Kind Code:
A
Abstract:
A direction detecting apparatus is adapted for installation on a vehicle, and includes a first sound collecting unit, a second sound collecting unit, an identifying unit, a direction estimating unit, and a notifying unit. The first and second sound collecting units collect sounds from roads. The identifying unit identifies the types of the sounds collected by the first and second sound collecting units. The direction estimating unit determines whether a warning sound comes from the front when the sound type identified by the identifying unit is a warning sound. The direction estimating unit estimates the direction of the warning sound when the warning sound comes from the front, and estimates a lane in which the warning sound is located when the warning sound comes from behind. The notifying unit is for providing notification of the estimation result of the direction estimating unit.
