초록

건설기계 산업에서 배기 및 연비 규제를 만족하기 위하여 엔진 시스템이 점차 전자제어화 되고 있으며, 이를 제어하기 위한 EMS(Engine Management System)의 복잡도 또한 증가하고 있다. 본 연구에서는 EMS function 개발 시, 비용 및 개발기간의 단축을 위한 HiLS(Hardware in the Loop Simulation) 시스템을 개발하였다. HiLS 에 내장된 엔진 모델은 크게 Air, Fuel, Torque 및 동력계 모델로 구성되어있고 실시간 엔진 모사를 위하여 Mean value modeling 방법을 적용하였다. 이 연구를 통하여 개발한 HiLS 시스템은 EGR(Exhaust Gas Recirculation) 시스템과 Turbocharger 가 장착된 건설기계용 디젤엔진을 이용하여 정확성을 검증하였고, 테스트 결과 실 엔진 대비 90% 이상의 정확도를 얻었다.

Recently, the portion of electronic control in an engine system has been increasing with the aim of meeting the requirements of emissions and fuel efficiency of the engine system in the construction machinery industry. Correspondingly, the complexity of the engine management system (EMS) has increased. This study developed an engine HiLS system for reducing the cost and time required for function development for the EMS. The engine model for HiLS is composed of air, fuel, torque, and dynamometer models. Further, the mean value method is applied to the developed HiLS engine model. This model is validated by its application to a heavy-duty diesel engine equipped with an exhaust gas recirculation system and a turbocharger. Test results demonstrate that the model has accuracy greater than 90 and also verify the feasibility of the virtual calibration process.
