Definitions
- the invention relates to a method and an apparatus for Control an internal combustion engine according to the preambles of independent claims.
- Such a method and such a device for controlling a Internal combustion engine is known from WO 89/07709.
- a fault controller gives a leadership form depending on at least one driver request signal before a first value.
- a fault controller gives a second depending on one speed signal Value before.
- the fault controller in particular includes filtering. It is disadvantageous that the transmission behavior of the two filterings is constant for all operating states. Therefore it is with the Establishment according to the state of the art necessary that in the specification the filter parameters, the transmission behavior of the filtering determine a compromise that must be made all Operating states are taken into account and therefore not for all operating states is optimal. Therefore, vibrations cannot occur in all operating states be compensated.
- a motor vehicle poses due to the elastic suspension of the engine and undercarriage is a structure that can vibrate with interference to more or less damped Vibrations can be excited.
- interference for example, a jump in fuel consumption at Fuel metering into the internal combustion engine or one of moment jump caused outside, for example by a Pothole in the roadway.
- the vibrations caused by changes in speed or Relative movements between engine and body noticeable make are usually in the range between 1 and 10 Hz and are referred to as bucking.
- the invention has for its object in a method and a device for controlling an internal combustion engine of the type mentioned above, vibrations in all To largely compensate for operating conditions avoid. This task is carried out by the independent Characteristics characterized claims solved.
- the procedure according to the invention has the advantage that in Vibration largely compensated for all operating conditions can be.
- FIG. 1 shows the basic structure of a fuel metering system
- Figure 2 a flowchart to illustrate the invention Method.
- the invention is described below using the example of a self-igniting internal combustion engine shown.
- the invention is not limited to this application, it can also be used for other engines are used. at spark ignition engines will replace the Fuel quantity corresponding to the throttle valve position set.
- FIG. 1 is the basic structure of a Fuel metering system of a diesel engine shown.
- At 10 is an accelerator pedal position sensor and at 11 called a speed sensor.
- a setpoint control is 12 with the accelerator pedal position sensor 10 and the speed sensor 11 connected.
- the output signal MEW of the setpoint control the corresponds to the driver's desired quantity, comes to a Guide former 13.
- the speed signal N of the speed sensor 11 arrives at a disturbance variable controller 14.
- the output signal MEF of the guide former 13 and the output signal MES of the Fault controller 14 are superimposed in an addition point and form the quantity signal MEA, which an actuator 15 is forwarded.
- the MEA will not illustrated internal combustion engine a corresponding amount Fuel metered.
- a parameter controller 16 acts on the guide former 13 and the fault controller 14 with signals.
- the parameter control processes the output signal N of the speed sensor 11, the Signal V of a speed sensor 17, the signal KS one Coupling sensor 18 and the signals of others Control devices 19.
- the speed signal N and the speed signal V arrive via a filter 20 or a filter means 21 for a V / N calculation 22.
- the V / N calculation 22 is again applied logic 23 with a signal. This logic 23 will be too the other signals that the parameter control 16 processed, forwarded. Based on these signals the logic 23 for the output signals of the parameter controller 16 Available.
- the driver request signal MEW is filtered by means of a guide former 13.
- this leadership form is designed as a so-called lead-lag 1st order (PDT1).
- PDT1 lead-lag 1st order
- Such a lead lag element has the following transfer function G13 (s).
- G13 (s) MEF (s)
- MEW (s) (1 + TZF * s) (1 + TNF * s)
- the speed signal N is fed to a fault controller 14, which is preferably a D2T2 element or another phase-correcting transmission element or a suitable bandpass filter.
- This fault controller implemented as a D2T2 element, has the transmission behavior specified in the following formula.
- the fault controller 14 and the guide former 13 are functionally independent of each other. This means that the Parameters TZF, TNF, TDS and KDS both of these Transmission elements can be set independently of one another.
- the parameter control depending on the recognized state of the internal combustion engine corresponding parameter sets and the leadership form or the fault controller with the corresponding parameters applied.
- An external quantity intervention exists, for example, if a transmission control, not shown, a quantity request pretends. In these cases, other parameter sets selected.
- the state is preferably disengaged by means of a Clutch switch 18 detected.
- Clutch switch 18 different voltage values.
- the frictional connection between the engine and Gearbox is interrupted, the switch takes a first one Position on and at its exit there is a first Voltage value.
- Engaged in the state the frictional connection is established between the engine and transmission, the Switch a second position and is at its output a second voltage value.
- the speed and speed signals are evaluated.
- the two signals are each provided with a filter 20 and 21, which preferably have PT1 behavior, are filtered.
- the V / N calculation 22 then calculates the ratio between the driving speed of the vehicle and the speed of the Internal combustion engine. If a gear is engaged, the result is for V / N a value characterizing the engaged gear.
- the idle state is detected, for example, when a Idle controller provides a corresponding signal.
- the idle state can also be evaluated by others Signals are recognized.
- the state “idle” For improved detection of the various states, in particular the state “idle”, the state “Disengaged” and the status “engaged” can be more Sizes are used. This is the driving speed V, the engine speed N, the amount of fuel QK, and the time derivatives, that is, the changes, the sizes.
- a simplified embodiment results if for Lead formers only engaged between the state and the state disengaged is differentiated, whereby in engaged state two parameter sets can be specified.
- a parameter set and is used for the first gear another parameter set selected for the further gears.
- a particularly advantageous embodiment results if different parameter sets for acceleration and for Decelerating the internal combustion engine can be selected. That is, that depending on the sign of the derivative of the speed and / or a power-determining signal different Parameter sets can be selected.
- FIG of a flow chart clarified The procedure according to the invention is illustrated in FIG of a flow chart clarified.
- a first step become the lead former and the fault controller initialized depending on condition. That means an initialization occurs only when certain conditions are recognized.
- a step 220 the status is identified is present. Based on the gear recognition V / N, a signal, that indicates whether the idle controller is active, a signal KS, that indicates whether the clutch is engaged or not and possibly further signals and their derivatives the state of the internal combustion engine is recognized.
- the selected gear is based on the vehicle speed V and the speed N of the internal combustion engine are recognized.
- the Ratio V / N is a measure of the gear engaged.
- the corresponding Parameters for the guide former and the fault controller determined depending on the detected state.
- the Parameters are determined and stored in a memory. Out You can then use this memory depending on the detected state can be read out in step 230. On the one hand, it can be provided be that all types of an internal combustion engine are the same Receive parameter sets. But it is also conceivable that vehicle-specific parameter sets can be saved.
- the subsequent query 240 checks whether a State transition from the "disengaged” state to the state "engaged” KE took place. If not, so be it in step 260 immediately the new parameters that correspond to the new State are used. Detects query 240 against the fact that a state transition from the "disengaged” state KA to the state "engaged” KE was carried out, so check the Query 250 whether the sign of the output signal MES of the Fault controller changed since the last program run Has. If this is not the case, step 265 continues the old parameter set is used. In the event of a change of state from the "disengaged" state to the "engaged” state only uses the new parameter sets if at the same time changes the sign of the MES signal.
- Steps 260 and 265 are followed by another Program run beginning with step 220.
