In a torque control method of a drive system of an electric vehicle, in which torque is generated while evading a backlash band to prevent occurrence of backlash in the drive system, a front wheel torque command is determined as a value of equal to or less than a maximum front wheel torque threshold set to a negative (−) torque value, a rear wheel torque command is determined as a value of equal to or greater than a minimum rear wheel torque threshold set to a positive (+) torque value, and when an absolute value of the maximum front wheel torque threshold, and the minimum rear wheel torque threshold are referred to as offset torques, the offset torques are values varied depending on drive system state information.
