Abstract

본 발명은 자동 변속기를 사용하여 자동차에서 변속단 선택의 제어방법에 관한 것으로, 운행되는 자동차에서 변속되고자 요구하는 기어단의 포지션을 검출한 후 각 포지션 기어단에 설정된 엔진의 RPM에 따라 기어의 변속이 이루어지도록 한 A/T장착 자동차의 변속단 선택 방법에 관한 것이다. 본 발명은 운행되는 자동차의 기어 변속 요구의 값에 따라 현재 선택되어 운행되는 기어의 변속단을 검출한 후 변속이 가능한지의 여부를 판단하고 엔진의 RPM이 요구되는 변속단에 설정된 RPM이내에 포함되는지의 여부에 따라 변속을 진행흐므로 변속단의 선택이 엔진의 출력에 무리를 주지 않아 엔진의 과부하 발생이 방지되고, 파워 트레인의 무리한 출력동작이 배제되어 내구성 및 운행의 신뢰성이 향상된다.The present invention relates to a control method of shift stage selection in an automobile using an automatic transmission, and after detecting a position of a gear stage required to be shifted in a driving vehicle, the gear is shifted according to the RPM of the engine set in each position gear stage. The present invention relates to a shift stage selection method of an A / T-equipped vehicle. According to the present invention, after detecting a gear shift stage of a currently selected and driven gear according to a value of a gear shift request of a driving vehicle, it is determined whether the shift is possible and whether the RPM of the engine is included within the RPM set in the required shift stage. Since the shifting is carried out depending on whether the shift stage selection does not affect the output of the engine, the overload of the engine is prevented, and the excessive output operation of the power train is excluded, thereby improving durability and reliability of operation.
