Abstract: To determine a state of motion of a vehicle comprising an acceleration sensor, a vibration signal is determined as a function of a measurement signal of the acceleration sensor. The vibration signal is representative of vibrations of the vehicle. A determination is made as to whether the vehicle is at a standstill or whether the vehicle is moving, such determination made by comparing the vibration signal with at least one pre-determined threshold value.

Abstract: A series (FA) of scanning values (AW) is transformed into a series (FT) of transformation values (TW) by adding one respective transformation value (TW) representing a current scanning value (AW) of the series (FA) of scanning values (AW) to the series (FT) of transformation values (TW) if the current scanning value (AW) of the series (FA) of scanning values (AW) deviates from a given reference scanning value (REF) at least by a given net value (MDIFF). The current scanning value (AW) of the series (FA) of scanning values (AW) which deviates from the given reference scanning value (REF) at least by the given net value (MDIFF) is predefined as the given reference scanning value (REF) for subsequent current scanning values (AW). A moving average (M) is determined in accordance with the series (FT) of transformation values (TW). Pulses (IMP) are recognized in accordance with the moving average (M).
