汽车轮胎气压监测系统发展综述

轮胎气压监测系统是汽车上一种新的主动安全技术产品,近年来,在国内外发展迅速。由于它能够实时监测汽车轮胎的气压和温度情况,并能及时给驾驶员以警告,因而可以最大限度地避免由爆胎引发的交通事故,提高了汽车的行车安全。综述了汽车轮胎气压监测系统的发展,包括间接式轮胎气压监测系统、直接式轮胎气压监测系统和下一代无电池轮胎气压监测系统(被动式TPMS)。介绍了各种汽车轮胎气压监测系统的结构组成和工作原理,分析比较了它们各自的优缺点。重点介绍了国外3种主流的直接式TPMS开发系统,对TPMS的研究、开发具有实用参考意义。展望了未来轮胎气压监测技术的发展趋势:无电池TPMS将取代现有类型,成为未来TPMS发展的主流。

Review on Development of Tire Pressure Monitoring System

Tire pressure monitoring system (TPMS) as a new type automobile active safety device has been developing rapidly in recent years worldwide. Since it could monitor tire pressure and temperature in real time and alert the driver in time, most traffic accidents caused by flat tire could be avoided to ensure safe driving. The development of tire pressure monitoring systems is reviewed including wheel-speed based TPMS, pressure-sensor based TPMS and the coming generation so called non-battery passive TPMS. The components and working mechanism of tire pressure monitoring system are introduced and their merits and defects analyzed and compared with the emphasis on three dominant direct TPMS systems, which are significant in its research and development. The prospect of future development trend is looked ahead. The non-battery TPMS is expected to replace the current one and become the dominant.
