Gear shift control device and control method for a vehicle

The invention relates to a control device and a control method for a vehicle, wherein at the time of a change-speed, by correcting the torque reducing portion of an output shaft (20) during the change-speed, the revolution number of an input shaft (8) is controlled on the basis of the corrected torque reduction correcting value. Also, the torque of said input shaft (8) is adjusted at the end of the change-speed on the basis of said torque correcting value.
