Definitions

  • the invention relates to a method and a device for controlling the air supply to an internal combustion engine.
  • Such a method or such a device is known from DE-OS 26 54 455.
  • An electrical controller is proposed there, which generates a control signal for controlling the air supply to the internal combustion engine via a throttle valve as a function of a predetermined and a measured operating parameter of the motor vehicle.
  • a delay or filter element is provided in the control line, which is to ensure a smooth transition of the measured parameter value to the specified value when the specified value changes.
  • This delay or filter element delays the timing of the control signal of the controller device in the event of a change in the predetermined value that is greater than a threshold value, while the control signal reaches the throttle valve unchanged in the event of changes below the threshold value.
  • the rate of change of the control element position or the control signal for the control element for controlling the air supply can be changed by influencing a filter characteristic or the transmission behavior of a filter in accordance with the value or signal to be filtered and the filtered value or signal.
  • DE-OS 27 51 125 discloses a system for electronically regulating the throttle valve position of an internal combustion engine as a function of a value specified by the accelerator pedal. To improve the Operating behavior of the internal combustion engine is limited by a filter arranged between the position controller and throttle valve control, the rate of change of the throttle valve position.
  • the procedure according to the invention has the advantage that smoothness and driving comfort of the motor vehicle are improved, in particular in the area of the idling state, since changes of smaller amplitude and higher frequency do not take effect, while the control system can follow changes of larger amplitude at high speed. Another advantage is that the procedure according to the invention makes it possible to achieve the improvements without interfering with the controller structure.
  • FIG. 1 shows a block diagram of a device for controlling the air supply to an internal combustion engine

B. via an idle switch in the throttle valve or in the accelerator pedal, detected idle state instead. In the case of an electronic accelerator pedal system, the default value is formed on the one hand as a function of the accelerator pedal position and on the other hand in the idle state in accordance with the idle control.
  • the position of the actuating element 20 determined by the position transmitter 22 is compared in the comparison point 54 with the preset value and a difference signal between the preset and actual value is sent to the position controller 32 via the line 55, which, depending on this difference signal, outputs a preset value for the position via its output line 56 of the actuator 20 generated.

  • the filter module 54 is a low-pass analog design with changeable time constants or digital design with changeable filter constants.
  • the filter effect or characteristic or transfer behavior of the filter module 34 is determined by the difference generator 36. Depending on the difference between the value to be filtered (default value of the controller) on line 56 and the filter output signal as a filtered signal on line 58, this forms an output signal indicating the size of the difference, which is output via line 60 to filter module 34.
  • the filter characteristic is set such that the filter constants are changed with increasing size of the difference in such a way that the effect of the filter module 34 on the time profile of the value to be filtered (default value) decreases with increasing difference.

  • the filter constants C I are initialized in a block 100.
  • the default value output by the controller is now measured as the value to be filtered and the filtered value in block 104 is calculated on the basis of the measured default value and the filter constants loaded in the initialization step.

  • the horizontal axes denote the time, the vertical axes the signal level of the value to be filtered or filtered.
  • FIG. 3a shows changes in the small amplitude and higher frequency of the value to be filtered. If there are small differences between the value to be filtered and the value filtered, the effect of the filter is strong, so that the changes in the value to be filtered do not, or hardly, affect the control signal of the actuating element 20 and thus the position of the throttle valve. In contrast, a dynamic operating case is presented in FIG. 3b.
  • the change in the value to be filtered has a large amplitude, the filtered value reacts quickly to this change and slows down its rate of increase depending on the difference between the value to be filtered and the filtered value by appropriate variation of the filter effect.
