To solve the problem that time lag may occur before a cooling fan stops, in a case of trying to stop the rotation of the cooling fan attached to a rotational shaft of an internal combustion engine through a fan clutch.SOLUTION: A vehicle is equipped with an electric fan driven by an electric motor, and a mechanical fan driven in conjunction with an internal combustion engine via a fan clutch. When a required air volume is less than a predetermined value, while the electric motor is driven, the fan clutch is switched to a non-engaged state to drive only the electric fan. When the required air volume is eqaul to or above the predetermined value, the electric motor is driven and the fan clutch is switched to an engaged state, to control both the electric fan and the mechanical fan to be driven.SELECTED DRAWING: Figure 4 【課題】ファンクラッチを介して内燃機関の回転軸に取り付けられた冷却ファンの回転を停止させようとした場合、冷却ファンが停止するまでの間にタイムラグが生じてしまう。【解決手段】電動モータで駆動する電動ファンとファンクラッチを介して内燃機関と連動して駆動する機械式ファンとを車両に搭載する。要求風量が所定値未満のときには、電動モータを駆動するとともにファンクラッチを非係合状態に切り替え、電動ファンのみを駆動させる。要求風量が所定値以上のときには、電動モータを駆動するとともにファンクラッチを係合状態に切り替え、電動ファン及び機械式ファンを共に駆動させるように制御する。【選択図】図４
