A method for determining an extra-fuel consumption of a terrestrial vehicle, in particular an industrial or commercial vehicle, comprising (Step 2) estimating a first expected fuel consumption in time, based on said first, second and third set of input parameters, (Step 3) a second acquisition of a measured fuel consumption in time, (Step 4) obtaining an error value in time, (Step 5) and when said error value increases abruptly (5=yes), then (Step 6) activating a flag indicating a condition of extra-fuel consumption, (Step 2') estimating a second expected fuel consumption in time, based on ideal parameter values of use of the vehicle and if there is an offset greater than a predetermined threshold, then a cause of extra-consumption is identified as an incorrect vehicle driving style.
