VEHICLE GEAR-SHIFTING CONTROL APPARATUS, AND VEHICLE

A vehicle gear-shifting control apparatus is equipped with an engine, a motor, an automatic transmission, a friction brake system, and a controller. The controller increases an input torque of an input shaft according to a shift-down so that an acceleration fluctuation of the vehicle which accompanies the shift-down equals a target acceleration fluctuation, and when the controller determines an oversteered state during regeneration control and during a shift-down, the controller increases the input torque of the input shaft so that a regenerative braking torque decreases while maintaining a regeneration operation of the motor and the controller causes the automatic transmission to perform the shift-down in a state where an amount of increase of the input torque of the input shaft in accordance with the shift-down has been increased as compared to during a non-determination of an oversteered state.
