摘　　要：将发动机最优工作曲线和电机最佳效率曲线总称为混合动力汽车广义最优工作曲线,并据此提出了广义最优工作曲线控制策略,其核心是按电池SOC值划分若干区间,在每个区间分别控制发动机或电机工作在最优曲线或最佳效率曲线上。通过与逻辑门限值控制策略进行对比仿真分析,结果表明广义最优工作曲线控制策略可以提高整车燃油经济性,改善发动机和电机的工作效率。The optimal operation line of engine and the highest efficiency line of electric motor together are defined as the broad sense optimal operation line for hybrid electric vehicle （ HEV）, based on which a control strategy for the broad sense optimal operation line is proposed. The core of the strategy is that the states of charge（SOC） of the battery are divided into several sections, in each of which the engine or motor is controlled to operate on the optimal operation line or the highest efficiency line respectively. A simulation analysis is performed with comparison to logic threshold control strategy. The results show that the broad sense optimal operation line control strategy can improve the operation efficiency of the engine and electric motor and enhance the fuel economy of HEV.
