摘 要: 通过对装有双离合器自动变速(dual�clutch transmission,DCT)系统汽车换挡过程的分析,建立了DCT换挡过程的动力学方程。在分析DCT汽车换挡品质影响因素的基础上,设计出两离合器分离、接合速度模糊控制器,并利用挡位传动比的变化对两离合器分离、接合速度模糊系统输出量进行量化修正。仿真结果表明:基于研究所设计的DCT汽车换挡过程两离合器分离、接合速度模糊控制器较好地满足了汽车换挡平顺性和快速性的要求。
关 键 词: 车辆工程;双离合器自动变速器;换挡过程;离合器;模糊控制

Abstract: The shifting process of vehicle equipped with dual�clutch transmission (DCT) has been analyzed and the dynamic equations of DCT have been established. Based on analyzing influence factor of shifting quality for DCT, two clutches separation and engaging speed fuzzy controller has been designed, and output of two clutches separation and engaging speed fuzzy controller was quantized by utilizing change of shift transmission ratio. The simulation results showed in this paper that the two clutches separation and engaging speed fuzzy controller with dual�clutch transmission vehicle can respond to the request that the vehicle shifts smoothly and fast well.
Key words: vehicle engineering; dual�clutch transmission; shifting process; clutch; fuzzy control
