PROBLEM TO BE SOLVED: To reduce a notification sound noise to a crew member as a vehicle approach notification device mounted on an electric automobile or a hybrid automobile.SOLUTION: The vehicle approach notification device includes: a notification sound signal output part for generating and outputting a notification sound signal as a voice signal to be supplied to an out-of-vehicle speaker which outputs a vehicle approach notification sound to the outside of a vehicle; and a cancellation signal generation part for generating a cancellation signal by making the phase of the notification sound signal to be output by the notification sound signal output part into an antiphase as a voice signal to be supplied to an in-cabin speaker, and output as a voice. Thus, a notification sound to be transmitted through the cabin is cancelled by the cancellation signal.

    【課題】電気自動車やハイブリッド自動車などに搭載される車両接近通報装置として、乗員に対する通報音ノイズを低減する。【解決手段】車両の外部に向けて車両接近通報音を出力する車外用スピーカに供給する音声信号として、通報音信号を生成して出力する通報音信号出力部と、車室内スピーカに供給して音声出力させる音声信号として、通報音信号出力部から出力される通報音信号を逆位相としたキャンセル信号を生成するキャンセル信号生成部とを備える。キャンセル信号により、車室内に透過してくる通報音がキャンセルされるようにする。【選択図】図2
