Definitions
- the invention relates to a method for operating a rail vehicle along a railway line.
- Rail vehicles typically have a train protection unit which, when an imminent danger situation is detected, in particular by recognizing a so-called “danger point" on the traveled route, introduces safety measures
- train control units When introducing restrictive measures for driving, conventional train control units are based on the most critical one mentioned above The measures taken are therefore in most cases not adapted to the actual driving situation, in particular they are too restrictive in relation to the actual driving situation.
- the invention has for its object to provide a method for operating a rail vehicle along a railway line through which these disadvantages can be avoided.
- a travel of the rail vehicle along the railway line has a travel section which ends before or at a danger point of the railway line
- the rail vehicle is braked - in a protection mode - at the beginning of the driving section, starting from a first speed during a braking phase during the Bremsphase a kinetic energy of the kinetic energy of the rail vehicle is absorbed by an energy absorption unit of the rail vehicle
- the braking phase follows an energy reduction phase, in which at least a portion of the energy absorbed by the power receiving unit is released and the driving section is determined such that one for a vehicle energy representative energetic state parameter, which takes into account at least the energy present in the energy absorption unit, meets a condition at the danger point.
- the determination of the driving behavior takes into account an energetic state of the rail vehicle.
- the driving behavior can be adapted at least to the actual state of the energy absorption unit.
- the design of the rail vehicle, in particular the energy absorption unit no longer needs to be adapted as conventionally to the most critical conceivable danger case, since the driving behavior can be adapted to avoid the occurrence of an impermissible driving situation.
- the introduction of restrictive measures can be better adapted to this energetic state.
- the determination of the travel section comprises in particular at least the determination of the parameters which serve for defining the driving behavior of the rail vehicle in the travel section, in particular for defining the at least one braking phase and the at least one energy reduction phase.
- the determination can at least determine the start and end points of the braking phase on the track, a target speed to be reached at the end of the braking phase and the for include the energy reduction phase envisaged for the energy reduction phase.
- the rail vehicle which reaches a target speed at the end of the braking phase, is preferably operated at a constant speed during the energy-reduction phase following the braking phase.
- the driving section has at least the braking phase and the subsequent energy reduction phase. After this can be in
- Driving section take a second braking phase, which in turn followed by a second energy reduction phase. A renewed acceleration during the driving section is expediently prevented.
- a parameter that is "representative" for a parameter or, in other words, a parameter "for" a parameter can be the parameter itself or a variable from which the value of the parameter can be uniquely derived
- an electrical variable may be representative of a temperature, and the danger point may correspond to the beginning of a gradient section.
- the state parameter take into account the instantaneous mass of the rail vehicle.
- the state characteristic is representative of the vehicle energy resulting from the kinetic energy and the potential energy of the rail vehicle and the energy present in the energy absorption unit, whereby can be achieved by an advantageous adaptation of the driving behavior to the actual driving conditions.
- the “potential energy” of the rail vehicle depends on a height difference corresponding to the difference between the height of the current track position of the rail vehicle and the height of the point on the track to which the rail vehicle after braking with the maximum available braking power
- this energy corresponds to the potential energy which, if positively contributed, must be overcome by the rail vehicle during braking or, in the case of a negative contribution, supports the braking process "should be understood in particular the geographical altitude relative to the sea level.
- the condition requires that the vehicle energy at the danger point corresponds to or falls below a predetermined maximum permitted vehicle energy.
- the decisive for the design of the rail vehicle, in particular the design of the energy absorption unit energy level can be set lower than known solutions, since the occurrence of energetically inadmissible driving situations can be avoided by an adaptive driving.
- the maximum allowable energy suitably corresponds to the maximum energy which can be absorbed by the energy absorption unit by design.
- the energy absorbing unit comprises, in a preferred embodiment, at least one set of elements intended to receive energy in the form of heat.
- a maximum energy that can be absorbed by this set corresponds to a maximum amount of energy that can be absorbed by the latter, based on a situation in which the elements have the ambient temperature, without this leading to a serious functional impairment, in particular to a ner destruction of the elements leads. The maximum amount of energy therefore depends on the thermal capacity of the elements.
- the energy reduction phase for this set corresponds to a cooling phase, in which the absorbed energy is delivered to another system, eg the ambient air.
- the energy absorbing unit may in this case comprise a set of braking device components of the rail vehicle which absorb at least part of the kinetic amount, in particular the kinetic amount, in the form of heat.
- heating elements of the energy absorbing unit in this case are e.g. Brake discs and wheel discs of the rail vehicle correspond.
- the maximum amount of energy that can be absorbed by these elements corresponds to the amount that can be absorbed before serious changes occur in the frictional engagement and therefore in the braking force produced. This maximum amount of energy is defined by the brake disk design and a given type of lining.
