The present invention relates to a method for detecting combustion misses in a multi-cylinder internal combustion engine, having at least one first engine control unit which controls at least the injection and firing of a first subset of the cylinders of the internal combustion engine, and having at least one further engine control unit which controls the injection and firing of a further subset of cylinders and in which the detection of combustion misses for the first and the further subset of cylinders is additionally carried out; the control units using an engine control program which is interrupted by interrupt routines, in phase-synchronism with the rotational movement of the crankshaft, in which at least the data required for the injection and firing are processed; and in which method the detection of combustion misses is based on establishing and evaluating crankshaft segment times in which the crankshaft covers an associated circle-segment angle range; and the crankshaft segment times likewise being established and evaluated in particular interrupt routines, the crankshaft segment times being established and evaluated for the further subset of cylinders in the interrupt routines in which their firing is controlled, and the crankshaft segment times for the first cylinder being established and evaluated in certain additionally generated interrupt routines.
