To provide a vehicular acoustic control device capable of controlling a sound generated in the cabin of a vehicle to an optimum state for grasping a driving state.SOLUTION: A vehicular acoustic control device comprises: emphasis engine degree determination means 6 which determines an emphasized degree component of an engine sound to be emphasized corresponding to an engine rotating speed of a vehicle detected by engine rotating speed detection means according to a characteristic map in which a degree component of an engine sound to be emphasized is made to correspond to the engine rotating speed on the basis of human's auditory characteristics for a pitch of a sound; and in-cabin sound control means 7 which controls an in-cabin sound generated by in-cabin sound generation means 4 so that a passenger of the vehicle easily recognizes the determined emphasis degree component. The in-cabin sound control means 7 emphasizes the emphasis degree component of the engine through generation of a sound in phase with the emphasis degree component, generation of a phase opposite to an engine degree component other than the emphasis degree component, etc.SELECTED DRAWING: Figure 1
【課題】 車両の車室内に発生する音響を運転状態の把握に最適な状態に制御し得る車両音響制御装置を提供する。【解決手段】 人間の音の高さに対する聴覚特性に基づいて車両のエンジン回転数に対して強調すべきエンジン音の次数成分を対応づける特性マップにしたがって、前記エンジン回転数検出手段により検出されたエンジン回転数に対応して強調すべきエンジン音の強調次数成分を決定する強調エンジン次数決定手段6と、決定された強調次数成分が車両の乗員に認識されやすいように車室内音発生手段4により発生される車室内音を制御する車室内音制御手段7とを備える。車室内音制御手段7は、強調次数成分と同位相の音の発生、強調次数成分以外のエンジン次数成分と逆位相の発生等により、エンジンの強調次数成分を強調する。【選択図】 図1
