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.
