Description

The present invention relates to a method for displaying information in a vehicle, wherein a vehicle-specific function of a device of the vehicle at least a first display element for a status display, which represents the state of the vehicle-specific function, and at least a second display element for an interaction display, which Users are supported, associated with an input. Furthermore, the invention relates to a device for displaying information in a vehicle with a display device for displaying display elements for at least one vehicle-specific function of a device of the vehicle and with a control device which is coupled to the display device and by means of which at least a first display element for a status display and at least one second display element for an interaction display, which assists the user with an input, can be generated for display by means of the display device, wherein the display elements are assigned to the at least one vehicle-specific function.

It is known to display, for a vehicle-specific function of a device of the vehicle, such as an adaptive cruise control, a status display which indicates the current status of this function. For example, as in 2 shown, a graphical symbol on a display surface of the vehicle shown, which is to indicate that the Adaptive cruise control is active. It is also known to assist the user in entering parameters for this vehicle-specific function through an interaction display. In 3 For example, an interaction screen is displayed that corresponds to the one in 2 The status display shown belongs. In this case, the user can enter how the time interval to the preceding vehicle is to be regulated.

Status displays are usually displayed at least when the corresponding vehicle-specific function is active. They are thus often displayed permanently. Since the available space on the display surfaces in a vehicle is very limited, status displays are usually represented by very small elements in a minimalistic way, as in 2 for the status display of the adaptive cruise control is shown. In contrast, interaction displays are only displayed graphically during the operation of a function, for example when a parameter is set, so that in this case graphic representations can be selected which require more space in order to be able to display in particular different selection alternatives. The status indicators and the associated interaction advertisements therefore often have only a slight formal similarity. As a result, it is often difficult for the user to assign the minimalistically displayed status displays to the associated vehicle-specific function or to associate the interaction display with the associated status display.

From the DE 103 037 92 A1 For example, a method for displaying vehicle-specific information signals is known. In this method, the vehicle-specific information is displayed in a three-dimensional representation on an on-board display device. Three-dimensional interactions or animations can also be started.

The present invention has for its object to provide a method and an apparatus of the type mentioned, by which the user in the display of the display element for the status display and / or in the display of the display element for the interaction display the assignment to the associated vehicle-specific function of the device the vehicle is facilitated.

According to the invention, this object is achieved by a method having the features of claim 1 and a device having the features of claim 8. Advantageous embodiments and further developments emerge from the dependent claims.

The inventive method is characterized in that in a display change in which initially only one of the display elements is displayed, for. B. the first display element for the status display, and then the information display is changed so that subsequently only the other display element, d. H. z. B. the second display element for the interaction display is displayed or both display elements are displayed, an animation is displayed, which establishes a relationship between the two display elements. In particular, successive frames are displayed during the animation, which gives the viewer the impression of a moving picture.

The animation displayed in the method according to the invention provides the user with a graphical uniqueness of the relationship between the display elements for the status display and the interaction display. As a result, the user can capture the respective display elements faster and more intuitively. He is thus visually better supported, especially when entering parameters for the vehicle-specific function of the device of the vehicle. The The use of the animation according to the invention also has the consequence that the driver of a vehicle less frequently has to avert his gaze from the driving situation in order to perceive and cognitively capture the display elements. Namely, so-called voting views are reduced between the two display elements.

According to one embodiment of the method according to the invention, one display element is transferred to the other display element during the animation. This animation technique is also referred to as visual morphing. In this case, successive intermediate images are calculated, which initially resemble more the originally displayed display element and finally more and more resemble the display element which is to be displayed after the display change.

According to another embodiment of the method according to the invention, the first display element for the status display is displayed in a first area and the second display element for the interaction display is displayed in a second area. In this way, a clear highlighting of an interaction area in contrast to status areas is produced on a display area in the vehicle. For display elements in the status area, the user does not expect manipulation of the vehicle-specific function; For display elements in interaction areas, the user knows that he can make inputs to vehicle-specific functions, where he is supported by display elements for interaction ads. In this case, for example, in animation, a movement of a display element from one area to the other area may be performed.

