Abstract

본 발명은 자동변속기를 장착한 차량에 있어서, 급가속시에 안정적인 킥다운에 의한 시프트다운을 가능하게 하기 위해 액셀페달을 70% 이상 밟을 때, 즉 드로틀밸브의 개도값이 킥다운에 시프트단운이 되는 값에 도달해도 시프다운을 소저시간 금지시키고 가속도(α)가 소정값에 도달한 경우에 시프트다운 이행하게 함으로써 운전자의 실수등으로 순간적으로 액셀을 밟을 때에는 시프트다운이 일어나지 않기 때문에 주행의 안정성이 확보되고, 불필요한 시프트다운에 의한 연료낭비가 없어지게 되어 상품성이 향상하게 된다.According to the present invention, in a vehicle equipped with an automatic transmission, when the accelerator pedal is pressed by 70% or more, that is, the opening value of the throttle valve is shifted to the kickdown in order to enable a shift-down by a stable kickdown during rapid acceleration. Even if the value reaches the desired value, the shift down is prohibited and the shift down is performed when the acceleration α reaches a predetermined value. As a result, fuel waste due to unnecessary shift-down is eliminated, thereby improving the merchandise.

Claims (1)

자동변속기가 장착된 차량의 자동변속기를 제어하는 자동변속기 제어부에 설치되어 킥다운을 판단하는 방법에 있어서, 엔진이 가동상태인지를 판단하는 단계(S2)와, 이 엔진이 가동하지 않으면 종료하는 단계(S10), 상기 엔진이 가동상태이면 변속맵에 따라 시프트다운을 결정하는 단계(S3), 이 단계에 의해 스프트다운이 적절한 지를 판정하여 적절하지 않음이 판정되면 다시 단계(S2)로 귀환하는 단계(S4), 이 단계(S4)에서 적절하면 @ t = 0으로 초기화 하는 단계(S5), @ t 값을 입력하는 단계(S6), 가속도(α)를 계산하는 단계(S7), 가속상태에 따라 시프트다운이 적절한 지를 판단해서 적절하지 않으면 다시 단계(S2)로 귀환하는 단계(S8) 및, 이 단계가 적절하명 시프트다운을 실행하는 단계(S9)를 포함하는 것을 특징으로 하는 변속제어방법A method of determining a kickdown provided in an automatic transmission control unit for controlling an automatic transmission of a vehicle equipped with an automatic transmission, the method comprising: determining whether the engine is in operation (S2); (S10), if the engine is in an operating state, determining a shiftdown according to the shift map (S3); determining whether the shiftdown is appropriate by this step and returning to step S2 again when it is determined that it is not appropriate. Step S4, in this step S4, if appropriate, initializing @ t = 0 (S5), entering a value of @ t (S6), calculating an acceleration α (S7), acceleration state According to the present invention, it is determined whether the shiftdown is appropriate, and if it is not appropriate, returning to step S2 (S8), and the shift control method comprising the step (S9) of executing the appropriately named shiftdown. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
