Definitions

  • the present invention relates to a vehicle, in particular a rail vehicle, having a wagon body, in particular a double deck wagon body, a first running gear, a second running gear arranged at a distance from the first running gear in a vehicle longitudinal direction, in particular, trailing the first running gear, a side wind compensation device and, in particular, a rolling compensation arrangement.
  • the wagon body is supported on the first running gear and the second running gear in a vehicle height direction by means of spring devices.
  • the side wind compensation device comprises a control device and an active device acting between the wagon body and the first running gear and/or the second running gear and controlled by the control device to at least reduce side wind induced wheel unloading at the first running gear caused by a side wind load acting on the wagon body.
  • the present invention also concerns a method for setting rolling angles on a wagon body of a vehicle.
  • the wagon body On rail vehicles - but also on other vehicles - the wagon body is generally supported on the wheel units, for example wheel pairs and wheelsets, via one or more spring stages.
  • the centrifugal acceleration generated transversely to the direction of motion and thus to the vehicle longitudinal axis means that as a result of the comparatively high position of the center of gravity of the wagon body the wagon body has a tendency to roll towards the outside of the curve in relation to the wheel units thus causing a rolling motion about a rolling axis parallel to the vehicle longitudinal axis.
  • rolling motions detract from the travel comfort when they exceed certain limiting values. In addition they also constitute a danger of breaching the permissible gauge profile and, in terms of the tilt stability and thus also the derailment safety, a danger of inadmissible unilateral wheel unloading.
  • rolling support mechanisms in the form of so-called rolling stabilisers are used.
  • the task of these rolling support mechanisms as known, for example, from EP 1 075 407 B1 is to offer a resistance to the rolling motion of the wagon body in order to reduce the latter, but at the same time not hindering the rising and dipping motion of the wagon body in relation to the wheel units.
  • a specific embodiment of such rolling stabilisers is used in rail vehicles, such as those known from EP 1 190 925 A1 .
  • the upper ends of the two rods of the rolling stabilisers (in a plane running perpendicularly to the vehicle longitudinal axis) are displaced towards the center of the vehicle.
  • the wagon body in the event of a deflection in the vehicle transverse direction (as is caused, for example, by the centrifugal acceleration during travel in curves) is guided in such a way that a rolling motion of the wagon body toward the outside of the curve is counteracted and a rolling motion directed toward the inside of the curve is imposed upon it.
  • This rolling motion in the opposite direction serves, inter alia, to increase the so-called tilting comfort for the passengers in the vehicle.
  • a high tilting comfort is normally understood here to be the fact that, during travel in curves, the passengers experience the lowest possible transverse acceleration in the transverse direction of their reference system, which as a rule is defined by the fixtures of the wagon body (floor, walls, seats, etc.).
  • the fixtures of the wagon body floor, walls, seats, etc.
  • the passengers (depending on the degree of tilting) experience at least part of the transverse acceleration actually acting in the earth-fixed reference system merely as increased acceleration in the direction of the vehicle floor, which as a rule is perceived as less annoying or uncomfortable.
  • the rolling motion matched to the bend of the curve currently being travelled and the current running speed (and consequently also the resultant transverse acceleration) on the vehicle from EP 1 190 925 A1 can also be influenced or set actively by an actuator connected between the wagon body and the running gear frame.
  • an actuator connected between the wagon body and the running gear frame.
  • a setpoint value is calculated for the rolling angle of the wagon body, which is then used for setting the rolling angle by means of the actuator.
  • a further problem in connection with the use of such rolling support mechanisms is the sensitivity of the vehicle to side winds.
  • the effective point of application of which in the direction of travel
  • the center of gravity which is typically located in the longitudinal center of the wagon body.
  • This force action caused by side wind brings about a so-called yaw motion of the wagon body (thus a rotation of the wagon body about its height axis), wherein the forward part of the wagon body is deflected by the side wind, while the trailing part is rotated against the side wind. The deflection continues until the restoring forces of the support of the wagon body on the running gears balance out the yaw moment caused by the side wind load.
