Definitions

  • Such monitoring devices are also generally configured to alert the driver in the event of the presence of any other obstacle arranged in the path of the railway vehicle and which could compromise the safety of operation of the vehicle.
  • One of the aims of the invention is therefore to improve the operating safety of the railway vehicle.
  • the subject of the invention is a railway vehicle as mentioned above, in which the monitored region extends at least partially into the intermediate region.
  • a railway vehicle comprising a monitoring device in which the monitored region extends at least partially in an intermediate region of the vehicle, between a first and a second car, is particularly advantageous, since such a vehicle makes it possible to prevent accidents which may have place between two cars of the vehicle.
  • This is particularly advantageous for any type of connection between the first car and the second car of the vehicle, but is particularly interesting for vehicles without physical coupling between the first car and the second car, for which an individual is likely to try to pass between the two cars of the vehicle while the latter is in motion.
  • Fig 1 is a schematic representation seen from above of a railway vehicle according to the invention.
  • the elevation direction Z is defined according to the height of the vehicle and corresponds for example to the vertical direction when the vehicle is on a horizontal track.
  • the longitudinal direction X corresponds to the front-rear direction of the vehicle and the transverse direction Y corresponds to the width of the vehicle.
  • front and rear are defined with respect to the longitudinal direction X in the normal direction of movement of the vehicle.
  • left and right are defined with respect to the transverse direction Y in the normal direction of movement of the vehicle.
  • upper and lower as well as “top” and “bottom” are defined relative to the direction of elevation Z.
