Title: Method for determining spinning or slipping of the wheels in propulsion vehicles without dead axles

Abstract: A method for determining the spinning or slipping of the wheels in propulsion vehicles without dead axles, particularly railroad vehicles in which: the highest and the lowest wheel velocity of the measured wheel velocities of all axles is determined; the highest wheel velocity is selected in the presence of a braking command, and otherwise, the lowest wheel velocity is selected; a simulated car velocity is determined from the selected wheel velocity taking accelerating or decelerating influence variables into consideration; and the simulated car velocity is compared with the measured wheel velocities and the differences that result are converted into signals for influencing the drive or the braking device of the respective axle.
