According to the embodiments of the present invention, the method to control an engine system comprises the steps of: detecting a control current value of an electronic proportional control pressure-reducing valve (EPPR) to control a regulator to adjust a discharge pressure of a discharged oil discharged from a variable capacity-type oil pressure pump driven by an engine, a revolution count of a driving axis to drive the oil pressure pump, and a swash plate of the oil pressure pump; estimating a load applied to the engine in a pump control leading and pump efficiency map of the oil pressure pump based on the discharge pressure, the revolution count, and the control current value; and controlling an opening of an exhaust gas recirculation device (EGR) valve and a throttle valve based on an estimated load applied to the engine and the revolution count.

    예시적인 실시예들에 따른 엔진 시스템 제어 방법은 엔진에 의해 구동되는 가변용량형 유압 펌프에서 토출되는 토출유의 토출 압력, 상기 유압 펌프를 구동하는 구동축의 회전수, 및 상기 유압 펌프의 사판을 조정하기 위한 레귤레이터를 제어하는 전자비례제어 감압밸브(EPPR)의 제어 전류값을 검출하는 단계, 상기 토출 압력, 상기 회전수 및 상기 제어 전류값을 기초로 하여 상기 유압 펌프의 펌프 제어 선도 및 펌프 효율 맵에서 상기 엔진에 인가되는 부하를 예측하는 단계, 및 상기 엔진에 인가되는 상기 예측된 부하 및 상기 회전수를 기초로 하여 배기가스 재순환 장치(EGR) 밸브 및 쓰로틀 밸브의 개도량을 제어하는 단계를 포함할 수 있다.
