Definitions

  • the present invention relates to a vehicle, in particular a rail vehicle, having a. a monitoring sensor arranged in the area of a first end of the vehicle and/or a second end of the vehicle, which is set up to monitor a vehicle environment in relation to at least one monitoring criterion during a stopping maneuver of the vehicle at a bus stop, and b. a controller signal-connected to the monitoring sensor(s).
  • a “vehicle” can be understood to mean, for example, a public transport vehicle.
  • the vehicle can be a rail vehicle, e.g. B. a train, a streetcar, a tram, a subway, etc.
  • a vehicle can also be a wheeled vehicle such as a bus.
  • the present invention is therefore based on the object of providing a vehicle and a method for monitoring a bus stop during a stopping maneuver of a vehicle at the bus stop, with which the disadvantages and dangers described can be overcome or at least reduced.
  • a vehicle in particular a rail vehicle, having a. a monitoring sensor arranged in the area of a first end of the vehicle and/or a second end of the vehicle, which is set up to monitor a vehicle environment in relation to at least one monitoring criterion during a stopping maneuver of the vehicle at a bus stop, and b. a controller signal-connected to the monitoring sensor(s).
  • the vehicle is characterized in that the controller is set up to generate a control command on the basis of the at least one monitoring criterion and to control a door or boarding system of the vehicle in accordance with the control command.
  • the stated object is achieved with a method for monitoring a stopping platform during a stopping maneuver of a vehicle at the stopping platform, comprising: driving a vehicle onto the stopping platform and executing a stopping maneuver at the stopping platform; Monitoring a vehicle environment with respect to at least one monitoring criterion with a monitoring sensor arranged in the area of a first end of the vehicle and/or a second end of the vehicle; using a controller: generating a control command based on the at least one monitoring criterion; Controlling a door or boarding system of the vehicle according to the control command.
  • the first end of the vehicle is preferably a front area of the vehicle, ie a front end.
  • the second end of the vehicle is preferably a rear area of the vehicle, ie a rear end.
  • a rail vehicle can be made up of several parts (e.g. wagons). Each member (or wagon) can be understood as a vehicle within the meaning of the invention and can have a front and rear end. Also, a multi-member vehicle may be considered a vehicle as a whole, and a front vehicle end may be provided in the area of a front member (cars), while a rear vehicle end is provided by a rear area of a rear member. The same applies in the event that the vehicle is a wheeled vehicle such as a bus. This is because buses can also be constructed in one or more sections.
  • the aforementioned signaling connection between the monitoring sensor(s) and the controller can be wired or wireless.
  • the controller can be a central processing unit of the vehicle or a vehicle component.
  • the controller can also be located on an external server.
  • each monitoring sensor can be connected to a microcontroller, with the microcontrollers in turn being connected to a central processing unit. This can also be arranged inside the vehicle or a respective vehicle element, alternatively externally.
  • the signaling connection can be provided via suitable—and per se known—signal communication interfaces.
  • a signal communication interface is preferably assigned to a respective monitoring sensor and to the controller.
  • the signal communication interface assigned to the monitoring sensor can be part of a microcontroller connected to the monitoring sensor or can be connected to it. It can be provided that several monitoring sensors are each assigned separate signal communication interfaces, so to speak several monitoring sensors can be assigned to one and the same signal communication interface. Signals, commands and data can be sent via a signaling connection.
  • the monitoring sensor is set up to monitor a vehicle environment in relation to at least one monitoring criterion when the vehicle is stopping at a bus stop.
  • This can be done in such a way that on the part of the monitoring sensor, corresponding monitoring data (e.g. image and/or video data with a camera as a monitoring sensor, radar data with a radar sensor as a monitoring sensor, ultrasonic data with an ultrasonic sensor as a monitoring sensor, microwave data with a microwave sensor as a monitoring sensor, lidar data with a lidar sensor as a monitoring sensor, infrared data with an infrared sensor as a monitoring sensor) and then checked in relation to the monitoring criterion.
