network analyzer test validation. Results: This design of TPMS systems, real-time monitoring of tire pressure, temperature, acceleration, and the man–machine interface can be displayed to the driver. For the tire failures and system failures can itself provide timely text, graphics, alarm. Optimized layout of the entire system through the vehicle to improve the reception rate and reception stability. Communication with other systems using the CAN approach, stable and reliable signal transmission speed. Based on the above system design, in engineering has been widely used to improve the protection of tire safety and fuel economy has made some achievements. Deficiencies and limitations Limitations of this study: This paper focuses on the tire pressure monitoring, and providing alarm. But the puncture cannot be predicted, and the puncture of no implementation action. What does the paper offer that is new in the field in comparison to other works of the author: The system uses sensors directly, in real time and accurate monitoring of tire pressure, temperature, acceleration, battery voltage sensor signal. Relative to the indirect tire pressure monitoring, with a measurement accuracy, system stability, the advantages of wide range of applications. RF signal using FSK modulation mode, better than the adjustment means ASK. Conclusion: This tire pressure monitoring system designed to achieve an accurate tire pressure and tire temperature monitoring alarm display can be applied in the real car.
