Abstract:
A method for controlling an engine connected to an electric machine having a stator and a rotor, said engine having a camshaft and a crankshaft which is nonrotatably connected to the rotor, said method comprising:detecting the current angular position of the rotor with respect to the stator, transmitting the current angular position of the rotor to a control unit of the electric machine, determining a top dead center signal of the crankshaft in the control unit of the electric machine based on the angular position of the rotor, wherein said top dead center signal is one of a top dead center for ignition and a top dead center for gas exchange, determining the corresponding camshaft angle in the control unit of the electric machine using the detected current angular position of the rotor and the top dead center signal, transmitting the camshaft angle to a control unit for the engine, and storing the detected current angular position of the rotor and the corresponding camshaft angle at least temporarily in a memory unit.
