  • Method and device for filtering a signal
    Publication number: 20040254656
    Abstract: A method and a device are described for filtering a variable. A first filtering arrangement is used for forming an output variable as a function of an input variable, the first filtering arrangement having at least a delaying effect. The input variable of the first filtering arrangement is corrected using a correcting variable which is obtained by starting from the input variable of the first filtering arrangement and by filtering, using a second filtering arrangement.

  • Method and device for consistent bi-directional evaluation of characteristics diagram data
    Publication number: 20040176886
    Abstract: A method and a device (10) for consistent bidirectional analysis of engine characteristics map data in an engine characteristics map are described. The engine characteristics map data represents interlinked technical variables. In this method, first a characteristic curve representing the interdependence of two of the technical variables is determined. This characteristic curve forms the basis for additional conversions in bidirectional analysis of the particular engine characteristics map.
