To provide a vehicle approach notification device capable of reducing cases where a warning sound emitted to outside a vehicle becomes a sound louder than expected.SOLUTION: A vehicle approach notification device 10 makes a loudspeaker 30 output a warning sound, thereby making notification about the approach of a vehicle 40. The vehicle approach notification device 10 includes: a storage unit 12 which stores a prescribed threshold in a sound pressure; and a control unit 11 which, (i) when the sound pressure of the warning sound acquired by a microphone 20 disposed outside the vehicle is the prescribed threshold or less, makes the loudspeaker disposed outside a cabin of the vehicle output the warning sound at a first sound pressure determined according to a vehicle speed of the vehicle, and which, (ii) when the sound pressure of the warning sound acquired by the microphone 20 exceeds the prescribed threshold, makes the loudspeaker 30 output the warning sound at a sound pressure less than the first sound pressure.SELECTED DRAWING: Figure 1

    【課題】車外に対して放射した警報音が想定よりも大きな音になることを低減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】車両近接報知装置10は、警報音をスピーカ30に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、音圧における所定の閾値を記憶している記憶部12と、(i)車両の外側に配置されたマイク20により取得された警報音の音圧が所定の閾値以下の場合、車両の車速に応じて決定した第1の音圧で警報音を車両の車室外に配置されたスピーカに出力させ、(ii)マイク20により取得された警報音の音圧が所定の閾値を超えた場合、第1の音圧よりも小さい音圧で警報音をスピーカ30に出力させる制御部11を備える。【選択図】図1
