Abstract
A method for determining an orientation of a movable device. The method includes the steps: determining an extent of the change of the orientation on the basis of data of at least one first sensor unit, comparing the extent to a predetermined threshold value, if the threshold value is exceeded, switching on a second sensor unit if it is in a switched-off state and determining the orientation with the aid of the first sensor unit and the second sensor unit, at an undershoot of the threshold value or if the extent is equal to the threshold value, switching off the second sensor unit, if it is in a switched-on state, and ascertaining the orientation with the aid of the first sensor unit.
