摘要： A vehicle that selectively provides important sound to an occupant includes: a microphone configured to receive a noise sound; a speaker; a storage configured to store a plurality of sound waveforms and a warning sound source corresponding to each sound waveform of the plurality of sound waveforms; and a controller configured to generate a noise canceling signal based on the noise sound, control the speaker to output a noise canceling sound corresponding to the noise canceling signal, compare a waveform of the noise sound with the plurality of sound waveforms when a sound pressure level of the noise sound is greater than a threshold value, and when the waveform of the noise sound matches any sound waveform of the plurality of sound waveforms, and control the speaker to play a warning sound source corresponding to the sound waveform matching the noise sound.

摘要： A vehicle lighting device and a method of controlling luminance thereof are provided. The vehicle lighting device includes a camera module configured to capture an image of the driver's face, a sensing unit configured to detect the surroundings of a vehicle, a lighting unit including at least one light source to illuminate the interior of the vehicle, and a controller. The controller is configured to acquire information on a daytime mode and a nighttime mode through the sensing unit, to acquire information on an infrared brightness level or information on the size of the pupil of the driver's eye based on the image of the driver's face captured by the camera module, and to control the luminance of the lighting unit in response to the acquired information.
