Definitions
- the invention relates to a driver's cab arrangement for a rail vehicle and a method for operating a rail vehicle.
- the rail vehicle can in particular be a locomotive, a railcar or a combination of several individual rail vehicles.
- the vehicle driver (or train driver) of a rail vehicle can specify a desired driving behavior of the rail vehicle by means of a driving specification device.
- This can be a manually operable element (particularly of a mechanical nature) in a driver's cab of the rail vehicle.
- drive setting devices in the form of adjustable levers, in particular so-called driving/braking levers. These can be adjusted manually along a scale by shifting or tilting. The extent of the adjustment is detected by sensors.
- a driving behavior and in particular a value of a concretely specifiable driving behavior variable is assigned to each position of the driving specification device.
- the desired driving behavior variable specified by the driver can therefore be determined from a sensor-detected position of the driving specification device, and a drive device (in particular a traction motor) of the rail vehicle can be controlled to provide or implement this driving behavior variable.
- distance-dependent desired driving behavior profiles can be determined, in particular in the form of so-called distance/speed profiles or diagrams. These can define speeds for individual route sections that are particularly suitable for achieving a desired level of efficiency or reduced energy consumption.
- the target driving behavior profile and, in particular, suitable speeds defined thereby can be displayed to a vehicle driver, in particular visually, in the driver's cab. This is intended to encourage the driver to implement the target driving behavior by suitable actuation of the driving specification device. In other words, the driver of the vehicle is to learn from the target driving behavior profile follow specified driving behavior and manually control the rail vehicle in accordance with this profile.
- the invention provides in general for providing a drive setting device in a driver's cab arrangement which, in addition to manual actuation (in particular adjustability), can also be actuated by actuators.
- the actuation or adjustment takes place according to a target driving behavior profile.
- the target driving behavior profile can correspond to the known target profiles explained in the introduction and can in particular be a distance-speed profile.
- a preferably conventional one is provided here to actuate the driving setting device actively by a separate actuating actuator in accordance with this target driving behavior profile, in particular to deflect it.
- the actuating actuator preferably actuates the driving specification device in such a way that it assumes a position that is required to achieve a driving behavior specified by the target driving behavior profile. If this profile specifies a target speed, for example, which is preferably location-dependent, when the corresponding location is reached, the driving specification device can be actuated without manual actuation in such a way that its state and in particular its position corresponds to this target speed or this target speed is specified as a result.
- An actuation state of the driving specification device is preferably detected according to conventional approaches and/or in a manner analogous to manual actuation.
- a drive device of the rail vehicle is controlled in order to implement the driving behavior specified by the driving specification device.
- the vehicle driver can directly and purposefully change the operating state of the rail vehicle and in particular adjust its driving behavior precisely by manual intervention and in particular manual adjustment of the travel specification device. This applies in particular because a momentary position of the driving specification device that is set by an actuator corresponds to an actually specified driving behavior. A change in driving behavior desired by the driver of the vehicle can therefore be achieved intuitively by manually actuating the driving specification device.
- This solution enables a type of semi-autonomous operation of the rail vehicle and in particular of the travel specification device.
- Even in the case of an autonomous change in the driving state by means of an actuator adjustment of the driving specification device there are preferably always manual change and intervention options.
- an operating mode in which the driving specification device can be adjusted by means of actuators can (preferably exclusively) be activated and/or deactivated manually.
- there are no driver-autonomous activations of the actuator adjustment so that the vehicle cannot, for example, unexpectedly (for example not without prior manual release or activation) accelerate autonomously.
- approval requirements can be reduced compared to completely autonomous operation of the rail vehicle.
- the solution presented enables a precise implementation of a desired target driving behavior, which is characterized by safe and intuitive manual intervention options and low approval requirements.
- the solution is also characterized by a low level of adaptation effort for existing rail vehicles and, in particular, for their control architectures.
