METHOD AND DEVICE FOR DETERMINING AN ENERGY CONSUMPTION WHEN DRIVING A VEHICLE

摘要

The present invention relates to a method for determining a measure of energy utilisation during operation of a vehicle (100) which is provided with a first power source (101) for generating a first motive force for propulsion of said vehicle (100) in a first direction of travel, and with at least one first brake system which can be activated to apply a first brake force which acts against the movement of said vehicle (100) in said first direction of travel. For a first period of time when demand for motive force from said first power source is interrupted the method comprises - estimating energy consumption during operation of said vehicle (100) without demanding brake force from said first brake system, and - using said estimated energy consumption during operation of said vehicle (100), without demanding brake force from said first brake system, as a basis for determining a measure of energy utilisation during operation of said vehicle (100).
