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.
