摘　　要：针对混合动力汽车(Hybrid Electric Vehicle,HEV)的能量进行合理管理,能有效提高能量的利用率,减少有害废气的排放。针对单轴并联式混合动力汽车,在对能量平衡分析的基础上,以提高发动机效率和降低油耗为目标,采用电机来平衡发动机上的能量需求,从而控制发动机工作在高效区,并确定了发动机高效区的边界条件。然后,制定了能量平衡控制规则,进行了仿真对比分析。结果表明,与电辅助控制策略相比,能量平衡控制策略中HEV百公里油耗量降低了6.1%,发动机效率提高了8.1%,电机效率提高了10%。The energy management of hybrid electric vehicle（HEV） can effectively improve the utilization of energy, and reduce the emission of harmful gases. In this paper, in order to improve the engine efficiency and reduce fuel consumption, we analyzed the power - balancing of single shaft parallel hybrid electric vehicle, and controlled the engine within its peak - efficiency region by using the motor to balance the energy demand of the engine. On the basis, the boundary conditions of the peak - efficiency region of the engine were determined. And then, we formulated the power- balancing control rules, and carried out the simulation and comparative analysis. The results show that compared with the electric assistant control strategy, the fuel consumption to travel 100 km of HEV with the pow- er - balancing control strategy is reduced by 6. 1% , the engine efficiency is improved by 8. 1% , and the motor effi- ciency is increased by 10%.
