PROBLEM TO BE SOLVED: To enable a driver to hear a notification sound in a sure manner even when the magnitude of a driving environment sound changes.SOLUTION: Music reproduced inside a vehicle is amplified at an amplification rate as set by a driver, and is output to acoustic equipment. To output a notification sound while music is reproduced, the amplification rate is acquired, and after the amplification rate is reduced or output of the music is interrupted, the notification sound is output from a notification sound output part at a determined sound volume based on the acquired amplification rate. Thereby, since the magnitude of a driving environment sound is reflected in the amplification rate as set by the driver, the volume of the notification sound can be appropriately set according to the magnitude of the driving environment sound without actually measuring the magnitude of the driving environment sound. As a result, even when the magnitude of the driving environment sound changes, the driver can hear the notification sound in a sure manner without confusing the notification sound with the driving environment sound.SELECTED DRAWING: Figure 3
【課題】運転環境音の大きさが変化しても、運転者に報知音を確実に聞き取らせることを可能にする。【解決手段】車両の室内で再生される楽曲を、運転者による設定に応じた増幅率で増幅して音響機器に出力する。そして、楽曲の再生中に報知音を出力する場合には、増幅率を取得して、増幅率を低減または楽曲の出力を遮断させた後、取得した増幅率に基づいて決定した音量で報知音を報知音出力部から出力させる。こうすれば、運転者による設定に応じた増幅率には運転環境音の大きさが反映されているので、運転環境音の大きさを実際に計測しなくても、運転環境音の大きさに応じて報知音の音量を適切に設定することができる。その結果、運転環境音の大きさが変化しても、運転環境音に報知音が紛れてしまうことがなく、報知音を運転者に確実に聞き取らせることが可能となる。【選択図】図3
