Title:

Estimation of Rolling Resistance and Fuel Consumption with a Fully Mechanistic Model

Accession Number:

Record Type:

Component

Abstract:

A novel method for the estimation of rolling resistance and its contribution to fuel consumption is presented. The method employs on-road data from an instrumented heavy-duty truck within computer simulations of a fully mechanistic model of vehicle dynamics. The experimental data set consisted of measurements obtained at the Mainline MnROAD pavement test track near Albertville, Minnesota, and at two highway sections with distressed bituminous and concrete pavements. The instrumented MnROAD heavy-duty truck was driven on the pavement sections while recording signals from the chassis-mounted accelerometers, differential Global Positioning System (GPS), and the Controller Area Network of the truck. Weather data, road elevation, and International Roughness Index (IRI) were also collected during the tests. Experimental data were utilized in the mechanistic model to estimate rolling resistance forces and associated fuel consumption for each of the pavement test cells and the two highway sections. Dynamic rolling resistance and power dissipated by the truck tires and suspensions were computed from the spectral analysis of signals from accelerometers mounted on axles and frame. The spectral analysis revealed vibrational modes unique to either bituminous or concrete pavements. The results demonstrate the ability of the mechanistic model to resolve rolling resistance and its contribution to fuel consumption from on-road vehicle data acquired with a simple experimental setup.
