A method for determining a rotational speed of a drive shaft of an internal combustion engine

摘要

A method for determining a rotational speed (nx) of a drive shaft (13) of an internal combustion engine (10) to at least one later point in time (tx), wherein the rotating drive shaft (13) different rotational positions (phi11, phi12; phi21, phi22) at different points in time (t11, t12; t21, t22), of at least two rotational positions (phi11, phi12; phi21, phi22) a last average rotational behavior (m1, m2; mi) can be determined, and from this an average rotational speed (nx) to at least one later point in time (tx) is closed.