  • Certain train network operators such as e.g. Deutsche Bahn, issue side wind guidelines providing specific side wind scenarios and upper limits for maximum wheel unloading under these side wind scenarios to be respected by vehicles to be admitted for operation.
  • the control system known from WO 2010/113045 A2 uses several vehicle mounted sensors, e.g. displacement sensors, typically available in modern rail vehicles.
  • the problem of providing appropriate reaction is however aggravated here by the fact that the detection variables captured by these sensors are not only affected by the side wind load but also (typically primarily) by the track condition of the track currently used.
  • providing appropriate side wind reaction first of all requires properly distinguishing side wind induced effects from track condition induced effects, which, in turn, requires data analysis typically increasing reaction times.
  • the object for the present invention was therefore to provide a vehicle or a method of the type mentioned initially, which does not or at least to a lesser degree have the disadvantages mentioned above and which, in particular, in a simple and reliable manner allows a obtaining a reduced sensitivity of the vehicle to side wind.
  • the present invention solves this problem on the basis of a vehicle according to the preamble of claim 1 by means of the features indicated in the characterizing part of claim 1. It also solves this problem on the basis of a method according to the preamble of claim 11 by means of the features indicated in the characterizing part of claim 11 .
  • the present invention is based on the technical teaching that, in a simple and reliable manner, a reduced sensitivity to side wind or an increase in the permissible speed of the vehicle can be achieved despite the use of rolling compensation devices, if the control of the active device uses two separate control modes, a base wind control mode and a selectively activatable gust wind control mode, performing side wind reaction control on the basis of different input variable sets or input variable groups, respectively.
  • the use of different input variable sets or input variable groups has the advantage that a respective control mode tailored to the different frequency ranges of the base side wind load and the gust side wind load may be achieved which allows, in particular, sufficiently rapid generation of control information in the time critical gust wind control mode.
  • the present invention is based on the cognition that, nonetheless due to the inertia of the vehicle components, the damping properties of their mutual mechanical connections and the specific side wind flow impact conditions at a vehicle running at high speeds, the higher frequency loads of the gust side wind component mainly affect certain vehicle state variables, in particular, certain motion state variables, of vehicle components in the area of the leading running gear, while having a negligible effect on these vehicle state variables in the area of the trailing running gear.
  • the lower frequency base side wind component of the side wind load due to its generally quasi-stationary nature, leads to side wind characteristic patterns in certain vehicle state variables, in particular, certain motion state variables, of vehicle components in the area of both running gears.
  • the present invention allows using the set of state variable sensors conventionally present in modern rail vehicles while at the same time providing appropriately rapid control and low reaction times, respectively, necessary to keep side wind related wheel unloading at the running gears within certain limits.
  • the present invention allows shifting or distributing, respectively, the wheel unloading effects between the two running gears. More precisely, with the present invention, among others, side wind induced wheel unloading may be actively shifted in a beneficial way from the typically more affected or more side wind sensitive leading running gear to the less affected or less side wind sensitive trailing running gear. While this shift obviously increases the wheel unloading at the trailing running gear it nevertheless allows respecting maximum wheel unloading limits at all wheels of both running gears.
  • the present invention therefore relates to a vehicle, in particular a rail vehicle, comprising a wagon body, in particular a double deck wagon body, a first running gear, a second running gear arranged at a distance from the first running gear in a vehicle longitudinal direction, in particular, trailing the first running gear, a side wind compensation device and, in particular, a rolling compensation arrangement.
  • the wagon body is supported on the first running gear and the second running gear in a vehicle height direction by means of spring devices.
  • the side wind compensation device comprises a control device and an active acting between the wagon body and the first running gear and/or the second running gear device and controlled by the control device to at least reduce side wind induced wheel unloading at the first running gear caused by a side wind load acting on the wagon body.
  • the side wind compensation device has a base wind control mode and a selectively activatable gust wind control mode.
  • the side wind compensation device is configured to control, in the base side wind control mode and as a function of a first input variable group, a first magnitude of a first action of the active device counteracting a first wheel unloading component resulting from a base wind load component acting on the wagon body in a first wind control frequency range.
