The invention relates to a method for determining an optimal or maximum permissible speed (vopt) of a rail vehicle as a function of a thermal state of at least one friction element (1, 2) of at least one friction brake of the rail vehicle, comprising at least the following steps: a) detecting at least one parameter characterizing a current driving operating situation of the rail vehicle, b) determining or estimating a first influence on the thermal state of the at least one friction element (1, 2) on the basis of the current driving operating situation of the rail vehicle, according to the invention, the method comprises at least the following further steps: c) determining or estimating a second influence on the thermal state of the at least one friction element (1, 2), the second influence, in addition to the first influence, influences the thermal state of the at least one friction element (1, 2) when braking is carried out virtually or theoretically with the defined braking type in the current driving operating situation of the rail vehicle, d) determining an optimal or maximum permissible speed (vopt) of the rail vehicle as that the maximum permissible speed (vopt) of the rail vehicle is greater than the maximum permissible speed (vopt) of the at least one friction element (1, 2). The at least one friction element (1, 2) is designed such that, on the at least one friction element (1, 2) under the first influence and under the second influence, d1) does not exceed the permissible friction element maximum temperature (Tmax) of the at least one friction element (1, 2), or d2) substantially occurs the permissible friction element maximum temperature (Tmax) of the at least one friction element (1, 2).
本发明涉及一种用于根据轨道车辆的至少一个摩擦制动器的至少一个摩擦元件(1、2)的热状态来确定轨道车辆的最佳或最大允许速度(vopt)的方法,所述方法至少包括以下步骤:a)检测表征轨道车辆的当前行驶运行情况的至少一个参数,b)基于轨道车辆的当前行驶运行情况确定或估计对所述至少一个摩擦元件(1、2)的热状态的第一影响,根据本发明,该方法至少包括以下另外的步骤:c)确定或估计对所述至少一个摩擦元件(1、2)的热状态的第二影响,当在轨道车辆的当前行驶运行情况中以所定义的制动类型虚拟地或理论地执行制动时,所述第二影响附加于第一影响会影响所述至少一个摩擦元件(1、2)的热状态,d)将轨道车辆的最佳或最大允许速度(vopt)确定为,使得在所述至少一个摩擦元件(1、2)上在第一影响下并且在第二影响下d1)不超过所述至少一个摩擦元件(1、2)的允许的摩擦元件最高温度(Tmax),或者d2)基本上出现所述至少一个摩擦元件(1、2)的允许的摩擦元件最高温度(Tmax)。
