主　　题：Consumption Power estimates 

摘      要：A power-based vehicle fuel consumption model,entitled the Virginia Tech Comprehensive Power-based Fuel Consumption Model(VT-CPFM)that was developed in an earlier publication is validated against in-field fuel consumption *** study demonstrates that the VT-CPFMs calibrated using the EPA city and highway fuel economy ratings generally provide reliable fuel consumption estimates with a coefficient of determination in the range of *** importantly,both estimates and measurements produce very similar behavioral changes depending on engine load *** VT-CPFMs are demonstrated to be easily calibrated using publically available data without the need to gather in-field instantaneous data.
