Track-bound vehicle having a sensor device

Abstract

A track-bound vehicle has a first and a second car coupled to one another and at least one sensor device for monitoring a region between the two coupled cars. In order to allow particularly reliable monitoring of the region between the two coupled cars, the at least one sensor device is an optical sensor system having at least one optical transmitter on the side of the first car directed at the region to be monitored and at least one optical receiver on the side of the second car. The sensor is implemented for outputting a detection signal if the light path between the at least one optical transmitter and the at least one optical receiver is interrupted.

         15 . The track-bound vehicle according to  claim 14 , wherein in terms of a mounting height said at least one optical transmitter and said at least one optical receiver are each disposed underneath a car body of a respective one of said first and second cars. 
     
     
         16 . The track-bound vehicle according to  claim 14 , wherein said at least one optical sensor system is an infrared sensor system. 
     
     
         17 . The track-bound vehicle according to  claim 14 , further comprising at least one further optical sensor system and has, on said second car, at least one further optical transmitter which is aligned with said area which is to be monitored, and has, on said first car, at least one further optical receiver, and said further optical sensor system outputting a further detection signal when a light path between said at least one further optical transmitter and said at least one further optical receiver is interrupted. 
     
     
         18 . The track-bound vehicle according to  claim 14 , further comprising a controller device, said at least one optical sensor system is connected to said controller device and transmits the detection signal to said controller device. 
     
     
         19 . The track-bound vehicle according to  claim 18 , wherein the track-bound vehicle is configured such that a technical safety reaction of the track-bound vehicle is triggered at said controller device in response to a reception of the detection signal. 
     
     
         20 . The track-bound vehicle according to  claim 19 , further comprising a starting prevention device, the track-bound vehicle configured such that a said starting prevention device or braking of the track-bound vehicle is triggered at said controller device in response to the reception of the detection signal. 
     
     
         21 . The track-bound vehicle according to  claim 19 , further comprising a driver cab, the track-bound vehicle configured such that, at said controller device, a warning signal is transmitted to said driver cab and output there in response to the detection signal. 
     
     
         22 . The track-bound vehicle according to  claim 14 , wherein the track-bound vehicle is configured such that a monitoring of said area between said first and second cars is activated or deactivated in dependence on a respective operating situation of the track-bound vehicle. 
     
     
         23 . The track-bound vehicle according to  claim 14 , wherein the track-bound vehicle is configured to determine its coupling state, and the monitoring of said area between said first and second cars is activated or deactivated in dependence on a determined coupling state. 
     
     
         24 . The track-bound vehicle according to  claim 14 , wherein the track-bound vehicle is configured such that a monitoring of said area between said first and second cars is activated or deactivated in dependence on a presence of a door release signal. 
     
     
         25 . The track-bound vehicle according to  claim 14 , wherein the track-bound vehicle is configured to perform regular automatic function checking of said at least one optical sensor system. 
     
     
         26 . The track-bound vehicle according to  claim 14 , further comprising at least one camera which is aligned with said area between said first and second cars.
