The present invention comprises the following steps of: determining a backlash vulnerable area when driving a vehicle; split controlling a front wheel motor and a rear wheel motor when an area of the vehicle is the backlash vulnerable area; selecting a driving motor and a regenerative motor among the front wheel motor and the rear wheel motor for the split control; and controlling the selected driving motor and the regenerative motor by zero torque. The present invention split controls driving and regenerating operation of the motor to prevent a backlash so as to enable rapid responsive control.
