- 유압식 동력 조향 장치의 모터에 의해 구동되는 펌프의 회전 속도를 조향 속도에 따라 조정하는 방법으로서,유압 유체를 조향 밸브에 공급하는 펌프를 제공하는 단계와;상기 펌프를 구동하는 모터를 제공하는 단계와;조향 속도를 감지하는 단계와;감지된 조향 속도에 따라, 상기 펌프에 의해 상기 조향 밸브에 공급되는 유압 유체의 초기 체적유량을 결정하는 단계와;임의적으로 이용할 수 있는 예비 유량을 제공하는 조정 체적유량까지 상기 초기 체적유량을 증대시키는 보정치(B)를 결정하는 단계; 그리고상기 조향 밸브에 상기 조정 체적유량의 유압 유체를 공급하는 속도로 상기 펌프가 모터에 의해 구동되도록, 상기 조정 체적유량에 기초하여 모터의 회전 속도를 설정하는 단계를 포함하며, 상기 보정치는 상기 조정 체적유량이 펌프의 최대 유압 출력을 초과하지 않는 범위 내에서 변동되고, 동력 조향 장치 전체의 효율을 고려하여 결정되는 것인 펌프의 회전 속도를 조향 속도에 따라 조정하는 방법.
- 제1항에 있어서, 상기 조향 속도는 측정된 조향 회전 속도에 기초하여 확정되는 것을 특징으로 하는 펌프의 회전 속도를 조향 속도에 따라 조정하는 방법.
- 제1항 또는 제2항에 있어서, 상기 초기 유압 체적유량을 측정하는 것을 특징으로 하는 펌프의 회전 속도를 조향 속도에 따라 조정하는 방법.
- 제1항 또는 제2항에 있어서, 상기 보정치(B)는 상기 초기 체적유량에 따라 결정되는 것을 특징으로 하는 펌프의 회전 속도를 조향 속도에 따라 조정하는 방법.
- 제1항 또는 제2항에 있어서, 상기 조향 속도와 보정치(B)는 컴퓨터에 의해 결정되는 것을 특징으로 하는 펌프의 회전 속도를 조향 속도에 따라 조정하는 방법.
- 제1항 또는 제2항에 있어서, 상기 보정치를 결정하고, 이를 조향 장치마다 저장하는 것을 특징으로 하는 펌프의 회전 속도를 조향 속도에 따라 조정하는 방법.
- 제1항 또는 제2항에 있어서, 상기 회전 속도는 펄스 폭 변조 방법에 의해 조절되는 것을 특징으로 하는 펌프의 회전 속도를 조향 속도에 따라 조정하는 방법.
