双离合器自动变速汽车换挡过程离合器模糊控制策略

he shifting process of vehicle equipped with dual-clutch transmission has been analyzed and the dynamic equations of dual-clutch transmission have been established. Based on analyzing influence factor of shifting quality for dual-clutch transmission, two clutches separation and engaging fuzzy controller had been designed, and output of clutches separation and engaging speed of the fuzzy controller were quantized under utilized change with shift transmission ratio. The simulation results showed in this paper that the two clutches separation and engaging fuzzy controller with dual-clutch transmission vehicle can respond to the request that the vehicle shifts smoothly and fast well.
