Description

The invention relates to an operating device with a control lever for controlling a vehicle, in particular for controlling a locomotive or a traction vehicle.

The EP 0 687 609 A1 describes a control lever, with both the brakes and the drive can be controlled simultaneously depending on its angular position.

Other operating levers are in the EP 1 400 426 A2 and in the WO 2008/009443 A1 described.

In rail vehicles, such as locomotives or locomotives, usually operating levers are used, in which by adjusting the deflection angle of the operating lever, the operating function to be performed is selected operator side. Deflection angle, which is associated with a specific operating function, are fixed in previously known control levers, for example by a locking disk.

The invention has for its object to provide an operating device of the type mentioned, which is user-friendly than previous controls.

This object is achieved by an operating device with the features of claim 1. Advantageous embodiments of the operating device according to the invention are specified in subclaims.

Thereafter, the invention provides that the operating device has a control device which is a force-related operating mode, in which the operator is set a force on the operator side, which is to be applied to the vehicle, and a speed-related mode, set in the operator with the operating lever speed is to reach the vehicle allows, with the control device, a selection device connected to the operating mode or the speed-related operating mode of the operating device operator selectable, and the controller generates a control signal depending on the selected mode and the respective position of the operating lever on the output side indicating the respective operating command of the operating lever.

A significant advantage of the operating device according to the invention is the fact that it has a switchover, so that it is an operator, so usually the driver, is possible to control the vehicle either power related or speed related. Such a changeover allows a change in the operating philosophy, without requiring a replacement of the operating lever or other parts would be required.

Another significant advantage of the operating device according to the invention is that a switchover is also possible while driving the vehicle and the driver thus depending on the driving situation has the ability to dynamically select that mode or that operating philosophy that best fits the particular driving situation ,

In order to avoid that there is an undesirable change in the driving behavior, in particular the drive or braking behavior of the vehicle, it is considered advantageous if the control device is designed such that it, after a user-side change of mode, the operating device for a given Time period inactive switches. Such inactive switching gives the driver the opportunity to check if the position of the operating lever is correct or desired, so that it can correct the position of the operating lever within the specified period of time in the event of a deviation; This makes it possible, for example, to prevent the vehicle from accelerating after switching the operating mode, although braking of the vehicle is necessary and previously set.

Preferably, in the predetermined time period of the inactive switching, the control device outputs a control signal which corresponds to the control signal at the time of the changeover of the operating mode; this ensures continuity in the handling of the vehicle. In other words, the control device is preferably configured such that it leaves the control signal unchanged after a user-side changeover of the operating mode for a predefined period of time.

The operating device preferably has a display device which displays the respectively selected operating mode. Thus, the driver is always signaled which mode is currently active, and it is a misoperation avoided.

Preferably, the display device alternatively or additionally also displays the respectively selected operating command of the operating device. Such an indication of the present operating command makes the vehicle control particularly comfortable.

The respective operating position can be determined particularly simply and thus advantageously when an angle measuring device for detecting the adjustment angle of the operating lever is in communication with the control device and the control device is adapted to generate the control signal with the detected angle value of the angle measuring device and the operating mode selected operating mode.

Preferably, an individual Verstellwinkelbereich is assigned to the operating lever for each operating command, and the control device checks, for example, which operating mode is selected and in which Verstellwinkelbereich the detected angle value falls, and generates in dependence on the determined Verstellwinkelbereich and the determined mode, the control signal.

In order to simplify a double use of the operating lever for the two different operating philosophies, it is considered advantageous if the operating lever has no detent position and is self-holding within the entire adjustment range of the operating lever.

Alternatively, it can be provided that the operating lever provides a single detent position, namely a detenting zero position, and, moreover, operates detent-free and is self-holding within the entire remaining adjustment range of the operating lever. The latching zero position is preferably located in an axis of symmetry of the adjustment angle range or the operating device.

The force-related operating mode and the speed-related operating mode can, for example, be position-dependent and / or time-dependent. A position-dependent operating mode is understood to mean that the operating command is determined by the respective position of the operating lever. A time-dependent mode of operation is understood to mean that the operating command depends, among other things, on how long the Control lever remains in a predetermined position: In the time-dependent mode, for example, be provided that the driving force of the drive is continuously increased, as long as the operating lever is in the position "increase the driving force", and is continuously reduced, as long as the operating lever in the Position "reduction of driving force" is located. Similarly, the braking force or the vehicle speed can be increased or reduced by adjusting corresponding positions of the operating lever for increasing or decreasing the braking force or the vehicle speed.

