A motor torque control device of a vehicle steering system includes: an imaginary steering torque determination unit to estimate an imaginary steering torque which is input to a steering gear of a vehicle when a steering wheel of the vehicle is rotated at a maximum steering angle; a subtraction torque determination unit to calculate a difference between the imaginary steering torque and an actual steering torque; a compensation torque determination unit to determine a compensation torque for compensating the actual steering torque based on the difference and a vehicle speed of the vehicle; and a motor torque determination unit to determine an output torque of an electromotor based on the compensation torque and a motor assist torque of the electromotor.
