Abstract

In a method for ascertaining a rotational direction of a rotating body, one rotational direction and one rotational speed value which indicates the rotational frequency of the rotating body are ascertained in each of multiple measurements. The rotational speed values of the multiple measurements are compared to each other, and a rotational direction of the rotating body is ascertained from the measured rotational directions and the comparison of the rotational speed values.