  • corresponding monitoring data e.g. image and/or video data with a camera as a monitoring sensor, radar data with a radar sensor as a monitoring sensor, ultrasonic data with an ultrasonic sensor as a monitoring sensor, microwave data with a microwave sensor as a monitoring sensor, lidar data with a lidar sensor as a monitoring sensor, infrare
  • the data are examined or read out under predeterminable test criteria, which can be done with computer support, for example directly in a microcontroller connected to one or more monitoring units, another computing unit connected thereto or in the controller. Provision can be made for the data to be stored temporarily or for a longer period on a storage unit.
  • a predefinable test criterion can be based on a qualitative presence of a monitoring criterion, but also on a quantitative or content-related analysis of the data.
  • the data can be examined or read out using predeterminable test criteria using software, a routine, an algorithm (also based on artificial intelligence).
  • the invention can also include a method in which a vehicle according to the invention carries out a stopping maneuver.
  • a vehicle environment is monitored with regard to at least one monitoring criterion.
  • Each monitoring sensor of the vehicle can carry out such monitoring.
  • a control command is generated on the basis of the at least one (detected) monitoring criterion, which is then subjected to an evaluation, and a door or boarding system of the vehicle is activated in accordance with the control command.
  • a method for monitoring a stopping platform during a stopping maneuver of a vehicle at the stopping platform comprising: accelerating a vehicle to the stopping platform and executing a stopping maneuver at the stopping platform; Monitoring a vehicle environment with respect to at least one monitoring criterion with a monitoring sensor arranged in the area of a first end of the vehicle and/or a second end of the vehicle; using a controller: generating a control command based on the at least one monitoring criterion; Controlling a door or boarding system of the vehicle according to the control command.
  • a plurality of monitoring sensors to be arranged in the area of the first and/or second end of the vehicle, with at least one monitoring sensor being arranged transversely to a vehicle longitudinal axis on the left and right of the vehicle.
  • One or more monitoring sensors can thus be arranged on the left and/or right side of the vehicle (at each end of the vehicle).
  • An arrangement of monitoring sensors on both sides of the vehicle is advantageous in order to be flexible with regard to the left or right-hand bus stops in relation to the vehicle and to be able to monitor them.
  • the respective monitoring sensors are arranged countersunk in relation to a vehicle outer paneling. This means that the monitoring sensors do not physically protrude with respect to the vehicle exterior panel or an external surface of the vehicle. This can provide aerodynamic benefits when driving the vehicle as well as minimize the risk of damage when colliding with surrounding objects.
  • the respective monitoring sensors are optical sensors or sensors based on electromagnetic radiation.
  • the optical sensors can be cameras, while the sensors based on electromagnetic radiation can be radar sensors, ultrasonic sensors, microwave sensors, lidar sensors, or infrared sensors.
  • the monitoring sensors can be 3D sensors that can monitor an observation field that extends in three-dimensional space.
  • the monitoring sensors are set up to monitor the vehicle surroundings in the direction of the bus stop. Monitoring can take place both when the vehicle drives onto the bus stop and when the vehicle is already at a standstill, e.g. B. in the immediate vicinity of the bus stop.
  • the monitoring criterion relates to a vehicle distance from the bus stop, a relative height difference between the vehicle and the bus stop, or a personal criterion for people on the bus stop. Both the vehicle distance and the height difference are preferably measured at predetermined reference points.
  • the vehicle distance can be determined in relation to the monitoring sensors. Since these are preferably arranged sunk in relation to a vehicle outer paneling, it can then be the distance between the holding platform and the vehicle outer paneling.
  • the system can be adjusted or calibrated in such a way that a height difference between the stopping walk and a height level of a leading edge of a door portal is determined.
  • the floor level of a vehicle interior can be defined as a reference height.
  • Other reference points can also be defined.
