Claim 0:
1. A road impact simulating apparatus of a steer-by-wire system, the apparatus comprising a controller configured to:
determine a wheel speed difference value between wheels, and determine a lateral acceleration difference value between an estimated lateral acceleration of a vehicle and a sensed lateral acceleration of the vehicle;
determine whether there is a road impact based on the wheel speed difference value between the wheels; and
determine a reaction force torque according to the road impact based on the lateral acceleration difference value if it is determined as the road impact,
wherein the controller is configured to, if a first wheel speed difference value between the left and right front wheels is greater than or equal to a first reference value, a second wheel speed difference value between the left and right rear wheels is less than or equal to a second reference value, and a third wheel speed difference value between the left front and rear wheels or a fourth wheel speed difference value between the right front and rear wheels is greater than or equal to a third reference value, determine that there is the road impact.
