Abstract:
1. A control apparatus which transmits torque from a power plant to first and second intermediate shafts respectively via first and second input clutches, transfers torque from the two intermediate shafts to an output shaft via transmission gears and shifting clutches that are respectively provided on the transmission gears, and transfers torque from a shifting position of the first intermediate shaft to a shifting position of the second intermediate shaft by a motor which is differentially connected between the intermediate shafts; wherein a torque transition is conducted along a torque transmission route of the second input clutch, the second intermediate shaft, the motor, the first intermediate shaft, and a gear position of the first intermediate shaft before shifting; when a shifting command is submitted while torque is transmitted from the power plant to the output shaft via the first intermediate shaft, the transmission gear of the first intermediate shaft, and the shifting clutch on the first intermediate shaft while the first input clutch is engaged and the second input clutch is disengaged, the control apparatus engages the second input clutch of the second intermediate shaft to form the torque transmission route of the power plant, connected to a first input shaft, the second intermediate shaft, a second input shaft connected to the motor, the transmission gear on the first intermediate shaft, and the shifting clutch on the first intermediate shaft, and then disengages the first input clutch, engages the shifting clutch of the transmission gear on the second intermediate shaft, and disengages the shifting clutch of the transmission gear on the first intermediate shaft; and the control apparatus outputs a torque equivalent to the torque of the power plant from the motor before disengaging the first input clutch.
