Abstract

A device for monitoring a transverse acceleration sensor located in a vehicle and detecting a first transverse acceleration quantity. The device includes a processing device that has at least one filtering device used to filter the first transverse acceleration quantity, yielding a filtered transverse acceleration quantity. A second transverse acceleration quantity is determined by determining device as a function of wheel speed quantities detected by a corresponding detecting device. A comparison between the filtered transverse acceleration quantity and the second transverse acceleration quantity is carried out in a monitoring device to monitor the transverse acceleration sensor.
