Method and device for effecting a computer-aided estimation of the mass of a vehicle, particularly of a goods-carrying vehicle

A method for effecting a computer-aided estimation of a mass of a vehicle, comprising:

• computer-aided differentiating an equilibrium relationship, between a motive force and a sum of an inertial force and drive resistances, in which the mass and a gradient angle of a roadway are included as quantities, with respect to time, assuming a constant gradient angle;
• and
• calculating at least one of (a) the mass of the vehicle and (b) a reciprocal value of the mass of the vehicle from the equilibrium relationship differentiated with respect to time in the differentiating step.

A device for effecting a computer-aided estimation of a mass of a vehicle, comprising:

• a calculation unit adapted to calculate at least one of (a) the mass of the vehicle and (b) a reciprocal value of the mass of the vehicle from an equilibrium relationship between a motive force and a sum of an inertial force and drive resistances, the mass and a gradient angle of a roadway included as calculation quantities, after a computer-aided differentiation of the equilibrium relationship with respect to time, assuming a constant gradient angle.
