Hunt, SW and Odhams, AMC and Roebuck, RL and Cebon, D (2011) Parameter measurement for heavy-vehicle fuel consumption modelling. Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 225. pp. 567-589. ISSN 0954-4070Full text not available from this repository.
A mathematical model is developed to predict the energy consumption of a heavy vehicle. It includes the important factors of heavy-vehicle energy consumption, namely engine and drivetrain performances, losses due to accessories, aerodynamic drag, rolling resistance, road gradients, and driver behaviour. Novel low-cost testing methods were developed to determine engine and drivetrain characteristics. A simple drive cycle was used to validate the model. The model is able to predict the fuel use for a 371 tractor-semitrailer vehicle over a 4 km drive cycle within 1 per cent. This paper demonstrates that accurate and reliable vehicle benchmarking and model parameter measurement can be achieved without expensive equipment overheads, e.g. engine and chassis dynamometers.
