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 a regeneration control of imparting a regenerative braking torque to rear wheels by causing the motor to perform a regeneration operation and a gear-shifting control of changing a shift stage of the automatic transmission by outputting a gear-shifting signal in accordance with the rotation speed of an input shaft. The controller starts the gear-shifting control, triggered by the rotation speed decreasing to a predetermined downshift point during a downshift of the shift stage, and during deceleration of the vehicle when a coefficient of friction of a road surface is lower than a predetermined threshold in the regeneration control, the controller sets the downshift point lower than when the coefficient of friction is equal to or higher than the threshold.
