To provide a vehicle approach reporting device capable of outputting an alarm sound in which discomfort given to an occupant is reduced.SOLUTION: A vehicle approach reporting device 10 for reporting approach of a vehicle 40 by causing a speaker 30 disposed outside a cabin 41 of the vehicle 40 to output an alarm sound includes a control part 11 for acquiring a travelling speed of the vehicle 40 and controlling sound pressure of the alarm sound output by the speaker 30 according to the acquired travelling speed. The control part 11 estimates first sound pressure, which is sound pressure of a first sound in the cabin 41 of the alarm sound output from the speaker 30, and second sound pressure, which is sound pressure of a second sound in the cabin 41 of road noise by the travelling of the vehicle 40; compares the estimated first sound pressure and second sound pressure: and makes the sound pressure of the alarm sound that the speaker 30 is caused to output smaller when the second sound pressure is changed to a value larger than the first sound pressure as a result of the comparison than when the second sound pressure is the first sound pressure or lower.SELECTED DRAWING: Figure 1

    【課題】搭乗者へ与える不快感を低減した警報音を出力することができる車両近接報知装置を提供する。【解決手段】車両40の車室41外に配置されたスピーカ30に警報音を出力させることで車両40の近接を報知する車両近接報知装置10であって、車両40の走行速度を取得し、取得された走行速度に応じてスピーカ30により出力される警報音の音圧を制御する制御部11を備え、制御部11は、スピーカ30により出力されている警報音の車室41内における第一音の音圧である第一音圧と、車両40の走行によるロードノイズの車室41内における第二音の音圧である第二音圧と、を推定し、推定された第一音圧および第二音圧を比較し、比較の結果、第二音圧が第一音圧より大きい値に変化した場合、第二音圧が第一音圧以下である場合よりも、スピーカ30に出力させる警報音の音圧を小さくする。【選択図】図1
