To provide a danger notification system that notifies a driver of a danger by causing a high-frequency sound to be outputted through earphones which are worn by the driver, before an alarm sound is emitted.SOLUTION: A danger notification system 1 includes sound collection microphones 200 that are disposed symmetrically at positions in the vehicle width direction and the vehicle length direction on the flanks of a vehicle, where the microphones are unsusceptible to travel environment sounds, earphones 300 worn by at least a driver, a controller 100 that, when a relative change is found in a high-frequency sound around the vehicle which is collected by the sound collection microphone 200, causes a high-frequency sound to be outputted through the earphone 300 in a direction in which the relative change is found, and a notification unit 500 that provides notification of a danger.SELECTED DRAWING: Figure 5
【課題】警告音を発する前に、運転者が装着するイヤホンから高周波の音声を出力させることにより、運転者に危険を察知させる危険報知システムを提供する。【解決手段】危険報知システム1は、車両側面の車幅方向および車長方向において、走行環境音の影響を受けにくい箇所に対称に設けられた収音マイク200と、少なくとも運転者が装着するイヤホン300と、収音マイク200において収音された車両周辺の高周波の音に相対変化があった場合に、相対変化があった方向のイヤホン300に高周波の音声を出力させる制御装置100と、危険を報知する報知装置500と、を備えている。【選択図】図5
