METHOD AND DEVICE FOR DETERMINING AN ENERGY CONSUMPTION WHEN DRIVING A VEHICLE
First Claim
1. A method for determining a measure of energy utilisation during operation of a vehicle, wherein said vehicle includes a first power source for generating a first motive force for propulsion of said vehicle in a first direction of travel, and at least one first brake system configured to be activated to apply a first brake force which acts against movement of said vehicle in said first direction of travel;
- for a first period of time during said operation of said vehicle and when demand for motive force from said first power source is interrupted, the method comprisesestimating energy consumption during operation of said vehicle without demanding brake force from said first brake system, andusing said estimated energy consumption during said operation of said vehicle, without demanding said brake force from said first brake system, as a basis for determining and determining a measure of energy utilisation during said operation of said vehicle.

Abstract
A method for determining a measure of energy utilisation during operation of a vehicle (100) which has a first power source (101) for generating a first motive force for propulsion of the vehicle (100) in a first direction of travel, and has at least one first brake system which acts against movement of the vehicle (100) in the first direction of travel. For a first period of time when demand for motive force from the first power source is interrupted, estimating energy consumption during operation of the vehicle (100) without demanding brake force from the first brake system, and using the estimated energy consumption during operation of the vehicle (100), without demanding brake force from the first brake system, as a basis for determining a measure of energy utilisation during operation of the vehicle (100).

25. A system for determining a measure of energy utilisation during operation of a vehicle, wherein said vehicle comprises:
-
a first power source for generating a first motive force for propulsion of said vehicle in a first direction of travel;
at least one first brake system which is configured and operable to be activated to apply a first brake force which acts against movement of said vehicle in said first direction of travel;for a first period of time when demand for motive force from said first power source is interrupted, said system comprises; means configured for estimating energy consumption during operation of said vehicle without demanding brake force from said first brake system; and means configured to using said estimated energy consumption during operation, without demanding brake force from said first brake system, as a basis for determining a measure of energy utilisation during operation of said vehicle. - View Dependent Claims (26)
