Get Started with the Virtual Vehicle Composer

The Virtual Vehicle Composer app 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 enter your vehicle parameter data, build a virtual 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 architecture and entering 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 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	Setup Virtual Vehicle	Setup	Select New, then specify: Project, folder, and model name Powertrain architecture Model template Vehicle dynamics
2	Configure Virtual Vehicle Data	Data and Calibration	Specify the chassis, tire, brake type, powertrain, and driver. For each selection, enter the vehicle parameter data.
3	Configure Virtual Vehicle Scenario and Test	Scenario and Test	Select the virtual vehicle test scenario. Options include a drive cycle scenario for fuel economy and energy management analysis.
4	Configure Virtual Vehicle Data Logging	Logging	Select the model signal data to log when operating your virtual vehicle. Options include vehicle position, velocity, and acceleration.
5	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.
6	Operate Virtual Vehicle	Run Test Plan	Simulate your model in the scenario that you specified in step 2.
7	Analyze Virtual Vehicle	Simulation Data Inspector	Use the Simulation Data Inspector to view and inspect the simulation signals.