- a driver's cab arrangement for a rail vehicle is proposed, the driver's cab arrangement having:
- a driving specification device e.g. a lever or a rotary wheel which can be actuated (manually) by a vehicle driver for specifying a desired driving behavior of the rail vehicle;
- a (digital and/or electronic) memory device in which a target driving behavior profile for the rail vehicle is stored;
- an actuating actuator (herein also simply referred to as an actuator), which is set up to actuate the driving specification device in accordance with the target driving behavior profile, in particular independently of the vehicle driver;
- a drive control device which is set up to control at least one drive device of the rail vehicle in accordance with the actuations of the travel specification device.
- the memory device can be part of a control device of the rail vehicle.
- the drive control device preferably does not access the storage device directly or at least not the setpoint driving behavior profile.
- the drive control device preferably does not control the drive device of the rail vehicle directly on the basis of the target driving behavior profile, for example not by reading out or otherwise processing information from the target driving behavior profile.
- this preferably reads out actuations of the driving specification devices implemented by the actuating actuator or controls the drive devices based on corresponding actuations of the driving specification devices.
- the drive control device can use any actuation of the drive specification device to actuate the drive control device based thereon, regardless of the (actuator or manual) source or cause of the actuation.
- the drive specification device and the drive control device can be designed according to conventional approaches. This is also helpful with regard to operational safety and the associated approval requirements, since the drive control device can control the drive devices of the rail vehicle in a conventional manner on the basis of detected actuations of the travel specification device. If the drive control device, as is not preferred here, would instead receive the target driving behavior profile directly and would control drive devices of the rail vehicle on the basis of this, new safety risks would be created and an existing software or control architecture of a rail vehicle would have to be revised.
- the target driving behavior profile can specify at least one course of a desired driving behavior variable, e.g. in relation to a defined route. It is known to develop such driving behavior profiles in advance, e.g. using simulations or test drives. They can be stored as digital files and e.g. in the form of characteristic curves, tables or generally as data collections or databases in a memory device of the rail vehicle. They can also be stored in the storage device by intermediate storage and/or downloading from a vehicle-external computer device (in particular a server and also in particular an Internet server).
- a vehicle-external computer device in particular a server and also in particular an Internet server.
- the rail vehicle can be set up to determine its location, for which common solutions from the prior art can be used. It can also be set up to use the determined location to determine a target driving behavior variable defined by the target driving behavior profile. This is explained in more detail below.
- the drive control device can, for example, adapt an (electrical) power supply to the drive device.
- the drive control device in particular Control power electronics of the drive device (if this includes an electric motor) to implement a desired driving behavior.
- Forces that can be generated by the actuating actuator can be selected in such a way that they can be manually overcome by a vehicle driver, i.e. can be overridden. In other words, they can be limited in such a way that a vehicle driver can equalize or even overcome an actuation carried out by the actuation actuator with an actuation in the opposite direction. In the case of such an override, a semi-autonomous operation explained below and/or the actuating actuator can also be automatically deactivated.
- the actuating actuator when manual forces are applied to the drive specification device, the actuating actuator can also be mechanically decoupled from the latter, at least if the manual forces are above a threshold value. This can be achieved via a safety clutch that connects the actuating actuator and the driving setting device, which opens when there are appropriate forces and cancels a connection that initially transmits force and/or torque.
- an activation or a closing of such a safety clutch is required to activate an actuator-actuated operation of the driving specification device.
- the safety coupling can be closed electronically, for example, and can be activated by the driver of the vehicle by actuating a control element (for example a print head).
- a control element for example a print head
- mechanical activations are also possible.
- an actuating element mechanically coupled to the clutch can protrude into the vehicle interior and be adjustable by the vehicle driver.
- the manual intervention options and, in particular, activation options ensure that the vehicle driver can always interrupt or adjust driver-autonomous operation of the rail vehicle.
