METHOD OF DETERMINING AN ITINERARY SO THAT THE FUEL CONSUMPTION CAN BE PREDETERMINED ACCORDING TO THE CHARACTERISTICS OF THE ROUTE

摘要

Method for determining a low-fuel-consumption itinerary for a digital road network system stored on a memory support and involving the steps consisting in : identifying a plurality of potential routes Rpot from which an itinerary can be chosen; choosing, from all the potential routes Rpot, the itinerary that represents best value in terms of weighting factors; said method further involving a step that consists in determining the fuel consumption of a road-going vehicle using computation means on the basis of data corresponding to the technical characteristics of the vehicle and physical characteristics of portions of the itinerary so as to obtain, during the step that involves choosing the resulting itinerary, a low-fuel-consumption itinerary that takes account of the corrected fuel consumption of the vehicle: it is thus possible truly to take into consideration the impact of the type of vehicle and also the impact of the type of route in each portion.
