DETAILED DESCRIPTION

Disclosed embodiments relate to an operating device for a transportation vehicle.

An operating device of such a type has become known from DE 10 2014 016 570 A1. Specifically, this document discloses a transportation vehicle door with an arm support, on the upper side of which an operating device, such as a touchscreen, has been integrated. The touchscreen exhibits an operating panel which is capable of being switched over between several display modes. In the first display mode, operating symbols for selecting operable actuators (exterior mirrors, window regulators, seats and doors) are displayed; after selection of one of the operable actuators, a switch-over to a second display mode is implemented. In the second display mode, the touchscreen displays, in each instance, an operating symbol specific to the respectively selected, operable actuator.

In DE 103 24 918 A1 an operating device is disclosed for adjusting adjustable components of a transportation vehicle, the operating device exhibiting an operating area that is a pressure-sensitive area sensor. Furthermore, membrane pushbutton switches are present. By sliding motion of a finger over the operating area, an adjustment of a component can be implemented that correlates with the linear path of the implemented touching.

Finally, an operating device for actuating window regulators is described in DE 10 2005 051 786 A1. In this case, two opening/closing switches are present for opening and closing, in each instance, two windows at the front or at the back. In the vicinity of the opening/closing switches a selector switch is arranged for switching over between the actuation of the front or the rear windows.

In view of this state of the art, the disclosed embodiments make available an operating device for a transportation vehicle that enables a convenient operation of the windows of the transportation vehicle and that is of compact design.

This is achieved by an operating device for a transportation vehicle.

The disclosure takes as its starting-point an operating device for a transportation vehicle, having at least one touch-sensitive operating region. The touch-sensitive operating region serves for displaying at least one operating symbol and for actuating at least one window regulator.

The touch-sensitive operating region may be a touchscreen, though a different design of the operating region, for instance, a touchpad, is entirely conceivable.

The disclosure now proposes that the operating device, viewed in an imaginary mounted state in the transportation vehicle, exhibits an upper side and a front side adjacent thereto. The upper side accordingly faces toward a headliner of the transportation vehicle, and the front side faces toward an instrument panel or a windshield.

At least one touch-sensitive operating region for actuating a window regulator is arranged both at least on one part of the upper side and at least on one part of the front side.

By virtue of these features, the basic prerequisites are created so that the operating device can be kept very compact and hence space-saving in the x-direction—that is to say, in the longitudinal direction of a transportation vehicle. For by virtue of the arrangement of touch-sensitive operating regions for actuating windows on the front side and on the upper side, conventional finger depressions in the region of the opening/closing switches for the windows, or additional operating areas, can be avoided.

A further disclosed embodiment proposes that all the sides of the operating device extending downward from the upper side include an angle of at most 90 degrees with the upper side. These features constitute the basic prerequisite so that the operating device can be produced without undercuts and therefore with low tooling costs. Otherwise necessary slides and such like in a tool can be dispensed with. The supporting structure (body) of the operating device may be produced in a plastics injection-molding method. The body of the operating device is accordingly formed in one piece, reducing the manufacturing effort.

To enable an agreeable operation of the operating device, it is further proposed that the at least one touch-sensitive operating region located on the upper side for actuating the window regulators includes an angle that is less than 90 degrees with the at least one operating region located on the front side for actuating the window regulators. This angle may lie within a range from about 60 degrees to 80 degrees.

A further disclosed embodiment proposes that touch-sensitive operating regions are present which serve either for actuating the front window regulators or for actuating the rear window regulators, in which case a touch-sensitive operating region is likewise present for switching over between an actuation of the front window regulators or of the rear window regulators. In this way, it is made possible to make do with a minimum of operating regions. Accordingly, separate operating regions do not have to be provided for operating the front and the rear window regulators. This leads likewise to a reduction of the space requirement of the operating device.

In the following, further developments of the operating device will be presented which in each instance lead to a simplification of operation or in each instance to a more intuitive understanding in operation.