- the actuating actuator can include at least one electric motor and/or be an electric actuator. This can be mechanically connected to the driving specification device, for example via at least one connection arrangement.
- the Linkage arrangement may include, for example, a belt drive or a gear stage. In general, it preferably has the safety coupling already mentioned.
- the actuator can be set up to move the connection arrangement and thereby actuate the travel setting device.
- the actuating actuator can be set up to tilt or deflect the driving specification device, in particular in the form of a lever, via the connection arrangement.
- the driving specification device can, for example, comprise a rotary axis element or be coupled to such.
- the axis of rotation element can be rotatably mounted.
- the connection arrangement can couple the axis of rotation element and the actuating actuator to one another, for example in a force-transmitting and/or torque-transmitting manner.
- the drive control device is set up to activate the drive device independently of whether the driving specification device is actuated by the vehicle driver or by the actuating actuator.
- the drive control device cannot have knowledge of a cause or source of the operation of the travel setting device, nor can it be determined fundamentally.
- the drive control device can only receive signals about a completed actuation of the driving specification device, but not about, for example, a current operating state of the actuator or a generally set manual or semi-autonomous operating mode. At the very least, it cannot evaluate or use such information to determine the cause of the actuation of the driving specification device. Instead, the drive control device can control the drive device in the same way and based solely on the extent or the type of actuation, regardless of whether an actuation took place manually or by means of an actuator. This also ensures that no fundamental changes to existing control architectures of a rail vehicle are required, but in particular a drive control device can control drive devices of the rail vehicle in a conventional manner based on detected actuations of a driving specification device.
- the driver's cab arrangement comprises an actuation detection device which is set up to detect actuations and/or states (in particular positions) of the driving setting device and to transmit them to the drive control device.
- This can be a sensory device or, for short, a sensor.
- This can be designed according to a conventional design. It can be set up to detect a current type of actuation and in particular an extent of the actuation, for example a current position of the driving specification device. For example, this can be used to determine the extent to which a lever-like driving setting device has been tilted or a driving setting device in the form of a rotary wheel has been rotated.
- the actuation detection device can include a scale that can be moved and, in particular, tilted together with the travel specification device. It can also include a sensory unit that is set up to detect a current position of the scale. The sensory unit is preferably installed statically. The reverse case of a sensory unit that is moved together with the travel specification device with a stationary measuring standard is also possible.
- the scale and the sensory unit can generally be movable relative to one another, one of the scale and the sensory unit preferably being movable together with the travel specification device.
- one of the material measure and the sensory unit can be coupled to a rotary axis element of the type explained above.
- detected actuations or states can be transmitted to the drive control device, preferably by the actuating device itself or by another control device or communication device of the rail vehicle.
- the actuation of the driving specification device includes an adjustment or also moving of the driving specification device.
- the actuation can include tilting, displacement and/or rotation (about a horizontal, vertical or also oblique axis of rotation) of the driving specification device. This corresponds to common types of movement of a driving specification device, which are perceived as intuitive by a vehicle driver and can be reliably implemented by an actuating actuator.
- at least one of the following driving behavior parameters of the rail vehicle can be specified by means of the driving specification device:
- the target driving behavior profile preferably defines values for an identical driving behavior variable or a driving behavior variable that can be converted into the driving behavior variable that can be specified using the driving specification device.
- the actuating actuator can be connected to the drive specification device via a safety clutch or, in other words, coupled or capable of being coupled in a torque-transmitting manner.
- This connection can be made indirectly via a connection arrangement of the type described herein.
- the safety clutch can be connected to a rotary axis element of the driving setting device.
- the safety clutch can disengage, for example, when a maximum transmissible torque is exceeded, i. H. open.
- a disengagement can occur when manual forces are applied to the driving setting device, these forces resulting in a torque acting on the safety clutch.
