The present invention relates to an apparatus for generating virtual engine sound of a vehicle, and a generation method thereof, which can play sound sources and volume with appropriate sound corresponding to a vehicle speed. To this end, according to the apparatus and the generation method in accordance with one aspect of the present invention, frequency of the sound sources can be exponentially changed in accordance with a change in a vehicle speed to output virtual engine sound. Therefore, sound sources of the frequency range corresponding to the vehicle speed can be overlapped instead of being disconnected even when a plurality of sound sources are used. Accordingly, volume of a section in which the sound sources are overlapped in accordance with a vehicle speed is corrected to play sound sources and volume of sound suitable for the vehicle speed. By doing so, a pedestrian can more definitely recognize approach of a vehicle.

    본 발명은 차량 속도에 대응하는 적절한 사운드의 음원과 음량을 재생할 수 있는 차량의 가상 엔진음 생성 장치 및 그 방법을 제안한다. 이를 위해 본 발명의 일 측면에 의한 차량의 가상 엔진음 생성 장치 및 그 방법에 의하면, 차량의 속도 변화에 따라 음원의 주파수를 지수적으로 변경시켜 가상 엔진음을 출력함으로써 복수의 음원을 사용하여도 차량 속도에 대응하는 해당 주파수 대역의 음원이 단절되지 않고 오버랩시킬 수 있다. 이에 따라 차량 속도에 따라 복수의 음원이 오버랩되는 구간의 음량을 보정하여 차량 속도에 적절한 사운드의 음원과 음량을 재생함으로써 보행자로 하여금 차량의 접근을 보다 확실하게 인식할 수 있도록 한다.
