To control execution of downshift while releasing an accelerator pedal.SOLUTION: A method includes the steps of: opening an output clutch at a first time point (t1); closing an input clutch at the first time point; completing the opening of the output clutch and the closing of the input clutch at a second time point (t2); synchronizing a rotation speed (ωE) of an internal combustion engine with a rotation speed (ωB) of the input clutch between the second time point and a third time point (t3); and temporarily transmitting a torque greater than a torque (TB) to be transmitted by a clutch to a gear of lower speed immediately after shifting and the torque (TB) greater than a torque (TA) transmitted by the output clutch to a gear of lower speed just before shifting, to the input clutch between the second time point and the third time point.SELECTED DRAWING: Figure 4

    【課題】アクセルペダルが解放される間により低速のギアへのシフトの実行を制御する。【解決手段】第1の時点(t1)に、出力クラッチを開放するステップと、第1の時点に、入力クラッチを閉鎖するステップと、第2の時点(t2)に出力クラッチの開放を完了するとともに、入力クラッチの閉鎖を完了するステップと、第2の時点と第3の時点(t3)との間に、内燃エンジンの回転速度(ωE)を入力クラッチの回転速度(ωB)と同期させるステップと、第2の時点と第3の時点との間で、クラッチがシフト直後により低速のギアに伝達しようとしているトルク(TB)よりも大きく且つシフト直前に出力クラッチがより低速のギアに伝達したトルク(TA)よりも大きいトルク(TB)を入力クラッチに一時的に伝達させるステップとを含む。【選択図】図4
