EESA Success Stories
Plug and Play with Autonomie
To reduce cost and time to production of advanced vehicles, car manufacturers are turning to model-based design using computer software instead of building new car prototypes and testing their functionality in real time. Argonne’s PSAT (Powertrain System Analysis Toolkit), a vehicle simulation tool sponsored by
the U.S. Department of Energy, was the precursor to Autonomie. Autonomie expands on PSAT’s capabilities with its totally new code, a hierarchal structure that allows reuse of models, the ability to run single engine and battery systems, and the ability to perform all vehicle model processes in a single software program.
The Challenge
To virtually simulate vehicle powertrains and components and their operation without the expense of building a real-time system.
Argonne researchers Phil Sharer (front) and Aymeric Rousseau work on Autonomie.
The Solution
Argonne has developed Autonomie, a plug-and-play software modeling tool that allows car designers and researchers to integrate old models, controls, data and processes into a single environment that can be used throughout the different steps of the vehicle development process: from model-in-the-loop, software-in-the-loop, hardware-in-the-loop, to rapid control prototyping and production. Reusing models with varying degrees of fidelity and languages will allow engineers to quickly evaluate the benefits of new technologies in a total system context.
The Results
Autonomie:
- Makes it easier and more economical for component suppliers and auto makers to work together
- Reduces time and cost to develop advanced vehicles
- Establishes industry-wide standard interfaces
- Delivers designs that meet FEED requirements (fuel economy, emissions and driveability)
- Provides common methods and tools for comparing and evaluating technologies
"With Autonomie, car manufacturers can easily integrate the supplier’s component model into the manufacturer’s library of models and processes for immediate use," said Autonomie developer Aymeric Rousseau.
