An
active control system of a vehicle dual
microphone formed by a first
microphone (510) and a second
microphone (520), the
control system comprising: a
mouth shape change detection unit (100) installed in a vehicle and configured to capture an image of a driver sitting in a driver's seat of the vehicle and / or a passenger sitting in a passenger's seat and detect a change in the
mouth shape of the driver and / or the passenger; a user and seat position detection unit (200) configured to detect driving state information of the driver and / or the passenger; an infotainment
system (300) configured to determine a microphone
beamforming control mode according to the captured image or images and the driving state information output by the
mouth shape change detection unit (100) and the user and seat position detection unit (200), to control a microphone
beamforming of the first microphone (510) installed adjacent to the driver's seat according to the determined microphone
beamforming control mode, and to selectively adjust a specific microphone
gain according to the determined microphone beamforming
control mode to separately control the microphone beamforming of the first microphone (510) and the second microphone (520) installed adjacent to the passenger seat; and a microphone beamforming controller (400) configured to adjust an installation angle of the first microphone (510) installed adjacent to the driver's seat to be directed toward the driver, or installation angles of the first microphone (510) and the second microphone (520) installed adjacent to the driver's seat and the passenger's seat to be directed toward the driver and the passenger, respectively, according to the control of the infotainment
system (300), wherein the user and seat position detection unit (200) includes: a first
database (210) configured to store and manage the driving state information including selective seat height information of the driver or the front passenger, seat position information of the driver's seat or the front passenger's seat of the vehicle using a
database method according to the control of the infotainment system (300); a first controller (220) configured to store or read the driving state information stored in the first
database (210) according to the control of the infotainment system (300); and a second
network communication unit (230) configured to transmit the driving state information to the infotainment system (300) according to the control of the first controller (220).
