Zusammenfassung:	To provide a control method of a rear wheel steering system for preventing a sudden change in a rear wheel steering control amount when an error occurs in a wheel speed sensor.SOLUTION: The control method of a rear wheel steering system comprises: detecting an error in wheel speed sensors on the basis of output values of the wheel speed sensors; when an error is detected in a wheel speed sensor, estimating a vehicle speed by using the output values of remaining normal wheel speed sensors excluding the output value of the abnormal wheel speed sensor where the error is detected; and steering and controlling rear wheels on the basis of the estimated vehicle speed.SELECTED DRAWING: Figure 2a 【課題】ホイールスピードセンサーのエラー発生の際に後輪操舵制御量の急激な変化を防止する後輪操舵システムの制御方法を提供する。【解決手段】本発明では、ホイールスピードセンサーの出力値に基づいてホイールスピードセンサーのエラーを検出し、前記ホイールスピードセンサーのエラーを検出した場合、エラーが検出された非正常ホイールスピードセンサーの出力値を除き、残りの正常ホイールスピードセンサーの出力値を用いて車速を推定し、前記推定された車速に基づいて後輪を操舵制御することを特徴とする、後輪操舵システムの制御方法を提供する。【選択図】図２ａ
