VEHICLE CHARACTERIZATION AND FUEL CONSUMPTION PREDICTION USING MAPS AND POWER DEMAND MODELS

A sample of 177 currently used Australian light duty vehicles were dynamometer tested and averaged vehicle maps of fuel consumption and emissions are presented. These maps show emission rates and fuel consumption as a function of velocity and acceleration. The use of vehicle maps as a diagnostic tool to characterize vehicle behaviour is also demonstrated. A two-parameter vehicle power demand model is developed which predicts road, or dynamometer, vehicle fuel consumption, and also emission rates for any desired velocity profile. For trips of greater than 10 km the fuel consumption estimates are accurate within 2%, while on shorter trips of less than 1 km the estimates are accurate to within 9%. A power demand model correction matrix is presented which is used to predict fuel consumption for trips of less than 100 m. This matrix adjusts the basic power demand model for vehicle inefficiencies at low speed due to gear and automatic transmission loss. (TRRL)
