In one mode of a steer-by-wire system, a steer-by-wire control apparatus, and a steer-by-wire control method according to the present invention, when a vehicle is undergoing skid, a reaction force generation apparatus decreases or increases reaction force torque from basic reaction force torque calculated from a steering angle of a steering wheel, based on the steering angle, a vehicle speed of the vehicle, and motor torque of a turning motor, and outputs the calculated reaction force torque as skid reaction force torque. In this way, the driver can be appropriately notified of a vehicle skid state via the steering wheel.
