ABSTRACT:
An electronic bucking damping device is provided for internal-combustion engines with an electronic fuel injection in motor vehicles, particular for diesel engines. By way of an accelerator pedal, a quantity request signal is given and is fed by way of a PDT1-filter to a summation point connected with the control signal input of the fuel injection device. A rotational speed signal is filtered by way of a D2T2-filter and is subtracted in the summation point from the filtered quantity request signal. Via the filtered quantity request signal, load jumps and a related uncomfortable vehicle handling are avoided, and via the inverse coupling of the bucking vibration superimposed on the rotational speed signal, the bucking is damped or prevented. Using the two separate filters, the quantity damping and bucking damping functions are uncoupled, which simplifies the application.
