摘　　要：为了分析混合动力系统的换挡过程,本文基于AMESim仿真软件,建立了一种新型行星齿轮插电式并联混合动力系统。利用模拟方法对换挡参数进行标定,分析了升、降换挡过程包含的高挡转矩相、档位切换阶段、惯性相、低挡转矩相4个阶段,并借助AMESim软件进行仿真模拟。仿真结果表明,发动机转速变化较为舒缓,发动机与离合器搭接过程平滑,最大换挡冲击度在合理范围内,说明该新型混合动力系统对换挡冲击的控制效果良好,换挡品质较好,同时整个换挡过程实现了动力无中断,平滑换挡。该研究对节能环保具有重要的现实意义。In this paper,a new electric parallel hybrid power system with planetary gears is presented.In order to analyze the shifting process of the power system,the new hybrid powertrain system model is set up and validated by using AMESim simulation software.The shifting parameters are coordinated by using simulating method.Up shift and down shift processes are investigated in 4 phases including higher speed torque exchange phases,shifting phases,inertia phases,lower speed torque exchange phases.The results show that the new hybrid power system designed can achieve smooth shiftwithout power interruption and shifting impact within reasonable bound.The research has important practical significance for energy conservation and environmental protection.