  • the side wind compensation device is configured to control, in the activated gust side wind control mode and as a function of a second input variable group, a second magnitude of a second action of the active device counteracting a second wheel unloading component resulting from a gust wind load component acting on the wagon body in a second wind control frequency range.
  • the first input variable group differing from the second input variable group in at least one input variable.
  • the controlling of second magnitude in the once activated gust side wind control mode shall be understood as varying the magnitude of a non-zero second action of the active device up to a predeterminable maximum value as an exclusive function of the second input variable group.
  • general activation and deactivation (or switching on and off) of the gust side wind control mode as well as predetermining the maximum value may eventually also be triggered or executed as a function of the first input variable group.
  • the respective input variable group may eventually consist of one single input variable.
  • arbitrary input variables allowing sufficiently differentiated conclusions on the current magnitude and/or direction and/or point of attack of the base side wind component and the gust side wind component may be used for the respective input variable group.
  • the first input variable group used in the base wind control mode comprises at least a first input variable and a second input variable
  • the second input variable group used in the gust wind control mode comprises at least the first input variable and, in particular, excludes the second input variable.
  • the first input variable preferably is representative of a motion status of a first component of the vehicle located in the area of the first running gear
  • the second input variable is representative of a motion status of a second component of the vehicle located in the area of the second running gear.
  • the first and/or second component may be any suitable component located in the area of the respective running gear and undergoing appropriate motion in response to side wind.
  • the first and/or second component may be a component of the respective running gear or a component of the wagon body or a component of the rolling compensation arrangement.
  • the first input variable is a first rolling rate variable representative of a first rolling rate of a rolling motion of a component, in particular, a running gear frame, of the first running gear about a first running gear rolling axis parallel to a first running gear longitudinal direction of the first running gear.
  • the second input variable may be a second rolling rate variable representative of a second rolling rate of a rolling motion of a component, in particular, a running gear frame, of the second running gear about a second running gear rolling axis parallel to a second running gear longitudinal direction of the second running gear.
  • the higher frequency loads of the gust side wind component mainly affect the first rolling rate at the leading running gear, while having a negligible effect on the second rolling rate at the trailing running gear.
  • the lower frequency base side wind component of the side wind load due to its generally quasi-stationary nature, leads to side wind characteristic patterns in both the first rolling rate at the leading running gear and the second rolling rate at the trailing running gear.
  • proper and rapid reaction is preferably based on the value of the first rolling rate at the leading running gear, while neglecting the second rolling rate at the trailing running gear. This greatly speeds up data processing and generation of corresponding control information, respectively.
  • proper and sufficiently rapid reaction is preferably based on the value of the first rolling rate at the leading running gear and the second rolling rate at the trailing running gear.
  • the second wind control frequency range at least partially lies above the first wind control frequency range, the first wind control frequency range, in particular, ranging from essentially 0 Hz to 2 Hz, preferably from essentially 0 Hz to 1.5 Hz, the second wind control frequency range, in particular, ranging from 0.25 Hz to 5 Hz, preferably from 0.25 Hz to 2.5 Hz.
  • the first wind control frequency range in particular, ranging from essentially 0 Hz to 2 Hz, preferably from essentially 0 Hz to 1.5 Hz
  • the second wind control frequency range in particular, ranging from 0.25 Hz to 5 Hz, preferably from 0.25 Hz to 2.5 Hz.
  • the side wind compensation device is configured to determine, in the base side wind control mode, a base side wind rolling angle difference information representative of a base side wind induced rolling angle difference between the first component and the second component using the input variables of the first input variable group.
  • the side wind compensation device is further configured to generate, in the base side wind control mode, base control information for the active device as a function of the base side wind rolling angle difference information previously determined.
  • the rolling angle difference thus determined is a particularly favorable and reliable indicator of the presence of base side wind effects since the quasi-stationary load component of the base side wind component generates a quasi-permanent side wind induced yaw deflection of the wagon body about a yaw axis parallel to the vehicle height direction.
