摘要： OBJECT: To accurately detect a derailment, so as to prevent a railway vehicle from traveling when its wheels have become disengaged from a rail without an operator being aware of it, thus improving safety after the derailment occurs.
MEANS: For example, a transmission line 5 configured to be broken when it comes into contact with a rail 4 is installed on a disengagement prevention guide 1 attached to an axle box 3 of a railway vehicle. One end 5a and the other end 5b of the transmission line 5 are connected to a determination unit 6 to monitor continuity of the transmission line 5. In the event of a derailment, the determination unit 6 determines that a derailment has occurred when the disengagement prevention guide 1 makes contact with the rail 4 and the transmission line 5 breaks, thereby interrupting the continuity of the transmission line 5.

摘要： An actuator is installed between a vehicle body and a bogie frame of a railroad vehicle mounted with a bolsterless bogie, for example. Sensors are installed in at least one of the vehicle body, the bogie, and the wheelset. One or more parameters having a correlation with a steady lateral force are computed on the basis of state quantities obtained by using the sensors while traveling, to determine a thrust command value to be output to the actuator, by applying a predetermined transfer function to the computed value. Concurrently with determining the thrust command value, one or more parameters having a correlation with a fluctuating lateral force are computed to determine a thrust command value to be output to the actuator, by applying a predetermined transfer function to the computed value. These two thrust command values are combined to determine the thrust output to the actuator.
It is possible to effectively reduce the maximum lateral force generated while traveling, thus making it possible to increase the maximum traveling speed.
摘要翻译：例如，在车体和安装有无摇架转向架的铁路车辆的转向架之间安装有致动器。传感器安装在车体，转向架和轮对中的至少一个中。基于通过在行驶时使用传感器获得的状态量来计算与稳定横向力相关的一个或多个参数，以通过将预定的传递函数应用于计算出的运动来确定要输出到致动器的推力指令值值。同时确定推力指令值，通过对计算出的值应用预定的传递函数，计算一个或多个具有与波动的横向力相关的参数，以确定要输出到致动器的推力指令值。这两个推力指令值被组合以确定到执行机构的推力输出。可以有效地减少行驶时产生的最大横向力，从而能够提高最大行驶速度。
