Validation of a Parametric Vehicle Modelling Tool Using Published Data for Prototype and Production Vehicles with Advanced Powertrain Technologies

PAMVEC is a novel vehicle modeling tool designed to complement the capabilities of dynamic vehicle simulators and be better-suited to the purposes of vehicle technology assessment. This paper presents a validation of PAMVEC against published data for a range of production and pre-production prototype vehicles whose powertrain technologies span the range currently being exhibited by automotive manufacturers. For each vehicle, the PAMVEC model was used to predict the fuel/energy consumption and required peak powertrain output due to acceleration performance. Errors typically <10% were observed in the validation results and were considered to be within the bounds of uncertainty in the input data. Despite the difficulty in obtaining some of the input data, PAMVEC was a convenient tool for the energy consumption and performance predictions included in this analysis.
