PROBLEM TO BE SOLVED: To provide a control device of a four-wheel drive vehicle that can suppress abnormal noise and vibrations caused when operating an interrupting device, while suppressing deterioration in responsiveness of the interrupting device which can interrupt transmission of driving force.SOLUTION: An interrupting device 12 that can interrupt driving force to be transmitted to rear wheels 105L and 105R of a four-wheel drive vehicle 1 has: a first rotating member 121 and a second rotating member 122; a sleeve 123 that connects the first rotating member 121 to the second rotating member 122; and an actuator 120 which moves the sleeve 123 in a shaft direction. A control device 9 reduces movement speed of the sleeve 123 in the vicinity of a contact position when moving the sleeve 123 from a stand-by position to the contact position where an engagement tooth 121a of the first rotating member 121 contacts an engagement tooth 123a of the sleeve 123 by controlling the actuator 120.SELECTED DRAWING: Figure 1

    【課題】駆動力の伝達を遮断可能な断続装置の応答性の低下を抑制しながら、断続装置の作動時の異音や振動を抑制することが可能な四輪駆動車の制御装置を提供する。【解決手段】四輪駆動車1の後輪105L,105Rに伝達される駆動力を遮断可能な断続装置12は、第1回転部材121及び第2回転部材122と、第1回転部材121と第2回転部材122とを連結するスリーブ123と、スリーブ123を軸方向移動させるアクチュエータ120とを有する。制御装置9は、アクチュエータ120を制御してスリーブ123を待機位置から第1回転部材121の噛合歯121aとスリーブ123の噛合歯123aとが当接する当接位置に移動させる際、当接位置付近においてスリーブ123の移動速度を減速させる。【選択図】図1
