Apparatus and method for controlling beamforming microphone considering location of driver seat

摘要

An apparatus for controlling a beamforming microphone considering the location of a driver seat may include: a driver seat sensor configured to sense the location of the driver seat and output the sensed location as a driver seat signal; a directivity control unit configured to calculate a beamforming angle based on the driver seat signal; and a signal processing unit configured to process voice signals outputted from first and second microphones, respectively, and extract and output a voice signal generated from a direction which coincides with the beamforming angle.

1. An apparatus for controlling beamforming in a vehicle, the apparatus comprising:
a driver seat sensor configured to detect a position of the driver seat relative to a longitudinal direction of the vehicle; a controller configured to calculate a beamforming angle of a microphone array based on the position of the driver seat for aligning the beamforming angle with the position of the driver seat and further configured to calculate an angular width around the calculated beamforming angle based on a speed of the vehicle such that the angular width becomes narrower as the speed of the vehicle is higher and such that sound received from within the angular width around the beamforming angle is processed to extract voice signals, wherein the angular width is calculated based on the speed of the vehicle after calculating the beamforming angle based on the position of the driver seat; and a signal processor configured to process voice signals from the microphone array in view of the calculated beamforming angle and the calculated angular width.
