ABSTRACT:
In a transmission during a shifting process while torque is transferred from a power-outputting clutch, which is initially in the adhered state, to a power-receiving clutch, which is initially open, the power-receiving clutch increases torque capacity in a slip region, and the power-outputting clutch decreases torque capacity during an initial phase of the transfer of torque while its torque capacity is greater than necessary to maintain its adhered state. In the final state of the transfer of torque, the power-receiving clutch transmits the entire drive torque.
