In a torque control method for a drive system of an electric vehicle configured for generating torque by evading a backlash band to prevent occurrence of backlash in the drive system, torque control modes include a contra-directional distribution mode in an acceleration direction in which a front-wheel torque command is determined to be a maximum front-wheel torque threshold value set as a negative (−) torque value in a regenerative direction and a rear-wheel torque command is determined to be a positive (+) torque value in a driving direction and a contra-directional distribution mode in a regenerative direction in which the rear-wheel torque command is determined to be a minimum rear-wheel torque threshold value set as a positive (+) torque value in the driving direction and the front-wheel torque command is determined to be a negative (−) torque value in the regenerative direction thereof.
