Method of virtualizing characteristics of internal combustion engine vehicle in electric vehicle

A method of virtualizing characteristics of an internal combustion engine vehicle in an electric vehicle, the method comprising:

• obtaining, by a controller, powertrain state information for a vehicle powertrain including a motor that makes a vehicle move and a power transmission device between the motor and driving wheels;
• determining, by the controller, tooth surface pressures of gears in the powertrain between the motor and the driving wheels based on the obtained powertrain state information;
• 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.
