APPROACHING VEHICLE DETECTION APPARATUS, AND DRIVE ASSIST SYSTEM

摘要

Provided are a sound source detection device (52) configured to detect sound information around an own vehicle, a sound source detection unit (1d) configured to detect a sound source around the own vehicle based on the detected sound information, an approaching vehicle determination unit (1e) configured to determine whether the sound source is a vehicle approaching the own vehicle, and a vehicle state changing unit (1i) configured to change a vehicle state of the own vehicle to a vehicle state where the own vehicle sound is able to be suppressed when an own vehicle sound generated from the own vehicle is able to be suppressed by changing the vehicle state of the own vehicle. For example, when the own vehicle is able to travel only by a power of an electric generator (12), the vehicle state changing unit (1i) is configured to suppress the own vehicle sound by changing the vehicle state of the own vehicle to a travel state where the own vehicle travels only by the power of the electric generator (12).