Accordingly, the following further disclose embodiments are conceivable:By a wiping motion and/or by a double tapping, which in each instance is executed on the at least one touch-sensitive operating region for actuating at least one window regulator, at least one window is capable of being opened or closed in a continuous action. In this connection, the continuous action can be terminated by a single tapping on the at least one touch-sensitive operating region for actuating at least one window regulator.By a sustained touching contact on the at least one touch-sensitive operating region for actuating at least one window regulator, at least one window is capable of being opened or closed in a manual action. In this connection, the manual action of the at least one window can be terminated by a lifting of a touching element away from the at least one touch-sensitive operating region for actuating at least one window regulator.By a double tapping on the touch-sensitive operating region for switching actuation over between the front window regulators and the rear window regulators, and by a subsequent touching of at least one touch-sensitive operating region for actuating the window regulators, all the windows are capable of being opened or closed simultaneously. By virtue of this operation, a very comfortable ventilation function is accordingly achievable.At least one touch-sensitive operating region is present for locking or unlocking all the doors of the transportation vehicle. In this connection, the locking is capable of being implemented by a single tapping on the touch-sensitive operating region for locking or unlocking all the doors of the transportation vehicle, or even by simultaneous touching of several touch-sensitive operating regions of the operating device. An unlocking can be implemented by single tapping on the touch-sensitive operating region for locking or unlocking all the doors of the transportation vehicle.

In a further disclosed embodiment, the following features are also proposed for the purpose of facilitating operability:By a wiping motion contrary to a direction of travel and/or by a double tapping, which in each instance is executed on the at least one touch-sensitive operating region located on the upper side for actuating the window regulators, at least one window is capable of being opened in a continuous action. In this connection, the continuous action is capable of being terminated by a touching of at least one touch-sensitive operating region located on the upper side for actuating the window regulators.By a sustained touching contact on the at least one touch-sensitive operating region located on the upper side for actuating the window regulators, at least one window is capable of being opened in a manual action. The manual action of the at least one window can be terminated by a lifting of a touching element away from the at least one touch-sensitive region located on the upper side for actuating the window regulators.By a wiping motion upward in the direction of the upper side and/or by a double tapping, which in each instance is executed on the at least one touch-sensitive operating region located on the front side for actuating the window regulators, at least one open window can be closed in a continuous action.By a touching of the at least one touch-sensitive operating region located on the front side for actuating the window regulators, the continuous action can be terminated.By a sustained touching on the at least one touch-sensitive operating region located on the front side for actuating the window regulators, at least one window is capable of being closed in a manual action. By a lifting of a touching element away from the at least one touch-sensitive region located on the front side for actuating the window regulators, the manual action of the at least one window can be terminated.It is also conceivable that, by virtue of a touching of the at least one touch-sensitive operating region located on the front side for actuating the window regulators, followed by a touching of the at least one touch-sensitive operating region located on the upper side for actuating the window regulators, at least one window is capable of being closed in a continuous action.

With the disclosed embodiments, a transportation vehicle that is equipped with at least one disclosed operating device is to be accorded protection.

Reference will firstly be made toFIG.1, in which the passenger compartment of a transportation vehicle K in the region of its cockpit is evident. The transportation vehicle K exhibits on its door an arm support2, into which an operating device1has been integrated.

In the represented mounted position of the operating device1, merely an upper side10of its body is evident The upper side10is oriented approximately flush with an upper side2aof the arm support2. At least, upper side10does not protrude appreciably from upper side2a. Moreover, a front side11is freely accessible and capable of being touched by fingers of an operator. A touching of the front side11can be effected in extremely simple manner by an operator positioning his/her left hand above or on the upper side10. In this connection, his/her downwardly directed fingers have simultaneously been automatically positioned over the front side11. A touching of the front side11and hence an operation of operating elements that are present there is accordingly very readily possible.

In the mounted state represented, the upper side10is directed toward a roof liner, not represented in any detail, of the transportation vehicle K, and the front side11is directed toward an instrument panel3or a windshield located behind it.

