Tool Released for Fuel Consumption Calculation of Medium & Heavy Duty Vehicles

Government agencies worldwide are currently evaluating options to address the issue of CO2 reduction in the road freight sector. Due to the very large number of vehicle applications, some of them being “one of a kind”, numerous studies, such as the National Academy of Science report, have highlighted the need to use vehicle modeling and simulation for evaluating fuel consumption and CO2 from Medium and Heavy Duty Vehicles.

Argonne has partnered with numerous companies to develop and validate models for medium and heavy duty vehicle applications as well as evaluate fuel consumption potential of both component and powertrain configurations. One of the specificities of Autonomie is its ability to model numerous types of powertrain configurations from conventional to HEVs, PHEVs and EVs, which makes it very suitable to handle the numerous MHDVs options.

Requirements to assess fuel consumption for declaration or labeling purposes are different than the ones for development. As a result, the European Automobile Manufacturers Association (ACEA) has been leading a project to define processes to properly evaluate medium and heavy vehicle’s fuel consumption, from data collection to vehicle modeling and simulation.

Based on a set of requirements provided by ACEA, Argonne has developed a specific version of Autonomie for declaration of fuel consumption with the focus to properly evaluate medium and heavy duty vehicles. This includes the vehicle specification, its specific missions and its performance under relevant operational conditions.

The tool, which can be downloaded at no cost, offers a proven methodology, consistent with OEMs processes, to achieve accurate fuel consumption values.

Please note that this tool contains only a few examples provided for demonstration purposes and as the tool is currently developed under Matlab/Simulink this separate software needs to be installed on the PC. A final version of the tool could be provided as an executable.

For technical questions on the tool, please contact Aymeric Rousseau.

For additional information on the ACEA project, please contact Stefan Larsson.

To download the heavy duty labeling tool, fill in the information below. A license key and download link will be sent to you via e-mail. You should add autonomie-support@anl.gov to your safe sender list. If you do not receive said email from autonomie-support@anl.gov within the next 10 minutes, check your email junk folder, and then contact autonomie-help@anl.gov. Once you receive the email, run the installation and enter the license key at the appropriate step in the process. If you experience any problems during installation, please contact autonomie-help@anl.gov.

Matlab/Simulink and StateFlow are required to run the heavy duty labeling tool.
MathWorks versions between R2007b and R2011a are supported. (64-bit Matlab users, click here.)
