Definitions

  • the present approach relates to a method for controlling a running board for a rail vehicle, a running board device and a rail vehicle.
  • Sensors for measuring a platform position that are installed in a vehicle are known. Sensor arrangements are also known that use sensors on the running board and on the vehicle, stationary, for the measurement.
  • the object of the present approach is to create an improved method for controlling a running board for a rail vehicle, an improved running board device and an improved rail vehicle.
  • This object is achieved by a method for controlling a running board for a rail vehicle, by a running board device and by a rail vehicle having the features of the independent claims.
  • a method for controlling a running board for a rail vehicle comprises a step of reading in a distance signal and a step of outputting a control signal.
  • the distance signal represents a distance between the running board and the platform in the horizontal and vertical directions.
  • the control signal is output using the distance signal in order to control the running board.
  • the rail vehicle can be, for example, a train for transporting passengers.
  • a Running board can be extended under a door of the rail vehicle.
  • the distance signal can represent the distance between the running board and the platform.
  • the control signal can be output as a column signal or as a ramp signal, depending on how large the distance is between the running board and the platform. If the control signal is output as a column signal, the running board can extend horizontally as a bridge towards the platform.
  • the running board can extend vertically, slightly tilted, as a ramp towards the platform if the control signal is output as a ramp signal.
  • the approach presented here can also be understood as a platform measurement on movable steps.
  • the control signal can be output in such a way that the running board can be extended in a substantially horizontal direction if the edge of the platform is the same as or within a tolerance range higher or lower than the running board.
  • the running board can thus be extended, for example, within an angular range of 10 degrees around a horizontal line.
  • the control signal can be output as a column signal so that the running board can extend as a bridge in a horizontal direction. This enables passengers to board and alight safely.
  • the tolerance range can include a maximum step height of 0 to 31 centimeters. This can enable comfortable and safe boarding and alighting for passengers.
  • control signal can be output in such a way that the running board can be tilted out when the edge of the platform is lower than the running board outside the tolerance range.
  • the control signal can be output as a ramp signal so that the running board can extend as a ramp. This enables passengers to board and alight safely.
  • the control signal can be output in such a way that the running board can be extended in a horizontal direction if the edge of the platform is lower than the running board by more than a threshold value.
  • the control signal can be output as a column signal so that the running board can extend as a walkway in a horizontal direction.
  • the running board can advantageously be extended as a walkway if it is not possible to extend it as a ramp.
  • the distance signal can be read by a sensor device measuring in a horizontal and a vertical direction and/or by a sensor device measuring at an angle to an outer wall of the rail vehicle. This means that the platform, in particular the edge of the platform, can be reliably detected.
  • This method can be implemented, for example, in software or hardware or in a mixture of software and hardware, for example in a control unit.
  • the approach presented here also creates a control device that is designed to carry out, control or implement the steps of a variant of a method presented here in corresponding devices.
  • This variant of the approach in the form of a control device can also solve the task underlying the approach quickly and efficiently.
  • control unit can be understood as an electrical device that processes sensor signals and outputs control and/or data signals depending on them.
  • the control unit can have an interface that can be designed as hardware and/or software.
  • the interfaces can, for example, be part of a so-called system ASIC, which contains a wide variety of functions of the control unit.
  • system ASIC system ASIC
  • the interfaces can be separate integrated circuits or to consist at least partially of discrete components.
  • the interfaces can be software modules that are present, for example, on a microcontroller alongside other software modules.
  • a running board device for a rail vehicle has a movable running board and an embodiment of a control device mentioned herein.
  • the running board can be extended without the help of train personnel.
  • the running board can have a sensor device.
  • the sensor device can be installed in the running board in such a way that it is protected from environmental influences such as rain, snow, etc., which can enable the sensor device to function reliably.
  • the sensor device can be designed to detect a distance to a platform or an edge of the platform in a horizontal direction with one sensor and in a vertical direction with another sensor.
  • the sensor device can be manufactured inexpensively. Furthermore, the sensors can be installed in the running board in a space-saving manner.
  • the sensor and the additional sensor can be arranged in the same orientation in the running board device.
  • the additional sensor can have a deflection device for deflecting a detection area. This means that the sensors can be installed quickly and in a space-saving manner.
  • the deflection device can be installed in front of the additional sensor to save space in order to detect a distance from the edge of the platform in a vertical direction. Due to the same orientation, the sensors can have a high degree of accuracy when detecting the distances.
  • a rail vehicle has an embodiment of a stepping board device mentioned herein.
  • the rail vehicle can be designed as a train or a tram.

  • the sensor device 120 is arranged, for example, within the running board 115 and designed to detect the platform 135.
  • the sensor device 120 has, for example, two sensors. One sensor detects the platform 135 in a horizontal area, the other sensor detects the platform 135 in a vertical area. More precisely, the sensors detect a distance between the running board 115 and an edge 110 of the platform 135.
  • the sensor device 120 is connected to the control unit 125 in a signal-transmitting manner, for example, in order to output a corresponding sensor signal to the control unit 125.
  • the running board 115 is extended as a walkway or as a ramp in the direction of the platform 135.
  • Fig.2 shows a representation of a running board 115 for an embodiment of a rail vehicle 100.
  • the running board 115 is similar or corresponds to the running board from Fig.1 .

  • the sensor device 120 detects the platform 135.
  • a sensor of the sensor device 120 measures the distance between the running board 115 and the platform 135 in the horizontal direction and another sensor measures the distance between the running board 115 and the platform 135 in the vertical direction.
  • the vertical detection area 300 and the horizontal detection area 200 are shown as examples and each have a conical shape. If the edge 110 of the platform 135 is within the tolerance range, the running board 115 is extended in the horizontal direction as a bridge towards the platform 135. However, if the edge 110 of the platform 135 is outside the tolerance range and lower than the running board 115, the running board 115 is tilted in the vertical direction and extended as a ramp towards the platform 135.

  • the maximum height of the detection range 200 corresponds to the maximum permissible step height between platform 135 and running board 115. If a platform 135 is detected here, the gap bridging operating mode is activated. If the platform 135 is lower than the detection range 200 of the primarily horizontal sensor, the running board 115 moves over the platform 135. and the second sensor, which primarily measures vertically, is activated and measures the vertical distance to the platform 135. If this is small and meets the requirements of a gap bridging, the gap bridging operating mode is activated.
  • the running board 115 switches to the ramp operating mode and continues to extend.
  • the predominantly vertical sensor can also check the maximum application area of the ramp by measuring the actual distance to the platform 135. If this is too large and operation as a ramp would not be permitted, the running board 115 is activated to a defined state, for example the gap bridging operating mode.
