VEHICLE SOUND GENERATION DEVICE

To provide a vehicle sound generation device that outputs a sound that allows a driver to perform an accurate accelerator operation suitable for the travel situation of a vehicle.SOLUTION: A vehicle sound generation device 1 includes: a sound control unit 12 that sets a plurality of frequencies corresponding to the number of rotations of a motor and sound pressure applied to each of the frequencies, and generates a synthetic sound signal representing a synthetic sound including sounds of the plurality of frequencies to which the set sound pressure is applied; a speaker 20 that outputs the synthetic sound based on the synthetic sound signal generated by the sound control unit 12; and a travel situation estimation unit 13 that estimates a first travel situation in which a driver slowly accelerates and decelerates the vehicle and a second travel situation in which the driver suddenly accelerates and decelerates the vehicle. The sound control unit 12 changes the magnitude of the sound pressure applied to each of the frequencies when the first or second travel situation is estimated and when the first and second travel situations are not estimated.SELECTED DRAWING: Figure 2 【課題】ドライバが車両の走行状況に適した正確なアクセル操作を行えるような音を出力する車両用音生成装置を提供する。【解決手段】車両用音生成装置１は、モータ回転数に応じた複数の周波数と、この複数の周波数のそれぞれに適用する音圧とを設定し、この設定された音圧がそれぞれ適用された複数の周波数の音を含む合成音を表す合成音信号を生成する音制御部１２と、音制御部１２が生成した合成音信号に基づいて合成音を出力するスピーカ２０と、ドライバが車両を緩やかに加減速させるような第１走行状況及びドライバが車両を急に加減速させるような第２走行状況を推定する走行状況推定部１３を有する。音制御部１２は、第１又は第２走行状況が推定された場合と、第１及び第２走行状況が推定されなかった場合とで、複数の周波数のそれぞれに適用する音圧の大きさを変える。【選択図】図２
