摘要
为了满足未来军用混合动力车辆的需求,设计了一种基于起动/发电一体化(integrated starter generator,ISG)技术的军用混合动力总成方案,制定了相应的能量管理策略。基于有限状态机(finite state machine,FSM)理论建立各个工作模式间的逻辑关系及状态转换过程,同时,对各个工作模式下车辆动力源负荷率分配进行了定量分析。以某型军用ISG混合动力车辆参数作为仿真输入条件,利用Cruise/Simulink软件仿真分析整车动力性和经济性,对制定的能量管理策略进行验证。仿真结果表明,军用ISG混合动力车辆与原型车相比动力性获得较大提升,FSM理论能够实现车辆工作模式之间的转换,动力源负荷率的合理分配优化了发动机的运行工况,使得发动机大部分工作点分布在经济工作区内,降低了油耗,所制定的能量管理策略最终达到了提高车辆的动力性、改善车辆的燃油经济性的目的。
To meet the needs of the future military hybrid vehicles, a military hybrid powertrain scheme based on integrated starter generator(ISG)technology was designed, and the corresponding energy management strategy was developed. Based on the finite state machine(FSM) theory, the logic relationship and state transition process between working modes were established, and the load rate distribution of vehicle power source under each working mode was quantitatively analyzed. The parameters of a military ISG hybrid power vehicle were taken as the simulation input conditions, and the power performance and economy of the vehicle were simulated by use of Cruise/Simulink. The energy management strategy was verified. The simulation results show that the power performance of the military ISG hybrid power vehicle is greatly improved compared with the prototype vehicle. The FSM theory can realize the conversion between vehicle working modes. The reasonable distribution of power source load rate can optimize the operating conditions of the engine, which makes most of the working points of the engine distributed in the economic working area and reduces the fuel consumption. Finally, the energy management strategy developes which achieves the purpose of improving the vehicle power performance and fuel economy.
