PROBLEM TO BE SOLVED: To provide an AMT which comprises a non-synchronous transmission, and can reduce a possibility that "up-lock" occurs at a "second position" of a sleeve.SOLUTION: A rotational speed Ni of an input shaft of a transmission is adjusted so as to coincide with a "synchronous rotational speed" by the adjustment of Te in a state that clutch torque Tc is maintained at a value larger than the engine torque Te (t3 to t4) after achieving a neutral stage by releasing the engagement of an idling gear and a corresponding sleeve S1 when a gear change requirement is issued to a non-synchronous stage (t3). When the sleeve S1 reaches a "first point" (point) (t5), the Te is transited in a state that the synchronization of the Ni is maintained by the adjustment of the Te (on and after t4). By this constitution, since the sleeve S1 passes a "second position" (point B) in a state that engaged faces of the sleeve S1 and dog teeth of the idling gear are made to stick to each other, "up-lock" hardly occurs.SELECTED DRAWING: Figure 7

    【課題】ノンシンクロトランスミッションを備えたAMTであって、スリーブの「第2位置」での「アップロック」が発生する可能性を低減し得るものを提供すること。【解決手段】ノンシンクロ段への変速要求があった場合、変速前の変速段の遊転ギヤと対応するスリーブS1との係合を解除してニュートラル段を実現した後(t3)、クラッチトルクTcをエンジントルクTeより大きい値に維持した状態(クラッチの接合状態)で、Teの調整によって変速機の入力軸の回転速度Niが「同期回転速度」に一致するように調整される(t3〜t4)。Teの調整によってNiの同期が維持された状態(t4以降)において、スリーブS1が「第1位置」(点A)に達すると(t5)、Teが変移させられる。これにより、スリーブS1及び遊転ギヤのドグ歯の噛合い面同士を張り付かせた状態でスリーブS1が「第2位置」(点B)を通過するので、「アップロック」が発生し難い。【選択図】図7
