PROBLEM TO BE SOLVED: To provide a control device of an engine mount which can suppress that an occupant feels incongruity resulting from the resonance of vibration which is transmitted to a vehicle from a road face when an engine rotation number is low, and the vibration of an engine.SOLUTION: An electronic control device switches a spring characteristic of an engine mount to a first spring characteristic and a second spring characteristic according to engine torque Trq when an engine rotational speed NE is lower than a determination value HR. Concretely, when the engine rotation number NE is lower than the determination value HR, and the engine torque Trq is equal to or higher than a determination value HT, the electronic control device valve-opens a VSV so that the spring characteristic of the engine mount is switched to the first spring characteristic. Also, when the engine rotation number NE is lower than the determination value HR, and the engine torque Trq is lower than the determination value HT, the electronic control device valve-closes the VSV so that the spring characteristic of the engine mount becomes larger than the first spring characteristic in an attenuation coefficient c, and a spring constant k is switched to the second spring characteristic.SELECTED DRAWING: Figure 3

    【課題】エンジン回転速度が低いときの路面から車両に伝達される振動とエンジンの振動との共振に起因して乗員が不快感を覚えることを抑制できるエンジンマウントの制御装置を提供する。【解決手段】電子制御装置は、エンジン回転速度NEが判定値HR未満であるとき、エンジントルクTrqに応じてエンジンマウントのばね特性を第1ばね特性と第2ばね特性との間で切り替える。詳しくは、エンジン回転速度NEが判定値HR未満であり、且つ、エンジントルクTrqが判定値HT以上であるとき、エンジンマウントのばね特性が第1ばね特性に切り替えられるようVSVを開弁させる。また、エンジン回転速度NEが判定値HR未満であり、且つ、エンジントルクTrqが判定値HT未満であるとき、エンジンマウントのばね特性が上記第1ばね特性よりも減衰係数cが大きく且つばね定数kが大きい第2ばね特性に切り替えられるようVSVを閉弁させる。【選択図】図3
