Embodiment Construction

[0038] figure 1 A flow chart of a method for adjusting charging parameters according to an embodiment of the present invention is shown. Charging parameters can be adapted to generate the required charging. The required charge can be provided for the drive, for example to drive injection valves or injectors.

[0039] In a first step 102, current charging parameters are provided. In this case, the first current charging parameter can be selected such that it is not yet suitable for generating the required charging.

[0040] In a further step 104 it is checked whether the charge producible from the current charging parameters satisfies predetermined conditions. Here, the predetermined condition can be expressed in any manner suitable for carrying out the method. A predetermined condition can be fulfilled, for example, if the charge that can be generated or the effect that can be triggered by the charge that can be generated satisfies a predetermined criterion. The predeterm...

Abstract

The present invention relates to a method for adjusting a load parameter and a device thereof. A method for adjusting a load parameter suitable for producing a required load, includes a step (102) for producing a current load parameter, a step (104) for testing whether the load produced by the current load parameter satisfies a predetermined condition, and a step (106) for providing a verified load parameter as the current load parameter, until the current load parameter can product a load to be satisfied the predetermined condition.

Description

technical field [0001] The invention relates to a method for adjusting charging parameters according to the preamble of claim 1 , a device for carrying out the method, a computer program and a computer program product. Background technique [0002] Fuel metering is controlled in internal combustion engines by means of injection valves or injectors. Control device injection output stage concepts for Common Rail injectors with magnetic coils or magnetic actuators can be based on boost concepts with DC / DC converters. The purpose of the boost concept is to achieve a steep drive current (Ansteuerstrom) with a drive voltage above the battery voltage in order to drive quickly through the toleranced hydraulics of the injector when opening and closing the nozzle needle of the injector and to Keep its influence on the injection quantity and the injection characteristic curve minimal. A booster capacitor (Booster-Kondensator) can be used to provide the driving voltage. [0003] Comm...
