Abstract: A system for monitoring the state of a wheel of a rail vehicle includes an acquisition unit that is designed, upon a braking event, to acquire at least one operating parameter for the wheel, an evaluation unit that is designed to determine a temperature value for the wheel based on the acquired operating parameter; and a control unit that is designed to generate and to output an output on the basis of the determined temperature value. It furthermore relates to a method for monitoring the state of a wheel of a rail vehicle, in which, upon a braking event, at least one operating parameter for the wheel is acquired, a temperature value for the wheel is determined based on the acquired operating parameter and an output is generated and output on the basis of the determined temperature value.

Abstract: A method for determining a braking distance of a vehicle, wherein a coefficient of friction (COF)actual between a brake lining and a brake disc is calculated as a function of a tensioning force Fd, a vehicle velocity V and a temperature of the frictional layer Tdisc, wherein the temperature of the frictional layer Tdisc is updated dynamically on the basis of the coefficient of friction COFactual in order to calculate a braking distance which approaches reality.
