Abstract

가속 페달에 연동하는 작동상태가 가변되어 그에 해당하는 전기적인 신호를 출력한ㄴ 아이들 스위치와; 엔진 구동에 따라 회전하는 변속기의 입력측 터빈 회전수를 감지하여 엔진 회전수 감지 수단과; 가속 페달에 연동하는 스로틀 밸브의 개도량을 감지하여 그에 해당하는 전기적인 신호를 출력하는 스로틀 밸브 감지수단과; 변속기의 출력측 회전수인 차속을 감지하여 그에 해당하는 전기적인 신호를 출력하는 차속 감지수단과; 4속으로 주행하는 도중에 아이들 스위치가 작동되는 경우에, 감지되는 엔진 회전수가 3속시의 기어비를 곱산 변속기 출력축 회전수보다 일정값이상 큰 경우에만 3속으로의 다운 시프트 변속신호를 출력하는 변속제어 수단과; 상기 변속제어수단에서 출력되는 변속신호에 따라 해당하는 마찰요소를 작동시켜 변속동작을 수행하느 변속수단을 포함하여 이루어지는 아이들시의 다운 시프트 변속제어장치는 4속으로 주행하는 도중에 가속 페달에서 발을 떼어 아이들 스위치가 작동된 경우에, 현재 엔진 회전수가 3속시의 변속기 출력측 회전보다 큰 경우에만 3속으로의 다운 시프트 변속을 수행함으러써, 차량의 파워 온 상태에서 파워 오프 상태로의 변환에 따른 변속감 저하를 방지하고, 제어 로직을 간단화할 수 있다.An idle switch configured to vary an operating state linked to the accelerator pedal and output an electrical signal corresponding thereto; Engine speed sensing means for sensing an input turbine speed of a transmission rotating in accordance with engine driving; Throttle valve detecting means for detecting an opening amount of a throttle valve linked to an accelerator pedal and outputting an electrical signal corresponding thereto; Vehicle speed detecting means for detecting a vehicle speed which is an output speed of the transmission and outputting an electrical signal corresponding thereto; Shift control means for outputting a downshift shifting signal to three speeds only when the engine speed detected is greater than a predetermined value than the transmission output rotation speed by multiplying the gear ratio at three speeds when the idle switch is operated while driving at four speeds. and; The downshift shift control device in idle, which includes shifting means for shifting by operating a corresponding friction element according to the shifting signal output from the shifting control means, takes the foot off the accelerator pedal while driving at 4 speeds. When the idling switch is operated, the downshift shifting to the third speed is carried out only when the current engine speed is greater than the transmission output side rotation at the third speed, thereby reducing the shifting feeling due to the transition from the power-on state to the power-off state of the vehicle. , And the control logic can be simplified.
