In a fuel efficiency improvement method applied to a hybrid vehicle (1) of the present invention, when a driving prediction controller (1-3A) is driving according to road conditions confirmed by a camera of an ADAS (50), a turbocharger (30) and an EGR system (40) are controlled under an SOC threshold condition of a battery (10-3), so that additional energy regeneration is allowed through a negative torque section in a motor (10-2) in a power generation control state. Therefore, by opening a turbo vane (33), a waste-gate (30-1), and an EGR valve (40-1), a vehicle energy recovery is maximized by reducing the energy consumed when driving on a road where energy recovery is most effective due to deceleration or a lower slope while driving. The present invention includes a step of allowing additional energy regeneration.
본 발명의 하이브리드 차량(1)에 적용된 연비개선 방법은 주행예측 컨트롤러(1-3A)가 ADAS(50)의 카메라로 확인된 도로 조건에 따른 타행 주행 시 배터리(10-3)의 SOC 임계값 조건에서 터보차저(30)와 EGR 시스템(40)을 제어하여 발전제어 상태의 모터(10-2)에서 부(Negative) 토크 구간을 통해 추가 에너지 회생이 이루어지도록 함으로써 터보 베인(33), 웨이스트 게이트(30-1) 및 EGR 밸브(40-1)의 개방으로 주행 중 감속하거나 경사가 낮아져 에너지 회수가 가장 효과적인 도로 주행 시 소모되는 에너지를 최대한 줄여 차량 에너지 회수가 최대화되도록 함에 그 특징이 있다.
