以双离合自动变速器为分析对象,提出并建立了双离合变速器3种状态动力学模型;导出双离合自动变速器换挡过程中各状态下的冲击度表达式;详细分析换挡过程中有无功率循环现象及两离合器不同动作顺序对换挡冲击度的影响;提出了换挡过程中基于发动机转速调节的双离合器控制策略;依托Matlab/Simulink平台建立仿真模型。仿真结果表明,理论分析所得控制策略能有效降低双离合自动变速器换挡冲击。 Taking the dual clutch automatic transmission as the analysis object, three state dynamics models of the dual clutch transmission are proposed and established. The expression of the impact degree of the double clutch automatic transmission in each state is deduced. Cycle phenomenon and the different sequence of the two clutches on the impact degree of the shift. The control strategy of the dual clutch based on the engine speed regulation during shifting process is proposed. The simulation model is set up based on Matlab / Simulink platform. The simulation results show that the theoretical analysis of the control strategy can effectively reduce the shift shock dual clutch automatic transmission.
