FTP-75 drive cycle simulation

Use Vehicle1D Performance Design App to design the basic performance parameters of a road vehicle.

Use Motor Drive Unit Efficiency App for System Thermal Model to understand how the model parameters are affecting the motor efficiency.

The BEV model is built in a simple and modular fashion, and it can run faster than real-time. It is suitable as a baseline model for drive cycle simulation to estimate vehicle's electrical efficiency and other vehicle-level information.

This project also contains the model of a detailed permanent magnet synchronous motor and controller. It runs slower than real-time, but it captures the detailed behaviors of the AC motor drive unit and can estimate the electrical efficiency at the unit level.

A Live Script for a detailed motor drive unit demonstrates how to obtain the electrical efficiency from the detailed motor drive unit and use the result as the block parameter of the abstract motor drive block in the BEV model.

Main Live Script for BEV model

This script shows an example workflow to programmatically open model, run simulation, collect simulation data, visualize result, save data to text-format file, read saved data file, and analyze.
