PROBLEM TO BE SOLVED: To provide a four-wheel-drive vehicular control apparatus that improves responsiveness in switching from a two-wheel-drive state to a four-wheel-drive state in comparison with conventional technique.SOLUTION: When engaging a second engagement clutch 32 after engaging a first engagement clutch 24 in disengaging a disconnect, a second auxiliary 134 of a second actuator 128 applies torque that suppresses a rotation of a central axle 90, causing a second engagement gear-tooth 102b of a second movable sleeve 102 that is connected to the central axle 90 through the second engagement clutch 32 to slow the rotation speed, and therefore a relative rotation speed difference V2 between the second engagement gear-tooth 102b of the second movable sleeve 102 and a second engagement gear-tooth 94c of a second ring gear 94 increases. This in turns improves responsiveness in switching from the disengage state of the second engagement clutch 32 to the engagement state thereof in comparison with conventional techniques, improving the responsiveness in switching from a two-wheel-drive state to a four-wheel-drive state.SELECTED DRAWING: Figure 10

    【課題】従来に比較して2輪駆動状態から4輪駆動状態への切替応答性を向上させる4輪駆動車両の制御装置を提供する。【解決手段】ディスコネクト解除時に、第1噛合クラッチ24の係合後に第2噛合クラッチ32を係合させる場合に、第2アクチュエータ128の第2補助クラッチ134で中央車軸90の回転を抑制するトルクが付与されるので、第2噛合クラッチ32において中央車軸90が連結された第2可動スリーブ102の第2噛合歯102bの回転速度が低下し、その第2可動スリーブ102の第2噛合歯102bと第2リングギヤ94の第2噛合歯94cとの相対回転速度差V2が大きくなる。このため、第2噛合クラッチ32の解放状態から係合状態への切替応答性が従来に比較して向上し、2輪駆動状態から4輪駆動状態への切替応答性が向上する。【選択図】図10