- heating elements of the energy absorbing unit in this case e.g. Braking resistances correspond.
- the maximum amount of energy that can be absorbed by these elements is also design-related in this case.
- alternative or additional embodiment may be components of a retarder, wherein a heating element of the energy absorption unit is formed in this case of a retarder, in particular a retarder.
- alternative or additional embodiment may be components of an eddy current brake, wherein a heating element of the energy absorption unit in this case corresponds to a component in which eddy currents are induced.

- the energy delivered can also be stored and / or used for the operation of a consumer.
- the current value of the energetic state parameter be detected, the energetic state parameter at the danger point be extrapolated from the current value and the protection mode be initiated if the extrapolated state parameter does not satisfy the condition.
- the journey can be continued without change, in particular without braking intervention.
- the extrapolation is carried out in particular under the assumption of maintaining the current driving style, in particular the current speed.
- a parameter for the energetic state may be a temperature parameter. It is also possible, in particular for extrapolation, to take into account data on the braking capacity of the rail vehicle. This data may e.g. Braking capacity data entered before departure in the so-called "train data input"
- the extrapolation is advantageously carried out on the basis of data of the railway line, which have at least one height profile of the railway line, wherein the danger point corresponds to the beginning of a slope section.
- a parameter for the energy difference between the maximum permissible vehicle energy and the extrapolated vehicle energy at the danger point is expediently determined on the basis of the extrapolated state parameter.
- the determination of the driving section in the protection mode comprises the calculation of a target speed to be reached at the end of the braking phase.
- the target speed depends on the energy difference.
- the target speed is calculated in such a way that it effects a kinetic energy and a potential energy at the danger point whose sum is at least smaller than the maximum permissible vehicle energy by the amount of the energy difference.
- a first mode of the protection mode is proposed, in which at least the kinetic amount is reduced during the energy reduction phase as an energy reduction amount. If the target speed is calculated to produce kinetic energy and potential energy at the danger point whose sum is less than the maximum allowable vehicle energy by the amount of the energy difference, that speed will set an upper limit for that during the first mode Braking phase to be set ness. As a result, a minimum speed restriction can be achieved in comparison with further adaptation scenarios.
- the target speed is calculated such that less energy than the kinetic amount is dissipated during the energy reduction phase as an energy reduction amount.
- a shorter energy reduction distance than in the first mode can be achieved if a target speed is set below the above upper limit.
- a target speed can cause a kinetic energy and a potential energy at the danger point whose sum is smaller than the maximum permissible vehicle energy by more than the energy difference, so that a complete reduction of the kinetic amount during the energy reduction phase is not necessary.
- the determination of the travel section in the protection mode comprises in particular the calculation of the energy reduction phase route required for the energy reduction phase as a function of an energy reduction amount on the basis of a cooling power characteristic of the energy absorption unit.
- the determination of the driving section in the protection mode expediently comprises the calculation of the braking-phase path required for producing the target speed as a function of the braking capacity data of the rail vehicle.
- the driver is prompted in a request mode to initiate the braking phase at the beginning of the driving section.
- an adaptation of the driving behavior advantageously takes place on the basis of a service braking initiated by the driver, which is carried out with moderate braking deceleration. This is gentle on material and is - with respect to the passenger comfort - at a provided for the transport of passengers rail vehicle advantage.
- the braking phase in a
- Forced intervention mode automatically initiated by a train control unit. It can be braked with the maximum available braking power.
- the forced intervention mode can be applied in particular when a deficient response to the prompting mode prompting is detected.
- a poor response may be a non-response or the initiation of braking with insufficient braking power.
- High safety can also be achieved if, in an emergency mode, the rail vehicle is braked to a standstill, whereby the emergency mode is initiated when the presence of an error in the energy reduction phase is detected.

- the railcar 12.1 has drive axles 14, which are driven by at least one drive motor (not shown).
- the rail vehicle 10 also has a braking device 22.
- This comprises at least one electrically and / or mechanically operable brake unit 24 designed as a friction brake unit (shown schematically) and an electric brake unit 26 which is formed by the drive unit 18.

- the structure of a drive unit 18 and a brake device 22 in a rail vehicle is well known and will not be explained here.
- the considered embodiment of the rail vehicle 10 with the association of carriages 12 - ie an embodiment as a so-called multiple unit train - is exemplary.
- the rail vehicle 10 may be formed as a single traction vehicle, such as a locomotive, which is intended for use with unpowered passenger coaches or freight cars.
- the reference of electrical energy from an external power supply 20 is also exemplary.
