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™, Vehicle Dynamics Blockset™, Simscape™ Driveline™, and Simscape Electrical™. 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 Virtual Vehicle Composer 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.
