摘　　要：针对ISG型混合动力系统结构、控制复杂,传统开发风险高、周期长、成本高等问题,采用后向仿真的思想,应用Simulink仿真工具,对其动力系统完成了能量管理策略的设计与建模,建立了工况输入模型和驾驶员PI控制模型,结合相关理论公式及试验标定数据对其主要部件如驱动电机、发动机、发电机、动力电池进行了模型建立。结合中国城市典型工况,基于功率分配思想提出了以发动机优先驱动优化发动机工作效率的整车能量管理策略。仿真结果研究表明,仿真模型可以准确模拟实车进行循环工况行驶,完成经济性试验和和实时输出各部件工作特性参数的功能,该模型可以作为动力系统能量管理策略研究和部件参数优化的基础,对车辆前期开发阶段快速确定整车控制策略,提高匹配该系统车型的经济性具有重要意义。Aiming at the problems of ISG powertrain＇s structure complexity and control complexity,some lacks such as high risk,long period and high cost in traditional development and so on,the Simulink simulation tool was applied according to rear simulation thought,the energy management strategy was designed and modeled,the input model and the driver PI controlling model were modeled,the main components such as the driving motor,engine,generator,power battery were modeled combined with relevant theoretical formulas and demarcated test data. Combining with the typical Chinese traffic,the energy management strategy of engine first driving for optimizing engine＇s working efficiency was put forward withing the power distribution. The simulation results turns out that this model can accurately simulate the true bus on the cycle traffic driving and complete the economy simulation and output real-time working characteristic parameters of every parts,it can be the foundation for studying powertrain＇s energy management strategy and optimizing parts＇ parameters,this is useful for confirming the vehicle control strategy in early development period and improving the economy of related matched bus.
