Abstract

스로틀 밸브의 개도량이 아이들 상태에 해당하는 개도량을 기준으로 하여, 기준값 이하인 부분인 3속에서 1속으로 다운 시프트되는 패턴과 1속에서 2속으로 업 시프트되는 패턴을 일정 정도만큼 고속 방향으로 후퇴시킨 상태로 변속 패턴을 설정하여, 주행 속도가 저속 상태이고 1속을 유지하고 있을 경우 가속 페달을 조작에 따라 스로틀 밸브 개도량의 수직 상승에 따른 불필요한 업 시프트 동작으로 제거할 수 있도록 하고, 감속시 고속 상태에서 3속에서 1속으로의 다운 시프트될 수 있도록 하여 재발진시 가속 성능을 향상시킬 수 있도록 하는 자동 변속기의 변속 패턴 제어 장치에 관한 것이다.On the basis of the opening amount corresponding to the idle state, the throttle valve is retracted in a high speed direction by a predetermined amount of the pattern shifted down from 3 speed to 1 speed and from 1 speed to 2 speed based on the opening amount corresponding to the idle state. When the speed is low and the speed is maintained at 1 speed, the accelerator pedal can be removed by unnecessary upshift operation due to the vertical rise of the throttle valve opening amount according to the operation. The present invention relates to a shift pattern control apparatus of an automatic transmission that can be downshifted from three speeds to one speeds in a high speed state to improve acceleration performance when re-starting.

Claims

On the basis of the opening amount corresponding to the idle state, the throttle valve is retracted in a high speed direction by a predetermined amount of the pattern shifted down from 3 speed to 1 speed and from 1 speed to 2 speed based on the opening amount corresponding to the idle state. When the speed is low and the speed is maintained at 1 speed, the speed change pattern can be set so that unnecessary upshift operation due to the vertical rise of the throttle valve opening amount can be eliminated according to the acceleration and closing operation. A shift pattern control device of an automatic transmission, which can be downshifted from three speeds to one speed in a high speed state to improve acceleration performance when re-starting.