In the following, reference will be made toFIGS.2to4, which show the body of the operating device1in isolation. The body of the operating device1is made of plastic and has been produced in one piece—that is to say, from one piece—in a plastics injection-molding method.

As is evident, the operating device exhibits an upper side10, a front side11, a left side12and a right side13, in an imaginary direction of travel F. A back side is numbered14.

Furthermore, several touch-sensitive operating regions25,26,27and28are arranged on the upper side10.

Within operating region25, operating symbols15and16are present for actuating a window regulator on the left side, in the direction of travel, of the transportation vehicle K, and operating symbols17and18are present for actuating a window regulator on the corresponding right side of the transportation vehicle K. Furthermore, an operating symbol19is present with which a switch-over is possible between an actuation of the front window regulators and an operation of the rear window regulators at the rear of the transportation vehicle K, and conversely.

Equally, on the front side11, within a touch-sensitive operating region29, operating symbols15aand17aare present which likewise serve for actuating the window regulators.

It is also conceivable that the individual touch-sensitive operating regions25to29, or one contiguous touch-sensitive operating region, is/is not a touchscreen but has/have been designed as a touchpad. In this case, the operating symbols may be, in straightforward manner, symbols capable of being illuminated from behind, which are backlit, or not, depending upon the operating mode or display mode.

Operating symbols20and21serve for initiating the adjustment of an adjustable exterior mirror on the left side or on the right side.

Via an operating symbol22, a heater of the exterior mirrors can be activated. Furthermore, via an operating symbol23a child safety lock (deactivation of a possible actuation of windows and doors at the rear of the transportation vehicle) is capable of being activated, and with an operating symbol24a simultaneous locking of all the doors is possible.

Since the stated operating symbols are all located respectively on touch-sensitive operating regions, a touching of the operating symbols, as will be described in more detail in the following, is sufficient for operating the correspondingly assigned functions.

In a departure from the exemplary embodiment, it is conceivable that several touch-sensitive operating regions have been combined to form a larger touch-sensitive operating region. It is also conceivable to replace the touch-sensitive operating regions25to29with a single touch-sensitive operating region. On the other hand, it is also conceivable that a touch-sensitive operating region has been assigned to each operating symbol.

Attention is also to be drawn expressly to the fact that the operating device1or its body has been designed in such a manner that all the sides11,12,13and14extending downward from the upper side10include with the upper side10an angle that amounts to at most 90 degrees and is optionally less than 90 degrees. In other words, the body of the operating device1has been designed in such a way that it is capable of being produced in one piece by a plastics injection-molding method and capable of being readily demolded from the tool in a mold-release direction E.

By way of example, angles β have been drawn in that sides12and13respectively include with the upper side10.

An angle that the imaginary extensions of touch-sensitive operating regions25and29form with one another has been identified by α. By such a configuration of the angle α, very good haptics and operability of the operating device1can be achieved.

The operation of the operating device1can now be implemented in the following way:

Operation of the Window Regulators:By a wiping motion contrary to an imaginary direction of travel F, and/or by a double tapping, which in each instance is executed on the at least one touch-sensitive operating region25located on the upper side10for actuating the window regulators, at least one window can be opened in a continuous action. Accordingly, if an operator performs such a wiping motion in the region of operating symbols15and/or16, in the display mode represented the window of the driver's left door is opened in a continuous action. By a touching of operating region25in the region of symbols15and/or16, the continuous action can be terminated at any time.By a sustained touching contact (that is to say, tapping and holding) on the at least one touch-sensitive operating region25located on the upper side10, it is possible to open at least one window in a manual action. By a lifting of the touching element away from the at least one touch-sensitive operating region25located on the upper side10, the manual action of the at least one window is terminated. Accordingly, if an operator taps on operating region25in the region of operating symbols15and/or16and keeps his/her finger on operating region25, a manual opening action of the window of the driver's door starts. If the operator lets go of operating region25, the manual action is stopped.

