Abstract
An adaptation method for correcting tolerances of a transducer wheel includes determining a correction factor for each individual tooth or each segment of the transducer wheel by measuring angular speed while taking into account both production tolerances and variations from one manufactured part to another of its kind as well as noncentral support of the transducer wheel on the shaft. The correction factor also compensates for a mass moment caused by a piston and a connecting rod. In an adaptation algorithm, a periodic disturbance by a gas moment caused by varying cylinder pressures and a moment fed back from the road are taken into account.
