Logging
On the Logging tab, select the signals to log. The app has a default set of signals in the Selected Signals list. The default list depends on the vehicle configuration. You can add or remove signals. Options include energy-related quantities, and vehicle position, velocity, and acceleration.
Build
To build your virtual vehicle, on the Composer tab, in the Build section, Click Virtual Vehicle. When you build, the Virtual Vehicle Composer app creates a Simulink model that incorporates the vehicle architecture and parameters that you have specified and associates the model with the test plan you have assembled.
The build takes time to complete. View progress in the progress bar.
Operate
To run your entire test plan, on the Composer tab, in the Operate section, click Run Test Plan .
The simulations take time to complete. View progress in the MATLAB Command Window.
The app can also produce a power analysis report for the last scenario in your test plan. For more detail, see Run Power Accounting.
Analyze
To view and analyze simulation signals you chose to log during operation, on the Composer tab, in the Analyze section, click Simulation Data Inspector.
If your test plan includes more than one test scenario, the Simulation Data Inspector displays the results from the last scenario. To see results from earlier scenarios, load the archived results.
