To provide acceleration information via acoustic sense of a driver in a vehicle by outputting sound including a sound source or a music piece representing an acceleration level of acceleration of the traveling vehicle.SOLUTION: A speed meter using sound allows a driver to grasp a travel speed via acoustic sense by allotting speed ranges in which a vehicle is traveling to different sound sources or different music pieces and outputting a current one of them. The speed meter utilizing the acoustic sense adds information of acceleration of the vehicle to the sound sources and the music pieces used in here, to realize functions of: facilitating discrimination difference between the speed ranges; eliminating unnaturalness of the music pieces accompanied by change of the speed ranges; outputting minimum music sought at constant speed travel; and providing the driver with an integrated feeling going along with acceleration feeling allowing the driver to feels as common sensation.SELECTED DRAWING: Figure 6
【課題】走行する車両の加速度の加速レベルを示す音源または楽曲を有する音を出力して、前記車両の運転者の聴覚を介して加速度情報を提供する。【解決手段】車両が走行する速度範囲を異なる音源や楽曲に分担させて出力することで、聴覚により走行速度を運転者に把握させる。ここで用いる音源や楽曲に車両の加速度の情報を付加して、速度範囲の区別の容易化や、速度範囲の変化に伴う楽曲の不自然さの解消や、定速走行時に求められる最小限の楽曲の出力や、運転者が体感として感じる加速度感との一体感を与える機能を持つ聴覚利用の速度計である。【選択図】図6
