A vehicle gear-shifting control apparatus is equipped with an engine, a motor, an automatic transmission, a friction brake system, and a controller which executes regeneration control and gear-shifting control during deceleration of the vehicle with a braking force to front and rear wheels. The controller increases an input torque of an input shaft according to a downshift so that an accompanying acceleration fluctuation equals a target acceleration fluctuation. When the controller determines an oversteered state during the regeneration control and during a downshift, the controller increases the input torque so that a regenerative braking torque decreases while maintaining a regeneration operation of the motor and, at the same time, the controller causes the automatic transmission to perform the downshift in a state where an amount of increase of the input torque in accordance with the downshift has been increased compared to during a non-determination of the oversteered state.