The invention also relates to a method for generating a control signal indicating an operating command of an operating lever, in particular for controlling a locomotive or a traction vehicle, wherein it is checked whether a speed-related operating mode or a force-related operating mode has been selected by the operator, and in dependence the selected operating mode and the respective position of the operating lever on the output side, a control signal is generated which indicates the respective operating command of the operating lever.

In order to ensure the greatest possible ease of use when controlling the vehicle, the invention provides that after a user-side switching the operating mode, the operating device is switched inactive for a predetermined period of time and in the predetermined period of inactivating a control signal is output to the control signal at the time Changing the operating mode corresponds.

With regard to the advantages of the method according to the invention, reference is made to the advantages of the operating device according to the invention, since the advantages of the method according to the invention essentially correspond to those of the operating device according to the invention.

It is considered advantageous if, after a user-side changeover of the operating mode, the operating device is switched inactive for a predetermined period of time and a control signal is output in the predetermined period of inactivation which corresponds to the control signal at the time of the changeover of the operating mode.

Preferably, the adjustment angle of the operating lever is measured, and the control signal is generated with the measured angle value, taking into account the operating mode selected operating mode.

According to a particularly preferred embodiment of the method is provided that the control lever for each operating command each an individual Verstellwinkelbereich is specified and is checked which mode is selected and in which Verstellwinkelbereich the detected angle value falls, and the control signal in dependence on the determined Verstellwinkelbereich and the determined operating mode is generated.

For the sake of clarity, the same reference numbers are always used in the figures for identical or comparable components.

In the FIG. 1 One sees a first embodiment of an operating device 10, which is equipped with an operating lever 20. The operating lever 20 is held pivotably within a swivel angle range or adjustment range γ and can assume an arbitrary displacement angle α within the adjustment range γ.

As reflected in the FIG. 1 can be seen, the adjustment range γ is configured symmetrically and has a central axis or axis of symmetry 30, which divides the adjustment into two large partial angle sections. In the area of the axis of symmetry 30 or center axis of the operating lever 20 is held detent, so that the center axis forms a latching zero position for the operating lever 20. Outside the range of the center axis or outside of the axis of symmetry 30, the adjustment range is rest-free, wherein the operating lever is self-holding in any position outside the symmetry axis 30. Such a latching can be achieved for example by a corresponding friction of the operating lever 20.

For detecting the respective adjustment angle α of the operating lever 20, the operating device 10 has an angle measuring device 40 which measures the displacement angle α, generates a corresponding displacement angle value D (α) and emits this on the output side. Downstream of the angle device 40 is a control device 50 of the operating device 10.

Also connected to the control device 50 is a selection device 60 of the operating device 10. With the selection device 60 can be selected on the operator side or vehicle driver side, with which operating mode, the operating device 10 is to be operated. A speed-related position-dependent operating mode BA is available, in the Figures 2 and 4 is characterized by a logical one (BA = 1), as well as a force-related position-dependent mode, which in the Figures 3 and 4 is characterized by a logical zero (BA = 0).

A speed-related position-dependent operating mode BA = 1 is understood to mean that the speed of the vehicle depends on the respective position of the operating lever and is independent of how long the operating lever has already remained in the respective position. An exemplary embodiment for a speed-related position-dependent mode of operation is described below in connection with FIG FIG. 2 explained.

A force-related position-dependent operating mode BA = 0 is understood to mean that the force acting on the vehicle, for example the drive or braking force, is determined by the respective position of the operating lever and is independent of how long the operating lever has already remained in the respective position , An embodiment of a force-related position-dependent mode of operation is described below in connection with the FIG. 3 explained.

With the selection device 60, therefore, it can be determined on the operator side whether the operating device is to be operated speed-related or force-related. In the embodiment according to the FIG. 1 the selector 60 is a separate component connected to the controller 50. Alternatively, the selection device 60 can also be arranged in or on the operating lever 20, in particular in or on the knob 70 of the operating lever 20.

How is the FIG. 1 In addition, the operating device 10 has a display device 80, which is connected to the control device 50.

The operating device 10 can be operated, for example, as follows:

With the signals present on the input side, that is to say the adjustment angle value D (α) of the angle measuring device 40 and the selection signal AS of the selection device 60, the control device 50 determines a control signal ST and outputs it on the output side. With the control signal ST, the respective operating command BF of the operating lever 20 is displayed or output. Since the operating command BF depends on the respective operating mode, the control signal ST is therefore always also a function of the value of BA; this is in the FIG. 1 indicated accordingly.

In addition, the control device 50 generates on the output side a display signal AZ, which arrives at the display device 80 and determines which display is to be displayed on the display device 80. Preferably, the display signal AZ causes a display of the respectively current operating command BF and the current operating mode BA.

