Abstract
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.
