通过对并联混合动力汽车的离合器进行研究,建立了基于逻辑门控制策略的状态判断模型以及其工作过程模型。分析了离合器在并联混合动力汽车运行中的控制原理,建立了控制模型;通过在Matlab/Simulink平台中对离合器的状态判断及工作状况进行仿真分析,论证了逻辑门控制在并联混合动力汽车离合器控制中的可行性。结果表明,逻辑门限控制策略能有效判断离合器的工作状态,进而执行并实现并联混合动力汽车中离合器的换挡、制动及能量切换等工作。

By studying the clutch of parallel hybrid electric vehicle,the state judgment model and working process model based on logic threshold control strategy are established. The operation control principle of clutch in parallel hybrid electric vehicle is analyzed and the control model is set up. The feasibility of the logic threshold control in the clutch control of parallel hybrid electric vehicle is simulated on the Matlab/Simulink platform about clutch state judgment and working process. The result shows that the logic threshold control strategy can effectively judge the working state of the clutch,and then perform the work of shifting,braking and energy switching of the clutch in the parallel hybrid electric vehicle.
