基于成本优化的插电式混合动力参数匹配

Parameter matching for plug-in hybrid electric vehicle based on cost optimization

在满足整车性能约束条件的基础上,以整车动力部件制造成本和年均使用成本作为评价指标,建立了插电式混合动力汽车（PHEV）动力总成设计分析模型,根据不同类型用户的用车习惯进行分类,针对不同的纯电动续驶里程（AER）设计要求,优化整车动力总成性能参数。结果表明：各设计要求的PHEV总年均优化成本与原车型相比降低了6.0%-20.0%,并优选得到AER最佳设计要求为40km,与其他各AER及原车型相比,在不同续驶里程分布规律下,其年均优化成本最高可降低24.9%。

To meet the vehicle performance constraints,a design and analysis model of the powertrain of Plug-in Hybrid Electric Vehicle（PHEV）was proposed.In this model the manufacturing cost of the vehicle dynamic components and the annual usage cost were taken as the evaluation indices,and the car users＇ habits were classified.According to different design requirements of All-electric Range（AER）,the powertrain performance parameters of PHEV were optimized.The results show that,compared with the original vehicle,the total annual optimization cost of the designed PHEV for different AER is reduced by 6.0% -20.0%.The best optimization design requirement for AER is 40 km.Compared with other AER and the original vehicle,the annual optimization cost can be reduced by up to 24.9%.