According to a development of the method according to the invention, a further display element or a display instrument is arranged between the two areas for the display element for the status display or the display element for the interaction display. In the case of the animation of the movement of the one display element from one area to the other area, a change in the display of the one display element to the other display element can be carried out in this case, depending on the relative position of the one display element to the further display element or the display instrument. This change can occur, for example, when the one display element touches the further display element or the display instrument or is displayed in the immediate vicinity of the further display element or the display instrument. Also, the display element during the movement of the other display element or the display instrument can be temporarily covered, wherein on one side of the movement, the one display element is displayed and on the other side, the other display element is displayed. As a result, the user can create a connection between the two display elements in a particularly simple and intuitive manner, even if they are displayed in different areas.

In particular, the second display element assists the user in entering a parameter for a vehicle-specific function of a device of the vehicle whose status is displayed by the first display element for the status display. The two display elements thus belong to the same vehicle-specific function.

The first display element is, for example, a two-dimensional graphic element. The second display element is in particular a three-dimensional graphic element or a perspective two-dimensional representation of a three-dimensional graphic element. If the second display element is displayed in three dimensions, the display is in particular autostereoscopic. In this case, in contrast to the perspective view, one eye of the observer sees a slightly different image than the other eye, so that a real three-dimensional representation is achieved. In an autostereoscopic display are no special devices such. As glasses or the like, necessary to cause the three-dimensional effect when viewing the display.

The inventive device for displaying information in a vehicle is characterized in that for a display change in which initially only one of the display elements is displayed and then the information display is changed so that subsequently only the other display element is displayed or both display elements are displayed, from the control device for display by means of the display device, an animation can be generated, in which a relationship between the two display elements can be produced.

The device according to the invention is particularly suitable for carrying out the method according to the invention described above. It therefore also has the same advantages as the method.

The operating element may be a mechanical operating element. This is arranged in particular on the steering wheel of the vehicle. Furthermore, the operating element may be a touch-sensitive surface of a display surface.

The operating element may be equipped with a touch sensor which detects when the user touches the operating element. After the detection of the touch, the control device initiates the display change from the first status-display display element to the interaction-display display element, in which case an operation intention is assumed. In this case, the operating element is associated in particular only with the corresponding vehicle-specific function of the device of the vehicle whose display elements are displayed.

Furthermore, the operating element can be equipped with a proximity detection device. This approach detecting device may detect an actuator, such as a user's finger, in a specific detection area in the vicinity of the operating element. If such an actuating element has been detected by the proximity detection device, it is assumed that an operating intent of the operating element and the display change is triggered accordingly by the control device.

In the two aforementioned embodiments, the transition from the display of the one display element to the display of the other display element for the user is very intuitive detectable. For example, if he wants to set a parameter of a vehicle-specific function, he moves his hand in the direction of the associated operating element. Once the user's fingertip has approached the control or has touched the control, an animation is displayed in which the status display indicator changes to the interaction display indicator which assists the user in entering the parameter. This animation is directly related to the beginning of the operation of the control, so that the user intuitively associates the started operation with the interaction display element. At the same time, the user can intuitively grasp to which vehicle-specific function the display element for the interaction display belongs, since the animation establishes a connection to the previously displayed display element for the status display of this vehicle-specific function.

According to a preferred embodiment of the device according to the invention, an autostereoscopic display can be generated by means of the display surface. For this purpose, a display which provides the display area, for. B. provided with a mask for the separation of various intermediate images. The mask is, for example, a wavelength-selective filter mask. This filter specifies the light propagation directions of the individual subpixels of the display by masking or filtering. Individual color values of the pixels are emitted at different angles into the room. In this way, separate images can be generated for the two eyes of the viewer, which are combined in the viewer to form a three-dimensional image. The image for one eye shows a slightly offset viewing position relative to the image intended for the other eye. Preferably, at least eight autostereoscopic views are simultaneously displayed, the views are radiatable in a horizontal viewing fan. It is preferably possible to produce several stereoscopic view compartments next to each other and to form a viewing zone. A total of six to eight adjacent autostereoscopic views are preferably included in the viewing compartments. The horizontal opening angle of the viewing fan or of the viewing compartments, in which an autostereoscopic display takes place, is preferably greater than 15 ° and in particular between 25 and 30 °. Particularly preferred is an opening angle of 27 °. In this way, multiple views at different viewing angles can be generated for the viewer, in each case correctly image pairs for the composition are emitted to a three-dimensional image at the respective angles. As a result, close to the display, you see two views that are farther apart. Going farther away, the partial views widen and the eyes see closer views. The number of views depends on the size of the display. For smaller displays whose diagonal is 4 inches, in particular eight views have proven to be favorable. For larger displays 16 or 24 views are possible.

