Information

This is a model of a standard driveline.

Instant Plotting

To check the instant fuel consumption and the measured speed, click the Simulate button:

Generate Simulation Scenarios

In Mathematica, use an interactive Manipulate to create simulation scenarios that can be exported to System Modeler.

Manipulate

In the Manipulate, the speeds at which gears are switched can be changed.

In order to get the full experience of this example, you need a desktop Wolfram Language product. A free trial download is available at www.wolfram.com/mathematica/trial/

For the full example, open the accompanying notebook Driveline.nb .
