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, 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 utilizes sets of blocks and reference application subsystems available with 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 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.
