摘　　要：文章依据两参数换挡规律,运用模糊控制理论建立了驾驶员模型,采用Stateflow有限状态机理论建立自动换挡模型,并且建立了自动变速器传动模型;对整车动力系统在特定工况下进行仿真分析研究,结果表明该自动变速器模型正确,能严格按照换挡规律换挡。According to the shifting rule of two parameters,the driver model is built by using the fuzzy control theory and the automatic shifting model is built by using the finite state machine（FSM）.The automatic transmission model is also set up.The simulation of vehicle powertrain system under a specific condition show that the automatic transmission model works as expected and can shift by the shifting rule exactly.

关 键 词：自动变速器 换挡规律 模糊控制