- the safety clutch can be opened as a result of the application of manual forces to the travel setting device. This provides a reliable option that can be implemented with little mechanical effort to deactivate actuator actuations of the travel specification device or to manually override the actuation actuator. Additionally or alternatively, it can be opened using the operating element described here.
- Closing and/or opening of the safety clutch can preferably be activated manually, for example by means of the aforementioned (electronic) operating element or a mechanical actuating element.
- the closing and/or opening of the safety clutch can preferably only be activated manually, ie the safety clutch cannot disengage and/or engage automatically or independently of the driver. Otherwise there would be the possibility for driver-autonomous activations and/or Deactivation of the actuator operation and/or a corresponding one
- the target driving behavior profile defines a location-dependent target driving behavior, in particular a location-dependent target driving speed.
- location-dependent values for at least one driving behavior variable in particular of the type mentioned above, can be defined and/or specified by the profile as a corresponding target driving behavior.
- the location dependency can be established in that the corresponding values relate to specific sections of a route.
- the rail vehicle can be set up to determine its current location and/or a route section that is currently being traveled on.
- the actuating actuator can be set up (in particular a control device thereof) to determine or obtain a current value of the driving behavior variable defined by the target driving behavior profile and to actuate the driving specification device accordingly, knowing this location or route section.
- the actuating actuator is set up to actuate the driving specification device in such a way (in particular to adjust or move it in such a way) that the driving specification device assumes a position in or with which driving behavior can be specified that corresponds to the target - Driving behavior profile corresponds (in particular to a currently defined target driving behavior variable).
- the actuating actuator can be set up to adjust the driving specification device in such a way that a (current) driving behavior variable defined by the target driving behavior profile can be specified and/or implemented.
- the actuation actuator can have knowledge of the relationship between actuations and/or positions of the driving specification device and driving behavior variables that can thus be specified, for example based on calibration information.
- the actuation actuator ensures that it can precisely implement a target driving behavior profile and that an actuation and, in particular, adjustment of the driving specification device also corresponds to the actually specified driving behavior profile. This ensures precise feedback to the vehicle driver.
- the driver's cab arrangement is operable in a manual operating mode.
- the actuating actuator preferably does not actuate the driving specification device and/or is generally inactive. Any safety clutch can be open in this operating mode.
- the driver's cab arrangement can preferably also be operated in an at least partially autonomous operating mode and can preferably be switched between the manual and the partially autonomous operating mode.
- the driving specification device can be actuated by the actuating actuator, i.e. the actuating actuator can be generally active and/or a safety clutch can be closed.
- manual actuation of the actuation actuator can preferably also take place in the semi-autonomous operating mode.
- This can include the above-mentioned overriding of actuator actuations of the driving specification device, together with the preferred disengagement of an optional safety clutch.
- the change between the manual and the semi-autonomous operating mode can (preferably exclusively) be initiated by a vehicle driver, for example by him closing the safety clutch or causing him to do so.
- the invention also relates to a method for operating a rail vehicle, wherein the rail vehicle has a driving specification device which can be actuated by a vehicle driver to specify a desired driving behavior, and wherein the method has:
- the method can include all other features and developments in order to provide all the functionalities, operating states and advantages of the driver's cab arrangement described above. All explanations and developments of features of the driver's cab arrangement can also refer to the identical Procedural characteristics apply or be provided with this. In general, the method can operate a driver's cab arrangement according to any of the above aspects.
- the method can also include the steps of detecting the actuation of the driving specification device (for example by means of the actuation detection device explained above).
- the drive control device can be controlled on the basis of this detected operation.
- the method can also include the steps of determining or obtaining a target driving behavior variable currently specified by the target driving behavior profile, and actuating the driving specification device based thereon.
- the method can also include measures for selecting a manual operating mode or semi-autonomous operating mode or for switching between them.
- FIG. 1 shows a driver's cab arrangement according to an exemplary embodiment of the invention, which is operated in accordance with a method according to an exemplary embodiment.
