<p><P>PROBLEM TO BE SOLVED: To improve a shift feeling regardless of a gear stage to be changed. <P>SOLUTION: When a change of a gear stage is instructed in a state of applying torque to an input shaft of an automatic transmission from an engine, a torque phase is executed by applying a torque phase execution pressure to a clutch to be turned on and standing by, and a target torque-down quantityΔTe is set in such a tendency that the more an upshift stage Sn is a reduction side upshift stage, the larger the engine torque-down quantity becomes. In a state of standing by at the torque phase execution pressure Ptor, an inertia phase is started by the torque-down of the engine based on the target torque-down quantityΔTe to change the gear stage. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
