Abstract

자동차의 주행 속도가 크거나 또는 가속중인 경우에 자동차의 주 브레이크의 작동 불능시 비상 제동 장치로서 주차 브레이크를 작동시킬 수 있도록 변속기의 기어를 1단으로 강제 변환시키기 위하여 본 고안은 자동차의 주행 차속(Ni)과 예상 차속(Xi)을 비교하는 단계와, 상기 주행 차속(Ni)이 상기 예상 차속(Xi)보다 크면 아이들 스위치의 접점 상태를 판별하는 단계와, 상기 아이들 스위치의 접점 상태가 오프 상태이면 브레이크 스위치의 접점 상태를 판별하는 단계와, 장기 브레이크 스위치의 접점 상태가 온 상태일 때 자동차의 차속(N)을 검출하는 단계와, 상기 검출된 차속(N)을 검출하는 단계와, 상기 검출된 차속(N)과 상기 주행 차속(Ni)을 비교하여 산출된 차이값(Δ N)과 소정값(C)을 비교하는 단계와, 상기 차기값(Δ N)이 상기 소정값(C)보다 작으면 브레이크 페달의 작동에 의한 압력 센서값을 검출하는 단계와, 상기 검출된 압력 센서값을 설정값(D)을 비교하는 단계와, 상기 압력 센서값이 상기 설정값보다 작으면 기어 변속시키는 단계와, 상기 기어 변속에 의한 자동차의 주행 속도(Nf)와 예상 차속(Xf)을 비교하여서 상기 주행 차속(Nf)이 상기 예상 차속(Xf)보다 크면 자동차의 차속을 검출시키고 상기 주행 차속(Nf)이 상기 예상 차속(Xf)보다 작으면 이를 무시하는 단계로 이루어져 있는 자동차 제동 시스템을 제공한다.The present invention is designed to coerce the gear of the transmission to the first stage so that the parking brake can be operated as an emergency braking device when the main brake of the vehicle is inoperable when the driving speed of the vehicle is large or accelerated. Comparing Ni) with the expected vehicle speed Xi; determining the contact state of the idle switch when the driving vehicle speed Ni is greater than the expected vehicle speed Xi; and when the contact state of the idle switch is OFF. Determining the contact state of the brake switch, detecting the vehicle speed N of the vehicle when the contact state of the long-term brake switch is on, detecting the detected vehicle speed N, and detecting the detected Comparing a difference value ΔN and a predetermined value C calculated by comparing a vehicle speed N with the traveling vehicle speed Ni, and wherein the kick value ΔN is smaller than the predetermined value C. If Detecting a pressure sensor value by the operation of the electric pedal, comparing the detected pressure sensor value with a setting value D, shifting the gear when the pressure sensor value is smaller than the setting value, By comparing the traveling speed Nf of the vehicle by the gear shift and the expected vehicle speed Xf, if the traveling vehicle speed Nf is greater than the expected vehicle speed Xf, the vehicle speed of the vehicle is detected and the traveling vehicle speed Nf is If less than the expected vehicle speed (Xf) provides a vehicle braking system consisting of ignoring this.
