Definitions
- the invention relates to a method and a device for controlling an internal combustion engine according to the preambles of the independent claims.
- a method and a device for controlling an internal combustion engine is known from the unpublished DE 102 21 376. There, a method and a device for controlling an internal combustion engine are described, in which a lambda value of the exhaust gas is determined on the basis of operating parameters. This is compared with the actual lambda value and, based on the comparison, a correction value is calculated for correcting a fuel quantity or air quantity signal.
- a sensor is used to determine a first quantity that characterizes the actually injected fuel quantity from the sensor signal of a lambda sensor and an air mass sensor, and is compared with a second quantity that characterizes the desired fuel quantity to be injected. On the basis of this comparison, a first correction value for correcting a fuel quantity and / or a second correction value for correcting an air quantity is specified.
- the amount of fuel actually injected should correspond to the desired amount of fuel. Due to tolerances and / or aging effects, the case occurs that the desired amount of fuel deviates from the amount of fuel actually injected. Now the air quantity metered to the internal combustion engine is controlled and / or regulated depending on the desired fuel quantity to be injected, an incorrect air quantity is set. Control depending on the amount of fuel actually injected is not readily possible since it is difficult to ascertain. By measuring the lambda value of the exhaust gas and the amount of air supplied to the internal combustion engine, the amount of fuel actually injected can be calculated and compared with the desired amount of fuel to be injected. A correction value results from the deviation of these two signals. This correction value can now be used to intervene in the air system.
- the fuel quantity value that is supplied to the air system is corrected with the corresponding correction value. Furthermore, it can be provided that the air quantity is corrected accordingly directly.
- the lambda signals or other variables that characterize the fuel quantity can also be used directly.
- the fuel metering system is directly intervened in such a way that a quantity of fuel quantity is corrected by means of the correction value until the quantity of fuel to be injected and the quantity of fuel actually injected match.
- a direct correction of the fuel quantity is problematic, since such a correction can lead to an increase in the quantity.
- the direct quantity intervention corrects deviations of any size or affects the entire engine operating range.
- the correction value acts on the fuel quantity and / or on the air quantity.
- the correction value which acts on the fuel quantity, is limited to a maximum value. This procedure can have an impact on exhaust emissions as well driving behavior can be compensated.
- the entire error is compensated for by means of a direct intervention. If this is not possible, the remaining error is compensated for by indirect intervention.
- the direct intervention affects the amount of fuel and the indirect intervention affects the amount of air.
- the quantity error which corresponds to the deviation between the actual and the desired fuel quantity, is partially compensated for by a direct intervention in the metering and an adaptation to the air mass to the remaining quantity error.
- the type of intervention takes place depending on the engine operating state. This is achieved, for example, in that the limitation and thus the proportion of the direct intervention is predetermined as a function of operating states and is therefore continuously adjusted.
- the rotational speed and / or a variable characterizing the load of the internal combustion engine are preferably used as the operating parameters.
- the first and / or the second correction value are adapted.
- the correction values are stored in one or more characteristic maps depending on the operating state of the internal combustion engine, or variables are determined and stored which can be used to calculate the correction values in accordance with a mathematical procedure.
- the stored correction values or the stored variables are used.
- the cylinders of the internal combustion engine are divided into at least two groups and that different second correction values are specified for the different groups.
- the remaining and / or the individual errors of the individual groups are compensated for by an indirect intervention.
- the correction is carried out by means of a fuel quantity intervention until a certain error has occurred. In the case of larger and / or asymmetrical errors, a correction is also made using an air volume intervention.
- FIG. 1 shows a block diagram of the device according to the invention
- Figure 3 each has an embodiment for an internal combustion engine, in which the cylinders of the internal combustion engine are divided into at least two groups.
- a fuel quantity control is designated by 100 in FIG.
- a desired fuel quantity MES to be injected.
- This signal relating to the desired quantity of fuel to be injected reaches a fuel quantity actuator 110 via a connection point 105.
- the fuel quantity actuator 110 determines the time and the end and thus the duration of the fuel metering. This is preferably designed as a solenoid valve or as a piezo actuator, which is preferably arranged in an injector, an injection nozzle, or another actuator.
- An air quantity control 200 supplies an air quantity signal MLS based on various input variables, such as the rotational speed N of the internal combustion engine and a quantity MES that characterizes the fuel quantity to be injected.
