The present invention relates to a hardware-in-the-loop simulation (HILS) system for braking a railway vehicle. The HILS system for braking the railway vehicle according to the present invention includes a user terminal receiving values related to braking conditions of the railway vehicle through a user interface and monitoring the results of simulation, an electric control unit (ECU), a braking operation unit (BOU), wheelsets, a brake caliper, and a slip-prevention valve. Additionally, the HILS system for braking the railway vehicle includes a pneumatic control device generating air pressure according to the braking conditions received from the user terminal and transmitting a braking force to the wheelsets; a load cell installed in an axle or a disc and measuring the braking force based on the air pressure; and a modeling unit applying the braking force to a mathematic model for vehicle operation simulation and a virtual railway vehicle and simulation dynamic characteristics of the operation and the braking of the railway vehicle based on a real time basis. The present invention simulates conditions corresponding to the dynamic characteristics of the railway vehicle and electric braking conditions of on a real time basis and provides a pneumatic braking system including the ECU with actual hardware, thereby providing test conditions identical to the actual railway vehicle by joining all components related to the braking operation with the HILS system for braking the railway vehicle.

    본 발명은 철도차량 제동 HILS 시스템에 관한 것이다. 본 발명에 따른 철도차량 제동 HILS 시스템은, 사용자 인터페이스를 통하여 철도차량의 제동 조건에 관한 값들을 입력받으며, 시뮬레이션 결과를 모니터링하기 위한 사용자 단말기, 전자제어장치(ECU), 제동작용장치(BOU), 윤축, 브레이크 캘리퍼 및 활주방지밸브를 포함하며, 상기 사용자 단말기로부터 입력받은 제동조건에 따라 공기압을 생성하여 상기 윤축에 제동력을 전달하는 공압제동장치, 차륜 또는 디스크에 설치되며, 상기 공기압으로부터 제동력을 측정하는 로드셀, 그리고 차량 주행 시뮬레이션을 위한 수학적 모델과 가상 철도차량에 상기 제동력을 적용하여 상기 가상 철도차량의 주행 및 제동 동특성을 실시간 시뮬레이션하는 모델링부를 포함한다. 이와 같이 본 발명에 따르면, 철도차량 제동 HILS 시스템에서 차량 동특성에 해당하는 부분과 전기제동 부분을 실시간 시뮬레이션으로 구현하고, ECU를 포함한 공압제동시스템을 실제 하드웨어로 구현함으로써, 제동과 관련 모든 부품을 철도차량 제동 HILS 시스템과 결합하여 실제 철도차량과 동일한 시험 환경을 제공할 수 있다.
