Definitions

  • the invention relates to an electronic bucking device for internal combustion engines with electronic fuel injection in motor vehicles, especially diesel engines, with a fuel device that can be predetermined by an accelerator pedal supplied quantity request signal and with one of the the vibration signal superimposed on the internal combustion engine derived negative feedback of the fuel injector supplied quantity component signal.
  • the two separate filters Functions quantity damping and bucking damping decoupled, so that they can be set and optimized independently of one another, whereby the desired simplified application is achieved becomes.
  • the filter functions are easier and easier to understand and optimize.
  • For the quantity damping has a PDT1 filter and for the bucking damping a D2T2 filter as am proven best.
  • the amplitude and frequency of the jerking vibrations are at a vehicle strongly dependent on the operating point, the essential Influencing factors the respective gear stage and the Engine speed are.
  • the filter parameters over this Characteristic maps at least depending on the speed of the internal combustion engine and / or the respective gear stage of the Gear can be specified to a in all operating conditions to achieve optimum bucking damping in each case.
  • At least one switching device for switching between a map-dependent Specification of filter parameters and a specification of fixed Provide filter parameters, with a switchover of the switching device on the fixed filter parameters for external Volume interventions are provided that provide a quick response the fuel injector, and where the fixed Filter parameters reduce the filter effect of the filters or eliminate. This ensures, for example, that when using an anti-slip control device (ASR) the Internal combustion engine reacts instantaneously.
  • ASR anti-slip control device
  • the bucking device according to the invention is suitable especially for diesel engines with electronically controlled injection pumps.
  • FIG. 1 shows an electronic one Vibration damping device for diesel engines with one electronically controlled injection pump 10.
  • the invention is however also for diesel engines with another electronic Fuel injector suitable, as well as general for internal combustion engines, for example also for gasoline engines, with electronic fuel injection. Instead of Injection pump 10 then enters the respective fuel injection device.
  • the desired quantity signal Me w generated by an accelerator pedal 11 is fed as a control signal to the injection pump 10 via a PDT1 filter 12 and via a sum point 13 arranged behind the PDT1 filter 12.
  • a speed signal N which is filtered by a D2T2 filter 14 and which is picked up by a speed sensor (not shown) on the diesel engine, is also fed back.
  • the speed signal filtered in the D2T2 filter 14 is subtracted from the filtered desired quantity signal Me d at the output of the PDT1 filter 12 as the quantity component Me R generated by the jerky vibration.
  • the difference results in the summed quantity signal Me S, which is supplied to the injection pump 10 as an effective quantity control signal.
  • k M is the step constant and T M is the time constant of the transfer function or the PDT1 filter 12.
  • p is the complex frequency variable usually used in transfer functions.
  • the transfer function of the D2T2 filter 14 is shown in FIG. 3 in the form of a bottom diagram.
  • k R is the gain and T R is the time constant of serving as Ruckeldämpfers D2T2 filter 14.
  • D2T2 by filtering the speed signal N is obtained a bucking absorbing quantity component Me R, which is removed in the manner already described from the filtered quantity request signal Me D to obtain the summed signal and actual amount S Me.
  • the filter constants T M , k M , T R and k R are also referred to below as TM, KM, TR and KR.
  • the four filter parameters that can be defined by the characteristic diagrams 15 to 18 are applied to inputs of the filters 12 and 13 via switching stages 19 to 22, via which the filter parameters can be specified.
  • the switching positions of the switching stages 19 to 22 shown are the switching positions for normal driving, in which the filter parameters TM NG , KM NG , TR NG and KR NG, which are dependent on the influencing variables G and N, of the maps 15 to 18 on the filter inputs defining the filter parameters Filters 12 and 14 are present.
  • a signal CANME is sent to the switching stages 19 from a central engine control or from the individual control components, 22 supplied, which causes a switchover to the other switching state.
  • fixed filter parameter values TM CAN , KM CAN , TR CAN and KR CAN are applied to filters 12 to 14 via these switching stages 19 to 22.
  • filter constants independent filter constants cause a reduction in the filter effect of these filters 12, 14, so that rapid quantity signal changes can be implemented.
  • filter constants can also be selected so that the filters are completely ineffective. For example, generally useful filter properties of the PDT1 filter 12 are obtained with values of the step constant KM between 0 and 1. If KM is now set to 1, there is no longer any filter effect.
  • the filter constants are only partly via characteristic maps to specify.
  • maps 15 to 18 predefined influencing variables only dependent filter constants partly through switching stages 19 to 22.
  • the switching stage 19 omitted, so that only a switchover of the Jump constants KM is possible, but this is sufficient in individual cases.
  • the Filters 12 and 14 also have modified filter properties, if this proves to be sufficient or advantageous in individual cases prove.
  • the influencing variable-dependent specification of filter constants about maps is also related to others Filter or filter with other filter properties from Advantage and importance.
  • bridging switches can also be used for filters 12 and 14 occur by a corresponding Control signal CANME can be actuated, i.e. when they occur of such a signal, the filters 12 and / or 14 bridged.
