Virtual Vehicle Composer
Description
The Virtual Vehicle Composer enables you to quickly configure and build a virtual vehicle that you can use for system-level performance testing and analysis, including component sizing, fuel economy, battery state of charge, drive cycle tracking, vehicle handling maneuvers, software integration testing, and hardware-in-the-loop (HIL) testing. Use the app to configure your virtual vehicle architecture, select and parameterize its components, build the vehicle model, run test scenarios, and analyze the results.
The virtual vehicle model uses sets of blocks and reference application subsystems in Powertrain Blockset™, Vehicle Dynamics Blockset™, and Simscape™ add-ons. Virtual Vehicle Composer simplifies the task of configuring the vehicle and test plan.
If you have Powertrain Blockset, use the app to:
Configure and build a passenger vehicle with a conventional, battery-electric, or hybrid-electric powertrain architecture.
Operate the vehicle in test conditions such as FTP drive cycles.
Analyze design tradeoffs and size components.
If you have Vehicle Dynamics Blockset, use the app to:
Configure and build a passenger vehicle and analyze its handling characteristics by running standard test maneuvers.
Configure and build a motorcycle, and run it in drive cycles or vehicle handling maneuvers. Requires a Simscape license.
Visualize your virtual vehicle in the Unreal Engine® simulation environment. Requires a Simulink® 3D Animation™ license.
If you have Simscape and these Simscape add-ons, you can set Model template to
Simscape to configure vehicles with Simscape subsystems:
Simscape Driveline™
Simscape Electrical™
Simscape Fluids™
Simscape Multibody™ — Required for motorcycles
To build, operate, and analyze your virtual vehicle, use the Composer tab. The options and settings depend on the available products. See Product and Configuration Dependencies for Virtual Vehicle Composer for more detail.

If you want to run your virtual vehicle in the Unreal Engine 3D simulation environment, set 3D Scene Selection to
3D Scene. See the requirements in Unreal Engine Simulation Environment Requirements and Limitations (Vehicle Dynamics Blockset).
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 template that incorporates the vehicle architecture and parameters that you have specified and associates the model with the test plan you have assembled. For more information, see Virtual Vehicle Model Template.
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.
For more detail, see Simulation Data Inspector.
