Virtual Vehicle Composer, vehicle motion, and driving scenarios

The Powertrain Blockset™ includes blocks for 1DOF and 3DOF vehicle motion. The driving scenario blocks allow you to specify a drive cycle and driver commands. Use the vehicle blocks in fuel economy studies and drive cycle analysis.

Use theVirtual Vehicle Composer应用程序配置和构建一个虚拟车辆you can use for system-level performance analysis, including component sizing, fuel economy, and drive cycle tracking. To get started with your virtual vehicle, seeGet Started with the Virtual Vehicle Composer.

Featured Examples

Conventional Vehicle Reference Application

Simulate a full vehicle model with an internal combustion engine, transmission, and associated powertrain control algorithms. Use for powertrain matching analysis and component selection, control and diagnostic algorithm design, and hardware-in-the-loop (HIL) testing.
