Abstract

브레이크액의 변화를 감지하여 그에 해당하는 전기적인 신호를 출력하는 브레이크액 감지부와 ; 전원이 인가된 다음 상기 브레이크액 감지부에서 출력되는 신호를 입력으로 하여 급제동 상태를 판단하여, 급제동이 걸린 경우에는 급제동시에 해당하는 변속단을 설정하여 그에 따른 변속신호를 출력하는 제어부와 ; 상기 변속신호를 입력으로 하여 그에 따른 변속단을 설정하여 유압의 흐름을 제어하여 기어비를 낮추는 유압조절부로 이루어지는 자동변속 차량의 엔진 브레이크 장치는, 브레이크액이 흐르는 속도를 감지하여 브레이크액 속도가 설정이상으로 빨라져 급제동이 이루어진 경우에는, 그에 따른 변속패턴을 재선택하여 기어비를 낮추므로써 엔진 브레이크 효과를 얻어 미연에 사고를 방지할 수 있으며, 그 제어 방법을 제공할 수 있다.A brake fluid detection unit for detecting a change in brake fluid and outputting an electrical signal corresponding thereto; A control unit for determining a rapid braking state by inputting a signal output from the brake fluid detecting unit after power is applied, and setting a shift stage corresponding to a sudden braking when the braking is applied; The engine brake device of an automatic transmission vehicle comprising a hydraulic control unit for reducing the gear ratio by controlling the flow of hydraulic pressure by setting the shift stage according to the shift signal as an input, and the brake fluid speed is higher than the set value by detecting the speed at which the brake fluid flows. When the rapid braking is performed, re-selecting the shift pattern and lowering the gear ratio results in an engine brake effect, thereby preventing accidents and providing a control method.
