THE DESIGN OF AUTOMATIC TRANSMISSION CONTROL SYSTEM OF ELECTRIC VEHICLE

The battery and motor technology is not enough mature,so electric vehicles still need transmissions to improve its performance.The structure,working principle,advantage and disadvantage of common automatic transmissions are introduced.Considering the characteristics of electric vehicle motor and the advantages of double clutch automatic transmission,we propose two block double clutch transmission in electric vehicle.Particularly,we introduce the basic structure,working principle,realization process and advantages of the automatic transmission.The research results show that this automatic transmission has a good application prospect
