A method and a device for active noise control of a vehicle are disclosed to reduce the noise perceived by occupants during driving. According to one aspect of the present invention, there is provided a computer-implemented method for active noise control of a vehicle, comprising the steps of: obtaining an occupant distribution for at least one occupant; estimating sound transmission characteristics between the generation point of a noise control signal for controlling noise and the measurement point of an error signal indicating residual noise by considering the occupant distribution; generating a noise control signal from a reference signal of a sensor and the error signal based on the sound transmission characteristics; and controlling the output of the noise control signal.

    차량의 능동 소음 제어 방법 및 장치를 개시한다. 본 발명의 일 측면에 의하면, 차량의 능동 소음 제어를 위한 컴퓨터 구현 방법에 있어서, 적어도 하나의 탑승자에 관한 탑승자 분포를 획득하는 단계; 상기 탑승자 분포를 고려하여, 소음을 제어하는 소음 제어 신호의 생성 지점과 잔여 소음을 나타내는 오차 신호의 측정 지점 사이 음향 전달 특성을 추정하는 단계; 상기 음향 전달 특성에 기초하여 센서의 참조 신호 및 상기 오차 신호로부터 소음 제어 신호를 생성하는 단계; 및 상기 소음 제어 신호의 출력을 제어하는 단계를 포함하는 방법을 제공한다.
