Abstract
In a method for determining an idle state: acceleration values are ascertained as a function of three spatial directions; a comparison value is generated from the acceleration values for each of the three spatial directions; each of the comparison values is compared with a threshold value; an interrupt signal is generated if the comparison value is less than the threshold value for each of the three spatial directions; and an electronic component is switched from a power saving state to an operating state as a function of the interrupt signal.

A method for determining an idle state, comprising:
- ascertaining acceleration values as a function of three spatial directions;
- generating a comparison value from the acceleration values for each of the three spatial directions;
- comparing each of the comparison values with a threshold value;
- generating an interrupt signal if the comparison value is less than the threshold value for each of the three spatial directions;
- and
- switching at least one electronic component from a power saving state to an operating state as a function of the interrupt signal.
A system for determining an idle state, comprising:
- an acceleration sensor unit;
- an evaluation unit;
- and
- an electronic component;
- wherein the acceleration unit is adapted to ascertain acceleration values along three spatial directions, the evaluation unit is adapted to generate a comparison value from the acceleration values for each of the three spatial directions and to compare each of the comparison values with a threshold value;
- and
- wherein the evaluation unit is adapted to generate an interrupt signal if the comparison value is less than the threshold value for each of the three spatial directions, and the electronic component is adapted to change its operating mode from a power saving state to an operating state as a function of the interrupt signal.
