摘　　要：在建立了插电式混合动力农业运输车发动机、电机和电池的数学模型基础上,设计了插电式混合动力农业运输车驱动工况的控制策略,该控制策略采用基于规则的逻辑门限值控制策略,以汽车需求转矩和蓄电池荷电状态SOC为基本控制参数;利用MATLAB/Simulink和Stateflow软件对插电式混合动力农业运输车燃油经济性进行仿真分析。结果显示与相同类型的传统内燃机农业运输车相比,其燃油消耗明显降低,说明所设计的插电式混合动力农业运输车驱动工况的控制策略是有效的,同时分析了整车参数对汽车燃油消耗的影响。After establishing the mathematical model of the engine, the electric motor/generator and the battery for the Plug-in Hybrid Electric Farm Vehicle, this paper design the control strategy of the driving conditions for the Plug-in Hybrid Electric Farm Vehicle. The control strategy use a rule-based logic threshold control strategy and take the requirement torque and the battery state of charge as the basic control parameter. Then the fuel economy for the Plug-in Hybrid Electric Farm Vehicle is simulated with the software of MATLAB/Simulink and Stateflow. The results of the simulation show that: comparing with the same type traditional Hybrid Electric Farm Vehicle, the Plug-in Hybrid Electric Farm Vehicle can improve the fuel economy obviously. So we can conclude that the control strategy of the driving conditions for the Plug-in Hybrid Electric Farm Vehicle is available. In addition, we also analysis the influence of the overall parameter on the fuel economy.
