1. A method of virtualizing characteristics of an internal combustion engine vehicle in an electric vehicle, the method comprising:
determining, by a controller, a current input torque applied to a powertrain from a motor that makes a vehicle move;
determining, by the controller, tooth surface pressures of gears in the powertrain between the motor and driving wheels from the determined current input torque;
generating, by the controller, a virtual effect signal for generating a virtual effect that simulates powertrain characteristics of the internal combustion engine vehicle based on the determined tooth surface pressures of the gears in the powertrain; and
generating, by the controller, the virtual effect that simulates the powertrain characteristics of the internal combustion engine vehicle by controlling operation of a virtual effect generation device that generates the virtual effect according to the generated virtual effect signal,
wherein the determining tooth surface pressures of gears in the powertrain comprises:
determining that a current state of the gears in the powertrain is one of a backlash state and a normal state according to the determined current input torque; and
in response to determination that the current state is the normal state, determining the tooth surface pressures of the gears in the powertrain as a value corresponding to the current input torque.
