Embodiment Construction

[0057] In the following, an embodiment relating to an internal combustion engine 1 is explained. However, it is obvious to the expert that the theory described can also be transferred to other machines, in particular drives such as electric motors.

[0058] figure 1 An embodiment of a method 100 for calibrating a controller of a machine 1 is shown.

[0059] The workflow including the method 100 for calibrating a controller is preferably as follows:

[0060] First of all, the tests or experiments to be carried out, especially the commissioning, are defined. It is preferably determined which input parameters are to be adjusted or changed and which output parameters should be recorded. Determine in what ambient conditions the test should be carried out, eg at what temperature of the cooling medium. It is likewise preferred to determine which output parameters must be monitored relating to the operating limit Lim and where the limit value Lim is. Taking this as a starting poi...

Abstract

The invention relates to a method for analyzing the operation of a machine and / or for calibrating a control unit of a machine, in particular of an internal combustion engine, in which test points defined by the values of a number of predetermined operating parameters and selected by a statistical test design from a multi-dimensional test space are approached, wherein at least one operating parameter is changed in each case in a number of steps from one test point (Tn) to the next test point (Tn + 1) when the test point is approached, and wherein operating measurements (meas) are carried out at a measurement point (Mn) produced by a respective stride and at the original test point (Tn, Tn + 1), wherein measurement data from operational measurements are output and continuously stored for evaluation and calibration of the controller, and to a corresponding system.

Description

technical field [0001] The invention relates to a method for calibrating a controller of a machine, in particular of an internal combustion engine, in which tests are approached which are defined by numerical values ​​of a number of predetermined operating parameters and are selected from a multidimensional test space by means of a statistical test design point, wherein at least one operating parameter is changed in each of a number of steps as the test point is approached. Background technique [0002] For calibrating machines, in particular drives, tests are usually carried out on test benches, wherein analyses for different operating parameters, in particular sensitivity analyses, are carried out for defined approach points with predetermined rotational speeds and / or loads. The knowledge gained from this analysis can be used to calibrate the controller of the internal combustion engine, wherein the purpose is to optimally calibrate the internal combustion engine.
