Definitions
- the invention relates to a method and a device for controlling an internal combustion engine according to the preamble of the independent claims.
- the present invention also relates to a computer program product.
- a further method and a further device for controlling a fuel metering system of an internal combustion engine is known from DE 199 45 618.
- This method sets the driving time of at least one electrically operated valve, the fuel quantity to be injected.
- the minimum actuation duration is determined at which fuel is being injected. Respectively. It determines the amount of fuel that is metered at the recognizedan horrdauer.
- This method is also called zero-quantity calibration. The aim of such a zero-quantity calibration is to obtain an accurate metering of small injection quantities, which is particularly important for a
- Pre-injection are metered, perform precisely. This method is carried out during operation, but has the disadvantage that only a certain operating point is considered. Ie. this method only provides a correction value for very small injection quantities. Whereby these correction values for small correction quantities can not easily be transferred to large actuation durations and / or large injection quantities.
- At least a first signal that determines the duration or the end of the injection and / or a second signal that determines the beginning of the injection is corrected with a correction value.
- This correction value is adapted on the basis of at least one information value provided by at least one adjustment method.
- the information values are provided, in particular, by a zero-quantity correction, by a quantity balancing regulation or by another balancing method. It can be provided that both the duration and the beginning of the fuel injection quantity is corrected. In simplified embodiments, in each case only the duration or only the beginning is corrected accordingly. It is particularly advantageous if the duration is corrected accordingly. Also particularly advantageous is an embodiment which stores the first signal and / or the second signal that determine the duration or the start of the fuel injection in a characteristic map and directly adapts these characteristic field values.
- the adaptation can be designed such that the output signals of the respective characteristic field are corrected additively and / or multiplicatively or the
- the information values used usually represent one or more correction values for each one operating point. This is how the information value represents, for example, given by zero-quantity calibration - A -
- the correction value for small injection quantities may characterize the correction value for the same and / or other operating points.
- the information value preferably indicates the deviation of the actually injected fuel quantity from the desired fuel quantity. If such fuel quantity signals are not available, it is also possible to use other signals which use quantities which characterize the quantities of fuel.
- a corresponding signal can be determined on the basis of the rail pressure progression.
- a variable is determined which corresponds to the actually injected fuel quantity. It is particularly advantageous here that this information value can be determined almost at all operating points. This considerably simplifies the evaluation since only an interpolation between stored values and no calculation of values via a correlation is required.
- the correction values of the remaining operating points of the correction map or pump map are now concluded on the basis of this one or more correction values which are provided by an information value. It can be provided that, starting from the information value, all operating points or only a part of the operating points are closed. Thus, it can certainly be provided that the correction values of the zero-quantity calibration are taken into account only up to a certain quantity value. Ie. the information values are used at least for certain map areas.
- the adjustment methods only act on the first and / or second signal via the correction map. This means, for example, if a balancing control is used as the balancing method, then these values are used to adapt the correction characteristic field.
- the adjustment Do not proceed directly to the activation time or the start of the activation. This is possible since corresponding errors and tolerances are already taken into account by the correction according to the invention.
- the adaptation is prevented, ie, for example, the adaptation is inhibited for diagnosis. This is necessary because the adaptation also compensates for deviations and tolerances based on errors. An error detection would thus be difficult.
- the adaptation values can be evaluated for error detection. For example, it may be provided that errors are detected when the adaptation values assume such a large amount.
- the correction takes place in such a way that there is a fixed known association between the first signal and the fuel quantity and between the second signal and the time at which the injection begins. This means that the correction takes place in such a way that with the same drive signal AD or AE the injector always meters the same quantity of fuel at the same time. Regardless of tolerances and signs of aging, the same drive signals can always be used.
