1. A steering control method for rear-wheel steering, the method comprising:

  • a calculation step in which a controller receives a vehicle speed and a front-wheel turning angle and calculates a rear-wheel same/inverse-phase control amount;

    an estimation step in which the controller estimates tire slip angles on the basis of factors showing a driving state of a vehicle when the vehicle is driven such that the rear wheels are controlled with the same phase;

    a compensation step in which the controller calculates a final rear-wheel turn control value by reflecting a control weight proportioned to the tire slip angle estimation value to the rear-wheel same-phase control amount; and

    a rear-wheel control step in which the controller turns the rear wheels by controlling a rear-wheel turn actuator on the basis of the final rear-wheel turn control value.
