摘要
以行星轮系双电机混合动力变速箱为研究对象,利用杠杆原理计算行星轮系在运动中关系和速比,并制定合适的功率分流扭矩分配控制策略,利用SIMULINK自建模型仿真,并对比了eCVT模式与串并联模式的油耗,证实了在合适的控制策略下,具有eCVT模式混动变速箱的经济性要优于仅有串并联模式的混动变速箱。
Two motor gearbox with planetary gear as the research object,the relationship of planetary gear and gear ratio in motion is calculated by using lever principle.Develop appropriate torque split control strategy for power split mode,using SIMULINK to build simulation model,and compared the eCVT mode and series-parallel mode of consumption.It confirmed that under the proper control strategy,the hybrid transmission with eCVT mode is superior to the only serial-parallel mode one.
