The present invention relates to technique for improving stability of a vehicle by increasing understeer and oversteer control effects by feedback control when understeer or oversteer occurs and, more specifically, provides a method for controlling rear wheel steering of a vehicle, which can improve stability of a vehicle by increasing understeer and oversteer control effects by feedback control by suppressing an offsetting phenomenon of feedforward rear wheel steering amount and a feedback rear wheel steering amount when understeer or oversteer occurs in the vehicle applied with a rear wheel steering system in which feedforward and feedback control are simultaneously operated.
본 발명은 언더스티어 또는 오버스티어 발생시, 피드백 제어에 의한 언더스티어 및 오버스티어 제어효과를 증대시켜 차량의 안정성을 향상시키는 기술에 관한 것으로, 본 발명에서는 피드포워드와 피드백제어가 같이 작동하는 후륜 조향시스템이 적용된 차량에서 언더스티어나 오버스티어가 발생하는 경우, 피드포워드 후륜조향량과 피드백 후륜조향량의 상쇄현상을 억제함으로써, 피드백 제어에 의한 언더스티어 및 오버스티어 제어효과를 증대시켜 차량의 안정성을 향상시키는 것을 특징으로 하는 차량용 후륜 조향 제어방법이 소개된다.
