Claims (4)
- 댐퍼의 감쇄력를 조절을 통해 선회하는 차량의 자세를 제어하는 방법에 있어서,주행중인 차량의 횡가속도 신호를 연속적으로 수신하고;수신된 상기 횡가속도 신호를 미분하여 횡가속도 미분신호를 얻고;상기 횡가속도 신호 및 횡가속도 미분신호의 변화추이에 따라, 차량의 선회 구간을 선회 진입구간, 선회 진행구간, 그리고, 선회 출구구간으로 인식하고;인식되는 각 구간 별로 댐퍼의 감쇄력을 달리하여, 선회되는 차량의 자세를 각 구간별로 제어하는 것을;포함하는 것을 특징으로 하는 선회 차량의 자세 제어방법.
- 청구항 1에 있어서, 상기 각 구간에서, 상기 차량의 자세 제어는 전, 후륜 댐퍼의 감쇄력을 배분함으로써 이루어지는 것을 특징으로 하는 선회 차량의 자세 제어방법.
- 청구항 1 또는 청구항 2에 있어서,상기 선회 진입구간에서는 전륜 측으로의 감쇄력 배분율을 후륜 측에 비해 작게 하여 차량의 자세를 오버스티어(over steer)화하고, 상기 선회 출구구간에서는 전륜 측으로의 감쇄력 배분율을 후륜 측에 비해 크게 하여 차량의 자세를 언더 스티어(under steer)화 하는 것을 특징으로 하는 선회 차량의 자세 제어방법.
- 청구항 3에 있어서,상기 선회 진행구간에서의 전, 후륜 감쇄력 배분율은 선회 진입구간과 선회 출구구간 사이의 값으로 결정되는 것을 특징으로 하는 선회 차량의 자세 제어방법.
