As EPA’s Office of Transportation and Air Quality develops its programs to control greenhouse gas (GHG) emissions from light-duty highway vehicles, there is a need to evaluate the effectiveness of technologies likely to be used to meet these standards. The Advanced Light-Duty Powertrain and Hybrid Analysis (ALPHA) was created by EPA as an analysis tool to estimate the Greenhouse Gas (GHG) emissions from Light-Duty (LD) vehicle sources. It is a physics-based, forward-looking, full vehicle simulator, which is capable of simulating various vehicle types and powertrain technologies. The ALPHA model uses the industry standard MathWorks software products MatLab, Simulink, and Stateflow version 2014a. The entire model and all subsystems are unlocked for complete transparency and is scheduled to be released to the public in 2016 along with the release of the 2017-2025 light-duty Technical Assessment Report (TAR). Conducting a comprehensive peer review of the model is an important step in gaining wide acceptance of this model by the light-duty automotive vehicle community. This report details the peer review of the ALPHA Full Vehicle Simulation Model dated May 5th, 2016. A number of independent subject matter experts were identified and the process managed to provide reviews and comments on the methodologies used in the model. This peer review process was carried out under EPA’s peer review guidelines1. |
