Correction of the Segment Time ts(n) (%DMDFOF, see )

The adaptation during fuel cut-off learns systematic differences of the segment times between the individual segments and uses the determined correction values to compensate segment specific variations. After the adaptation, the segment periods are nearly identical apart from the stochastic signal noise in the steady-state case.
