A drivetrain from a drive source to drive wheel is provided with a motor-generator for implementing regeneration during deceleration and an automatic transmission having an engaging clutch as a shifting element. The electric vehicle has a gear shifting controller that is programmed to assess whether to grant gear shifting permission based on whether a deceleration grade difference occurring as a result of a reengagement gear shifting is less than a prescribed acceptable deceleration fluctuation when a reengagement gear shift request involving disengaging or engaging the meshing clutch is made during deceleration or regeneration. Shifting is initiated according to the gear-shift request if a decision to grant gear shifting permission is made.
