摘　　要：混合动力客车通常包含发动机与蓄电池组两种动力源,如何对其输出功率进行分配,使系统总能耗达到最小是控制策略中需要关注的问题.针对客车行驶的特点,结合行驶工况的主客观识别,运用动态规划的方法对车辆动力系统中各部件的需求功率进行分配,并进行了系统仿真.仿真结果表明,与开关控制策略模式相比,该方法能够有效提高混合动力汽车的燃料经济性.There are two kinds of energy sources, usually one engine and a set of batteries, in a hybrid electric bus. The problems of how to distribute the output power between the two sources and how to minimize the total energy consumption need to be concerned in the control strategy. According to the driving characteristics of the bus and the subjective-objective recognition for the driving cycles, the dynamic programming method is used to allocate the required power for each part of the power system. The result of simulation analysis indicates that the proposed method can effectively improve the fuel economy of the bus compared with a switch-mode control strategy.
