The present invention involves a system and method of controlling a steering wheel for simulated steering feel on a steering wheel of a vehicle with front road wheels in a steer-by-wire system. The method includes sensing actual torsion on the steering wheel, comparing the actual torsion to a threshold torque value, sensing actual angular velocity of the steering wheel, and comparing the actual angular velocity to a threshold angular velocity. The method further includes generating a simulated steering feel torque on the steering wheel, if the actual torsion is greater than the threshold torque value and the actual angular velocity is less than the threshold angular velocity. The method further comprises returning the steering wheel to the center position at a specified angular velocity, if the actual torsion is less than the threshold torque value and the actual angular velocity is greater than the threshold angular velocity.
