PROBLEM TO BE SOLVED: To provide a clutch transmission torque learning control device capable of learning clutch transmission torque in vehicle stop, while suppressing occurrence of unexpected vehicle travel for an operator.SOLUTION: In vehicle stop, a clutch transmission torque learning control device controls an engine torque so as to engage each shift stage of transmission mechanisms 12a, 12b of a transmission unit 4 into each maximum stage, and keep an engine rotational frequency into a fixed rotational frequency, while constraining an output shaft 13 by a parking lock mechanism 17. Further, the clutch transmission torque learning control device increases a clutch control value to perform learning of clutch transmission torque.SELECTED DRAWING: Figure 1 【課題】運転者の予期しない車両走行が生じることを抑制しつつ、車両停止時にクラッチ伝達トルクを学習することのできるクラッチ伝達トルク学習制御装置を提供すること。【解決手段】車両停車時に、パーキングロック機構（１７）により出力軸（１３）を拘束した上で、変速ユニット（４）の各変速機構（１２ａ、１２ｂ）の変速段をそれぞれ最高段にギヤ入れし、エンジン回転数を一定回転数に維持するようにエンジントルクを制御しつつ、クラッチ制御値を増加させていくことで、クラッチ伝達トルクの学習を行う。【選択図】図１
