摘　　要：介绍一种在电动AMT换挡过程出现堵转时通过位置自调整实现换挡的方法。该方法可实现在满足换挡冲击度要求的前提下,采取先恒定占空比,后通过正负斜率的控制方法冲破堵转位置。若该方法失效,则控制执行机构进行位置回退自调整,缩短再次重新进入整个换挡过程的时间,提高换挡单次成功率,提高AMT换挡可靠性。This paper introduces a method of shifting an electric AMT by adjusting the position automatically when there is a stuck rotor during the shifting process.This method can achieve the requirement of gear shifting impact by first maintaining a constant duty cycle and then breaking through the stuck position through a positive and negative slope control method.If this method fails,the control actuator will adjust its position back and shorten the time to re-enter the entire gear shifting process,improve the success rate of a single shift,and enhance the reliability of AMT gear shifting.

关 键 词：堵转 位置自调整 换挡成功率
