Calibrating the Tables

The lookup tables currently have zero as the entry for each cell. This section demonstrates how to fill the table T with values of torque using the torque model, tq.

To view the Table display, click the T node.

This view has three panes: the table, the graph, and the comparison-of-results pane.

To fill the table with values of the model at the appropriate operating points:

1. Click  on the toolbar.

1. This opens a dialog box that suggests the set points of AFR and SPK as appropriate values for evaluating the model over the range of N and L.

2. Click OK.

1. The following view shows the table filled with values of the model.

   

The following comparison-of-results pane shows just how good a fit the strategy is to the model.

The model is represented by the multicolored surface and the strategy is the blue surface.

The table T is now filled with values of the model at these operating points.

For more information about the process of filling tables, see Calibrating the Tables.

Now you must fill the tables F_A and F_SPK and their normalizers. The tables are modifiers for AFR and the spark angle respectively. These steps are described in the next section.
