ABSTRACT:
A method and device for determining a correction value for a measured segment time, which a shaft of an internal combustion engine, in particular a crankshaft, needs in order to rotate about a defined angular range, evaluate the following relationship in order to determine correction values for individual cylinders:in-line-formulae description="In-line Formulae" end="lead"?AZn=[(TGn−TG0)−(n/z)*(TG0′−TG0)]/[TG0+(n/z)*(TG0′−TG0)],in-line-formulae description="In-line Formulae" end="tail"?wherez is the number of cylinders of the internal combustion engine,n is the number of the cylinder currently under consideration,TGnis the measured segment time of the cylinder with the number n,TG0is the measured segment time of a reference segment of a reference cylinder,TG0′is the segment time of the reference segment of the reference cylinder measured two crankshaft rotations after the segment time TG0, andAZnis a correction value for the segment time of the cylinder with the number n.
