Abstract
In order to improve the economy and power of electric vehicles,an electronically controlled mechanical automatic transmission control system is designed.By designing the transmission structure,matching and optimising the transmission ratio,proposing the optimal shifting law and verifying it through experiments under different working conditions,establishing the control model of the shifting system,and carrying out the research on the synergistic control of the electric motor and transmission,we have achieved the purpose of improving the performance of the electric vehicle and laid a foundation for the further optimisation of the subsequent transmissions.
