To enable an occupant to feel the comfortableness of vehicle acceleration.SOLUTION: A sound generation apparatus for a vehicle includes: a sound control unit 12 for generating a sound signal representing a sound; a speaker 20 for outputting a sound according to the sound signal generated by the sound control unit; and an acceleration state detection unit 13 for detecting that a vehicle 2 is in an acceleration state. When it is detected that the vehicle is in the acceleration state, the sound control unit sets a time transition of a parameter of the sound signal and generates the sound signal on the basis of the time transition of the parameter. The time transition of the parameter includes a repeat of a first trend and a second trend following the first trend. A time until the first trend changes to the second trend for the first time after it is detected that the vehicle is in the acceleration state, and a time interval between each change timing at which the first trend changes to the second trend and the next change timing are set to be the same in a range of 1000 milliseconds or more and 2000 milliseconds or less.SELECTED DRAWING: Figure 7A

    【課題】車両の加速の気持ちよさを乗員に感じさせる。【解決手段】音を表す音信号を生成するように構成された音制御部12と、音制御部により生成された音信号に応じた音を出力するスピーカ20と、車両2が加速状態にあることを検出する加速状態検出部13と、を有し、音制御部は、車両が加速状態にあることが検出された場合、音信号のパラメータの時間推移を設定し、当該パラメータの時間推移に基づき音信号を生成し、パラメータの時間推移は、第1のトレンドと当該第1のトレンドに続く第2のトレンドとの繰り返しを含み、車両が加速状態にあることが検出されてから最初に第1のトレンドが第2のトレンドに変化するまでの時間、及び、第1のトレンドが第2のトレンドに変化する各変化タイミングの時間間隔は、1000ミリ秒以上2000ミリ秒以下の範囲で等しいように設定される。【選択図】図7A
