Parameters Step

The Parameters section contains the following tabs:

Parameters tab
System Constants tab

Parameters Tab

You can define additional parametersets beside Working and Reference. Iterations of the optimizer are automatically stored as separate parametersets. This allows to analyze the optimization progress and also go back to a previous set. See also Parametersets

The Parameters tab (see also Available Types of Parameters) contains the following elements:

Parameterset

List of all available parametersets, including the conversion parameterset that cannot be optimized.

Parameterset context menu (right-click)

Set as Working Parameterset: Sets selected parameterset as working parameterset.

Set as Reference Parameterset: Sets selected parameterset as reference parameterset.

Compare selected Parametersets: Opens the Closed Compare Parametersets window. It shows the maximum difference per parameter and the number of changed and unchanged parameters.

Copy selected Parameterset to:

<Parameterset Name> (Working): Copies the parameters of the selected parametersets to the working parameterset.
<Parameterset Name> (Reference): Copies the parameters of the selected parametersets to the reference parameterset.
Conversion Parameters: Copies the parameters of the selected parametersets to the conversion parameters.

Recalculate

If you click Recalculate directly, the RMSE is calculated for the selected parametersets.

The button opens a Closed drop-down menu.

Set as Working

Sets selected parameterset as working parameterset.

Set as Reference

Sets selected parameterset as reference parameterset.

Set as Conversion

Sets selected parameterset as conversion parameterset.

Duplicate

Creates a copy of selected parametersets and opens a naming dialogue.

New

See also Parametersets.

Import

If you click Import directly, the parameters and their values are imported from a file.

The button opens a Closed drop-down menu.

Parameters	Imports parameters and their values From File or From Open Projects. See Import Parameters .
Bounds	Imports the bounds of scalar, curve, and map parameters From File or From Open Projects. See Import Bounds.
Parameters and Bounds	Imports parameters, their values and bounds (for scalar, curve, and map parameters) From File or From Open Projects. See Import Parameters and Bounds.
from A2L-File	Import limits (Lower Limit and Upper Limit column) and quantization (COMPU_METHOD) from an A2L file for the parameter(s) of the project via name matching. This file can then be used for quantization of parameters. ASCMO-MOCA still handles the parameters as continuous during optimization, but the quantization can be applied afterwards manually e.g., before export.

Note
Available formats are e.g. DCM files (.dcm), several comma-separated value formats (.csv), Excel formats (.xls, .xlsx, .xlsm), calibration data files (.cdfx) or ASCMO projects (*.ascmo).

Export

Click Export to open the Export Parameters window, where you can specify the location, name, and file type for the parameters to be exported.

To select only certain parameters for export, use the checkboxes in the Export column of the Parameters table.

The button opens a Closed drop-down menu.

Parameters (default)	Opens an open file dialog, where you can specify the location, name, and file type for the parameters to be exported.
Bounds	Exports the bounds of map, curve and cube-3D/cube-4D parameters to a file.
Parameters and Bounds	Exports all parameters, their values and bounds (only map, curve and cube-3D/cube-4D parameters) to a file.
Patch Parameter or Variant in Existing DCM File	Exports the selected parameters or variants and patches them into an existing DCM file. This way only the changed parameters can be exported and added to the existing file.
Selected Parameters to Bosch iLrn (offline)	Exports the selected parameters, curves, maps and cubes as BIN and DCM file as iLrn (offline) flatbuffer for Bosch ECUs.
Compressed Model to M-script	Exports parameters of type Compressed Model to an M script file so that the model can be executed in MATLAB®.
Compressed Model to Bosch AMU	Exports parameters of type Compressed Model to a DCM/CDFX file for Bosch AMU.
Parameter list as LAB	Exports parameter names to a LAB file for easy selection in ETAS INCA.

Note
Available export formats are DCM Files (.dcm), several comma-separated value formats (.csv), several Excel formats (.xls, .xlsx,.xlsm), calibration data files (.cdfx), M-scripts (.m), and LAB files (.lab).

In addition to the parameter names and types, the table contains the Closed following columns.

Optimize

To include the parameter in the optimization, activate the checkbox.

Smoothness

The smoothing factor, a real number ≥ 0. If one value is given, the factor applies to all directions. If a vector is given, each element corresponds to one input direction.

Note
Smoothing only supports map, curve, and cube parameters.

Lower Limit

Define the lower and upper limit of the parameter values.

Upper Limit

Grid Reduction Factor

Allows you to reduce complexity for faster optimization.

Export

Allows you to deselect the parameters you don't want to export with Export Parameters. If you select a parameter with a corresponding group axis, the axis is always exported as well.

Parameter value table

Shows the values of the selected parameter. For curves/maps/cubes, the axes are displayed as the column/row headers of the table. The first axis (x) is displayed as the column header. The second axis (y) is displayed as the row header. The cells display the parameter values.

The appearance of the table depends on the parameter type. For 3D and 4D cube parameters, the third and fourth axes are displayed as separate lists. For parameters of compressed model types, the inputs are displayed in a separate list.

Use F2 or Double-click a cell to edit the value.

You can use the standard Ctrl/Shift selection functions in the table, or click and hold Lmb and drag the cursor over the cells/rows you want to select.

Differences between the reference and working parametersets are visually distinguished in the table using different shades of red and blue. Cells appear redder when the reference value is lower and bluer when it is higher, with the darkness of the color reflecting the extent of the difference.

Use the Difference Heatmap checkbox in the Show area to activate/deactivate the color coding.

When the Reference option of the Show area is activated, the table shows the differences between the reference and working parametersets.

To open the Closed context menu of the selected parameter value, right-click in the selection.
