摘要

PROBLEM TO BE SOLVED: To correctly detect a direction of a sound source of a vehicle in a blind area.;SOLUTION: A detection device is arranged in the own vehicle and comprises: a sound collector 102 for collecting external sound; a sound pressure threshold processor 103 that holds a sound pressure threshold at which a sound pressure of a diffraction sound of the vehicle in the blind area becomes larger than a sound pressure of a reflection sound of the vehicle in the blind area, and determines whether the sound pressure of the external sound collected by the sound collector 102 is larger than the sound pressure threshold; and a vehicle detector 105 for detecting the direction of the sound source of the vehicle in the blind area from the external sound collected by the sound collector 102, when the sound pressure threshold processor 103 determines that the sound pressure of the external sound is larger than the sound pressure threshold.;COPYRIGHT: (C)2012,JPO&INPIT
