| 摘 要： | 通过分析机电控制无级变速器(electrical-mechanical continuously variable transmission，EM-CVT)的结构特点，提出了搭载EM-CVT混合动力汽车的传动方案，建立了动力源数值模型、EM-CVT模型，分析了混合动力系统工作模式，并针对模式切换时的冲击问题，以减小冲击度为目标，通过分析典型工况下动力源输出转矩特性和各部件的动态特性，提出了基于发动机、ISG电机、自动离合器以及EM-CVT相互协调控制策略。利用MATLAB/SIMULINK仿真平台建立混合动力传动系统动力学模型，并对典型的模式切换过程进行了仿真分析。结果表明，所提出的控制策略能够有效控制混合动力传动系统在模式切换时产生的冲击,提高了混合动力汽车的驾驶舒适性。

| Abstract: | Configuration of hybrid electric vehicle equipped with electrical-mechanical continuously variable transmission(EM-CVT) is put forward based on the analysis of work principle of mechanic-electric CVT. The mathematic models of power sources and EM-CVT are built up. According to configuration, the HEV working modes are defined. Based on the dynamic characteristics of drive line, a control strategy for mode-switch is put forward to reduce switch shock. Engine, ISG-motor, automatic clutch and EM-CVT are controlled integrally in this strategy. Forward simulation model of HEV is built on MATLAB/SIMULINK platform. Simulation results show that the switch shock is controlled in an acceptable range by using the proposed control strategy. |
