This page provides the steps on how to model a parallel hybrid vehicle, it has been documented in such a way that first time user can recreate the simulation from the beginning.
The reference result of this particular vehicle has been uploaded so that the user can compare their own simulation.
To learn more about how to create a simple model, go to ADVANCE Tutorial
All the component modules which are going to be used in this example can be downloaded from SIMarchitect Library.
The model is split into four different areas. Those are:
To create the ECU subsystem:
The components of parallel hybrid vehicle powertrain are:
To create the Plant_model subsystem:
To create driver subsystem:
