Abstract
The invention relates to a method for providing an indication of movement from a sensor signal from a position transmitter (9), wherein the indication of movement indicates a speed of movement, wherein the sensor signal from the position transmitter (9) generates an edge following a movement via a particular path range having the following steps:—a pulse duration (dT) is ascertained (S1) as the interval of time between the last two provided edges of the sensor signal;—depending on whether a period which corresponds to the pulse duration (dT) has elapsed since the last provided edge of the sensor signal, an indication which is dependent on the pulse duration (dT) or an indication which is dependent on the period since the last edge of the sensor signal is provided (S4, S6) as an indication of movement.