  • the instantaneous yaw axis in the vehicle longitudinal direction typically is located closer to the trailing running gear, such that it results in non-uniform lateral deflections of the first and second spring devices characteristic for the specific vehicle under side wind load.
  • the rolling angle difference information may be obtained in any suitable way as a function of the input variables available.
  • the side wind compensation device is configured to generate the base side wind rolling angle difference information using integration over time of a difference between the first rolling rate variable and the second rolling rate variable.
  • the respective rolling rate variable may be obtained in a conventional manner, e.g. using the signals of a gyroscope sensor mounted to the respective running gear.
  • the side wind compensation device is configured to generate the base control information by inputting the base side wind rolling angle difference information into an integrating controller (I-controller).
  • I-controller an integrating controller
  • the use of such an integrating controller has the advantage that it is comparatively inert adding to overall stability of the base side wind part of the control system.
  • any other suitable type of controller may be used.
  • appropriately configured PI controllers as well as P controllers, in particular P controllers with a delaying component or P controllers with backlash, may be used.
  • the side wind compensation device is configured to take into account travel of the vehicle on a twisted track section, in particular, on a curve transition track section between a straight track section and a constantly curved track section, and has a twisted track mode modifying the base control information to at least reduce action of the active device during travel in the twisted track section.
  • Such a reduction may be achieved, for example, by delaying the signal of the leading running gear as a function of the actual running speed of the vehicle and the longitudinal distance between the running gears, such that the delayed leading running gear signal and the non-delayed trailing running gear signal, which are then further processed together, have been taken at least approximately at the same location on the track, thereby reducing track twist induced errors in the base side wind control.
  • this signal delaying in turn only has a negligible effect of the reaction to base side wind effects. This is due to the fact that, at the relevant high vehicle running speeds necessitating side wind control, the period of the low frequency base side wind component is way larger than the delay introduced into the leading running gear signal.
  • the leading signal instead of delaying the leading signal it may also be chosen to advance the trailing signal by similar means.
  • the side wind compensation device is configured to generate, in the gust side wind control mode, gust control information for the active device as a function of the input variables of the second input variable group, in particular, as a function of the first input variable, in particular, as a function of the first rolling rate variable.
  • the side wind compensation device is further configured to overlay, in particular, add, in the gust side wind control mode, the gust control information to a base control information to generate total control information to be used for controlling the active device.
  • Control information overlay may be obtained in any suitable linear or non-linear way.
  • the base control information generates a base action at the active device and the gust control information generates a gust action at the active device, wherein the overlay is the simple sum of both actions.
  • the gust control information may generally ensue in any suitable way as a function of the input variable or variables used and their relation to the gust side wind effect.
  • the gust control information generates a gust action at the at least one active device that is substantially proportional to the first input variable, in particular, substantially proportional to the first rolling rate.
  • the side wind compensation device is configured to limit an absolute value of the gust control information to a predeterminable upper limit. This has the advantage to avoid critical overreactions which might otherwise lead to excess wheel unloading at the trailing running gear.
  • the side wind compensation device is preferably configured to activate the gust side wind control mode only if the base control information exceeds a predeterminable threshold value representative of a predeterminable level of action of the active device, i.e. representative of a certain noticeable amount of base side wind.
  • the side wind compensation device may be configured to activate the gust side wind control mode only if the base action and the gust action have the same sense of action.
  • the side wind compensation device is configured to activate the gust side wind control mode only if the first rolling rate lies within a tolerance band defined as a function of the first rolling rate and the second rolling rate. This avoids overreactions and increases overall stability of the side wind control. Similar applies to further variants where the side wind compensation device is configured to detect travel of the vehicle on a twisted track section, and is further configured to activate the gust side wind control mode only if travel outside a twisted track section is detected.
  • the control device has a control component controlling the rolling compensation arrangement in a comfort control mode to set a transverse deflection of the wagon body with respect to the first running gear and/or the second running gear, e.g. in order to compensate the undesired effects of lateral track irregularities.
  • the control component is set to a maximum damping mode if the gust side wind control mode is activated, in particular, if the base control information exceeds the predeterminable threshold value representative of the predeterminable level of action of the active device.
