철도차량용 전기기계식 제동ECU의 입출력 인터페이스 분석

초록

Air brake systems have widely used in railroad vehicles, because of them having a fail-safe function that engages brake when brake pipe is broken. But, these brake systems have some limitations such as heavy equipment weight, temperature dependency, long reaction time. To overcome these limitations, electromechanical brake systems for railroads are being developed in, at least, Europe and Korea. The EMB system should have compatibility with existing vehicles and investigated in whole brake system scope. In this paper, we analyzed interfaces between brake ECU and its peripherals to develop an EMB system that is compatible to existing railroad vehicles.