The FIG. 2 shows by way of example how a division of the adjustment range γ in accordance with FIG. 1 in a Verstellwinkelbereich Δγ0 (α ≥ 0) and a Verstellwinkelbereich Δγ1 (α <0) can be done to allow a speed-related position-dependent mode (BA = 1) of the operating device 10. In the Verstellwinkelbereiche Δγ0 each angular value α is assigned a speed value v (α), so that by pivoting the operating lever 20, the speed can be adjusted. The Verstellwinkelbereich Δγ1 (α <0) is preferably in this mode of operation and leads to a vehicle speed V = 0.

In the FIG. 3 shows by way of example how the adjustment range γ in the case of a force-related position-dependent mode (BA = 0) can be used. In the case of a position-dependent mode of operation, the resulting force-related operating command depends on which adjustment angle α of the operating lever 20 respectively.

If the operating lever 20 is in the adjustment angle range Δγ7, then the drive of the vehicle should exert a positive driving force. The respective driving force value is determined by the respective displacement angle α within the adjustment angle range Δγ7. For example, the greater the displacement angle α of the operating lever, the greater the driving force is set.

In a corresponding manner, the braking force is adjusted by pivoting the operating lever 20 in the Verstellwinkelbereich Δγ8, for example, a large displacement α - with respect to the axis of symmetry 30 - a large braking force and a small adjustment angle α has a small braking force.

In Verstellwinkelbereich Δγ0 neither a driving force nor a braking force is generated, so that the vehicle unrestrained and unaccelerated his state of motion - apart from friction, air resistance and other influences - retains.

The operation of the operating device 10 according to FIG. 1 should now in conjunction with the FIG. 4 be explained in more detail: In the FIG. 4 It can be seen how an actuation of the selector 60 and generating a selection signal AS causes a change in the mode BA. However, if the selector 60 is activated and a selection signal with a logical "1" is generated, this does not directly result in a change in the mode; only when the selection signal AS is generated at least during a predetermined minimum period Tmin with a logical "one", a switching of the mode BA is caused.

In the FIG. 4 is an example of switching the mode at time t = t1 shown. At the time t1, the selection signal AS has a logic "1" for the predetermined time Tmin, so that the mode is switched from BA = 0 to BA = 1. This means that from a position-dependent force-related mode of operation (BA = 0), as used in connection with the FIG. 3 is changed into a position-dependent speed-related mode (BA = 1), as in connection with the FIG. 2 has been explained.

In the FIG. 4 In addition, the respective status Z of the operating device 10 is shown. If the status Z has a logical "1", then the operating device 10 is active and the control device 50 generates the control signal ST on the output side, which corresponds to the respective operating position or the respective displacement angle α of the operating lever 20 and the respective operating mode BA. On the other hand, if the status Z has a logical "0", then the operating device 10 is inactive and, on the output side, generates a control signal ST which indicates the respectively selected operating command given to the operating device 10 at the time before the changeover of the operating mode. In other words, during the state Z = 0, ie during the time period Ts, the control signal ST will remain constant and correspond to the control signal ST generated at the time t1. Only after expiration of the time period Ts, the operating device 10 is again activated, so that the control signal ST again corresponds to the respective adjustment angle α of the operating lever 20 and the respectively selected mode BA. The reactivation of the operating device 10 after expiration of the inactive phase Ts is in the FIG. 2 symbolized by a return of the status Z from a logical "0" to a logical "1". At the time t1 + Ts, the operating device 10 is thus active and subsequently operates in the speed-related operating mode (BA = 1).

In the FIG. 4 In addition, switching from the speed-related operating mode BA = 1 to the force-related operating mode BA = 0 is shown. That's how it works FIG. 4 can be seen that at the time t = t2 due to a generation of the selection signal AS with a logical 1 for a period greater than or equal to Tmin a mode change is caused. Even with this switching of the operating mode from BA = 1 to BA = 0, the status Z of the operating device 10 is changed and the operating device 10 is switched inactive for a time Ts. This means that the control signal ST, which has been generated at the time t = t2, remains constant at the output of the control device 50 and is changed only after expiration of the time Ts, ie at the time t2 + Ts, of course only if this then the respective position of the control lever 20, so the Verstellwinkelwert D (α), taking into account the then activated force-related mode BA = 0 commands.

By inactivating the operating device 10, it is avoided that after a change of operating mode, that is to say switching from BA = 0 to BA = 1 or switching from BA = 1 to BA = 0, an undesired change in the vehicle condition can take place. Namely, during the predetermined inactive phase Ts, the vehicle driver or the operator of the operating device has the option of setting the respective position of the operating lever 20 with the knob 70 in accordance with the desired driving state of the vehicle in the newly set operating mode.

