Research Of The Hybrid Tire Pressure Monitoring System

Direct tire pressure monitoring system (d-TPMS) is easy to be disturbed, and its battery life is not long while the indirect TPMS can't distinguish the condition that four wheels are low pressure at the same time and there is no way to provide detailed values of the tire pressure for indirect TPMS. This paper proposes a hybrid TPMS to solve these problems. Based on the perfect database of the indirect TPMS, all wheels' detailed pressure can be got by dealing with the data which only comes from a sensor in one wheel. This method combines the advantages of the two sides, which has the advantages of simple structure, low cost, stable and lasting work. Through the real vehicle road test, the effect is good. The development of hybrid TPMS will have a positive effect on the application of TPMS in China.
