A method for starting an internal combustion engine, in which a control unit starts at least one function at a specific crankshaft angle, the function being shifted from the start of the internal combustion engine until a final condition is reached by a relative angle to a later crankshaft angle.

Method for starting an internal combustion engine

A method for determining the crankshaft position of an internal combustion engine is described with which, in the event of failure of the crankshaft sensor, the crankshaft position may be determined with relative precision at all times. For this purpose, the camshaft position is continuously detected by an absolute angle sensor, preferably in a defined time grid. By analyzing the camshaft positions detected in that way, a value for the instantaneous crankshaft position is determined.
