Abstract

The method for determining the mass of a vehicle comprises at least two measurements (6, 8) offset in time within a measuring period by which are determined respectively at least one traction variable (2) and at least one movement variable (4) of the vehicle, one of the two measurements (8) being effected during a traction-free phase and the other of the two measurements (6) during a traction phase. According to the invention, it is proposed that each of the two measurements comprises one data collection period (6, 8) the duration of which is longer than a minimum duration, that the traction variable corresponds to the timed integral of the traction and the movement variable to the change of speed of the vehicle.
