Definitions

  • the present invention relates to a method for displaying passenger information on a passenger transport vehicle which has an interior and at least one window which has an inside facing the interior and an outside.
  • the present invention relates to a passenger information system for displaying passenger information on a passenger transport vehicle, in particular for carrying out such a method, and a passenger transport vehicle with such a passenger information system.
  • Passenger information systems for passenger transport vehicles such as buses, trains (particularly local rail vehicles), ships and the like are generally known.
  • the passenger information systems are used to display passenger information such as a bus line, a train line, a terminus or the like on the vehicle.
  • passenger information systems have display means that can be implemented electromechanically or electrically/electronically, for example.
  • Electromechanical displays of passenger information systems are often implemented using bistable display elements ("flip dots"). Furthermore, segment displays are also known.
  • the display devices used here are usually box-shaped and are installed in the interior of the vehicle. Corresponding recesses for the display devices are provided in the body of many passenger transport vehicles. However, it is also known to arrange these display devices behind windows of the passenger transport vehicle.
  • the display devices are often connected to a control device that can be operated, for example, by a driver or by a higher-level control center of a local transport system.
  • the document US 2012/0089273 A1 discloses a method for displaying a graphical representation on a substantially transparent screen of a vehicle.
  • the graphic representation describes a desired communication.
  • the method includes monitoring the desired communication, monitoring an external presentation mode to present the desired communication, determining the graphical representation describing the desired communication, registering a location of the graphical representation on the substantially transparent screen, to realize communication to the outside outside of the vehicle.
  • the method further includes displaying the graphic representation on the substantially transparent screen, wherein light emitting particles or microstructures enable a luminescent display over a predetermined region of the screen while allowing transmission therethrough.
  • a method for displaying passenger information on a passenger transport vehicle according to claim 1 which has an interior and at least one window which has an inside facing the interior and an outside, with at least one display section of the window for displaying passenger information is formed, with the step of displaying the passenger information in the display section such that the passenger information can be read on the outside of the display section.

  • the basic idea of the present invention is that no box-shaped display devices have to be used for the passenger information if a display section is provided or reserved in or on the window of the passenger transport vehicle, within which the passenger information can be displayed. As a result, large degrees of freedom are released in the interior design of the passenger transport vehicle.
  • passenger information systems can be implemented inexpensively. There may also be a large degree of freedom in the exterior design of the passenger transport vehicle, since the windows can have a large surface area.
  • the display section of the window is preferably an area of the window that does not serve as a viewing area.
  • the passenger information is projected on the inside of the display section.
  • the projection can be an image of the passenger information.
  • a very high resolution can preferably be achieved here, so that the passenger information can be presented in many variants and in an attractive manner.
  • the passenger information is projected onto the inside of the display section in a mirror-inverted manner.
  • the passenger information can be read mirror-correctly on the outside of the passenger transport vehicle.
  • the display section of the window has an image-generating layer, in particular a transreflective layer and/or a ground-glass screen.
  • the image-generating layer which can be in the form of a film, for example, serves as a kind of "screen" for the projection.
  • the image-generating layer is constructed in such a way that the projected image is displayed on it and can be read from the outside.
  • the image-generating layer can be arranged on the inside of the display section of the window, but can also be arranged on the outside of the display section of the window. It is also possible to use the image-giving To integrate layer in the window, for example in the form of an intermediate film.
  • the imaging layer has the function of a “ground glass”.
  • Such a screen is usually made of a transparent plastic such as a film and usually has a smooth and a frosted side.
  • the image projected from an image source is thereby reproduced in the ground glass and can be read from the outside.
  • Such a screen can also be formed on the outside of the display section, on its inside and/or as an intermediate film of the window.
  • the foil is preferably transparent when no image is projected onto it, so that the display section is preferably not visible at all or only slightly when the image source is switched off.
  • the image source can be constructed like a "beamer”, ie with LED, LCD or DLP image elements, for example. Furthermore, the image source can also be constructed as is usual with head-up displays.
  • the display section is a section of a window through which passengers can look outside from the interior.
  • the window is structured to include a viewing area and the display section.
  • the display section can be separate from the viewing area, but can also partially or completely overlap with the viewing area.
  • the display means have an image source that emits or projects an image with passenger information, for example a beamer or the like.
  • At least one image source is arranged in a roof area of the passenger transport vehicle and/or at least one image source is arranged in the area of a dashboard of the passenger transport vehicle.
  • the image source is offset from a central axis perpendicular to a plane of the display section and, if necessary, aligned at an angle thereto, ie at an angle of less than 90°.
  • the image of the passenger information is projected in such a way that the distortions caused by the offset are eliminated from the outset.
  • the passenger information system has at least one brightness sensor in order to be able to automatically adjust the brightness of the projection as a function of the brightness of the surroundings.
  • a passenger transport vehicle is shown schematically and generally designated 10 .
  • the passenger transport vehicle 10 is a bus, such as is used in local transport, for example.