  • the rolling compensation arrangement in the maximum damping mode, provides maximum damping of a yaw motion of the wagon body about a yaw axis running parallel to vehicle height direction. This avoids that (generally possible) conflicting actions of the side wind control and the comfort control lead to control system instabilities.
  • the action of the active device may basically be of any desired type suitable to reduce the wheel unloading effects induced by the side wind load.
  • the active device is configured to counteract a side wind induced yaw motion of the wagon body about a yaw axis parallel to a vehicle height direction.
  • the active device may comprise a first actuator acting between the first running gear and the wagon body and/or a second actuator acting between the second running gear and the wagon body.
  • an active component e.g. a linear actuator or a rotational actuator
  • the use of an active component in the area of just one of the two running gears or rolling compensation devices, respectively, may be sufficient.
  • an active component e.g. a linear actuator or a rotational actuator
  • the yaw moment on the vehicle body resulting from the side wind load can be counteracted in that the deflection of the wagon body is counteracted by a corresponding force action in the area of the forward running gear, e.g. in the area of its rolling compensation device, while the deflection is not actively counteracted at the trailing running gear.
  • control unit uses total control information to control a first actuator and a second actuator of the active device to generate a first yaw moment and a concurrent, in particular substantially identical, second yaw moment acting on the wagon body to counteract a side wind induced yaw moment acting on the wagon body.
  • the wagon body is coupled to the first running gear by means of a first rolling compensation device of the rolling compensation arrangement, while the wagon body is coupled to the second running gear by means of a second rolling compensation device of the rolling compensation arrangement.

  • the first rolling compensation device comprises the first actuator device at least contributing to a setting of the first transverse deflection.
  • the second rolling compensation device may comprise the second actuator device at least contributing to a setting of the second transverse deflection.
  • the rolling compensation arrangement may be configured to set, under the control of the control device and in a comfort control mode, the first transverse deflection and/or the second transverse deflection.
  • the first rolling compensation device has a first actuator device of the active device with at least one first actuator unit controlled by the control device.
  • the first actuator device is preferably configured to contribute, controlled by the control device, to the setting of the first transverse deflection in order to at least reduce the deviation between the first transverse deflection and the second transverse deflection and/or the deviation between the first wagon body rolling angle and the second wagon body rolling angle.

  • Relevant influencing variables here include the torsional stiffness of the wagon body about the vehicle longitudinal axis and the distance between the two running gears in the direction of the vehicle longitudinal axis. The stiffer the wagon body or the smaller the distance between the two running gears, the smaller the deviation must be between the transverse deflections or the rolling angles in order to achieve a specified reduction in the torsional load on the wagon body and the wheel unloading, respectively.
  • the control device controls the first actuator unit and/or the second actuator unit according to the detection variable in such a way that the deviation between the first transverse deflection and the second transverse deflection is less than 40 mm, preferably less than 25 mm, further preferably less than 10 mm.
  • the control device can control the first actuator unit and/or the second actuator unit as a function of the detection variable in such a way that a deviation between a first rolling angle of the wagon body in relation to the first running gear and a second rolling angle of the wagon body in relation to the second running gear is less than 2°, preferably less than 1°, further preferably less than 0.5°.
  • the control device controls the first actuator unit and/or the second actuator unit according to the detection variable in such a way that the deviation between the first transverse deflection and the second transverse deflection is less than 40 mm, preferably less than 25 mm, further preferably less than 10 mm.
  • the control device can control the first actuator unit and/or the second actuator unit as a function of the detection
  • the input variables may be done in any suitable way.

  • the second input variable may be a second rolling rate variable representative of a second rolling rate of a rolling motion of a component, in particular, a running gear frame, of the second running gear about a second running gear rolling axis parallel to a second running gear longitudinal direction of the second running gear.
  • the side wind compensation device may generally be constantly active.
  • the side wind compensation device is only active under side wind critical operating conditions, in order to largely avoid interference with other control functions, such as tilt control and comfort control.
  • the side wind compensation device is only activated if a running speed of the vehicle exceeds a side wind control activation threshold, said side wind control activation threshold, in particular, being 120 km/h, preferably 140 km/h, more preferably 160 km/h.

