To issue a notification sound effectively enabling a pedestrian and the like to pay attention to.SOLUTION: In a notification sound control apparatus 30, detecting a pedestrian by a camera 12 and an obstacle detection sensor 14, a notification sound control circuit 32 sets a notification sound with frequencies continuously changed with a given frequency range and issues the set notification sound. This technique, using the notification sound changing its timber characteristically, effectively enables a pedestrian, to which the vehicle itself approaches, to pay attention.SELECTED DRAWING: Figure 1
【課題】歩行者などに効果的に注意喚起通できる通報音を発する。【解決手段】通報音制御装置30は、カメラ12及び障害物検知センサ14により歩行者が検知されると、通報音制御回路32が所定の周波数範囲内で周波数を連続的に変化させた通報音を設定し、設定した通報音を発音させる。これにより、音色が特徴的に変化する通報音により自車両が接近する歩行者に対して効果的に注意喚起できる。【選択図】図1