- FIG. 1a shows a detailed view of the driver's cab arrangement from FIG. 1 in the area of a driving/braking lever.
- Fig. 2 shows a flow chart of the method from Fig. 1.
- FIG. 1 shows a highly simplified schematic view of a rail vehicle 1 . More precisely, a plan view of the rail vehicle 1 is shown, and in particular of a driver's cab 10 thereof. Essential components of the rail vehicle 1, such as the roof structure, are omitted. An outer outline of the rail vehicle 1 is shown in broken lines and is not reproduced in full here. A wheel axle 11, which is driven by an electric traction motor, is shown as a further component of the rail vehicle. The latter forms one Drive device 14. A forward travel direction F of the rail vehicle 1 is entered.
- the driver's cab 10 includes a driver's cab arrangement 12 according to an exemplary embodiment of the invention.
- the driver's cab arrangement 12 initially includes a driving setting device in the form of a lever 18. This is shown in plan view so that only its circular outline can be seen.
- the lever 18 is movable in a slot 19. More precisely, it can be actuated in such a way that it can be displaced or tilted along the slot 19 . Such a movement corresponds to an adjustment of the lever 18. Further details of the lever 18 can be found in FIG. 1A discussed below.
- Positions assumed by the lever 18 can be detected by an actuation detection device 20 . As indicated by dashed lines, this is connected in a data-transmitting manner to a drive control device 22 in the form of a control device, which comprises at least one processor device (not shown separately). Activations detected by the activation detection device 20 and in particular current positions of the lever 18 are thereby transmitted to the drive control device 22 .
- a zero position of the lever 18 marked 0 along the movement slot 19 is shown by way of example. If the lever 18 assumes this position, it predetermines a driving speed of 0 km/h. Shifts in the forward driving direction F correspond to the specification of an increasing positive driving speed, with each corresponding position of the lever 18 being assigned a concrete, specified driving speed value. Shifts against the forward direction F correspond to the specification of a deceleration or a negative acceleration.
- the actuation detection device 20 or the drive control device 22 can determine a driving behavior currently specified by means of the lever 18 and more precisely in other words, a driving behavior variable currently specified by this in the form of the driving speed and/or any negative acceleration.
- the drive control device 22 is set up to control the drive device or the traction motor 14 based on this, for example via a data connection indicated by dashed lines, so that it implements the specified driving behavior variable by suitably driving the wheel axle 11 .
- the driver's cab arrangement 12 also includes an actuating actuator 24.
- this is an electric motor. It is mechanically coupled to the lever 18 via a connection arrangement 26 indicated schematically. More precisely, the coupling takes place in such a way that the actuating actuator 24, also simply referred to as an actuator or motor below, can move or adjust the lever 18 along the slot 19 by means of force and/or torque transmission by means of the connection arrangement 26.
- the connection arrangement 26 is only optional and a direct mechanical coupling of the actuator 24 and the lever 18 could also be provided.
- a safety clutch 80 is preferably provided in order to selectively mechanically couple or decouple the actuator 24 and the lever 18 to one another.
- the actuator 24 is connected to an actuator control device 26 in a data-transmitting manner.
- This has at least one processor device 28 .
- at least one memory device 30 is provided.
- a desired driving behavior profile is stored in memory device 30, for example in the form of a characteristic curve, a general data set or a data table. This storage can be done by a vehicle manufacturer, e.g. subsequently, e.g. as part of development work or software updates or in preparation for a specific ferry operation, e.g. by downloading the target driving behavior profile from a computer device external to the vehicle (e.g. using a mobile phone or Internet connection).
- the actuator control device 26 is generally set up to control the actuating actuator 24 in such a way that it moves or adjusts the lever 18 in a desired manner.
- the rail vehicle 1 for example, a separate control device not shown or the actuator control device 26 itself
- a driving behavior variable (in the exemplary case shown, the driving speed) specified by the target driving behavior profile is then determined for this location or for this route section. This can also be done by the actuator control device 26 and in particular its processor device 28 .
