Abstract
The method for determining the mass of a vehicle comprises at least two measurements ( ) offset in time within a measuring period by which are determined respectively at least one traction variable ( ) and at least one movement variable ( ) of the vehicle, one of the two measurements ( ) being effected during a traction-free phase and the other of the two measurements ( ) during a traction phase. According to the invention, it is proposed that each of the two measurements comprises one data collection period ( ) 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.
