摘　　要：为了拓展混联式混合动力汽车动力耦合系统的结构,基于行星排式2挡自动变速器的结构原理设计了一款新型混联式动力耦合系统。以插电式混合动力汽车(PHEV)为例,对其可能存在的多种运行模式进行分析,确定在不同运行模式下,各动力系统和离合器的运行状态。利用AMESim软件与MATLAB软件对该系统进行联合仿真,并将仿真结果与原型车的测试结果进行对比分析,验证了系统的合理性。对于动力耦合机构未来的整车参数匹配和控制变量的选取有重要的指导作用。In order to expand the structure of hybrid vehicle power coupling system,a new type of hybrid power coupling system is designed based on the structural principle of planetary gear two-gear automatic transmission.Taking plug-in hybrid electric vehicle(PHEV)as an example,the possible operation modes are analyzed to determine the operation status of each power system and clutch under different operation modes.AMESim software and MATLAB software are used to carry out joint simulation of the system,and the simulation results are compared with the test results of the prototype car to verify the rationality of the system.It plays an important guiding role in the future vehicle parameter matching of dynamic coupling mechanism and the selection of control variables.
