Resize Engines and Mapped Motors

Use the Virtual Vehicle Composer app to:

  • Resize an engine based on desired maximum engine power or engine displacement.

  • Resize a motor based on high-level specifications.

You can use the dynamometer reference applications to resize engines and motors. For more information, see:

Resize Engine

For virtual vehicles configured with a conventional or hybrid electric vehicle (HEV) powertrain architecture, you can resize the engine based on a desired maximum engine power or engine displacement.

Resizing the engine requires Stateflow®.

After you set up your virtual vehicle, in the Virtual Vehicle Composer app, follow these steps.

  1. In the Virtual Vehicle pane, select Engine, then click the Data and Calibration tab.

  2. Specify a Resize Option option:

    • Power — Enter a Desired maximum power

    • Displacement — Enter a Desired displacement

    For either power or displacement, set the Desired number of cylinders.

    Depending on your Engine, the resize options may enable additional architecture and performance parameters.

  3. Select Resize Engine. The Virtual Vehicle Composer resizes the engine and adjusts the calibration parameters. The Performance pane provides the updated engine performance characteristics based on the resized engine.

Resize Mapped Motor

For virtual vehicles configured with an electric vehicle (EV) or HEV powertrain architecture, you can resize the mapped motor based on a desired maximum motor power.

After you setup your virtual vehicle, in the Virtual Vehicle Composer app, follow these steps.

  1. In the Virtual Vehicle pane, select Electric Machine (Motor), then click the Data and Calibration tab.

  2. Specify the Motor Resize motor parameter options, including desired power, and desired torque.

  3. Select Resize Motor. The Virtual Vehicle Composer resizes the mapped motor. The Performance pane provides the updated performance characteristics and plots based on the resized motor. If you do not resize the motor, the pane provides the performance characteristics and plots of the existing motor.