- a relationship between a position of the lever 18 to be assumed, so that the correspondingly determined driving behavior variable can thereby be predetermined or so that it assumes a position along the slot 19 that corresponds to a corresponding predetermined size, can also be stored in advance (in particular in the memory device 30).
- Such a relationship can be determined, for example, by calculation or by calibration.
- the actuator control device 26 knows which position the lever 18 has to assume in order to specify the driving behavior variable that is currently desired according to the target driving behavior profile, and can control the actuating actuator 24 accordingly.
- the connection between an actuator actuation and the position of the lever 18 that can be implemented or achieved with it can also be known and can be determined in advance, for example.
- FIG. 1a A detailed view in the area of the lever 18 is shown in FIG. 1a.
- the view again corresponds to a top view analogous to FIG. 1, although some components that are covered by the control panel 15 from the vehicle driver's perspective are shown for reasons of explanation.
- the representation is again schematic and can therefore deviate in detail from the positioning of individual components shown in FIG.
- the lever 18 and the slot 19 shown in broken lines can be seen.
- the lever 18 is moved or inclined into a forward-pointing position.
- the lever 18 has a rod 17 via which it is connected to a pivot element 82 .
- the axis of rotation element 82 is movably mounted via pivot bearings, which are not shown separately.
- the axis of rotation R runs in the plane of the drawing and along the axis of rotation element 82 .
- a position of the actuation detection device 20 is also indicated, which can generally be embodied as a sensor for detecting a rotary movement and/or angular position of the rotary axis element 82 .
- the axis of rotation element 82 can optionally also be detected by other sensory units in a manner known per se. This is used in common control architectures to query so-called safety signals. However, since the rotary axis element 82 in the present case remains largely unchanged compared to existing solutions, these safety signals can still be tapped and the control architecture of the rail vehicle 1 can therefore remain essentially unchanged.
- a safety coupling 80 is shown as an example at one end of the rotary axis element 82 .
- This can be designed according to known solutions.
- a first, for example, ring-shaped part 81 of the safety coupling 80 is coupled to the rotational axis element 82 in a torsionally rigid manner.
- a second, for example, ring-shaped part 83 is connected to the connection arrangement 26 in a torsionally rigid manner.
- the parts 81, 83 can be connected in a torque-transmitting manner (engaged state) or detached from one another (disengaged state without torque transmission) via a clutch mechanism that is not shown separately.
- the clutch mechanism or, in general, the safety clutch 80 can be actuated electronically, with the actuation being able to be carried out manually by the vehicle driver via a control element on the driver's desk 15 that is not shown separately.
- the safety coupling 80 can also be understood as a component of the connection arrangement 26 .
- the connection arrangement 26 has, for example, a first belt pulley 86 which is shown in section and which can optionally be of hollow-cylindrical design (shown here with an optionally closed bottom) around the axis of rotation R.
- the belt pulley 86 is connected to the second part 83 of the safety clutch 80 in a torsionally rigid manner.
- the pulley 86 is connected to a driven wheel 25 of the actuator 24, which also serves as a pulley, via a belt 84 indicated by broken lines.
- the belt 84 runs over the pulley 86 and the driven wheel 25, so that in the top view of Figure 1 only a portion or only about half the length of the Belt 84 can be seen (in particular only its upper peripheral portion).
- a further section or a further half is covered by the section shown.
- the axis of rotation R is surrounded by the belt 84 or the belt 84 runs around the axis of rotation R by looping around the belt pulley 86 and the driven wheel 25.
- Safety clutch 80 is preferably only engaged again in response to a corresponding request by the driver of the vehicle, for example by actuating the control element, which is not shown. This enables a change to a semi-autonomous operating mode.
