In order to increase the energy efficiency of electric vehicles, the research related to controlling traction electric motors and controlling transmission system have been gathering more interest recently. The traditional electric vehicles use a one-speed gearbox. This transmission structure is simple but cannot achieve the best performance because most of the time the electric motor operates at the points where the efficiency is not the highest. Most electric vehicles today use gearboxes with multiple speeds. The transmission systems on traditional cars using internal combustion engines can be used for electric vehicles. In this paper, the author presents the research result on the gearshift strategy of a two-speed dual-clutch gearbox applied on electric vehicles for energy efficiency. The gearshift strategy takes into account the vehicle speed and drag forces.
