The invention relates to a method and to a device for detecting a derailment state of a rail vehicle, wherein at least one kinematic variable is measured by means of a first sensor (1) with respect to a first wheelset end portion (3) and by means of a second sensor (2) with respect to a second wheelset end portion (4), and corresponding measurement signals are formed, processed and evaluated. According to the invention, values of a first falling velocity (vf1) with respect to the first wheelset end portion (3) and values of a second falling velocity (vf2) with respect to the second wheelset end portion (4) are calculated from the measurement signals by means of at least one computing unit (5), and a derailment state of the rail vehicle is detected by means of a first comparison operation (6) of the first falling velocity (Vf1) and the second falling velocity (vf2) with a first falling velocity limit value (vg1) and a second falling velocity limit value (vg2), which has a greater magnitude than the first falling velocity limit value (vg1), so that a high level of certainty in the detection of derailment states is thereby achieved.
本发明涉及一种用于检测轨道车辆的脱轨状态的方法和装置,其中借助于第一传感器(1)关于第一轮组端部部分(3)和借助于第二传感器(2)关于第二轮组端部部分(4)测量至少一个运动学变量,并且形成、处理和评估对应的测量信号。根据本发明,借助于至少一个计算单元(5)从测量信号计算关于第一轮组端部部分(3)的第一下降速度(vf1)的值和关于第二轮组端部部分(4)的第二下降速度(vf2)的值,并且借助于第一下降速度(vf1)和第二下降速度(vf2)与第一下降速度极限值(vg1)和第二下降速度极限值(vg2)的第一比较操作(6)来检测轨道车辆的脱轨状态,第二下降速度极限值(vg2)具有比第一下降速度极限值(vg1)更大的量值。由此实现了脱轨状态的检测中的高确定性水平。
