The invention discloses a gear-shifting control method for an electric automobile. The gear-shifting control method comprises the following steps: S11, wherein when a request gear released by a motor controller is consistent with a target gear released by a drive control unit, an electrical generator is controlled to conduct a first torque unloading; S12, wherein when the unloading is completed, the drive control unit controls a motor power shaft synchronizer to disconnect, and when the electrical generator is at neutral position, the motor controller calculates the target shift revolving speed of the electric generator and controls the electrical generator to conduct the torque loading, and when the revolving speed reaches a preset motor speed range, the motor controller controls the electric generator to conduct a second torque unloading; S13, wherein when the unloading is completed, the drive control unit controls the motor power shaft synchronizer to initiate combination; S14, wherein the motor controller judges the current gear of the electric generator released by the drive control unit is the request gear and confirms successes of the electrical generator gear-shifting. By means of the gear-shifting control method for the electric automobile, evenness and comfort of the finished automobile can be improved. The invention further discloses a motor speed adjusting method of an electrical automobile.
