摘　　要：乘用车轮胎气压过低会对车辆的性能造成严重影响,威胁行车安全.轮胎气压监测系统(TPMS)是监测轮胎气压、及时发出低压报警信号的有效装置.文章介绍了Ⅱ类胎压监测系统的基本原理及特点,并通过实车试验对各种Ⅱ类直接式和间接式胎压监测系统的特性进行了验证.试验表明,直接式Ⅱ类TPMS相较间接式系统欠压报警迅速,而间接式TPMS较直接式更易确认系统故障.Low tire pressure of passenger cars will seriously affect the performance of vehicles and threaten the safety of driving. Tire Pressure Monitoring System(TPMS) is an effective device to monitor tire pressure and send out low pressure alarm signals in time. This paper introduces the basic principles and characteristics of class Ⅱ tire pressure monitoring systems, and verifies the characteristics of various class Ⅱ direct and indirect tire pressure monitoring systems through real vehicle tests. The tests show that the class Ⅱ direct type TPMS has faster under-voltage alarm than the indirect type, while the indirect type is easier to confirm system faults than the direct type.
