| 摘要 |
The invention relates to a method and a control system for driving an electric motor ( 4 ) coupled with a crankshaft ( 2 ) of an internal combustion engine, in order to position the crankshaft ( 2 ) at a starting angle, wherein the control system comprises: a detection device ( 7 ) for receiving and/or determining a position angle and/or the rotational speed of the crankshaft ( 2 ), and a control unit ( 5 ) which is capable of driving the electric motor ( 4 ) in a closed loop control mode dependent on the rotational speed of the crankshaft and of positioning the crankshaft ( 2 ) at said starting angle after the internal combustion engine ( 1 ) is stopped, so that, in the case of a subsequent start, the internal combustion engine ( 1 ) is started from this starting angle, wherein the control unit ( 5 ) is designed so as to drive the electric motor ( 4 ) according to an open loop control mode, below a prespecified rotational speed limit independently of the rotational speed in an open loop control, so that the crankshaft ( 2 ) is set to the starting angle.
