駆動系クラツチ制御装置。[Scope of Claim for Utility Model Registration] A drive system clutch means that is provided in the middle of an engine drive system that distributes and transmits engine driving force to front and rear wheels or left and right wheels, and that can change the transmission torque by external clutch engagement force; A drive system clutch control device comprising a clutch control means for outputting a control signal for increasing or decreasing a clutch engagement force based on a rotational speed difference detected from a rotational speed difference detection means between a wheel or left and right wheels, wherein the clutch control means is provided with an accelerator. A control period variable means is provided that shortens the control period when the accelerator opening change rate detected by the opening change rate detection means is small on the deceleration side or acceleration side, and lengthens the control period when the accelerator opening change rate is large on the acceleration side. A drive system clutch control device characterized by:
