1. A virtual engine sound generation system comprising:
a control unit for generating a virtual RPM signal based on received vehicle state information and a preset vehicle parameter; and
a virtual engine sound generation unit for generating a virtual engine sound based on the vehicle state information and the virtual RPM signal, to be produced through a sound output unit;
wherein the control unit calculates a virtual gear stage based on the vehicle state information and a gear shift pattern and generates the virtual RPM signal based on a preset transmission gear ratio corresponding to the calculated virtual gear stage.
