Title: Modeling Light Duty Vehicle Emissions Exploiting VT-CPFM Fuel Estimates
Accession Number: 01589744
Record Type: Component
Abstract: The Virginia Tech Comprehensive Power-based Fuel consumption Model (VT-CPFM) is a power-based model that overcomes the limitations of state-of-the-practice models, namely: they produce a bang-bang control system and cannot be calibrated using publicly available data. This paper extends the VT-CPFM model to estimate vehicle emissions of hydrocarbons (HC), carbon monoxide (CO), carbon dioxide (CO₂) and oxides of nitrogen (NOₓ) using the estimated fuel consumption level as the sole explanatory variable. The quality of fit for the HC and CO was good with a coefficient of determination exceeding 0.89 on average; however the quality of fit for NOₓ emissions was lower with a coefficient of determination of 0.73 on average. The proposed emission model produces slightly lower fits compared to the VT-Micro model, however, with a reduction in the number of parameters from 32 to 3 parameters.
