摘  要：针对传统的并联式混合动力汽车（PHEV），通过对其行驶过程的能量平衡进行分析，以提高发动机效率和电机驱动系统的效率为依据，设计了一种ISG并联式混合动力汽车（ISG-PHEV）能量平衡控制策略。在综合路况下进行了仿真，结果表明：与传统无ISG电机的PHEV相比，ISG-PHEV的百公里平均耗油量降低了9.6%。

Abstract: By analyzing power-balancing in the course of driving，a power-balancing strategy for parallel hybrid electric vehicle assisted by an integrated starter generator （ISG-PHEV）was designed for traditional parallel hybrid electric vehicle in order to improve the efficiency of the internal combustion engine(ICE) and the motor drive system. And simulation was carried out in the comprehensive drive cycle, results show that the ISG-PHEV reduces fuel consumption up to 9.6%, compared with an equally powered PHEV without the ISG.