  • a personal criterion for people on the stopping platform can be, for example, a number of people or a number/size of specific passenger groups. Distances that can be determined between potential passengers (on the bus stop) or a passenger density per monitoring area can also be understood as monitoring criteria.
  • the controller is set up to issue a control command relating to the selection of a treadle as part of the boarding system, the setting of an extension width of the treadle, an opening or opening width of at least one door leaf associated with the door system to generate and to control the door or boarding system accordingly.
  • a control command relating to the selection of a treadle as part of the boarding system, the setting of an extension width of the treadle, an opening or opening width of at least one door leaf associated with the door system to generate and to control the door or boarding system accordingly.
  • a specific footplate e.g. of a specific size, a specific mechanical stability, a specific type
  • a specific extension of the footplate e.g. of a specific extension of the footplate.
  • a control command can be generated in the event of detection of a certain (critical) number of people on the bus stop or a (critical) number/size of certain passenger groups, (critical) distances between passengers on the bus stop, a (critical) passenger density per monitoring area, which prevents a door from being opened/a step plate from being extended as part of the door or boarding system for safety reasons (i.e. preventing getting out and getting into the vehicle), or which causes certain doors to be opened to ensure the safety of people entering and exiting the vehicle to increase exiting people.
  • a control command can then be generated by the controller which, for safety reasons, prevents a door from being opened/a step plate from being extended as part of the door or boarding system, in order to prevent passengers from stumbling, for example.
  • the same applies to other safety-relevant events in the vehicle environment that are detected by monitoring.
  • the controller is set up to generate a control command for a passenger guidance system.
  • monitoring in particular the personal criterion
  • a passenger guidance system can be used for this purpose, which can guide the passengers via visual or acoustic displays. This passenger guidance system can be coupled to the mentioned controller.
  • Suitable means can be provided for all of the monitoring, evaluation and control tasks mentioned.
  • the 1 shows a vehicle 1 according to the invention in a first embodiment of the invention in a highly schematic top view.
  • the vehicle 1 is a rail vehicle that runs on rails 2 .
  • monitoring sensors 3 are arranged in the area of a first vehicle end 11 and a second vehicle end 12, namely on the left and right in relation to a vehicle longitudinal axis A.
  • the monitoring sensors 3 physically project outwards in relation to a vehicle outer paneling 5, i.e. close not flush with these.
  • the respective monitoring sensors 3 are set up to monitor a vehicle environment 7 during a stopping maneuver of the vehicle 1 at a bus stop 4 with regard to at least one monitoring criterion.
  • the vehicle environment 7 can be a monitoring area of the monitoring sensors 3, ie z. B. a field of view accessible via the monitoring sensors 3 .
  • the vehicle also includes a controller (not shown) that is signal-connected to the monitoring sensors. The controller is set up to generate a control command based on the at least one monitoring criterion, and to control a door or boarding system of the vehicle 1 according to the control command.
  • the monitoring sensors 3 are not arranged on the left and right of the vehicle 1, but in the area of a vehicle front 21 and a vehicle rear 22. The same applies to the exemplary embodiment according to FIG 4 .
  • a stopping platform 4 On the left side of the vehicle 1, a stopping platform 4 is arranged, on which a person 6 is located.
  • the person 6 can be detected with the monitoring sensor 3 , the person 6 being located within a vehicle environment 7 which can be monitored by means of the monitoring sensor 3 .
  • the monitoring sensors 3 there can be used to monitor both the vehicle surroundings in the area of the bus stop 4 and in the area of the rails 2 . So e.g. B. in an observation field of the monitored vehicle environment 7 located persons 6 or objects 8 (located here on the rails 2) can be detected.
  • figure 5 relates to a further embodiment variant in which the monitoring sensors 3 are arranged sunk in relation to a vehicle outer paneling 5 .
  • This can also be used, for example, to monitor people 6 located on a stopping platform 4 .
  • monitoring sensors can also be used—as described in the introduction—to determine the distances between the vehicle 1 and the stopping platform 4 or height differences thereto.
