To achieve both the improvement of the control accuracy of an engine rotating speed and the improvement of drivability according to the operation state of an engine during the shifting of a mechanical transmission mechanism.SOLUTION: When the operation state of an engine 14 is a state of being stopped or a state of warming up a catalyst, as compared to when the operation state of the engine 14 is a state of being normally operated, an engagement hydraulic pressure PRcb of an engaging side engagement device is lowered in the shifting transition of a stepped transmission part 20, so that an engine rotating speed is less likely to vary relative to target rotation. As a result, in the shifting of the stepped transmission part 20 when the operation state of the engine 14 is the state of being stopped or the state of warming up the catalyst, the engine rotating speed can be accurately controlled. In addition, in the shifting of the stepped transmission part 20 when the operation state of the engine 14 is the state of being normally operated, a shifting time can be reduced. Thus, during the shifting of the stepped transmission part 20, the improvement of the control accuracy of the engine rotating speed and the improvement of drivability can be both achieved according to the operation state of the engine 14.SELECTED DRAWING: Figure 7
【課題】機械式変速機構の変速の際に、エンジンの作動状態に合わせて、エンジン回転速度の制御精度の向上とドライバビリティの向上とを両立する。【解決手段】エンジン14の作動状態が停止中又は触媒暖機中である場合は、エンジン14の作動状態が通常運転中である場合と比べて、有段変速部20の変速過渡において係合側係合装置の係合油圧PRcbが低くされるので、エンジン回転速度が狙いの回転に対して変動し難くなる。これにより、エンジン14の作動状態が停止中又は触媒暖機中のときの有段変速部20の変速では、エンジン回転速度を精度良く制御することができる。又、エンジン14の作動状態が通常運転中のときの有段変速部20の変速では、変速時間を短縮することができる。よって、有段変速部20の変速の際に、エンジン14の作動状態に合わせて、エンジン回転速度の制御精度の向上とドライバビリティの向上とを両立することができる。【選択図】図7
