Zusammenfassung:	A method for controlling an electric vehicle driven by a plurality of electric motors including a first electric motor, in which a lubricant, which is used for lubricating the electric motors and power transmission systems therefor, is used for cooling the electric motors is provided. The method includes setting torque distributions for the plurality of electric motors on the basis of a driving force required by the electric vehicle controlling the drive of the plurality of electric motors on the basis of the set torque distributions and circulating intermittently the lubricant used for cooling the first electric motor when the torque distribution set for the first electric motor is smaller than a predetermined value which is regarded as a reference value.
