ABSTRACT:
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.