In the embodiment according to FIG. 4 a switching of the mode BA is caused when the actuation of the selector 60 and generating the selection signal AS with a logical 1 at least during the predetermined minimum time Tmin. Alternatively, switching of the operating mode BA can also take place under other conditions, for example when a selection signal AS with a predetermined binary or analog coding sequence is generated, for example in the form "short-long-long" or "short-short-long" or like.

In the FIG. 5 one sees a second embodiment of an operating device; this is designated by the reference numeral 10 '. The operating device 10 'also has an operating lever 20, which is held pivotably within a swivel angle range or adjustment range γ and can assume an arbitrary displacement angle α within the adjustment range γ.

In contrast to the operating device 10 according to FIG. 1 are in the operating device 10 'according to FIG. 5 a speed-related position-dependent operating mode BA '= 1 and a force-related time-dependent mode BA '= 2 available (see. Fig. 7 ).

The speed-related position-dependent operating mode BA '= 1 corresponds to the operating mode BA = 1, as used in connection with the FIG. 2 has been explained, so that reference is made in this regard to the above explanations.

• Δγ0: Antriebskraft und Bremskraft = 0
• Δγ1: Antriebskraft wird kontinuierlich reduziert
• Δγ2: Antriebskraft bleibt konstant
• Δγ3: Antriebskraft wird kontinuierlich erhöht
• Δγ4: Bremskraft wird kontinuierlich reduziert
• Δγ5: Bremskraft bleibt konstant
• Δγ6: Bremskraft wird kontinuierlich erhöht.

The FIG. 6 shows by way of example how the division of the adjustment range γ in accordance with FIG. 1 can be done in Verstellwinkelbereiche Δγ0 to Δγ6 to allow the force-related time-dependent mode BA '= 2 of the operating device 10. For example, the following operating commands are assigned to the individual adjustment angle ranges Δγ0 to Δγ6:

• Δγ0: Driving force and braking force = 0
• Δγ1: Driving force is continuously reduced
• Δγ2: Driving force remains constant
• Δγ3: Driving force is continuously increased
• Δγ4: braking force is reduced continuously
• Δγ5: braking force remains constant
• Δγ6: Braking force is increased continuously.

In the force-related time-dependent operating mode BA '= 2, the set driving force or the set braking force thus depends on how long the operating lever 20 is in the driving force changing or braking force changing adjustment range Δγ1, Δγ3, Δγ4 and Δγ6. In the Verstellwinkelbereiche Δγ2 and Δγ5 the driving force or the braking force remains unchanged or constant at their respective value.

Also in the second embodiment according to the FIG. 5 the activation of a new operating mode after switching the operating mode BA 'preferably takes place only after an inactive phase Ts (cf. FIG. 7 ). Also can be in the FIG. 7 recognize that it is preferable to switch the operating mode BA 'only when the selection device 60 is actuated and the selection signal AS is generated with a logic 1 for at least a predetermined minimum time period Tmin. Alternatively, the switching of the operating mode BA 'can also take place under other conditions, for example if a selection signal AS is generated with a predetermined binary or analog coding sequence, for example in the form of "short-long-long" or "short-short-long" or similar.

In the FIG. 8 The operating device 10 "is equipped with an operating lever 20, which is held pivotably within a swivel angle range or adjustment range γ and can assume an arbitrary displacement angle α within the adjustment range γ.

In contrast to the operating devices 10 and 10 'according to the FIGS. 1 and 5 are in the operating device 10 "according to FIG. 8 three modes BA "available, namely a speed-related position-dependent mode BA" = 1, a force-related position-dependent mode BA "= 0 and a force-related time-dependent mode BA" = 2.

The speed-related position-dependent operating mode BA "= 1 can correspond, for example, to the operating mode BA = 1, as described in connection with FIG FIG. 2 has been explained. The force-related position-dependent operating mode BA "= 0 can correspond, for example, to the operating mode BA = 0, as described in connection with FIG FIG. 3 has been explained.

The force-related time-dependent operating mode BA "= 2 may correspond, for example, to the operating mode BA '= 2, as described in connection with FIG FIG. 6 has been explained.

Also in the third embodiment according to the FIG. 8 the activation of a new operating mode after switching the operating mode preferably takes place only after an inactive phase Ts and preferably only when the selection device 60 is actuated and the selection signal AS is generated with a logical 1 for at least a predetermined minimum time Tmin (cf. Fig. 9 ). Alternatively, the mode of operation BA "can also be switched under other conditions, for example when a selection signal AS with a predetermined binary or analog coding sequence is generated, for example in the form" short-long-long "or" short-short-long " or similar.
