본 발명의 하이브리드 차량(100)에서 구현하는 연비 개선을 위한 모터 충전 제어 방법은 운전자 제동 시, HCU(8)의 회생제동 실행 파워에 맞춰 엔진 온/오프(On/Off), 엔진 클러치 접합/해제, P0/P1 모터 충전 미 수행/수행 중 어느 하나를 선택 조합하고, 제동 파워와 제동 시간에 따른 차량 감속 수준별로 P2 모터(2)의 회생제동 에너지 회수에 더하여 P0 모터(4a), P1 모터(4b)및 P0/P1 모터(4a,4b)의 조합 중 하나로 회생제동 에너지를 추가 회수하여 에너지저장장치(5)를 충전함으로써 복수개의 P0/P1/P2 모터 각각에 대한 충전 제어가 제동요구파워 수준에 따른 감속수준별 가변제어로 최적화됨으로써 유압 제동으로 소모되는 회생제동 에너지를 최대한 회수하는 특징이 구현된다.
In a method of controlling charging by a motor to improving fuel efficiency of a hybrid vehicle, at least one of turning-on of an engine, turning-off thereof, engagement of an engine clutch, disengagement thereof, performing of charging by P0 and P1 motors, and non-performing of charging by the P0 and P1 motors are selectively combined. In addition to regenerative braking energy recovered by the third motor, regenerative braking energy is recovered by a P0 motor, P1 motor, and a combination of the P0 and P1 motors according to a level of deceleration of the hybrid vehicle that varies with braking power and braking time, and an energy storage system is charged with the recovered regenerative braking energy. Control of charging by each of the P2, P0, and P1 motors is optimized as variable control on a per-deceleration level basis that varies with a level of a power required for braking.
