A method and a device for recording the curve of information. The information
is
scanned using a specifiable scanning period. The information is specifically the
operating data of a motor vehicle. The scanned information is subjected to a data
reduction, and then the reduced information is stored. To record the curve of relevant
digital information, in particular, of the operating data of a motor vehicle, so
as to use the least possible storage space, it is proposed that, in the context
of the data reduction, the curve of the scanned information be viewed in a time
raster of a multiple of the scanning period, and, within the individual raster
increments, at least one characteristic variable of the curve of the scanned information
be determined. The device is advantageously a component part of a control device
for controlling/regulating specific motor-vehicle components or of an operating-
or accident-data recorder of a motor vehicle.
