Abstract
The invention relates to a method for predetermining a motion state (BZn+1) of a drive shaft () of an internal combustion engine () on the basis of previous motion states (BZn, BZn−2) of the drive shaft (), wherein properties (tn−2, ωn−2) allocated to a first previous motion state (BZn−2) and properties (tn, ωn) allocated to a second previous motion state (BZn) are used and the drive shaft () assumes periodically recurring angular positions (φn−2, φn, φn+2; φn−1, φn+1). The invention is characterized in that a future motion state (BZn+1) and the properties (tn−1, φn+1) allocated thereto of the drive shaft () are determined in an angular position on the basis of the first evaluated previous motion state (BZn−2) and the second evaluated previous motion state (BZn), wherein the angular position (φn+1) of the determined future motion state (BZn+1)of the drive shaft () is not equal to an angular position (φn−2, φn) of the first and second previous motion state (BZn, BZn−2).
