摘　　要：提出了基于对驾驶员行驶需求转矩进行实时分配的混合动力电动汽车整车能量管理策略.针对一款双电机结构的并联式混合动力电动轿车的特点,提出以发动机稳态状态下的燃油消耗率特性图为基础,将车辆行驶需求转矩合理地分配给发动机、主电机及ISG,从而实现降低发动机燃油消耗,维持电池SOC平衡的控制目的.按此能量管理策略建立该电动轿车的控制器模型,并将其整体嵌入电动汽车前向仿真软件HEV S im中的相应整车模型中进行仿真测试,仿真结果达到控制要求,证实该能量管理策略具有合理性与可行性.An energy management strategy for the hybrid power electric vehicle based on timely distributing the demand torque for driver is presented. In the light of the characteristic of a parallel hybrid power electric car with two electric motors, a strategy which distributes the vehicle＇s demand torque of driving reasonably to the engine,the main electric motor and ISG based on the specific engine fuel consumption map of steady-state is introduced, consequently the control goal of decreasing the fuel consumption of engine and keeping the balance of battery SOC can be realized. According to this energy management strategy, the controller model of this hybrid power electric car is built and embedded integrally into the corresponding vehicle model of the electric vehicle facing-forward simulation software-HEVSim. The result of the simulation achieves the control requirement and confirms the rationality and feasibility of this energy management strategy.
