の駆動系クラツチ制御装置。[Scope of Claim for Utility Model Registration] A drive system clutch means provided in the middle of the engine drive system that transmits engine driving force to the front and rear wheels, and that directly connects the front and rear wheels to a driving state using an external clutch engagement force, and at least a brake operation. and a clutch control means that outputs a control signal that increases or decreases the clutch engagement force based on input signals from a plurality of detection means including a brake operation detection means that detects the state, and reduces the clutch engagement force when the brake is operated. In a vehicle drive system clutch control device, the detection means includes an acceleration operation detection means that detects an acceleration operation in addition to a brake operation detection means that detects a brake operation; 1. A drive system clutch control device for a four-wheel drive vehicle, characterized in that the device performs control to prohibit a reduction in clutch engagement force when an acceleration operation is detected.
