Method for determining state in rail vehicle

The invention relates to a method for determining a value of at least one state parameter of a rail vehicle (101) and/or of a travel path of the rail vehicle (101), wherein in at least one detection step, at least one current first detection signal associated with a current value of the state parameter is detected by means of a first signal recorder (106.1, 106.2, 106.3) on a structure in the interior of the rail vehicle (101), the first signal recorder (106.1, 106.2, 106.3) of the mobile terminal (106) being used to detect the current first detection signal. In order to determine the value of the at least one state parameter, the frequency range of the current first detection signal from 1 Hz to 2 Hz, preferably from 4 Hz to 15 KHz, further preferably from 10 Hz to 1 kHz, is evaluated. 本发明涉及一种用于测定轨道车辆(101)的和/或轨道车辆(101)的行驶路径的至少一个状态参数的值的方法，其中在至少一个探测步骤中至少一个与状态参数的当前值关联的当前第一探测信号通过在轨道车辆(101)的内部中的结构上的第一信号记录器(106.1，106.2，106.3)探测，其中为了探测当前第一探测信号，使用移动终端设备(106)的第一信号记录器(106.1，106.2，106.3)。为了测定至少一个状态参数的值，对从1Hz至2Hz、优选从4Hz
