본 발명은, 내연기관과 하나 이상의 추가 기계, 특히 전기 기계를 구비한 하이브리드 파워 트레인의 내연기관을 시동하기 위한 방법 및 장치에 관한 것이며, 이 경우 내연기관과 추가 기계 사이에 배치되는 분리형 클러치와 내연기관의 현재 크랭크 샤프트각을 검출하기 위한 크랭크 샤프트각 센서 장치가 제공된다. 고전압 배터리(208)가 실질적으로 방전된 경우 내연기관(101)을 시동하기 위한 다음 단계들: a.) 분리형 클러치(102)가 개방되거나, 이미 개방된 단계; b.) 추가 기계(103)가 가속되는 단계; c.) 추가 기계(103)의 가속 과정이 종료된 후에, 내연기관(101)도 마찬가지로 가속되도록 분리형 클러치(102)가 체결되는 단계; d.) 크랭크 샤프트각 센서 장치(209)가 바람직한 크랭크 샤프트각을 제공하는 즉시, 내연기관(101)이 직접 시동에 의해 시동되는 단계를 실행하는 수단들이 제공된다.
A method and a device are described for starting an internal combustion engine of a hybrid drive train, having an internal combustion engine and at least one additional machine, in particular an electric machine, a separating clutch, which is situated between the internal combustion engine and the additional machine, and a crankshaft angle sensor for detecting the instantaneous crankshaft angle of the internal combustion engine being provided. Arrangements are provided to perform the following operations to start the internal combustion engine when a high-voltage battery is essentially discharged, including a) the separating clutch is or has already been disengaged, b) the additional machine is accelerated, c) after conclusion of the acceleration operation of the additional machine, the separating clutch is engaged, so that the internal combustion engine is also accelerated, d) as soon as the crankshaft angle sensor system supplies a favorable crankshaft angle, the internal combustion engine is started by direct start.
