摘　　要：混合动力汽车由于能够减少燃油消耗和降低排放而迅速发展。在各种混合动力汽车中,混联式混合动力汽车结合串联和并联混合的优点,其工作模式的优化取决于许多部件,如发动机、电机/发电机、电池和功率分流装置等部件。混联式混合动力汽车控制策略的开发比其他混合动力汽车更复杂。以丰田卡罗拉混合动力汽车为例研究混联式混合动力汽车的能量管理策略。基于对典型驾驶循环的效率分析,提出优化混联式混合动力汽车能量管理的模糊转矩控制策略。建立基于Matlab/simulink的车辆模型,仿真结果表明车辆油耗和性能明显提高。Hybrid electric vehicle(HEV)has developed rapidly because of their ability to reduce fuel consumption and emissions.Among all kinds of HEVs,the series-parallel HEV combines the advantages of series and parallel hybrid.The optimization of its working mode depends on many components,such as engine,motor/generator,battery and power split device.The development of control strategy for the series-parallel HEV is more complex than other HEV.Based on the efficiency analysis of typical driving cycles,a fuzzy torque control strategy is proposed to optimize the energy management of HEV.A vehicle model based on MATLAB/simulink is established.The simulation result shows that the fuel consumption and performance of the vehicle are improved significantly.
