Abstract
A method for providing sound detection information includes steps of: sensing sound around a host vehicle to generate sound data; generating a result of sound detection based on the sound data; calculating a rate of change based on the result of sound detection; generating a result of tunnel detection by comparing the rate of change with a threshold; and controlling at least one peripheral apparatus in the host vehicle according to the result of tunnel detection.

A method for providing sound detection information, comprising steps of:
- sensing sound around a host vehicle to generate sound data;
- generating a result of sound detection including frames consecutive over time based on the sound data;
- calculating a rate of change of peak values of the frames based on the result of sound detection;
- generating a result of tunnel detection by comparing the rate of change with a threshold;
- and
- controlling at least one peripheral apparatus in the host vehicle according to the result of tunnel detection,
- wherein the peak values of the frames, which include previous frames and a present frame, include:
- a first peak value indicating a first angle at which a probability higher than or equal to a certain probability is obtained in a first direction for a first time, the first direction being a direction of gradual increase of the first angle;
- and
- a second peak value indicating a second angle at which a probability higher than or equal to the certain probability is obtained in a second direction for the first time, the second direction being a direction of gradual decrease of the second angle.
