Abstract
A method is for effecting a computer-aided estimation of the mass of a vehicle, e.g., of a goods-carrying vehicle, based on the equilibrium ratio between the driving force and the sum of the inertial force and drive resistances, in which the mass and a gradient angle of the roadway are contained as quantities. The method may include: a) computer-aided differentiation of the equilibrium ratio according to the time with the assumption that the gradient angle is constant; and b) calculating the mass of the vehicle and/or the reciprocal value of the mass from the equilibrium ratio differentiated according the time.

13. 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. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
