摘　　要：加速工况是车辆运行的非稳定工况,传统车辆在该工况下是为了保证足够的动力性而消耗大量燃油。通过对混合动力汽车加速工况的试验测试,研究混合动力系统能量流控制策略,分析混合动力汽车在加速工况下如何保障足够动力性而又能有效控制燃油消耗,达到既有足够动力又有效控制燃油消耗的目的。结果表明:混合动力汽车加速工况下发动机仍然能保持一个相对稳定的工作状态,而又不失动力性,很好地节约燃油,减少排放。Acceleration cycle is not a steady cycle that the vehicle runs. When the conventional vehicle is accelerating, it will consume more fuels to ensure enough power. A test is made on the acceleration cycle for hybrid power vehicle and the control strategy of energy flow is provided to analyze how hybrid power vehicle assure the sufficient power and control effectively the fuel consumption at the acceleration cycle to realize the enough power as well as the fuel economy. The result indicates that the engine can still be in a steady running state at the acceleration cycle without the lack of power, and with more fuels saved and less emission.
