To facilitate the recognition of a vehicular travel behavior using a notification sound.SOLUTION: A notification sound control apparatus 30 stores plural pieces of sound source data with different frequencies in a sound source 34. A notification sound control circuit 32 determines a vehicular travel behavior from a vehicular speed detected by a vehicular speed sensor 16 and a steering angle detected by a steering-angle sensor 18 and sets a notification sound so as to differentiate frequency, or frequency and sound pressure, in accordance with the determined travel behavior. This technique changes a timber of notification sound pronounced from a speaker 24 in accordance with the vehicular behavior, enabling a pedestrian to easily recognize the vehicular behavior from the timber of the notification sound, thus the notification sound contributing to the safety of the pedestrian.SELECTED DRAWING: Figure 1

    【課題】通報音により車両の走行挙動の認識を容易にする。【解決手段】通報音制御装置30は、音源34に周波数の異なる複数の音源データが格納されており、通報音制御回路32は、車速センサ16により検知される車速、及び舵角センサ18により検知される舵角から車両の走行挙動を判定し、判定した走行挙動に応じて周波数又は周波数と音圧とが異なるように通報音を設定する。これにより、車両の走行挙動に応じて、スピーカ24から発音される通報音の音色が変更されるので、歩行者は、通報音の音色から車両の走行挙動を容易に認識できて、通報音を歩行者の安全性に寄与させることができる。【選択図】図1
