To provide a vehicle approaching object detection system capable of detecting that an approaching object is approaching a vehicle from a blind spot.SOLUTION: A vehicle approaching object detection system is comprised of: a first external sound collecting device, which is arranged in a vehicle and collects a first external sound as a sound of a first range outside the vehicle; a second external sound collecting device that collects a second external sound as a sound in a second range; a frequency detection unit that detects a first frequency, which is a frequency of the first external sound, and a second frequency, which is a frequency of the second external sound; and an approach determination unit that determines a presence or absence of an approaching object approaching a front in a direction of travel of the vehicle, wherein the approach determination unit determines a presence or absence of the approaching object based on a difference between the first frequency and the second frequency detected by the frequency detection unit (S50).SELECTED DRAWING: Figure 3
【課題】接近物が死角から車両に接近していることを検知することができる車両の接近物検知システムを提供する。【解決手段】車両に配設され、車両の外部における第1範囲の音としての第1外部音を集音する第1車外音集音装置と、第2範囲の音としての第2外部音を集音する第2車外音集音装置と、第1外部音の周波数である第1周波数及び第2外部音の周波数である第2周波数を検出する周波数検出部と、車両の進行方向前方に接近する接近物の有無を判定する接近判定部と、を備え、接近判定部は、周波数検出部によって検出した第1周波数及び第2周波数の差に基づいて、接近物の有無を判定する(S50)。【選択図】図3