The invention will now be explained by means of embodiments with reference to the drawings.

1 shows schematically the structure of an embodiment of the device according to the invention,

2 shows a display element for a status indicator according to the prior art,

3 shows a display element for an interaction display according to the prior art and the

4A to 4D illustrate an animation in a display change according to an embodiment of the inventive method.

In reference to 1 the basic structure of the embodiment of the device according to the invention for displaying information in a vehicle is explained:
The device comprises a display device 1 with a display area 2 , The display area 2 can be provided by a display, in particular a liquid crystal display or a plasma display, of any type. Furthermore, the display device 1 a head-up display or a head-down display, in which the display on a surface, such as the windshield projected.

The display device 1 is with a control device 3 coupled. The control device 3 can generate graphics data on the display area 2 can be displayed. Optionally, in front of the display area 2 a mask may be arranged to enable an autostereoscopic display. The mask is, in particular, a wavelength-selective filter mask or an optical structure mask. The mask makes it possible to distinguish between partial images belonging to different views and to radiate each view in a different direction. Thus, partial images for the right and left eyes of a viewer can be separated. When viewing the display area 2 For example, the drawing files can be combined into a three-dimensional view. For this purpose, no further aids such as glasses or the like are required. For further details of such a display device is on the DE 103 09 194 A1 and the DE 103 20 530 A1 which are incorporated by reference into the present application.

The separation of the partial images for the three-dimensional image is possible only in a certain solid angle. For example, if the viewer moves sideways in a horizontal plane, the separation of the subpictures is canceled and the representation becomes two-dimensional. In order to generate as many picture pairs as possible for a correct three-dimensional representation in the room, several views are shown for a display picture. The partial images of these different views are radiated approximately fan-shaped horizontally, so that forms the horizontal viewing fan. The opening angle of a viewing fan is z. B. 27 °. It turns out that eight views on a 4-inch display area 2 are particularly preferred. In this case, the brightness, resolution and spatial reproduction are sufficient. The resolution of the display area 2 in this case is greater than 150 dpi.

Furthermore, the device comprises an operating element 4 connected to the control device 3 is coupled. In the present embodiment, it is the operating element 4 around a mechanical control 4 , such as a rocker switch 4 , which is arranged on the steering wheel of the vehicle. Furthermore, the operating element 4 be a turn-push-dial. The mechanical control is z. B. equipped with a touch sensor that detects when the user touches the control element.

Instead of the mechanical operating element or in addition to the mechanical operating element can also on the display surface 2 a touch-sensitive surface can be provided, via which the user can make inputs. In this case, a so-called touch screen is provided. By means of the control element 4 the user can make inputs to vehicle-specific functions, in particular set parameters for such functions.

Furthermore, in the environment of the control element 4 an approach detection device 13 provided, which with the control device 3 is coupled. The approach detection device 13 For example, it can comprise a reflection light barrier which comprises at least one light source for emitting electromagnetic detection radiation into a detection area and a reception element for detecting a portion of the detection radiation which is scattered and / or reflected by the actuation element. In particular, it can be configured to recognize the actuating element in the detection area on the basis of the intensity of the received detection radiation. The approach detection device 13 may further comprise different light sources for individual detection zones, each of which emits electromagnetic detection radiation into the respective detection zone. Furthermore, a modulation device for modulating the emitted detection radiation may be provided, so that the detection radiation which is emitted into the individual detection zones differs in each case with regard to their modulation. In this case, the approach detection device 13 also comprise an analysis unit which is designed such that the received reflected and / or scattered detection radiation can be analyzed with regard to its modulation in order to determine in which detection zone the detection radiation was scattered or reflected at an actuating element. By means of approach detection device 13 Thus, the residence of an actuator can be determined separately for each detection zone.

If the display area 2 provided with a touch-sensitive surface to a control element 3 can provide the proximity detector 13 also at the display area 2 be arranged to form a detection zone, by means of which an approximation of an actuating element to the touch-sensitive surface on the display surface 2 can be detected.

