Get Started with the Virtual Vehicle Composer

The Virtual Vehicle Composer app enables you to configure and build a virtual vehicle that you can use for system-level performance analysis, including component sizing, fuel economy, drive cycle tracking, software integration testing, and hardware-in-the-loop (HIL) testing. Use the app to quickly enter your vehicle parameter data, build a virtual vehicle model, run test scenarios, and analyze the results.

The virtual vehicle model contains the blocks and reference application subsystems available with Powertrain Blockset™ and Vehicle Dynamics Blockset™. You can use the app to quickly configure the architecture and enter parameter data.

Open the Virtual Vehicle Composer App

To open the app, do either of the following:

MATLAB^® Toolstrip: On the Apps tab, under Automotive, click the Virtual Vehicle Composer app icon .
MATLAB command prompt: Enter virtualVehicleComposer.

Virtual Vehicle Composer Workflow

To build, operate, and analyze your virtual vehicle, use the Virtual Vehicle Composer app Composer tab options to follow these workflow steps. To get started with an example, follow the workflow steps to build a four-wheeled electric vehicle (EV), test it with FTP–75 drive cycle, and analyze the results.

Step			Description
1	Configure Virtual Vehicle Data	Vehicle Data	Specify the vehicle architecture, dynamics model, chassis, powertrain, and driver. For each selection, enter the vehicle parameter data.
2	Configure Virtual Vehicle Scenario and Test	Vehicle Scenario and Test	Select the virtual vehicle test scenario. Options include a drive cycle scenario for fuel economy and energy management analysis.
3	Configure Virtual Vehicle Data Logging	Data Logging Editor	Select the model signal data to log when operating your virtual vehicle. Options include vehicle position, velocity, and acceleration.
4	Build Virtual Vehicle	Virtual Vehicle	Build your virtual vehicle. When you build, the Virtual Vehicle Composer creates a Simulink^® model that contains the vehicle architecture and data that you specified in the configuration steps.
5	Operate Virtual Vehicle	Run Test Plan	Simulate your model in the scenario that you specified in step 2.
6	Analyze Virtual Vehicle	Simulation Data Inspector	Use the Simulation Data Inspector to view and inspect the simulation signals.
