BACKGROUND INFORMATION
According to German Published Patent Application No. 101 39 693, in modern electronic devices in a vehicle which constantly offer additional functions with more and more options, multi-function operating elements, by which various functions of the connected devices can be controlled, have been created due to the limited installation space for the associated operating elements. Thus European Published Patent Application No. 0 366 132, for example, describes a multifunction operating device for motor vehicles, for which function groups and individual functions are selected with the aid of a rotary switch, and for which an ENTER function can be triggered, one and the same bidirectional rotary switch being used for selecting menus and individual functions. This rotary switch has click-stop positions, to which menus or individual functions are assigned, the ENTER function being able to be triggered by an axial motion of the rotary switch.
Furthermore, U.S. Patent Application Publication No. 2006/0146037, for instance, describes implementing similar, menu-driven operating concepts by touch screens in a motor vehicle. In this context, U.S. Patent Application Publication No. 2006/0146037 discloses an input device for a motor vehicle, which has a touch screen for the input of commands by touching a control panel or by exerting pressure on the control panel, an actuator for moving the touch screen in at least one direction with respect to a reference body, and a substantially U-shaped spring for the mechanical connection of the touch screen to the reference body.
German Published Patent Application No. 10 2006 029 506 discloses an input device for a motor vehicle, in which the input device includes a first display for the optical display of information, at least one second display, disposed above the first display, for the optical display of information, and a touch screen disposed above the second display, for inputting commands by touching a control panel of the touch screen, the second display being utilizable for the display of gesture recognition.
German Published Patent Application No. 103 42 666 discloses an operating system for a motor vehicle, which has an optical display unit for displaying at least one operating function, and at least one manual actuating device, which is assigned for operating the at least one displayed operating function of the optical display unit; at least one additional manual actuating device is provided and a sensor, which detects an approach towards the at least one additional actuating device, and an operating function assigned to the additional manual actuation device is able to be displayed on the optical display unit following the detected approach.
German Published Patent application No. 10 2005 035 111 discloses an operating and display system for a vehicle having a centrally disposed optical display unit, which simultaneously displays two different image outputs for different viewing angle ranges. A centrally placed operating element is provided and a detector unit, which detects an approach toward the central operating element as well as an operating action of the central operating element and assigns the detected operating action to a first viewing angle range or a second viewing angle range.
Additional operating concepts or man/machine interfaces are described in German Published Patent Application No. 197 53 742, German Published Patent Application No. 196 38 015, German Published Patent Application No. 10 2005 047 939, German Published Patent Application No. 10 2004 037 644, German Published Patent Application No. 10 2005 047 650, German Published Patent Application No. 10 2005 038 161, German Published Patent Application No. 10 2004 040 886, German Published Patent Application No. 10 2004 061 419, German Published Patent Application No. 103 24 579, German Published Patent Application No. 103 21 964, British Published Patent Application No. 2 418 741, U.S. Patent Application Publication No. 2006/0125803, U.S. Pat.

A function of a motor vehicle in the present context, in particular, includes a function for which a setpoint value is to be set from among a selection of values, in particular continuous values. A function of a motor vehicle in the present context, in particular, includes a function that is adjustable in analog fashion, especially according to a scale. In example embodiments of the present invention the function of the motor vehicle includes scrolling through a list. In example embodiments of the present invention the function of the motor vehicle includes shifting a map detail. In example embodiments of the present invention the function of the motor vehicle includes scaling a map detail. In example embodiments of the present invention the function of the motor vehicle includes moving an element represented on the display.
In example embodiments of the present invention the function of the motor vehicle is executed by the control. In example embodiments of the present invention, the control may be used to transmit a signal for executing the function of the motor vehicle.
In example embodiments of the present invention the motor vehicle includes an actuator for producing haptic feedback when the touch screen is touched. Details for haptic feedback are described in U.S. Patent Application Publication No. 2006/0146037, for instance. The haptic feedback of the operation confirmation may take place when touching the touch screen, for instance (in the region of an operating element shown with the aid of the display). As an alternative or in addition, three-dimensional structures, e.g., for sensing a displayed operating element in tactile manner, may be implemented by haptic feedback.
Example embodiments of the present invention provide a method for-operating a motor vehicle having a display for displaying variable information, and a touch screen, situated above the display, in particular, for inputting commands by touching the touch screen; using the display, an operating element is shown for operating or setting a function of the motor vehicle by touching the touch screen, especially in the region of the operating element, the function of the motor vehicle being executed or the execution of the function of the motor vehicle being initiated in response to a hand gesture executed in particular in the vicinity of the touch screen, without touching the touch screen.

If the touch screen is not situated above the display (and thus arranged as so-called touchpad), an operating element which is displayed by the display may also simply be information as to which function is able to be controlled just then using the touch screen.
In addition, an approach recognition may be provided as well, which is implemented with the aid of the gesture recognition module, for instance. If an approach recognition is provided, a change from a display mode to an operating mode may take place when a hand approaches a touch screen. In addition or as an alternative, it may be provided that a distinction is made, or may be made, between the operation by a driver and a passenger. As an alternative and in addition, the touch screen may also be arranged as a multi-touch function touch screen. For example, it may be provided that an operation is possible using multiple fingers simultaneously, the individual position of each finger being analyzed separately. Different functions of a touch-based gesture, for example, are able to be controlled as a function of the number of fingers used. Furthermore, it may be the case that route definitions and route estimates in a navigation system may be implemented by 2-finger ‘circle’ indications (see, for instance, www/jazzmutant.com/lemur_features.php and en.wikipedia.org/wiki/Multi-touch).