- the output signal of the quantity control 100 is preferably used as the input variable for the fuel quantity to be injected.
- the output signal MLS of the air quantity controller 200 is applied to an air quantity actuator 210 via a connection point 205.
- the air quantity actuator 210 sets the corresponding air quantity.
- This is preferably an actuator for influencing the recirculated exhaust gas quantity in the form of an exhaust gas recirculation actuator, a throttle valve which influences the air quantity supplied to the internal combustion engine, and / or a supercharger.
- a fuel quantity calculation 120 determines a quantity MEI that characterizes the actually injected fuel quantity, which is also referred to below as the first quantity.
- the fuel quantity calculation processes in particular a signal L which characterizes the oxygen concentration in the exhaust gas and a signal MLI which characterizes the air quantity supplied to the internal combustion engine.
- the two signals are preferably provided by sensors, in particular a lambda probe and an air mass meter. Alternatively, these signals can also be determined on the basis of other variables.
- the first and second variables MES and MEI arrive at a node 125 with different signs.
- the output signal DME of the node indicates the deviation between the quantity of fuel actually injected and the desired quantity of fuel to be injected.
- This signal DME with respect to the injection quantity error reaches an first characteristic diagram 134 via an integrator 130 and a limiter 132.
- the output signal QME of the first characteristic diagram is applied to the second input of the node 105.
- Limiter 132 in turn applies a signal to integrator 130. Both the limiter 132 and the map 134 are different _ (s _
- the signal DME with respect to the injection quantity error passes through a filter 140 and a sign inverter 142 to a second characteristic map 144, the output signal QML of which is applied to the second input of the node 205.
- the second map 144 is also supplied with various signals relating to different operating parameters, such as the speed N, for example.
- the integrator 130 and the limiter 132 act as an integral controller with output size limitation and anti-windup function. This means that the injection quantity error is integrated by the integrator 130.
- the integrator is stopped; this is indicated by the connection between the limiter and the integrator 130.
- the output signal of the limiter remains at the value reached.
- the limiting value of the limiter 132, to which the output signal of the integrator 130 is limited, can be specified according to the invention in one configuration depending on the operating state of the internal combustion engine.
- the limiting value is preferably predetermined as a function of the engine speed N and / or other operating parameters.
- the output signal of the limiter 132 is the quantity error that is to be compensated for by a direct intervention in the fuel quantity.
- This is adapted in the following first map 134. This means that if a certain operating point of the internal combustion engine is reached, which is preferably defined by the speed and the load, the injection quantity errors are determined and integrated and limited on the basis of the comparison between the first and the second variable. The value determined in this way is then stored in the characteristic diagram 134 depending on the operating point.
- the fuel quantity should only be corrected in certain operating ranges. This is ensured by the fact that in the other operating areas in which no fuel quantity correction is to take place Limit value is set to zero.
- the fuel metering and thus the driving behavior are adapted in the other operating points.
- the air quantity is also corrected. That is, either only the amount of fuel is corrected, or only the amount of air, or both amounts are corrected.
- the integrator If the integrator reaches the limit, the injection quantity error is not completely corrected via the fuel metering. Accordingly, the integrator input signal remains non-zero, i.e. the injection quantity error is not equal to zero. This remaining injection quantity error is compensated for by the air quantity.
- the signs of the two interventions differ, this is guaranteed by the inverter 142.
- the dynamics of the air branch can be applied independently of the fuel quantity metering.
- the air quantity branch preferably has a dynamically slower behavior so that the learning of the fuel quantity correction is not unnecessarily influenced.
- the correction values QME for the fuel quantity to be injected and QML for the air quantity are calculated and stored in the maps 134 and 144 depending on the respective operating point, i.e. learned. If the first variable MEI is not available, this is the case, for example, when the lambda signal does not provide reliable values, the values stored in the maps 134 and 144 are used to correct the fuel quantity and / or the air quantity.
- FIG. 1 A further embodiment of the procedure according to the invention is shown in FIG. This procedure is intended in particular for special so-called V-engines, which essentially consist of two in-line engines that have a common crankshaft.
- V-engines which essentially consist of two in-line engines that have a common crankshaft.
