Virtual Vehicle Composer

Configure, build, and analyze a virtual automotive vehicle

Description

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.

If you have Powertrain Blockset, use the app to:

Analyze design tradeoffs and size components.
Configure hybrid-electric vehicle (HEV) architectures.

If you have Vehicle Dynamics Blockset, use the app to:

Analyze ride-and-handling effects of standard test maneuvers.
Visualize your virtual vehicle in the Unreal Engine^® simulation environment.

If you have Simscape Driveline and Simscape Electrical, use the app to configure the vehicle plant and powertrain architecture with Simscape subsystems.

To build, operate, and analyze your virtual vehicle, use the Composer tab. The options and settings depend on the available products.