DETAILED DESCRIPTION
FIG. 1 shows the interior view of a motor vehicle 1, which is represented in a schematic diagram in FIG. 2. Motor vehicle 1 includes a display and operating device 4 integrated in instrument panel 3, next to steering wheel 2, which may be structured in the manner of the input device described in U.S. Patent Application Publication No. 2006/0146037, for instance. In addition, motor vehicle 1 includes a display control 10 for the coordinated control of display and operating device 4 having display and operating device 5. Display control 10 is connected via a bus system 20 to a Bluetooth interface 22, a navigation system 23, an automatic temperature control 24, an infotainment system 25, and a vehicle control device 26. Using display and operating device 4, for example, navigation system 23, automatic temperature control 24, infotainment system 25, vehicle control device 26 and—via Bluetooth interface 22—a mobile telephone are able to be operated.
Display and operating device 4 shown in exemplary form in FIG. 3 includes a display 12 for displaying variable information, and a touch screen 11, disposed above display 12, for inputting commands by touching touch screen 11. In this context it is provided, in particular, that an operating element for operating a function of motor vehicle 1 is displayed via display 12, by touching touch screen 11 in the region of the operating element. If touch screen 11 is touched in the region of the operating element, the corresponding function of motor vehicle 1 will be executed.
Furthermore, motor vehicle 1 includes a gesture recognition module 5 for recognizing a gesture executed in the vicinity of touch screen 11 in order to implement the function of motor vehicle 1. Gesture recognition module 5 may be limited to a pure sensor array, in which the analysis of a hand gesture may be implemented in display control 10. As an alternative, however, it may also be the case that the analysis of gestures takes place in gesture recognition module 5, and that already analyzed commands are transmitted to display control 10. Both arrangements of gesture recognition module 5 constitute exemplary embodiments for a gesture recognition module.
One function of motor vehicle 1 that is controllable by touch screen 11 and gesture recognition module 5, for example, may be the selection of an album or a CD in a CD changer, or the selection of a title from an album or a CD, as shown in FIG. 4 and FIG. 5 for example. FIG. 4 shows a list of available albums or CDs, the individual entries of the list being denoted by reference numerals 41, 42, 43, 44, 45, and 46. It may be provided that an album is selected by touching touch screen 11 in the region of the corresponding list entry 41, 42, 43, 44, 45, and 46.
Moreover, an operating element 30 is shown; touching of touch screen 11 in the region of operating element 30 results in a return to a superposed menu. Reference numerals 31 and 32 denote scroll buttons shown by display 12. For example, if touch screen 11 is touched in the region of scroll button 32, then the highlighting of individual list entries moves in a downward direction. In the example shown in FIG. 4, the highlight is assigned to list entry 46.
Instead of touching touch screen 11, gesture recognition module 5, for example, makes it possible for a downward gesture to likewise result in downward shifting of a highlighted list entry 41, 42, 43, 44, 45, 46. Thus, a corresponding gesture corresponds to touching of touch screen 11 in the region of scroll element 32. If a gesture toward the left takes place, then this too results in a return to a superposed menu. Thus, such a gesture corresponds to touching of touch screen 11 in the region of operating element 30. If an upwardly directed gesture occurs, then this corresponds to touching of touch screen 11 in the region of scroll button 31.
If a list entry 41, 42, 43, 44, 45, 46 is highlighted for a specific period of time, then it will be selected. In the present exemplary embodiment, the album ‘Good for your Soul’ is selected and thus the display of the titles of this album, as shown in FIG. 5 for example. List entries 51, 52, 53, 54, 55, 56 are shown as the titles. The selection of a title, for example, may be made in the same manner as described with reference to FIG. 4 for the selection of an album or a CD. That is to say, a title may once again be selected both by touching touch screen 11 and by a corresponding gesture, which is recognizable by gesture recognition module 5.
In the exemplary embodiment shown in FIG. 6, a map detail 60 is shown with the aid of display and operating device 4. Furthermore, operating elements 61, 62, 63, and 64 are shown, and touching of touch screen 11 in the region of correspondingly displayed operating element 61, 62, 63 and 64 shifts map detail 60 (in an upward, downward, left or right direction). For example, if touch screen 11 is touched in the region of operating element 62, then map detail 60—as shown in FIG. 7—is shifted in a downward direction.
In addition, map detail 60 is able to be moved in the same manner by gestures. For example, in response to a downward wave, map detail 60, as shown in FIG. 7, is shifted in the downward direction. In other words, downward waving elicits the same function as touching of touch screen 11 in the region of operating element 62. If waving in a direction toward display and operating device 4 occurs, then map detail 60, as shown in FIG. 8, is zoomed (shown in an enlarged view).
