Abstract

The invention relates to a method and a device for monitoring and influencing the thermal state of a friction brake system of a rail vehicle on the basis of a calculated or estimated predictive friction element temperature (Tpred) of at least one friction element (1, 2) of the friction brake system. The method has at least the following steps: detecting at least one parameter which characterizes the current driving operation situation of the rail vehicle; calculating, estimating, or determining a first temperature component (TCUrrent) of the predictive friction element temperature (Tpred) on the basis of the current driving operation situation of the rail vehicle; and taking into consideration a first temperature component (Tcurrent) while monitoring and influencing the thermal state of the friction brake system. According to the invention, while monitoring and influencing the thermal state of the friction brake system, a second temperature component (dT) of the predictive friction element temperature (Tpred) is additionally taking into consideration which would be set on the at least one friction element (1, 2) in addition to the first temperature component (Tcurrent) with the assumption that a braking process with a defined braking mode is being carried out virtually or theoretically in the current driving operation situation of the rail vehicle, and the predictive friction element temperature (Tpred) of the at least one friction element (1, 2) is determined as the sum of the first temperature component (Tcurrent) and the second temperature component (dT). If the predictive friction element temperature (Tpred) is greater than the permissible friction element maximum temperature (Tmax) of the at least one friction element (1, 2), a first signal is generated which represents a potentially thermally critical state of the at least one friction element (1, 2), otherwise the first signal is not generated.

Abstract

A brake system, brake regulating method and device for a rail vehicle use an input for a target deceleration value (äset), an input for an actual deceleration value (atrain), and an output for a deceleration control variable value. The deceleration control variable value (aOUt) is set by a regulating unit to minimize a deviation between the actual deceleration value (atrain) and the target deceleration value (aset). The brake regulating device uses a limiting device, which limits the deceleration control variable value (aout) independently of the regulating unit such that the deceleration control variable value (aout) deviates from the target deceleration value (aset) maximally by a maximum negative control stroke to lower values or maximally by a maximum positive control stroke to higher values. The invention additionally relates to a braking method and a brake system for a rail vehicle.
