Prediction of the Fuel Consumption of Heavy Goods Vehicles by Computer Simulation

摘要

The requirement for a computer simulation model of the fuel consumption of Heavy Goods Vehicles is identified and a model is defined. Different operating conditions are simulated and the results compared with those produced by an instrumented articulated vehicle operating at different gross vehicle weights. A comparison is made over short distances and defined conditions on the TRRL test track, and definition of driver behavior enables the experimental situation to be represented. Longer road routes including sections of urban, rural and motorway roads were also simulated and the model accurately predicted the fuel consumption for all gross vehicle weights tested.
