Abstract:
The vehicle location detection device includes: a sound source location specifying unit which calculates an attenuation amount of a sound pressure of a vehicle sound by subtracting a sound pressure detected by a sound pressure detecting unit from a sound pressure indicated by vehicle sound pressure information stored in a sound pressure information storage unit, and specifies a location where another vehicle emitting a vehicle sound is predicted to be present, by specifying a sound source location of a sound diffracted by an obstacle which is specified by a diffraction location specifying unit and serves as a diffraction point, based on the calculated attenuation amount, a rule indicating an attenuation amount dependent on a propagation distance of the sound, and a relationship indicated by diffraction information stored in a diffraction information storage unit; and a presentation unit which presents the specified location.