  • the second running gear comprises a second primary spring device, the second primary spring device having a second rigidity in the vehicle height direction
  • the first rigidity is selected to be different from, in particular lower than, the second rigidity.
  • a track feedback control mode is implemented which at least partially compensates influences introduced into the vehicle via the track currently travelled on.
  • the first rolling compensation device in order to increase the tilting comfort, is designed to impose upon the wagon body, in a first track control frequency range and under a first transverse deflection of the wagon body in the direction of the vehicle longitudinal axis, a first wagon body rolling angle component of the first wagon body rolling angle, which corresponds to a current curvature of a current section of track being travelled.
  • the first rolling compensation device can be designed to impose upon the wagon body in a second track control frequency range, which at least partially lies above the first track control frequency range, a second transverse deflection component (as the case may be, therefore, also a second wagon body rolling angle component about the wagon body rolling axis).
  • the transverse deflection component resulting from the first wagon body rolling angle component the setting of which ultimately represents a quasi-static adaptation of the wagon body rolling angle and thus the transverse deflection to the current track curvature and the current speed, can be overlaid with a second transverse deflection component (as the case may be, therefore, also a second wagon body rolling angle component), the setting of which ultimately represents a dynamic adaptation to current disturbances introduced into the wagon body.
  • the rolling compensation device as an active system in at least the second track control frequency range, in an advantageous manner it is possible to design the support of the wagon body on the running gear in the transverse direction of the vehicle to be comparatively stiff, in particular to position the wagon body rolling axis or the instantaneous center of rotation of the wagon body comparatively close to the center of gravity of the wagon body, so that firstly the desired wagon body rolling angle is associated with relatively low transverse deflections and secondly in the event of a failure of the active components the most passive possible restoration of the wagon body to a neutral position is possible.

  • this allows a high level of functional integration and/or a very compact design to be achieved, which is a particular advantage, in particular with regard to the limited space available in modern running gears.
  • the second rolling compensation device can also have a different design from the first rolling compensation device.
  • the first rolling compensation device and the second rolling compensation device are substantially of the same design, so that the statements made herein concerning the features, functions and advantages of the first rolling compensation device can equally be made in relation to the second rolling compensation device.
  • the second transverse deflection component does not necessarily have to be associated with a second wagon body rolling angle component corresponding to the (static) kinematics of the first rolling compensation device, which is overlaid on the first rolling angle component in the second track control frequency range.
  • the first wagon body rolling angle component in a design with a rigid coupling to an inherently rigid rolling compensation device, in the second track control frequency range is ultimately overlaid by a second rolling angle component.

  • the sensor unit 107.4 on the first bogie frame 104.2 provides, as a first input variable for the controller 107.2 a first rolling rate variable RRVB1 representative of a first rolling rate RRB1 of a rolling motion of the first bogie frame 104.2 about a first bogie rolling axis parallel to a first bogie longitudinal direction (x f ) of the first bogie 104 (i.e. an input variable that is representative of the motion status of the bogie frame 104.2 as a first component of the vehicle 101 located in the area of the first running gear 104).
  • the sensor unit 107.4 on the second bogie frame 114.2 provides, as a second input variable for the controller 107.2 a second rolling rate variable RRVB2 representative of a second rolling rate RRB2 of a rolling motion of the second bogie frame 114.2 about a second bogie rolling axis parallel to a second bogie longitudinal direction (x f ) of the second bogie 114 (i.e. an input variable that is representative of the motion status of the bogie frame 114.2 as a second component of the vehicle 101 located in the area of the second running gear 114).
  • the side wind compensation device 118 comprises a base side wind control part 118.1 of controller 117.2, which, in the base wind control mode BWCM, determines a base wind rolling angle difference information BWRADI representative of a (base side wind load component BSWL induced) rolling angle difference RAD between the leading bogie frame 104.3 and the trailing bogie frame 114.3 using the input variables of a first input variable group IVG1.
