To provide an approaching object detection system of a vehicle, that is capable of detecting that an approaching object approaches a vehicle from a dead angle.SOLUTION: An approaching object detection system of a vehicle comprises: a vehicle exterior sound collection device arranged in a vehicle and for collecting an exterior sound as a sound outside the vehicle; a frequency detection part for detecting frequencies (H1, H2) of the exterior sound collected by the vehicle exterior sound collection device; and an approach determination part for determining presence/absence of an approaching object (101) approaching in front of a travel direction of the vehicle. The approach determination part determines the presence/absence of the approaching object based on frequency change of the exterior sound detected by the frequency detection part (S50) at a fixed time (Δt) (S40).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、該車両の外部の音としての外部音を集音する車外音集音装置と、車外音集音装置によって集音された外部音の周波数(H1,H2)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(101)の有無を判定する接近判定部と、を備え、接近判定部は、一定時間(ΔT)における(S40)、周波数検出部によって検出した外部音の周波数の変化に基づいて、接近物の有無を判定する(S50)。【選択図】図3
