Disclosed is an acoustic alerting system for a vehicle. According to one embodiment of the present invention, the acoustic alerting system for a vehicle outputs virtual engine sound by a speaker. The acoustic alerting system for a vehicle comprises: a vehicle state sensor unit detecting an operation state of a vehicle; an acoustic source storage unit in which virtual engine sound in accordance with the vehicle operation state is stored in a shape of a digital acoustic source; an acoustic control unit outputting a digital acoustic source of virtual engine sound corresponding to the vehicle operation state detected through the vehicle state sensor unit among the virtual engine sound stored in the acoustic source storage unit; and a full digital amplifier unit allowing the digital acoustic source outputted from the acoustic source control unit in accordance with a control signal of the acoustic source control unit to be changed to a PWM signal to be amplified so as to be outputted by the speaker.

    차량 음향 경보 시스템이 개시된다. 본 발명의 일실시예에 따른 차량 음향 경보 시스템은 가상 엔진 사운드를 스피커로 출력하는 차량 음향 경보 시스템에 있어서, 차량의 작동 상태를 감지하는 차량 상태 감지부와, 차량의 작동 상태에 따른 가상 엔진 사운드가 디지털 음원 형태로 저장된 음원 저장부와, 차량 상태 감지부를 통해 감지된 차량 작동 상태에 따라 음원 저장부에 저장된 가상 엔진 사운드 중 그에 대응하는 가상 엔진 사운드의 디지털 음원을 출력하는 음원 제어부와, 음원 제어부의 제어신호에 따라 음원 제어부로부터 출력된 디지털 음원을 PWM 신호로 변환하여 증폭하여 스피커로 출력하는 풀 디지털 앰프부를 포함하는 차량 음향 경보 시스템. 포함한다.
