Definitions

  • the invention relates to a method and a device for filtering a signal according to the preambles of the independent claims.
  • a method and a device for filtering a signal is known for example from DE 195 37 787.
  • the driver's desired amount is filtered by a specialistssformers.
  • the filtering is designed such that e.g. rapid change in the desired quantity (pedal value) does not have an undiminished effect on the metering of fuel, thus avoiding the excitation of vehicle longitudinal vibrations.
  • Such filtering to dampen the excitation of systems have the disadvantage that they generate a following error in a ramp-like change in the input variable. That is, the output follows the input only delayed. This has an effect, for example, in an application in an internal combustion engine by a reduced drive torque.
  • US Pat. No. 5,775,293 discloses filtering a variable with a first filter medium to form an output variable as a function of the input variable.
  • a second filter means predetermines a coefficient which determines the transmission behavior of the first filter means. This means that, based on the input variable of the first filter means, coefficients are determined with which the transmission behavior of the first filter means is influenced. This procedure is based on the task of greatly attenuating small minor pedal value changes, while in the case of large changes an as instantaneous transmission of the signal as possible should take place.
  • the procedure according to the invention offers the advantage that corresponding tracking errors can be compensated without that restrictions of the filter effect must be taken into account, in particular in the case of sudden changes in the input quantity.
  • FIG. 1 shows the basic structure of a Kraftstoffzumesssystems
  • Figure 2 is a block diagram of the procedure according to the invention.
  • the invention is illustrated below using the example of a fuel quantity signal in a self-igniting internal combustion engine.
  • the invention is not limited to this application. It can also be used for other signals, in particular for signals used in the control of internal combustion engines.
  • the method is suitable for signals that influence or characterize the emitted torque.
  • signals are, for example, a fuel quantity signal, signals for controlling power-influencing actuators, a quantity request signal, the output signal of an accelerator pedal or a speed signal.
  • FIG. 1 shows the basic structure of a fuel metering system of an internal combustion engine.
  • 10 is an accelerator pedal position transmitter and denoted by 11 a speed sensor.
  • a set point control 12 is connected to the accelerator pedal position sensor and the speed sensor 11.
  • the output signal MEW the setpoint control, the driver's desired amount
  • the output signal MEF of the guide former 13 and the output signal MES of the disturbance regulator 14 are superimposed in an addition point and form the quantity signal MEA, which is fed to an actuating device 15 , Depending on this signal MEA, the engine not shown, a corresponding amount of fuel is metered.
  • the driver's desired amount MEW which is required to provide the driver desired performance.
  • this signal is fed directly to the actuator 15.
  • the adjusting device 15 converts this signal into a drive signal for acting on the corresponding actuating elements. For example, in the case of series pumps, it is provided that an adjusting control loop adjusts the rack position to a corresponding value.
  • the actuator 15 outputs a drive signal for a quantity-determining solenoid valve or a piezoelectric actuator.
  • the driver's desired signal MEW is filtered by means of a guide former 13.
  • the guide former 13 has at least one retarding effect.
  • filters with PT1 behavior can be used. It is particularly advantageous if filters are used as guide formers, which comprise further components.
  • the filter 13 which forms the guide former, has at least delaying behavior, for example a T1 element, a tracking error occurs with certain changes in the input variable of the filter 13. That is, the output follows the input only delayed.
  • this tracking error is remedied by the fact that at the input of the filter, a correction value is switched, which is formed on the basis of the input variable.
  • the input quantity is derived in time, i. differentiated and then weighted with a particular specifiable value.
  • This weighting factor is preferably specified depending on the transmission behavior of the filter to be corrected.
  • the time derivative of the input variable is limited in order to maintain the filter effect with rapidly changing input variable despite the measures against lag errors.
  • the actual filter of the handheldsformers is referred to as the first filter 100.
  • the input variable MEW of the guide former 13 reaches the first positive-sign to a node 125 and the second filter 110.
  • the output signal of the node 125 reaches the first filter 100.
  • the output signal of the second filter 110 passes via a limiter 112 to a second node 115.
  • the output signal of the node 115 preferably passes with a positive sign to the node 125.
  • the output signal of a factor specification 120 is applied.
  • the output signal of the first filter 100 forms the output variable MEF.
  • the limiter 112 is arranged after the connection point 115. This means that the limiter 112 limits the correction variable with which the input of the first filter 100 is corrected at the node 125.
  • the input quantity additionally passes via an amplifier 140 to a connection point 130, at the second input of which the output variable of the first filter 100 is present.
  • These two quantities then form the output variable MEF.
  • the second filter 110 is preferably designed as a differentiator. At least the second filter 110 comprises a differentiating component.
  • the second filter may also be designed as a PD element or as a DT element.
  • the output variable of the second filter 110 is limited by the limiter 112 to the maximum permissible values in order to ensure the filter effect in the event of a rapid, in particular step-like, change in the input variable MEW.
  • the limiter 112 is dimensioned such that the limitation is ineffective with slowly changing input quantity and the filter 110 provides an uninfluenced contribution to the correction of the input variable of the first filter 100.
  • the second filter 120 With slow changes in the input, the second filter 120 has a relatively large influence on the filtered quantity.
  • the limitation In the case of step-shaped, ie with rapid changes of the input variable, the limitation is effective, whereby the corresponding contribution of the second filter 110 for correcting the input variable of the first filter is only small. With rapid changes in the input, the second filter 120 has a relatively small effect on the filtered size. In this case, the first filter 100 has a great influence on the filtered size.
  • the output signal of the second filter 110 is weighted with a predefinable weighting factor of the factor setting 120.
  • the weighting factor is specifiable in particular as a function of the transmission behavior of the first filter 100.
  • the first filter 100 has the transition function: K / T * s + 1
  • the size T is usually referred to as a delay time constant and the size K as a proportional gain.
  • the factor of the factor specification 120 is preferably identical to the time constant T. This means that the output signal of the second filter 110, which is limited by the limiter 112, is multiplied by the factor of the factorization factor 120, i. with the delay time constant T of the first filter 100, is weighted.
  • the amplifier 140 has the amplification factor V.
  • the input quantity MEW of the first filter 100 is corrected as a function of the input quantity MEW of the first filter 100.
  • a correction variable for the correction of this input variable is determined.
  • the input variable is derived in time or differentiated and then weighted by a factor.
  • the factor is determined essentially by the transmission behavior of the first filter.
  • the factor preferably corresponds to the delay time constant T of the first filter.