- the safety clutch 80 is preferably positioned between the actuating actuator 24 and an element detected by the actuation detection device 20 (here by way of example: rotary axis element 82). This positioning can relate in particular to a position in the power flow between the actuator 24 and the lever 18 . This makes it possible for 80 lever operations to be reliably detected even when the safety clutch is open.
- the driver's cab arrangement 12 there are different modes of operation of the driver's cab arrangement 12 to choose from, between which a train driver can preferably switch manually.
- the actuating actuator 24 is inactive in such a way that it does not make any adjustments to the driving lever 18 (in particular because the safety clutch 80 is open).
- the drive lever 18 is then adjusted purely manually, which is detected by the actuation detection device 20 and is the basis for an activation of the traction motor 14 by the drive control device 22 .
- the lever 18 can be controlled and, more precisely, moved by the actuating actuator 24 according to the target driving behavior defined by the target driving behavior profile (in particular due to the closed safety clutch 80).
- the target driving behavior profile in particular due to the closed safety clutch 80.
- an operator receives immediate visual feedback in the form of the current position or movement of the lever 18, which driving behavior is currently specified. If he wishes to deviate from this, he can intuitively move the lever 18 in an appropriate manner, with the position set by the actuator forming an easily understandable reference. If a corresponding adjustment has been made, the actuator 24 can then move the latter back into a position corresponding to the desired driving behavior in the absence of manual actuation and in the knowledge of a position of the lever 18 currently detected, e.g. by the actuation detection device 20.
- a data-transmitting connection (not shown in FIG. 1 ) can also be present between the actuation detection device 20 and the actuator control device 26 .
- the semi-autonomous operating mode enables the desired target driving behavior to be implemented precisely, since the operation is controlled by the actuator control device 26 with computer support.
- previous manual delays in the implementation of a desired target driving behavior that is only displayed visually can be avoided.
- a preferred variant provides for manual intervention (ie manual adjustment) of the lever 18 in the semi-autonomous operating mode to automatically switch to the manual operating mode, ie the semi-autonomous operating mode is specifically interrupted and ended. As shown, this can be done in particular by opening a Safety clutch 80 take place after reaching a force and / or torque limit. This can prevent driver-autonomous interventions from taking place again unnaturally quickly from the driver's point of view. Control of driving behavior can be left with the driver until he activates semi-autonomous operation again. Driver-independent automatic activation of the semi-autonomous operating mode, on the other hand, could be accompanied by increased approval requirements.
- FIG. 2 shows a flow chart of an exemplary method which can be executed by the driver's cab arrangement 12 from FIG. 1 or according to which the rail vehicle 1 shown there can be operated.
- a semi-autonomous operating mode of the type described above is activated.
- the actuator control device 26 receives information relating to the current location or route section traveled by the rail vehicle 1 or determines this information itself is specified and defined by the target driving behavior profile stored in memory device 30 .
- a current position of the lever 18 is then preferably checked. This can be done by means of the actuation detection device 20 and information determined therefrom. If this position of the lever 18 corresponds to a desired setpoint driving behavior or if the setpoint driving behavior variable determined in step S3 can be specified as a result, the actuating actuator 24 cannot initially be activated separately. Instead, for example, a new target driving behavior variable can be determined at regular intervals or when determining/obtaining a new location or route section, and the lever position can be checked again (see dashed returning arrow at S3).
- the actuator control device 26 controls the actuating actuator 24 in step S4 in such a way that it moves the lever 18 into a position corresponding to the determined setpoint driving behavior variable.
- This movement of the lever 18 is in turn detected by the actuating device 20 in step S5.
- Actuating device 20 transmits the detected actuation and in particular a currently assumed position of lever 18 to drive control device 22 in step S6.
- this operating mode can be ended as soon as the driver opens the safety clutch 80 by applying a manual force and then actuates the lever 18 purely manually.
- a change to a manual operating mode can also take place by opening the safety clutch 80 by actuating an operating element on the driver's desk 15 (not shown).
