Abstract:
Electronic bucking damping device for an internal-combustion engine with an electronic fuel injection, said electronic bucking damping device having a quantity request signal definable via an accelerator pedal and being fed to a fuel infection device, as well as a quantity component signal derived from bucking vibration superimposed on a rotational speed signal of the internal combustion engine and being supplied in an inverse-coupled manner to the fuel injection device, wherein said quantity request signal is present by way of a PDT1-filter at a summation point connected with a control signal input of the fuel injection device, and further wherein said rotational speed signal filtered by way of a separate D2T2-filter is present at this summation point as the quantity component signal to be subtracted;wherein for defining at least a portion of the filter parameters for the filters, characteristic diagrams are provided; andwherein the filter parameters are defined by way of the characteristic diagrams at least as a function of the rotational speed of the internal-combustion engine and/or of the respective existing gear position of a transmission.
