摘要

针对一种重度混合动力汽车驱动系统结构,制定了参数匹配的性能指标,提出了混合度的概念;通过对动力源总功率和各性能指标的计算与分析,得出了整车质量对整车性能的影响,在此基础上,对混合度的上下限值进行了计算;在ADVISOR（Advanced VehIcle SimulatOR）快速仿真平台基础上,搭建了基于NEDC循环工况的仿真模型,仿真并分析了不同混合度对整车动力性和经济性的影响。仿真结果表明,随着混合度的增大,整车经济性越来越好,而整车的动力性能却逐渐降低;根据整车油耗与混合度的关系,采用二次线性拟合的方法,确定了混合度的最优值,并在此基础上,完成了对整车传动系各部件相关性能参数的匹配。

Abstract

The performance indexes of parameter matching are formulated and the concept of degree of hybridization is put forward based on a kind of driving system of hybrid electric vehicle,the effect of vehicle mass on vehicle performance is obtained by the calculation and analysis of the total power of power source and performance indexes.On this basis,the upper limit and lower limit of the degree of hybridization are calculated,on the basis of ADVISOR simulation platform,the simulation model based on NEDC cycle is built up,the simulation and analysis of the effect between different degree hybridization on the dynamic performance and fuel economy performance of the vehicle are accomplished.The results show that the fuel economy gets better and better along with the degree of hybridization increasing,but the dynamic performance of the vehicle gets worse gradually.According to the relationship between the fuel consumption of the vehicle and the degree of hybridization,the optimum degree of hybridization is confirmed by using twice linear fitting method,besides,the relevant parameter matching of the transmission is accomplished.