- the rail vehicle 10 may be equipped with its own energy source, such as in particular an internal combustion engine, which drives the drive axles 14 or by which electrical energy is generated for the power supply unit 16.
- the rail vehicle 10 further includes a train control unit 28.
- This comprises a unit 30, which is intended to interact with trackside equipment 31, and a controller 32.
- the unit 30 comprises, in particular, a train antenna.
- the interaction of the trackside equipment 31 and the train control unit 28 may trigger engagement of the train control unit 28 in the control of the rail vehicle 10 in the presence of certain operating situations.
- the train control unit 28 may e.g. when a maximum permitted speed is exceeded or when the main signal is shown to be inadvertently passing the stop, emergency braking of the rail vehicle 10 is triggered.
- Known systems of train protection are e.g. the PZB (Selective Train Control), LZB (Line Train Influence), ATP (Automatic Train Protection), TBL (Transmission Balancing)
- the function of the train protection unit 28 is based on train information, which depends on the configuration of the rail vehicle 10 and on the current operating states of its facilities. In particular, information about its braking capacity must be transmitted to the train control unit 28 before a service recording of the rail vehicle 10 (so-called "train data input") .This information is evaluated by the train control unit 28, in particular to take account of a braking distance.
- FIG. 2 shows an overview of the information that is taken into account by the train protection unit 28 for carrying out the methods described in more detail below.
- data BSD of the railroad track to be traveled is also added.
- at least one information M about the loading of the rail vehicle 10 and at least one information E Q is considered via a heat contained in the braking device 22. This information E Q can be obtained in particular from the evaluation of a temperature characteristic for a temperature of the braking device 22.
- the controller 32 of the train control unit 28 is equipped with at least one arithmetic unit (not shown) and at least one memory unit 33, in which corresponding executable programs are stored.
- the information BVD and BSD are expediently stored in a database, not shown, of the rail vehicle 10 to which the train control unit 28 has access.
- the information POS, V, M and E Q are usually detected via corresponding sensor units, not shown.

- the information E Q forms a state parameter of the energy absorption unit 34 which is responsible for the energetic state of the power receiving unit 34 is characteristic. This information E Q corresponds in particular to the sum of the in the Elements of the energy absorption unit 34 contained amounts of energy.
- FIG. 3 shows a first diagram, on the basis of which a method performed by the train protection unit 28 for operating the rail vehicle 10 along a railway track 36 is explained.
- the railway line 36 has a danger point 38, which corresponds to the beginning of a slope section 40 of this railway line 36.
- the approaching of the danger point 38 is determined on the basis of the data BSD as route information.
- these data BSD include at least one height profile, which is shown in the diagram.
- the rail vehicle 10 is also characterized by a maximum permitted energy E max .
- the maximum permitted energy corresponds to the maximum amount of energy that can be absorbed by the brake device 22 as a result of the design. This is determined in advance and decisive for the design of the braking device 22.
- the maximum permitted energy E max - and therefore the design of the braking device 22, can be chosen such that in all conceivable driving situations, the vehicle energy E tra is less than E max .
- the "least favorable" energy state of the rail vehicle 10 is decisive, assuming that the rail vehicle 10 is at the maximum speed, a critical mass and in a section with a critical mass
- Track inclination is located.
- this requires high design requirements for the braking device 22 and possibly an oversizing of these, in particular with regard to permissible temperatures and energy absorption capacities of the brake components.
- the maximum permitted energy E max may be smaller than be set, whereby a structurally simpler interpretation of the braking device 22 can be achieved.
- an energy state characteristic variable representative of the vehicle energy Etrain is determined continuously or at regular time intervals. As a criterion for the operation of the rail vehicle 10 then applies that the current vehicle energy E tr ain may not exceed the maximum permitted energy E max . This situation could occur, in particular, when the rail vehicle 10 is overloaded - that is, has a mass above a predetermined maximum mass, travels along a downslope with an incline over a predetermined maximum path incline, and / or energy absorbing unit 34 energy harvesting components are already in a preheated state.
- the energy state characteristic value is representative of the vehicle energy E tr a resulting from the kinematic energy E k i n , the potential energy E pot and the energy E Q contained in the energy absorption unit 34.
- the above-mentioned information M, V, BSD, POS, BVD and E Q are used.
- the energetic state parameter of the vehicle energy corresponds to E tr ain itself.
- a variable can be selected for the state parameter from which the vehicle energy E tr ain can be derived unambiguously.
- the instantaneous potential energy E pot of the rail vehicle 10 is defined by the mass M of the rail vehicle 10 and a height difference. This corresponds to the
- the vehicle energy E tr ainGF is extrapolated at danger point 38.
