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.
