A method for controlling a hybrid starter and generator for improving fuel efficiency, which is applied to an eco-friendly vehicle, performs HSG torque-output limit control divided into an HSG regeneration mode and an HSG driving mode, wherein the HSG regeneration mode includes former regeneration torque output control in which the engine RPM is switched to the regenerative torque output of an HSG (3) for about 1 second at the start of an engine idle by a controller (10) to charge a battery (7), and latter regeneration torque output control in which the engine RPM is switched to the regeneration torque output of the HSG (3) for about 5 seconds after 1 second to continue the charging of the battery (7), and the HSG driving mode restricts an output of the HSG (3) after restricting torque of the HSG (3). In the regenerative torque output control of the HSG (3), the engine energy that is wasted by the friction loss after the start of the engine idle is used for charging the battery (7), so an additional fuel consumption improvement effect is obtained.
본 발명의 환경차량에 적용된 하이브리드 시동 발전기 제어 방법은 컨트롤러(10)에 의해 엔진아이들(Eng idle)의 시작시점에서 약 1초 동안 엔진 RPM이 HSG(3)의 회생토크출력으로 전환되어 배터리(7)를 충전시켜주는 전기회생토크출력제어와 1초 이후 약 5초까지 엔진 RPM을 HSG(3)의 회생토크출력으로 전환하여 배터리(7)의 충전을 지속시켜주는 후기회생토크출력제어로 이루어진 HSG 회생모드, HSG(3)의 토크 제한 후 HSG(3)의 출력제한으로 이어지는 HSG 구동모드로 구분된 HSG 토크-출력제한제어가 수행됨으로써 HSG(3)의 회생토크출력제어에서 엔진 아이들 개시 후 마찰손실로 버려지던 엔진 에너지를 배터리(7)의 충전에 사용하여 추가 연비개선 효과가 얻어지는 특징을 갖는다.