- the extrapolation is based on the assumption of a maintenance of the current driving style up to the danger point 38. Due to the slope section 40, the vehicle energy E tr ainGF at the danger point 38 is greater by the amount of a potential energy.
- This potential energy depends on the mass M of the rail vehicle 10 and the height difference between the danger point 38 and the point on the track at which the rail vehicle 10 would come to a halt when performing braking starting at the danger point 38 with the maximum available power.
- the height difference can correspond to the total height difference of the slope section 40.
- the train control unit 28 initiates a protection mode with the measures described below. If the extrapolated vehicle energy E tr ainGF has a permissible level, the driving mode up to the danger point 38 can be maintained.
- the protection mode to be initiated aims at bringing the rail vehicle 10 into an energetic state at the latest at the danger point 38, in which case the condition
- a driving section 42 is determined by the train control unit 28, which ends at the latest at the danger point 38.
- the driving section 42 is determined in such a way that the vehicle energy E tra i n at the danger point 38 corresponds to the maximum permitted energy E max or falls below it.
- the travel section 42 is determined by determining its beginning and a driving style of the rail vehicle 10, which brings the rail vehicle 10 in the desired energetic state.
- the driving mode in the specific driving section 42 includes a braking phase 44, in which the rail vehicle 10 is braked from a first speed V 0 until a target speed V z is reached.
- the determination of the driving section 42 comprises in particular the determination of the target speed V z .
- the target velocity V z is calculated so that the kinetic energy E k i n of the rail vehicle 10 during the braking phase 44 is reduced by a kinetic amount ⁇ E k i n and Target speed V z cause a kinetic energy E kinGF and a potential energy E pot GF at the danger point 38, the sum of the energy difference .DELTA. ⁇ is smaller than the maximum permitted energy E max .
- the potential energy E pot GF at the danger point 38 depends on the target speed V z .
- the braking distance required during braking at the danger point 38 until the rail vehicle 10 stops is smaller than at a higher target speed V z .
- Rapid braking can be initiated, which would lead to a standstill at the danger point 38 at the current target speed V z is indicated by the reference BWA, which forms the beginning of a braking distance BW to the danger point 38. From this point BWA increases the potential potential energy E pot continuously up to the value E pot GF at danger point 38.
- the braking phase 44 must follow a power reduction phase 46, in which at least the current drawn by the power receiving unit 34 kinetic amount AEE k in of the content is released to the environment.
- This energy reduction phase 46 corresponds in particular to a cooling phase of brake components of the braking device 22, which are elements of the energy absorption unit 34.
- the energy dissipated by the energy intake unit 34 is called the energy reduction amount ⁇ E Q. This corresponds to the kinetic amount ⁇ E kin in this first mode.
- the target velocity V z is calculated such that less energy is dissipated as the energy reduction amount ⁇ E Q during the energy reduction phase 46 than the kinetic amount ⁇ E k i n .
- the target speed V z is calculated such that the sum of the kinetic energy E kinGF and the potential energy E pot GF at the danger point 38 is smaller than the maximum permissible vehicle energy E max by more than the energy difference ⁇ .
- the excess of energy by which the vehicle energy is reduced may still be contained in the energy intake unit 34 at the danger point 38.
- the energy reduction distance EAS can therefore be shorter than the first mode.
- the determination of the travel section 42 in the mentioned modes furthermore comprises the determination of the braking distance BS for the braking phase 44 and the energy reduction phase distance EAS for the energy reduction phase 46.
- the EAS Energyabbau- route is calculated depending on the energy reduction amount AEE Q means of a cooling performance characteristic of the power receiving unit 34th
- This cooling line characteristic can provide information about the cooling behavior of the energy absorption unit 34 or individual elements of this are taken.
- a time to reach a certain temperature reduction can be determined from the cooling performance curve.
- the energy reduction distance EAS can be calculated on this basis and with knowledge of the instantaneous speed V, normally the target speed V z .
- the braking distance 44 is calculated on the basis of the above-mentioned information BVD about the braking capacity of the rail vehicle 10 and the current speed V.
- the braking distance BS is determined on the basis of brake deceleration values BVD which are used in normal service braking.
- the braking distance BS is determined on the basis of braking deceleration values which are used in rapid braking.
- the train protection unit 28 has a remote emergency mode, in which the rail vehicle 10 is braked to a stop.
- This emergency mode is initiated when it is detected by the train control unit 28 that the brake phase 44 in the forced intervention mode is faulty - for example, with too little delay - or not executed. It is also initiated when, after the braking phase 44, the presence of an error in the energy reduction phase 46 is detected. This can eg be recognized by the fact that a temperature profile of components of the energy absorption unit 34 from one to deviates from the basis of a cooling performance curve determined temperature profile.
