Abstract

A method for identifying and correcting errors in time measurement on rotating shafts, particularly on crankshafts or shafts connected thereto in internal combustion engines, whereby the shafts are provided with marks which are scanned with sensors. The segment times required by the shaft to rotate about a defined angular distance are measured and compared with a reference segment.
