The present invention relates to an active noise control device for a vehicle, capable of controlling active noise by adapting to changes in driving conditions, an active noise control method thereof, and a vehicle including the same. The active noise control device includes: a sensing unit that senses vehicle vibration, noise, and driving environment; and a control unit that controls active noise by generating a control signal based on the sensed vibration, noise, and driving environment information. The control unit extracts road surface roughness from the driving environment information, updates a convergence coefficient based on the extracted road surface roughness, generates a control signal by reflecting the updated convergence coefficient to a control filter coefficient, and can control active noise using the generated control signal.

    주행 조건 변화에 적응하여 능동 소음을 제어할 수 있는 차량용 능동 소음 제어 장치 및 그의 능동 소음 제어 방법과 그를 포함하는 차량에 관한 것으로, 차량의 진동, 소음, 주행 환경을 센싱하는 센싱부와, 센싱된 진동, 소음, 주행 환경 정보를 토대로 제어 신호를 생성하여 능동 소음을 제어하는 제어부를 포함하고, 제어부는, 주행 환경 정보로부터 노면 거칠기를 추출하고, 추출된 노면 거칠기를 토대로 수렴 계수를 갱신하며, 갱신한 수렴 계수를 제어 필터 계수에 반영하여 제어 신호를 생성하고, 생성된 제어 신호로 능동 소음을 제어할 수 있다.