The control device 3 is further with a data bus 5 coupled to the vehicle, in turn, with at least one device 6 of the vehicle is coupled. In the present embodiment, the device is 6 a driver assistance system 6 in particular comprising a module for an adaptive cruise control, which automatically regulates the distance to a preceding vehicle as a vehicle-specific function. Such a distance control is known per se.

To visualize the user of the state of the driver assistance system or the adaptive cruise control is on the display surface 2 as a status display, a first display element 10 shown, as will be explained later. Furthermore, by the control device 3 a second display element 12 generated on the display surface 2 can be displayed to the user when entering parameters using the control 4 to support. The second display element 12 thus provides an interactive message for z. B. a driver assistance system ready.

The following is related to the 4A to 4D explains how the ad is displayed on the screen 2 changed according to an embodiment of the method according to the invention:
As in the 4A to 4D shown is the display area 2 a freely programmable display area of the instrument cluster of the vehicle. On the display surface 2 will also be round instruments 7 and 8th displayed for the speed and speed display of the vehicle. Alternatively, these round instruments can also be used, in part, as physical display instruments of the display area 2 be superimposed arranged. Inside the round instrument 7 is a display area 9 formed in which display elements 10 for a status display vehicle-specific functions of the facilities 6 the vehicle are displayed, ie in the present case, the display element 10 for the status display of the driver assistance system 6 , Between the two round instruments 7 and 8th is another display area 11 formed, in which display elements 12 for an interactive ad. The interaction display supports the user when entering parameters for the driver assistance system 6 ,

It is initially assumed that the adaptive cruise control and, where appropriate, further modules of the driver assistance system are active. This is done by the display of the display element 10 in the display area 9 visualized in the instrument cluster of the vehicle.

Will now be using the approach detection device 13 detects that the user's fingertip is the control element 4 approximates which the driver assistance system 6 is assigned, a display change from the control device 3 generated, in which - as in 4A shown - initially only the display element 10 is displayed for the status display and then - as in the 4B to 4D shown - the information display is changed so that finally only the display element 12 for the interactive display for setting a parameter of the driver assistance system 6 is shown. At the transition from the presentation according to 4A to the representation according to 4D An animation is displayed showing the relationship between the two display elements 10 and 12 manufactures.

As in 4B shown, first, the display element 10 for the status display in the direction of the display area 11 moved for the interaction ad. In the area of the display or the elements of the round instrument 7 disappears the display element 10 and finally dives like in 4C shown in the display area 11 back up. However, in the display area 11 no longer the display element 10 for the status display, but the associated display element 12 for the interaction ad. This will take you to the middle of the display area 11 move until the animation according to the display 4D ends. The user can now use the control 4 an input to the vehicle-specific function of the driver assistance system 6 make, for example, a parameter of the adaptive cruise control can be set. For example, this parameter may be in the display element for the user 12 be displayed for selection, so that when entering from the display element 12 is supported.

If the user after the completion of the operation his hand back from the control 4 This is done by the proximity detector 13 detected. After a defined time interval, an opposite animation will be triggered. The display element 12 for the interaction display thus moves in the direction of the display area 9 , disappears behind the display for the round instrument 7 or behind the physical element of the round instrument 7 and finally appears in the display area 9 again as an indicator 10 for the status display. Has the status of the institution 6 changed by the input, also a correspondingly changed display element appears 10 for the status display.

As in 4A shown, it is the display element 10 around a two-dimensional graphic element, which by circle segments the state of the driver assistance system 6 visualized. The second display element 12 includes a perspective view of the vehicle from a bird's eye view from behind, which of Circular segments is surrounded, showing the state of the driver assistance system 6 determine the vehicle. The of the display element 12 Circular segments shown can be selected by the user by an input by means of the operating element 4 be changed, thereby increasing the settings of the driver assistance system 6 change.

If the display device 1 An autostereoscopic three-dimensional display allows the display element 12 also be rendered as a three-dimensional graphic element, which is in front of the display area 2 floats.

According to a further embodiment, the position of the display element 10 or the display element 12 not changed. Instead, the animation element becomes the display element 10 in the display element 12 transferred and vice versa. Also in this case, the user can through the animation a relationship between the two display elements 10 and 12 produce.
