Abstract

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.

subjecting the scanned information to a data reduction to produce reduced data;

storing the reduced data;

viewing the curve, in a context of the data reduction, in a time raster of a multiple of the scanning period;

within individual raster increments, determining at least one characteristic variable of the curve; and

selecting the raster increments so as to vary as a function of at least one further characteristic variable of the curve within one raster increment.

2. The method as recited in claim 1, wherein:

the scanned information includes operating data of a motor vehicle.

3. The method as recited in claim 1, further comprising:

determining at least one of maximum values and minimum values of values of the scanned information within the raster increments, as the at least one characteristic variable of the curve.

4. The method as recited in claim 1, further comprising:

determining an average value of values of the scanned information within the raster increments, as the at least one characteristic variable of the curve.

5. The method as recited in claim 1, further comprising:

selecting the raster increments so as to vary as a function of a standard deviation of values of the scanned information of the curve of the scanned information within one raster increment.

6. The method as recited in claim 4, further comprising:

selecting the raster increments so as to be so small that the standard deviation does not exceed a specifiable value.

7. The method as recited in claim 1, further comprising:

selecting the raster increments so as to vary as a function of a distance of one of a maximum value and a minimum value from an average value of values of the scanned information within one raster increment of the curve.
