The present invention relates to a method for preventing ISG restart shock and moving back on uphill and downhill paths in an automatic transmission and, more specifically, to a method for preventing ISG restart shock and moving back on uphill and downhill paths in an automatic transmission, which uses hydraulic pressure maintained by the operation of an auxiliary oil pump when an engine is stopped according to an ISG entry condition so that a planetary gear element of an automatic transmission is constrained to prevent movement of an output side of the automatic transmission and a turbine of a torque converter, and in case of engine restart under ISG release condition, releases the constraint of the planetary gear element according to fuzzy logic by reflecting the amount the accelerator pedal is depressed, the amount of change in a brake pedal and traveling environment of uphill and downhill paths immediately after entering a restart condition reflecting the acceleration intention of a driver.

    본 발명은 자동변속기에서 ISG 재시동충격 및 등강판로 밀림 방지 방법에 관한 것으로서, 보다 상세하게는 ISG 진입조건에 따라 엔진정지 시 보조 오일 펌프 작동으로 유지되는 유압을 이용하여 자동변속기의 유성기어 요소를 구속하여 토크컨버터의 터빈 및 자동변속기 출력측의 움직임을 방지하고, ISG 해제조건에 따른 엔진재시동의 경우, 운전자의 가속의지를 반영하는 재시동 조건 진입 직후 가속페달의 양과 브레이크 페달의 변화량, 등강판 등의 주행환경을 반영하여 퍼지로직에 따라 유성기어요소의 구속을 해제하는 자동변속기에서 ISG 재시동충격 및 등강판로 밀림 방지 방법을 제공하는 자동변속기에서 ISG 재시동충격 및 등강판로 밀림 방지 방법에 관한 것이다.
