Patent ID: 7563195

Claim:
A speed change control device for an automatic transmission for a vehicle which speed changes and outputs the rotation output transmitted from a power source and, in an inertia phase of upshift speed changing, performs torque down control by reducing the output torque of the power source by a predetermined amount comprising: an inertia phase final period decision unit which decides whether or not the final period of the inertia phase is currently occurring; a return control unit which, if it has been decided by the inertia phase final period decision unit that the inertia phase is in its final period, performs return control by gradually decreasing the amount of decrease of output torque by the torque down control; a speed change progression decision unit which, during the return control, decides whether or not the speed change is progressing; and a resumption control unit which resumes the torque down control, if it has been decided by the speed change progression unit that the speed change is not progressing.
