摘要
针对混合动力汽车仿真软件ADVISOR中原有制动力分配策略的不足,在其再生制动模型基础上,从动力学角度建立了各制动力制动份额随载荷变化的模型,并将所提出的策略在AD-VISOR软件中对哈飞样车进行了仿真。仿真结果表明所提出的控制策略回收制动能量的效果优于原有的再生制动控制策略,排放也有所改善,电机效率明显提高,同时这种分配方式也符合制动力法规的分配要求;并通过试验进一步验证了该策略的合理性。此模型有效地拓展了ADVISOR的仿真范围,方便了对混合动力电动汽车的研究。
On account of the deficiency of the original share strategy of braking force in HEV simulation software ADVISOR,based on the regenerative braking control model,a new model in which the braking share of every braking force varies on the change of loading was built from the dynamical standpoint.Simulation is done with the use of ADVISOR in HAFEI automobile.The simulation analysis shows that the effect about energy resaving in new control strategy is better than in old strategy,the emission has been improved.The motor efficiency has been obviously increased.At the same time,the kind of sharing manner is also in accordance with the sharing requirement of the rule about braking force.The model effectively expands the simulation range of ADVISOR,give convenience to the HEV research.
