A monitoring apparatus includes a sensing circuitry configured to sense a locked or released state of a door of a railway vehicle, or sense an open or closed state of the door, and a processor. The processor acquires an output of the sensing circuitry, and position information in an opening or closing direction of the door, and determines an abnormality in a configuration related to an opening or closing operation of the door, based on a match between the acquired output of the sensing circuitry and the position information.

A control apparatus includes a first controller which controls an operation of a door of a railway vehicle, a second controller capable of controlling the operation of the door, and a diagnosis tester. The diagnosis tester performs a diagnosis related to an abnormality in the second controller when performing a start process which accompanies turning on power of the control apparatus.

A ramp system includes: a ramp main body provided in a door opening and configured to be able to advance from a vehicle floor toward a road surface; a ramp-state detection device configured to detect an advancing-retracting state of the ramp main body; a display device configured to display an image in a display area observable from an operator seat; and a UI controller configured to control display on the display device. The UI controller causes the display device to display a state image including an image indicative of the advancing-retracting state.

The present invention is to provide a vehicle door switch that is capable of adjusting the amount of movement made by a rod with ease and a method for attaching a vehicle door switch. A vehicle door switch includes a rod configured to move as a door is closed, a detecting unit configured to output a detection signal when one of ends of the rod has moved by a predetermined distance or more, and a limiting unit configured to limit the amount of movement made by the rod within a range where the detecting unit outputs the detection signal.

A door driving device includes a driving unit driving a door that opens and closes an entrance of a vehicle having a door case, and a control unit controlling the driving unit such that the door moves with a discontinuous acceleration during a period from when the door starts to open to when the door moves at a constant speed in an opening direction in which the door is retracted into the door case.

An opening and closing apparatus with a lock that is provided is capable of safely and promptly closing a sliding door, and also easily performing unlocking with a simple configuration. In an opening and closing apparatus with a lock for opening and closing sliding doors that are provided with elastic members at their door leading ends, output of an electric motor is transmitted to a rack-and-pinion mechanism or a lock mechanism. A control unit controls the electric motor such that a closing operation is performed, the closing operation operates the rack-and-pinion mechanism so as to move the sliding doors to a fully closed position and then displacing a link mechanism in a lock mechanism from an unlocking position to a locking position. Furthermore, the control unit controls the electric motor so as to reduce the output of the electric motor at a predetermined intermediate time point during the closing operation.

A vehicle sliding door device includes at least one sliding door which can be moved in a movement direction or a pivoting and sliding door which can be pivoted in a pivoting direction and which can be moved in a movement direction relative to a door frame that has a door opening, and a locking device for locking the at least one sliding door at least in the closed position that includes an emergency unlocking device, by which the at least one sliding door which is locked in the closed position can be unlocked in the event of an emergency. An emergency opening device is provided for at least partly opening the at least one sliding door or the pivoting and sliding door in the event of an emergency in an emergency unlocking state.

A system for opening and closing a sliding vehicle door includes a vehicle door that engages with the body in the closed position. A longitudinal track is fixedly mounted to an interior of the vehicle door. A hinged bracket is fixedly mounted to the vehicle body adjacent an opening defined by the vehicle body. The hinged bracket has a laterally compressed shape when the door is closed, and expands laterally outward when the door is opened. The door and the track fixed thereto slide longitudinally along the opened hinged bracket when the door is opened. The interface between the hinged bracket and the track remains at the same generally location relative to the vehicle body, and shifts relative to the vehicle door when the door is opened.

An operating mechanism for plug-type rail car doors includes first and second links connected to respective rotatable first support bars of the door. The links include respective elongated slots at least partially overlapping with one another, wherein each slot receives a respective cam. The cams are rotatable together about a rotational axis which is eccentrically arranged relative to both cams. An actuating lever is connected to the cams to enable an operator to rotate the cams about the rotational axis. The actuating lever is movable such that the first and second links are retracted relative to one another to simultaneously rotate the first and second support bars, and such that the first and second links are extended relative to one another to simultaneously counter-rotate the first and second support bars. A gear train may be provided between the actuating lever and the cams to reduce the necessary manual operating torque.

Systems and methods for monitoring an operation of a door of a public transportation vehicle are disclosed. In an embodiment, the system includes an optical sensor unit and a control unit. The optical sensor is arranged at a distance from the door and configured to record a movement of the door during an opening and/or a closing. The control unit is configured to (1) determine a position of a reference point of the door based on the recorded movement of the door, (2) determine a parameter of the movement of the door during the movement based on the determined position of the reference point, (3) determine a deviation of the parameter of the movement from a predetermined/allowed range of values of the parameter, and (4) determine an error in the operation of the door based on the determined deviation.