The operation of the window of the passenger door is undertaken analogously via operating symbols17and18.If a closing of an open window is desired by the operator, by a wiping touching of touch-sensitive operating region29in the region of operating symbols15aupward—that is to say, in the direction of the arrows represented by operating symbols15aor17a—he/she can close an open window in a continuous action. Accordingly, if an operator performs an upwardly directed wiping motion on operating symbol15a, an open window of a driver's door is closed again in a continuous action.If a manual closing movement of an open window is to be implemented, operating region29has to be touched in a sustained touching in the region of operating symbols15aor17a. Accordingly, if an operator touches, for instance, operating symbol15aand leaves his/her finger in contact with operating region29, the open window on the driver's side commences a closing motion and runs until such time as the window has been closed completely or until the operator previously lifts his/her finger away again from operating symbol15a.

It will be understood that the operation of the window regulators both on the driver's side and on the passenger side takes place in the same way.If an operation of the rear windows at the rear of the transportation vehicle K is desired by the operator, a touching of operating symbol19is sufficient. In this case, a brighter or differently-colored illumination of operating symbol19(so-called toggle function) takes place, to draw attention to the activated operability of the rear windows. The operation of the rear windows is then possible in a manner analogous to the operation of the front windows.

The subsequent switch-over to operability of the front windows again can be undertaken by renewed tapping on operating symbol19, whereupon the backlighting of operating symbol19is deactivated again. But it is also conceivable to have the switching over to front operation implemented via a timing system. That is to say, after expiration of a defined or definable time the operability changes automatically from rear operation to front operation again.

By virtue of the front side11, exposed in the mounted position, with touch-sensitive operating region29which merges with touch-sensitive operating region25of the upper side10, the operating device1is capable of being realized so as to be very space-saving in the X-direction (longitudinal direction of the transportation vehicle K). Besides, by virtue of the represented configuration, a “pull to close” operation, required for safety reasons, is possible in very space-saving manner.

Finally, in connection with the operation of the window regulators an unusually beneficial ventilation function is also to be pointed out:

If an operator touches operating symbol19by a double tapping (that is to say, brief tapping twice), operating symbol19starts to flash for a short time, optionally for approximately 5 seconds. If during this time the operator touches one of operating symbols15,16,17and/or18, all the windows are opened simultaneously.

If the operator desires a simultaneous closing of all the open windows, he/she can bring this about analogously by touching operating symbol19likewise by a double tapping and by subsequently touching one of operating symbols15aand/or17aby tapping on it within a defined waiting-period.

Incidentally, the start of a continuous action for opening a window by a double tapping of operating symbols15and/or16, or17and/or18, is also conceivable. A closing of a window in a continuous action is equally conceivable by double tapping of operating symbols17aand/or15a.

The selection of an exterior mirror to be adjusted is undertaken by touching either operating symbol20(left exterior mirror) or operating symbol21(right exterior mirror).

If an operator touches operating symbol21, for instance, the representation or visibility of the operating symbols changes to another display mode or operating mode.

This is represented inFIG.5. It is evident therein that operating symbols15to19have disappeared or are no longer visible, and other arrow-like operating symbols30,31,32and33are apparent. Specifically, by touching operating symbols32and33an adjustment of the right exterior mirror about a vertical swivel axis can be brought about, and by touching operating symbols30and31an adjustment of the right exterior mirror about a horizontal swivel axis can be brought about. The adjustment of the left exterior mirror takes place analogously after touching operating symbol20(compareFIG.3).

FIG.6shows an operating mode in which the adjustment of the left exterior mirror was selected via operating symbol20(cf.FIG.3). In contrast toFIG.5, in this case operating symbols23and24are also no longer apparent as a possible option.

It is also worth mentioning that the transportation vehicle K can be completely locked not only by a tapping on operating symbol24but also by simultaneous tapping on two or more of the aforementioned operating symbols. By this, it is made possible for an operator to be able to lock the transportation vehicle K without any problems even in a panic situation.
