【摘要】 针对某款CVT并联混合动力汽车,基于各部件的实际响应特性在AMESim软件上建立整车模型,基于规则控制思想,结合驾驶条件估计驾驶员需求转矩,根据该混合动力汽车的工作模式以及工作模式的切换条件,开发了一种基于发动机最优的能量管理策略。通过MATLAB/Simulink和AMESim联合仿真平台,对所开发的发动机最优的能量管理策略进行仿真验证,仿真结果表明,在实现电量平衡的条件下,发动机工作点基本处于低油耗区域,NEDC工况下百公里油耗为6.9L,达到了预期的控制效果。文中提出的混合动力汽车能量管理方法,对混合动力汽车能量优化算法的开发和工作模式协调控制的研究具有一定的指导意义。更多还原

【Abstract】 For a certain continuously variable transmission(CVT) parallel hybrid electric vehicle,the vehicle model was integrated on the AMESim software based on the real characteristics of each component.Based on the idea of rule control,the driver’s demand torque was estimated combined with driving conditions.According to the working modes of the hybrid electric vehicle and the switching conditions of the working modes,an energy management strategy based on the optimal engine was developed.Through the co-simulation platform of MATLAB/Simulink and AMESim,the simulation verification of the energy management strategy based on the optimal engine was developed.The simulation results show that the energy management strategy can basically achieve the electric power balance,and the engine operating points are basically in the region of low fuel consumption.Under the NEDC conditions,the fuel consumption is 6.9 L/100 km,which achieves the expected control effect The energy management method for hybrid electric vehicle proposed in this paper has certain guiding significance for the development of energy optimization algorithms and the study of coordinated control of working modes of hybrid electric vehicle.更多还原
