摘　　要：应用PSAT前向仿真软件,建立了双离合器式并联PHEV仿真模型。在确定了PHEV整车性能约束条件并对动力总成主要部件进行了成本分析之后,对不同全电力续驶里程和动力电池类型的PHEV动力总成进行了优化。结果表明:动力电池设计容量对整车成本影响最大,而它主要取决于所要求的全电力续驶里程;随着所要求的全电力续驶里程的增大,所需电机最大输出功率升高,而发动机最大输出功率则降低。The simulation model for a parallel plug-in hybrid electric vehicle （PHEV） with dual clutch is developed by using forward simulation software PSAT. After the performance constraints of PHEV are defined and the key component costs of its powertrain are analyzed, an optimization on the powertrain of PHEV with different all electric ranges （AER） and different types of power battery is conducted. The results show that the designed capacity of power battery, which mainly dependeds on the AER required, has most effect on the cost of complete vehicle, and as the required AER increases, the desired maximum output power of electric motor rises and the power peak of engine reduces.
