Abstract
본 발명은 차량자동변속기의 변속레버변화에 따른 변속충격방지방법에 관한 것으로, 자동변속기(1)가 엔진(1′)과 각종 구성부들을 제어하는 TCU(8)및 ECU(9)에 의해 제어 되도록 전기적으로 서로 연결되어 폐회로를 구성함과 더불어, 상기 TCU(8)에 의해 변속레버변환부(5)의 작동변화에 따른 엔진의 점화시기 점화지연범위(R)로 판단 되어져, 엔진의 토오크를 감소시켜 주므로 인해 자동변속기의 변속시 발생되는 기어치합에 따른 변속충격을 최소화 시킬 수 있게 됨은 물론, 자동변속기의 내구성과 상품성도 향상될 수 있도록 된 것이다.The present invention relates to a shift shock prevention method in accordance with a shift lever change of a vehicular automatic transmission and more particularly to an automatic transmission 1 in which an automatic transmission 1 is controlled by a TCU 8 and an ECU 9 which control an engine 1 ' And the ignition timing ignition delay range R of the engine is determined by the TCU 8 as a result of the change in the operation of the shift lever change portion 5 so that the torque of the engine The shift shock due to gear engagement occurring in shifting of the automatic transmission can be minimized, as well as the durability and merchantability of the automatic transmission can be improved.
