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.

    A method for controlling a hybrid starter and generator (HSG) is applied to an eco-friendly vehicle. The method includes HSG torque-output limiting control, and in particular, the HSG torque-output limiting control is divided into an HSG regeneration mode and an HSG driving mode in which output limitation of the HSG 3 is performed after torque limitation of the HSG 3. Furthermore, the HSG regeneration mode includes: a former regenerative torque output control in which an engine RPM is converted by a controller 10 into regenerative torque output of the HSG 3 for about 1 second when an engine starts idling to charge a battery, and a latter regenerative torque output control in which the engine RPM is converted into the regenerative torque output of the HSG 3 after 1 second to about five seconds to continue to charge the battery 7, and an HSG driving mode.
