Abstract
Description
Claims (2)
- 차량이 경사로에서 주정차 및 출발할 때 ECU가 엔진의 토르크만을 제어하여 차량을 경사로에서 주정차시키고, 출발 시 엔진과 변속기를 제어하여 후방 밀림없이 출발이 이루어지도록 하는 것을 특징으로 하는 경사로 출발 제어 방법.
- 가속도 센서의 신호값에 따라 ECU가 현재 차량이 경사로에 정차해있는지의 여부를 판단하는 단계와,차량이 경사로에 주정차한 상태에서 운전자가 작동스위치를 온시키게 되면 ECU는 가속도센서의 신호값을 통해 현재 차량이 주정차하고 있는 경사로의 경사도를 연산하는 단계와,상기한 경사도 연산 후 경사도에 따라 차량의 제동에 필요한 제동토르크를 연산하는 단계와,상기한 제동토르크 연산 후 현재의 엔진 토르크 및 변속기의 기어단수를 체크하여 차량이 경사로에서 정지할 정도로 엔진 토르크를 조절하는 단계와,엔진 토르크의 조절 후 운전자가 출발하려고 악셀러레이터 페달을 밟아 엔진 토르크가 일정 이상 상승하거나 악셀러레이터 페달 스위치가 온되면 ECU가 엔진과 변속기를 제어하여 차량이 후방 밀림없이 출발하도록 하는 단계로 구성함을 특징으로 하는 경사로 출발 제어 방법.
