A method determines a rotational speed of a driveshaft of an internal combustion engine. The rotating driveshaft assumes different rotary positions at different times. An average gradient of rotary speed for the driveshaft is determined at at least two rotary positions. Subsequently, an average rotational speed for the driveshaft is obtained from a past average gradient of rotary speed at at least one later point in time.

摘要:
A method for determining an average rotational speed of a rotating transmission shaft of an internal combustion engine to a rotational position is described, the rotating transmission shaft taking on various rotational positions and having an actual instantaneous rotational speed at a first time in the rotational position. At a first approximation in a first step, an approximated average rotational speed is determined, as the difference of the actual rotational speed at the first time and in the rotational position, and the product of a weighted amplitude and an angle-dependent amplitude factor.
