摘　　要：针对双离合器自动变速器(DCT)电控单元控制策略研究过程缺乏系统性,采用模块化方法将DCT电控单元划分为离合器控制、同步器控制、换挡总成控制以及整车控制四大模块;分析了各个模块的主要功能、划分依据以及各模块之间的控制逻辑关系;分别对各个功能模块的建模过程及控制策略进行了阐述;在此基础上,利用Matlab/Simulink软件平台,搭建了DCT电控单元控制系统的仿真模型;进行了定油门开度下,双离合器自动变速器电控单元控制策略的仿真分析。仿真结果验证了所制定的DCT电控单元控制策略的有效性,为双离合器自动变速器产品开发提供了理论依据。In view of the fact that research of control strategy of electronic control unit for dual clutch transmissions（DCT） currently is lack of systematization,modular approach has been adopted to divide electronic control unit for DCT into four modules,which are clutch control,synchronizer control,shift assembly control and vehicle control respectively.The function for each module has been analyzed and the divided principle and control logic relations among these modules have also been discussed.Moreover,the modeling process and control strategies for each module have been described.On this basis,the simulation model of electronic control unit for DCT has been built using the Matlab/Simulink platform,and the simulation has been carried out at given throttle opening.The results show that the control strategy of electronic control unit for DCT has been validated,which provides theoretical basis for DCT product development.
