Abstract
Description
Claims (1)
- 차량이 전륜각 감지신호와 차속신호를 입력으로 함과 더불어 차량의 무게중심에 설치되는 요레이트 센서(18)가 요레이트신호(γ)를 출력하게 되면 4륜 제어로직(14)이 요레이트신호(γ)를 신호원으로 하여 전륜조향각과 요레이트의 함수를 포함하는 전달함수()를 통해 얻어진 제어신호에 따라 후륜 액튜에이터(16)가 구동될 수 있도록 하는 요레이트를 이용한 4륜 조향시스템의 제어방법. 상기, δf는 전륜각이고, Cf는 전륜타이어강성이며, Cr는 후륜타이어강성이고, M은 차체중량이며, a는 무게중심에서 차의 암까지의 거리이고, b는 무게중심에서 차의 후미까지의 거리이며, u는 차속이고, γ는 요레이트이다.