- this embodiment is not only limited to such engines, it can generally be used in internal combustion engines in which the cylinders of the internal combustion engine are assigned to different banks / groups, each of the banks / groups being assigned an actuating element for influencing the air quantity.
- the procedure can also be used for a larger number of banks. In particular, the procedure can also be used if an actuator for influencing the amount of air is assigned to each cylinder.
- FIG. 2 Elements already described in FIG. 1 are identified by corresponding reference symbols.
- the embodiment of FIG. 2 essentially differs from FIG. 1 in that two quantity calculations 120 are provided for the fuel quantity actually injected.
- the quantity calculation for the first bank is correspondingly designated as in FIG. 1.
- the quantity calculation for the second bank is designated 320.
- the first size that is assigned to the first bank is referred to below as MEIL and the first size that is assigned to the second bank is called MEIR.
- the node 125 of the first bank corresponds to the node 325 of the second bank.
- the quantity error of the first bank is denoted by DMEL and the quantity error of the second bank by DMER.
- the elements 140, 142, 144 and 205 of the first bank are designated 340, 342, 344 and 305 in the second bank. The functioning of these elements corresponds to the functioning of the corresponding elements in FIG. 1.
- the output signal of a division device 350 which processes the output signal of the link 160, is fed to the integrator 130.
- the injection quantity error of the first bank DMEL and the injection quantity error of the second bank DMER are supplied to the node 160. This means that the integrator is fed the mean value of the two injection quantity errors of the two different banks. It goes without saying that the input signals of the quantity calculation 120 or 320 are provided by different sensors that are assigned to the individual banks. _ Q -
- the procedure of FIG. 1 is essentially transferred to one of the banks, i.e. the individual elements are designed twice.
- the fuel quantity is corrected uniformly for both banks. This is necessary because a different correction would lead to malfunctions with other regulations or controls. If the limit is reached in the fuel quantity correction, the remaining bank-specific residual errors are compensated for via the air volume interventions. The same applies if different injection quantity errors occur for the different banks. In this case, the mean error is compensated for by the intervention in the amount of fuel, and the bank-specific residual errors are also compensated for by the intervention in the amount of air.
- FIG. It essentially corresponds to the functionality of embodiment 2, but requires less computer runtime and less space. Elements already described in FIGS. 2 and 1 are designated by corresponding reference symbols.
- the injection quantity error DMEL of the first bank reaches a connection point 410 and a connection point 420.
- the injection quantity error of the second bank DMER likewise reaches the two connection points 410 and 420.
- connection point 410 the sum of the two signals and in connection point 420 the difference of two signals formed.
- the output signals of node 410 and 420 are divided by two.
- the mean 140 of the two injection quantity errors of the two banks is thus fed to the filter 140.
- the deviation from the mean value is fed to the filter 340.
- the output signal of the characteristic map 144 is applied to a filter 430 on the one hand and to the two node 440 and 450 on the other.
- the filter is preferably designed as a factor element.
- the two connection points 440 and 450 are accordingly acted upon by the output signal of the characteristic diagram 344.
- the output signal of the filter 430 reaches the limiter 132.
- the signal QMLL is present at the output of the node 440 and the signal QMLR at the output of the node 450.
- the mean value and half the difference, ie the deviation from the mean value are the individual errors in the characteristic diagrams 144 or 344 learned.
- the three correction terms QME, QMLL and QMLR are determined from these variables by means of a suitable adaptive combination with a suitable choice of sign. This means that elements 430 and 132 can be specified depending on the operating point.
- the two interventions on the air volume are symmetrical with respect to the mean with the opposite sign.
- the maps 144 and / or 344 can alternatively also be designed as any learning functions.
- a low-pass filter 140 is used instead of an integrator to learn the mean value. For this reason, the quantity error is never fully compensated for by the intervention in the fuel quantity. So there is always an intervention in the amount of air.
- the transmission behavior of the filter 430 like the values of the limits of the limiter 132, can be predetermined depending on the operating state.
- the correction takes place via a uniform intervention on the fuel quantity for all cylinders.
- the correction by means of the intervention on the air volume is carried out individually for different groups of cylinders. It can be provided that the correction takes place for individual cylinders or together for several cylinders.
- the number of correction values preferably corresponds to the number of air mass meters and / or the number of adjusting elements.
