Abstract

A method is provided for checking a sensor value of a MEMS sensor. In the process, an output signal of the MEMS sensor is detected and the sensor value is ascertained as a function of the output signal. In addition, frequency components of the output signal are examined and a determination is made as to whether the ascertained sensor value is reliable or unreliable as a function of the examination of the frequency components. If the sensor value is determined to be unreliable, the sensor value is discarded or provided with a lower weighting, or a warning it output relating to the unreliability of the sensor value or an item of information about the unreliability of the sensor value is stored.
