  • Method and control system for positioning a crankshaft of an internal combustion engine
    Patent number: 7261076
    Abstract: 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
