US 10,757,525 B2 · Vehicle and method of controlling the same

Abstract

A vehicle and a method of controlling the vehicle are capable of outputting a sound similar to an original sound by modulating a sound signal obtained using a plurality of microphones of an external terminal device considering the physical characteristics of a user and the sound reproduction space. The vehicle includes: a speaker; a sensor module configured to detect a state of the vehicle; a communicator including a plurality of microphones and configured to receive a sound signal having two channels, information about sensitivity of each microphone of the plurality of microphones, and information about a relative position between the plurality of microphones; and a controller configured to: modulate the sound signal on at least one of the sensitivity of the plurality of microphones, the relative position between the plurality of microphones, and a Head-Related Transfer Function (HRTF); remove the reverberation from the modulated sound signal; and control the speaker.

Dependent claims

A vehicle comprising:

a speaker;
a sensor module configured to detect a state of the vehicle;
a communicator configured to receive, from a terminal apparatus including a plurality of microphones and positioned outside of the vehicle, a sound signal having two channels, information about sensitivity of each microphone of the plurality of microphones, and information about a relative position between the plurality of microphones;
and
a controller configured to:
determine a difference value between the relative position between the plurality of microphones and a predetermined relative position between left and right eardrums;
modulate the sound signal having two channels based on the sensitivity of each microphone of the plurality of microphones, the difference value, a relative position of a sound source with respect to the plurality of microphones, and a Head-Related Transfer Function (HRTF);
remove reverberation corresponding to the state of the vehicle from the modulated sound signal;
and
control the speaker to output the dereverberated sound signal.

A method of controlling a vehicle, the vehicle including a speaker, and a sensor module configured to detect a state of the vehicle, the method comprising:

receiving, from a terminal apparatus including a plurality of microphones and positioned outside of the vehicle, a sound signal having two channels, information about sensitivity of each microphone of the plurality of microphones, and information about a relative position between the plurality of microphones;
determining, by a controller, a difference value between the relative position between the plurality of microphones and a predetermined relative position between left and right eardrums;
modulating, by the controller, the sound signal having two channels based on the sensitivity of each microphone of the plurality of microphones, the difference value, a relative position of a sound source with respect to the plurality of microphones, and a Head-Related Transfer Function (HRTF);
removing, by the controller, the reverberation corresponding to the state of the vehicle from the modulated sound signal;
and
controlling, by the controller, the speaker to output the dereverberated sound signal.