  • the first input variable group IVG1 comprises the rolling rate variable RRVB1 of the leading bogie frame 104.2 and the rolling rate variable RRVB2 of the trailing bogie frame 114.2.
  • the base side wind control part 118.1 then generates base wind control information BWCI for the actuators 107.1, 117.1 as a function of the base wind rolling angle difference information BWRADI previously determined.
  • the rolling angle difference RAD thus determined is a particularly favorable and reliable indicator of the presence of base side wind effects, since the quasi-stationary load component of the base side wind load component BSWL generates a quasi-permanent side wind induced angular yaw deflection ⁇ yaw of the wagon body 102 about its yaw axis.
  • the instantaneous yaw axis in the vehicle longitudinal direction typically is located closer to the trailing bogie 114, such that it results in non-uniform lateral deflections of the first and second spring devices 103 characteristic for the specific vehicle 101 under side wind load SWL.
  • the side wind compensation device 118 has a twisted track mode TTM modifying the base wind control information BWCI to reduce action of the actuators 107.1, 117.1 during travel in the twisted track section.
  • the reduction is achieved in the present example by delaying the signal of the first rolling rate variable RRVB1 in a delaying controller part 118.2 as a function of the actual running speed V of the vehicle and the longitudinal distance D between the bogies 104, 114, such that the delayed leading running gear signal RRVB1 and the non-delayed trailing running gear signal RRVB2, which are then further processed together, have been taken at least approximately at the same location on the track, thereby reducing track twist induced errors in the base wind control mode BWCM.
  • this signal delaying action in turn only has at most a negligible effect of the reaction to base side wind effects. This is due to the fact that, at the relevant high vehicle running speeds V necessitating side wind control, the period of the low frequency base side wind load component BSWL is way larger than the delay introduced into the leading running gear signal RRVB1.
  • the base side wind controller part 118.1 then generates the base wind rolling angle difference information BWRADI using integration over time of a difference between the first rolling rate variable RRVB1 and the second rolling rate variable RRVB2 in an integrator 118.3.
  • the side wind compensation device 118 generates the base wind control information BWCI by inputting the base wind rolling angle difference information BWRADI into an integrating controller 118.4 (I-controller).
  • an integrating controller 118.4 I-controller.
  • the use of such an integrating controller 118.4 has the advantage that it is comparatively inert adding to overall stability of the base side wind controller part 118.1 of the control system.
  • gust wind control GWC is achieved in the present example in the gust wind control mode GWCM using a gust side wind controller part 118.5 of controller 117.2.
  • the gust side wind controller part 118.5 in case of activation of the gust side wind control mode GWCM, generates gust wind control information GWCI for the actuators 107.1, 117.1 as a function of the input variable of a second input variable group IVG2 exclusively formed by the first rolling rate variable RRVB1.
  • the gust wind control information GWCI is generated in a preferred and highly dynamic way in that it is simply output at the gust controller part 118.5 as signals that are substantially proportional to the first rolling rate variable RRVB1 of the leading bogie 104.
  • the side wind compensation device 118 has a limiter control part 118.6 limiting an absolute value of the gust wind control information GWCI to a predeterminable upper limit. This has the advantage to avoid critical overreactions which might otherwise lead to excess wheel unloading at the trailing bogie 114.
  • the side wind compensation device 118 is further configured to overlay, in the gust wind control mode GWCM, the gust wind control information GWCI to the base wind control information BWCI to generate total wind control information TWCI to be used for controlling the actuators 107.1, 117.1.
  • the base wind control information BWCI and the gust wind control information GWCI are simply added in an overlay part 118.7 to generate the total wind control information TWCI which generates a total action at the actuators 107.1, 117.1.
  • the overlay, at the actuators 107.1, 117.1 hence generates a simple sum of the individual actions corresponding to the base wind control information BWCI and the gust wind control information GWCI.
  • the side wind compensation device 118 has a first gust control activation part 118.8 that activates the gust side wind control mode GWCM only if the base wind control information BWCI exceeds a predeterminable threshold value representative of a predeterminable level of action of the active device, i.e. representative of a certain noticeable amount of base side wind load BSWL. Otherwise the gust side wind control mode GWCM is deactivated by setting both limits of the limiter control part 118.6 to zero.
