Method for estimating the mass of a vehicle which is being driven on a road with varying gradient, comprising the following method steps:

measurement of the vehicle's speed for generating input data for a calculation device;
measurement of a variable which comprises a longitudinal force acting on the vehicle for generating input data for a calculation device;
characterized in that
said calculation device generates an estimate of the weight of the vehicle by means of a recursive process by using a statistical filter using said input data comprising the speed of the vehicle and said variable and a statistical representation of a road with varying gradient.
