In order to solve the problem that the transmission parameter matching rate of traditional hybrid electric vehicles is too low,on the basis of clarifying the structure of the hybrid electric vehicle transmission system,a hybrid electric vehicle transmission parameter matching and optimization method was designed.By selecting the hybrid electric vehicle generator,calculating the speed ratio of the hybrid electric vehicle transmission system,matching the transmission parameters of the hybrid electric vehicle,and adopting the method of electric auxiliary control to realize the optimization of the transmission parameters of the hybrid electric vehicle.The design case analysis shows that the matching rate of the hybrid electric vehicle transmission parameters of the design method is 71%at the highest and 50%at the lowest,while the matching ratio of the control group is 26%at the highest and only 10%at the lowest.Therefore,the design method is significantly higher than the control group.It can solve the problem of too low matching rate of transmission parameters of traditional hybrid electric vehicles.
