A study on 2-speed transmission of electric vehicle by using inventogram

Abstract

Eco-friendly vehicles, especially electric vehicles, have gained in popularity because of environmental and resource depletion issues. The most important technology regarding electric vehicles is the improvement of the mechanical efficiency of power transmission with limited electric energy resources. To achieve this aim, a transmission that controls torque and speed should be used. In this study, using a new invention method, called 'Inventogram', we developed 2-speed transmission structures and control methods, designed for electric vehicles.
