Abstract

A device for monitoring an acceleration sensor located in a vehicle and detecting an acceleration quantity that describes an acceleration acting upon the vehicle. The device includes an averaging device that is used to generate a mean value of the acceleration quantity for a definable period of time. The mean value is largely independent of driving maneuvers performed with the vehicle. The device also includes a monitoring device in which a comparison between the mean value of the acceleration quantity and a threshold value is carried out to monitor the acceleration sensor.
