1. A method for implementing virtual internal combustion engine vibration in an electric vehicle, the method comprising:
collecting operation variable information for determining a torque instruction and implementing the virtual internal combustion engine vibration while the electric vehicle travels;
determining a virtual internal combustion engine vibration characteristic based on the collected operation variable information;
determining a vibration torque instruction having the determined virtual internal combustion engine vibration characteristic;
correcting the vibration torque instruction by correcting the determined virtual internal combustion engine vibration characteristic of the vibration torque instruction and/or a value of the vibration torque instruction, based on a basic motor torque instruction determined by the collected operation variable information and a preset backlash occurring area information;
determining a final motor torque instruction using the basic motor torque instruction and the corrected vibration torque instruction; and
controlling an operation of a driving motor of the electric vehicle according to the determined final motor torque instruction.
