Definitions

  • the invention relates to a method and a device for detecting a change in position of an at least partially switched off vehicle.
  • track-bound vehicles In the area of track-bound vehicles, there is a fundamental desire to be able to switch off or switch off a vehicle as completely as possible during a break in operation. On the one hand, this offers the advantage that the energy consumption and thus the operating costs are reduced; on the other hand, special devices for supplying energy to the parked vehicle can also be avoided as a result.
  • track-bound vehicles in the form of electrically powered rail vehicles usually have vehicle batteries which, even in the event that the track voltage is switched off - for example due to maintenance work - allow a basic electrical supply of the respective vehicle at least for a certain period of time.
  • Switching off those components of a vehicle that are required to determine the position of the vehicle is particularly problematic.
  • the actual position determination devices for example in the form of devices for satellite-based determination of the location or radar devices - this can particularly affect on-board control devices in the form of on-board units of train protection systems.
  • these there is also a desire for these to be switched off when the vehicle is not in use.
  • location information identifying the current position of the vehicle remains available in order to enable rapid, largely automated restarting of the vehicle.
  • a corresponding determination of a change in position when the vehicle is switched off or at least partially switched off is also referred to as “cold movement detection” (CMD).
  • CMD cold movement detection
  • a corresponding change in position may have taken place, for example, as part of a maneuvering or towing operation.
  • a method for detecting a change in position of a vehicle for the purpose of the CMD is, for example, from the German Offenlegungsschrift DE 10 2013 218 040 A1 famous.
  • a recording device is used to take a first picture of the surroundings of the vehicle.
  • a second recording of the surroundings of the vehicle is made by means of the recording device.
  • the change in position of the at least partially switched off vehicle is detected based on an at least partial comparison of the second recording with the first recording.
  • DE 10 2011 077 760 A1 describes a method for safety-related determination of a change in position of a switched-off rail vehicle, the vehicle having at least one axle sensor for generating an electrical signal depending on the angular position of a wheel axle of the rail vehicle and a locating system for determining the absolute position of the rail vehicle.
  • a status memory is set to a predetermined status when the rail vehicle is switched off. The stored status of the status memory is changed as a function of the rotation of the wheel axle through the interaction of the axle encoder with the status memory when the position of the switched-off rail vehicle changes.
  • the status of the status memory is checked and the extent of the status change is determined.
  • a change in the position of the rail vehicle is detected when the extent of the change in status of the status memory exceeds a predetermined threshold value in order to initiate a safety-related action in the locating system.
  • WO 2014/033290 A1 describes a control arrangement for a rail vehicle. At least one control device of the control arrangement is connected to receive sensor signals, the sensor signals each representing at least one speed. The control device is connected to a data bus of the rail vehicle via at least one bus connection for data exchange. The control device is designed to create a standstill signal based on the sensor signals and to transmit it to the data bus.
  • the control arrangement comprises a standstill determination device which is capable of receiving standstill signals via the data bus, the standstill determination device is designed to determine whether the rail vehicle is at a standstill based on standstill signals received via the data bus.
  • the sensor signals can be provided by suitable sensors, which can be designed as parts of the control arrangement.
  • the sensors can include axle speed sensors or rotational speed sensors of an anti-skid device, for example.
  • the object of the invention is to specify a method for detecting a change in position of an at least partially switched off vehicle that can be implemented with comparatively little effort.
  • This object is achieved according to the invention by a method for detecting a change in position of an at least partially switched off vehicle, in particular a track-bound vehicle, the change in position being detected by means of an anti-skid control device of the vehicle.
  • the invention it was recognized that detecting a change in position of a vehicle for the purpose of the CMD is often associated with additional effort, for example by adding additional components to the vehicle.
  • the invention solves this problem by using a component that is usually already present in the rail vehicle to detect the change in position.
  • the person skilled in the art understands the phrase "at least partially switched off vehicle” preferably as a dismantled vehicle. Certain components of the vehicle can remain switched on or at least not completely switched off or switched on. turned off. The person skilled in the art preferably understands an "at least partially switched on vehicle” as a vehicle which has been upgraded or has been upgraded again. Even with an upgraded vehicle, certain components may remain switched off or at least not be switched on completely.
  • the rail vehicle is preferably a rail vehicle.
  • the person skilled in the art preferably understands the “recognition of the change in position” to mean that it is recognized whether or not a change in position has occurred while the vehicle is at least partially switched off.
  • antiskid control device as a control of the vehicle which is provided for controlling an antiskid device of the vehicle.
  • the purpose of the anti-skid device is to prevent or suppress spinning and/or slipping of the wheels of the vehicle.
  • location information characterizing the current position of the vehicle is stored and the validity of the stored location information is confirmed if no change in position is detected.
  • the stored location information is location or location information characterizing the current position of the vehicle at the time the vehicle was switched off. This can have been determined by means of different, per se known locating devices, for example using a path encoder and/or a beacon, a device for satellite-supported determination of the location and/or a radar device.
  • this has the advantage that after the vehicle is switched on again, no additional actions are required by operating personnel in order to obtain a valid position of the vehicle.
  • neither manual input of current location information nor, for example, renewed determination of the location information for example by reading location markers, ie for example beacons, by moving the vehicle in a restrictive operating mode, is required.
  • the detection takes place on the basis of a rotation signal, the rotation signal being generated on the basis of detection of a rotation of an axle of the vehicle by means of an axle detection device.
  • the rotation signal represents a particularly expedient basis for recognizing the change in position by means of the anti-skid control device.
  • the anti-skid control device is preferably connected in terms of signals to the axis detection device for the purpose of transmitting the rotation signal.
  • the axle detection device includes a distance encoder of the vehicle.
  • travel encoders that are already present in the rail vehicle can usually be used to generate the rotary signal will. This further development can therefore be implemented with little effort.
  • the energy supply of the displacement encoder is preferably independent of an energy supply of the vehicle, for example the vehicle battery.
  • the distance pulse generator is self-sufficient with regard to the energy supply and does not require any energy supply from the vehicle while the vehicle is at least partially switched off.
  • the displacement encoder comprises a generator which is designed to obtain energy that supplies the displacement encoder from the rotation of the axle of the wheel. It can be obtained, for example, before the vehicle is at least partially switched off during normal operation, with the energy obtained being temporarily stored in a memory, for example a battery, of the displacement encoder so that it is available when the rotation is detected.
  • the generation of energy from the rotation of the axle can also take place, for example, in each case during the movement of the at least partially switched off vehicle.
  • the anti-skid control device when the vehicle is at least partially switched off, assumes a standby state, in particular a sleep mode.
  • the standby state is preferably a state which has a lower energy consumption compared to a state of normal operation.
  • this embodiment represents a particularly energy-saving solution.
