Abstract

본 발명은 퍼지제어를 이용한 자동변속 차량의 엔진 브레이크 제어 시스템에 관한 것으로서, 트랜스 액슬 콘트롤 유니트(T.C.U)내의 컴퓨터에 프로그램된 변속패턴에 의해 이루어지기 때문에 주행도중 브레이크를 밟는 경우 엔진 브레이크가 걸리지 않고 불필요한 변속이 발생하여 브레이크 효과를 얻지 못하는 경향이 있으며 결과적으로 차량의 주행상태에 따라서는 운전자의 의지와 불일치한 변속이 발생질 수 있고 안전사고의 위험성을 내포하고 있는 종래의 문제점을 해결하고자 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine brake control system for an automatic transmission vehicle using fuzzy control, and is made by a shift pattern programmed in a computer in a transaxle control unit (TCU). There is a tendency that a shift does not occur and a brake effect is not obtained, and as a result, a shift inconsistent with the driver's will may occur depending on the driving state of the vehicle, and a conventional problem that includes a risk of a safety accident is to be solved.

이를 해결하기 위한 본 발명은 기존의 자동변속패턴에 의해 변속여부를 결정한 후 결정된 변속단으로 변속제어되기 전에 퍼지제어를 통한 엔진 브레이크 여부를 확인하여 퍼지제어 결과 전체규칙에 의한 출력값이 변수와 같거나 작으면 목표변속단 결정 파트로 넘어가고 출력값이 변수보다 크면 변속을 하지 않고 엔진 브레이크로 넘어감으로써 변속시기가 운전자의 의지에 부합하여 차량 주행을 보중하도록 한 것이다.The present invention to solve this problem is to determine whether the shift by the existing automatic shift pattern and then check whether the engine brake through the fuzzy control before the shift control to the determined shift stage, the output value according to the overall rule of the fuzzy control result is equal to the variable or If it is small, it shifts to the target shift stage decision part, and if the output value is larger than the variable, it shifts to the engine brake without shifting, so that the shift timing is in line with the driver's will to supplement the driving of the vehicle.
