<P>PROBLEM TO BE SOLVED: To provide a method for controlling a motor of an electric vehicle, in which basic control stability is maintained even when a voltage of a battery fluctuates, and control reliability and accuracy are improved. <P>SOLUTION: The method for controlling the motor of the electric vehicle comprises a step of receiving an output voltage of a battery providing driving power to the motor, and speed and torque of the motor; a step of generating a magnetic flux based current control map using the output voltage of the battery, the speed and the torque of the motor; and a step of generating a current control command using the magnetic flux based current control map. The method further comprises a step of generating a driving point ratio (1/λ<SB POS="POST">max</SB>) from the output voltage (V<SB POS="POST">dc</SB>) of the battery and the speed (ω<SB POS="POST">r</SB>) of the motor, and generating a torque control command by using the speed and torque of the motor; and a step of generating a voltage control command from the current control command. <P>COPYRIGHT: (C)2013,JPO&INPIT |
