Abstract (en)

[origin: WO2011098445A2] The invention relates to a method for predetermining a motion state (BZn+1) of a drive shaft (222) of an internal combustion engine (210) on the basis of previous motion states (BZn, BZn-2) of the drive shaft (222), wherein properties (tn-2, ?n-2) allocated to a first previous motion state (BZn-2) and properties (tn, ?n) allocated to a second previous motion state (BZn) are used and the drive shaft (222) assumes periodically recurring angular positions (fn-2, fn, fn+2; fn-1, fn+1). The invention is characterized in that a future motion state (BZn+1) and the properties (tn+1, fn+1) allocated thereto of the drive shaft (222) 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 (fn+1) of the determined future motion state (BZn+1)of the drive shaft (222) is not equal to an angular position (fn-2, fn) of the first and second previous motion state (BZn, BZn-2).
