Abstract
A method for determining a future rotational speed of a rotating drive shaft of an internal combustion engine is described, in particular while the internal combustion engine coasts after being turned off, the future rotational speed being calculated from a course of measured rotational speeds. To predict a future rotational speed of the drive shaft of the internal combustion engine as accurately as possible, instantaneous rotational speeds measured at different rotational positions of drive shaft are evaluated.