  • the side wind compensation device 118 has a second gust control activation part 118.9 activating the gust wind control mode GWCM only if the base action at the actuators 107.1, 117.1 according to the base wind control information BWCI and the gust action at the actuators 107.1, 117.1 according to the gust wind control information GWCI have the same sense of action. This is done by setting one limit of the limiter control part 118.6 to zero and by setting the sign of the non-zero limit of the limiter control part 118.6 as a function of the base wind control information BWCI.
  • the side wind compensation device 118 has a third gust control activation part 118.10 activating the gust side wind control mode GWCM only if the first rolling rate RRB1 lies within a tolerance band TB defined as a function of the first rolling rate RRB1 and the second rolling rate RRB2. This avoids overreactions and increases overall stability of the side wind control mode SWCM.
  • a fourth gust control activation part 118.10 of the side wind compensation device 118 detecting travel of the vehicle 101 on a twisted track section and activating the gust side wind control mode GWCM only if travel outside a twisted track section is detected. This is done as a function of the a yaw acceleration signal AWBYAW of the wagon body, a signal representative of twisted track section entry TTENTRY and a signal representative of twisted track section exit TTEXIT (all captured or determined by suitable means).
  • System damping is achieved in the present example by the controller 117.2 setting the control components controlling the dynamic part of the rolling compensation arrangement in the track feedback control mode TFCM to a maximum damping mode MDM if the gust side wind control mode GWCM is activated.
  • the rolling compensation arrangement in the maximum damping mode MDM, provides maximum damping of the yaw motion of the wagon body 102 about its yaw axis. This avoids that (generally possible) conflicting actions of the side wind control mode SWCM and the track feedback control mode TFCM lead to control system instabilities.
  • the side wind compensation device 118 may generally be constantly active. In the present example, however, the side wind compensation device 118 is only active under side wind critical operating conditions, in order to largely avoid interference with other control functions, such as quasi-static track curvature dependent tilt control and dynamic comfort control of the track feedback control mode TFCM. In the present example, the side wind compensation device 118 is only activated in the controller 107.2 if a running speed V of the vehicle exceeds a side wind control activation threshold of 160 km/h.
  • control device 107.2 is designed in order to control the first actuator 107.1 and the second actuator 117.1 in the side wind control mode SWCM in such a way that both the first transverse deflection and also the second transverse deflection of the wagon body 102 are reduced by identical concurrent actions as a function of the total wind control information TWCI, so that, overall, a reduction in the deviation dy results.
  • the track feedback control mode TFCM and the side wind control mode SWCM are typically active at the same time.
  • the control device 107.2 controls the actuators 107.1 and 117.1 using an overlay of the total wind control information TWCI coming from the side wind control mode SWCM and a total track feedback control information TTFCI issued by the track feedback control part of the control device 107.2 executing the track feedback control mode TFCM.
  • control device controls the first actuator 107.1 and the second actuator 117.1 such that the deviation dy between the first transverse deflection and the second transverse deflection is less than 10 mm.
  • control device 107.2 may comprise a further detection devices detecting a variable representative of the first transverse deflection of the wagon body 102 and a variable representative of the second transverse deflection of the wagon body 102, which are then used for reference purposes to verify proper control of the first actuator 107.1 and of the second actuator 117.1.
  • the further detection device here can be realized by a deflection sensor or similar integrated in the respective actuator 107.1, 117.1.
  • an additional passive measure may be taken to reduce the effects of side wind loads SWL, in particular side wind induced wheel unloading.
  • rigidities of the primary spring devices 103.1 of the first bogie 104 and the second bogie 114 in the height direction (z f -axis) may have different values. More precisely, the first primary spring rigidity PSR1 of the first bogie 104 may be selected to be different from, in particular lower than, the second primary spring rigidity PSR2 of the second bogie 114.
  • the second primary spring rigidity PSR2 is increased with respect to the embodiments described above.
  • the first primary spring rigidity PSR1 may be reduced with respect to the embodiments described above.
