Claims (4)
- 조타 핸들의 조타 조작을 어시스트하기 위한 액츄에이터를 구비한 차량의 조타 장치에 있어서,조타 핸들로부터 입력되는 조타 토크를 검출하는 조타 토크 센서와,조타 핸들의 복귀 조타시의 조타 조작을 어시스트하기 위한 복귀 토크를, 상기 조타 토크 센서에 의해 검출된 조타 토크가 커짐에 따라 작아지도록 결정하는 복귀 토크 결정 수단과,상기 복귀 토크 결정 수단에 의해 결정된 복귀 토크에 따라 상기 액츄에이터를 구동 제어하는 구동 제어 수단을 구비하는 것을 특징으로 하는 차량의 조타 장치.
- 제 1 항에 있어서,상기 조타 장치는 조타 핸들의 조타각을 검출하는 조타각 검출 센서를 구비하고,상기 복귀 토크 결정 수단은, 상기 복귀 토크를, 상기 조타각 센서에 의해 검출된 조타각이 커짐에 따라 커지도록 결정하는 것을 특징으로 하는 차량의 조타 장치.
- 제 2 항에 있어서,상기 복귀 토크 결정 수단은, 상기 복귀 토크의 기준이 되는 토크인 기준 복귀 토크를 상기 조타각 센서에 의해 검출된 조타각이 커짐에 따라 커지도록 결정하는 기준 복귀 토크 결정 수단과, 상기 기준 복귀 토크에 대한 게인을 상기 조타 토크 센서에 의해 검출된 조타 토크가 커짐에 따라 작아지도록 결정하는 복귀 토크 게인 결정 수단을 구비하고, 상기 기준 복귀 토크 결정 수단에 의해 결정된 토크와 상기 복귀 토크 게인 결정 수단에 의해 결정된 게인에 기초하여 상기 복귀 토크를 결정하는 것을 특징으로 하는 차량의 조타 장치.
- 제 1 항 내지 제 3 항 중 어느 한 항에 있어서,조타 핸들의 회전 조타시의 조타 조작을 어시스트하기 위한 회전 토크를, 상기 조타 토크 센서에 의해 검출된 조타 토크가 커짐에 따라 커지도록 결정하는 회전 토크 결정 수단을 추가로 구비하고,상기 구동 제어 수단은, 상기 회전 토크 결정 수단에 의해 결정된 회전 토크와 상기 복귀 토크 결정 수단에 의해 결정된 복귀 토크에 따라 상기 액츄에이터를 구동 제어하는 것을 특징으로 하는 차량의 조타 장치.
