摘　　要：为了实现纯电动客车用自动机械变速器(AMT)快速、平顺、准确换挡,以交流异步电机驱动的纯电动客车为研究平台,分析了无离合器的AMT换挡过程控制方法,研究了电机驱动式AMT执行机构控制方法,开发了纯电动客车适用的无离合器多挡AMT系统.经试验场与北京公交线路上的实际考核表明,所设计的AMT换挡过程控制方法满足实用要求.采用该方式换挡的AMT系统已被小批量应用于纯电动客车和混合动力客车中.In order to realize a quick, smooth, precise shifting process of AMT used on a pure electric bus, the pure electric bus driven by AC motor is taken as the research platform. On the base of analysis of control method for shifting process of AMT without clutch and research of shifting control method of AMT actuators driven by motors, the AMT without clutch was developed for pure electric bus. With the result of conducting field test and on-road test, it is obvious that the shifting performance of the pure electric bus is significantly improved.
