The present invention relates to a technique for stably controlling rear wheel steering of a vehicle by diagnosing an error or an abnormality in a wheel speed. According to the present invention, disclosed is the rear wheel steering control method which statistically analyzes a wheel speed to detect errors in the wheel speed, thereby determining not only whether the wheel speed is abnormal but also whether an error in the wheel speed occurs. Moreover, a rear wheel is steered by estimating a vehicle speed based on a normal wheel speed by excluding the wheel speed where the error occurred when the error or abnormality of the wheel speed occurs, thereby stably controlling rear wheel steering.

    본 발명은 휠속도의 오류 및 이상 여부를 진단하여 차량의 후륜 조향을 안정적으로 제어하는 기술에 관한 것으로, 본 발명에서는, 휠속도를 통계적으로 분석하여 휠속도의 오류를 검출함으로써, 휠속도의 이상 여부 뿐 아니라 오류 여부까지도 판단하고, 더불어 휠속도의 오류 및 이상 발생시 오류가 발생한 휠속도를 배제하고 정상적인 휠속도를 기반으로 차속을 추정하여 후륜을 조향함으로써, 후륜 조향 제어가 안정적으로 이루어질 수 있는 후륜 조향 제어방법이 소개된다.
