Description

The invention relates to a method for presenting display content and a display system.In a motor vehicle, information is displayed to the driver via a combination instrument. A classic instrument cluster consists of round instruments with pointers, which are usually driven by stepping motors, displays for displaying text and graphics and control lights for various warnings. Furthermore, three-dimensional displays are known, for the use of which special spectacles were required.The document DE 10 2011 006 428 A1 describes a device and a method for operating a freely configurable display combination instrument in a vehicle.A virtual three-dimensional instrument cluster is known from the publication EP 2 896 531 A2.A transparent virtual instrument cluster with live video is known from the publication EP 2 914 002 A1.US 2018 / 0005434 A1 describes a system and a method for interactive display of a hybrid-dimensional map, which also comprises a two-dimensional and a three-dimensional map.A method for displaying visual information in a navigation system is known from the publication US 2014 / 0267282 A1.The document DE 10 2013 016 244 A1 describes a method for augmented presentation of at least one piece of additional information in at least one image of a vehicle environment.Against this background, it was an object to present a representation of display content to a user of a vehicle in a suitable manner.This object is achieved by a method and a display system having the features of the independent claims. Embodiments of the method and display system will be apparent from the dependent claims and the description.The method according to the invention is provided for displaying a display content, for example traffic-related display content, which is provided by a navigation device, wherein the display content provided by the navigation device is displayed two-dimensionally to a first extent and three-dimensionally to a second extent on a display panel of a motor vehicle. In this case, a current position of the motor vehicle is detected by the navigation device, wherein the first portion for which the display content is displayed or displayed two-dimensionally and the second portion for which the display content is displayed or displayed three-dimensionally are set depending on the current position of the motor vehicle.In one embodiment of the method, the display content is displayed by the display field or a corresponding display of a cluster instrument of the motor vehicle in a position-dependent or location-dependent two-dimensional and / or three-dimensional manner. Taking into account the respective position of the motor vehicle at which it is located during a trip, a respective environment which comprises the position and in which the motor vehicle is located is also taken into account. The display content to be displayed usually comprises a plurality of display elements, which are determined by the navigation device as a function of position and are taken into account and / or proposed for display on the display panel. A decision as to which first portion of the display content or display elements is or are displayed two-dimensionally and to which second portion of the display content or display elements are displayed three-dimensionally also depends, for example, on a set of potentially displayable display elements at a respective position of the motor vehicle and / or the environment in which it is currently located at the respective position.The method takes into account, on the basis of the detected position, where the motor vehicle is currently located in each case. In this case, the respective current position is located on a ground on which the motor vehicle is travelling, usually a road, wherein the position and / or the ground is correspondingly surrounded by an environment. Objects, usually buildings, buildings, bodies of water and / or vegetation, i.e. plants, are located in this environment, for example. Trees. Objects of this type from the current environment of the motor vehicle are selectively displayed two-dimensionally or three-dimensionally on the display panel, wherein in each case one object forms a display element and all display elements form the display content which can be selectively displayed or is to be displayed two-dimensionally or three-dimensionally. In this case, the navigation device accesses a database, which can be designed as part of a server, wherein the navigation device communicates wirelessly, generally with radio assistance, with the database and / or the server.A display element, which represents an object in the respective current environment of the motor vehicle, is taken over from the database by the navigation device and is displayed two-dimensionally or three-dimensionally depending on the position. In this case, a position-dependent density of objects and display elements which represent them is also taken into account. The greater the density, the more display elements are displayed three-dimensionally. This facilitates orientation in the current environment. In this case, a degree of a density of the objects is to be determined, for example on the basis of a number of objects per area in a respective environment.If the density of the objects, for example their number per area, exceeds a definable and / or defined threshold value, a respective object and thus a display element for representing this object is displayed three-dimensionally on the display panel. If the density of the objects, for example their number per area, is less than the threshold value or at most equal to the threshold value, a respective object and thus a display element for representing this object is displayed two-dimensionally on the display panel. In this case, the environment can have a plurality of regions or be divided into a plurality of regions or be divided by the navigation device, depending on the current position. In this case, it is possible to represent objects from a first area of the environment in which the density of objects is greater than the threshold value in a three-dimensional manner. At the same time, it is possible to represent objects from a second area of the environment, in which the density of objects is less than the threshold value or at most as great as the threshold value, two-dimensionally.In one embodiment, an urban area that is densely built and has a density of objects, in particular buildings, that is greater than the threshold value is displayed or reproduced three-dimensionally. In contrast, a rural area that is sparsely built up, wherein the density of objects, in particular buildings, is lower than the threshold value or at most as large as the threshold value, is displayed two-dimensionally.As a rule, a respective environment encloses the current position of the motor vehicle by 360°, wherein the environment is divided into different areas with different density of objects. A respective region is defined and / or taken into account starting from the current position and depending on an angle-dependent perspective according to which it is arranged in the environment.By means of an optionally two- or three-dimensional display of the display content and thus of display elements which represent objects in the environment of the motor vehicle, it is possible with the display on the display panel inter alia to assist a driver of the motor vehicle in an orientation at a respective position and in a respective environment.In one embodiment, it is provided that the second portion corresponds to the complete display content minus the first portion. In this case, the first portion comprises first display elements and thus first objects to be represented thereby from the environment, which are displayed two-dimensionally, and the second portion comprises second display elements and thus second objects to be represented thereby from the environment, which are displayed three-dimensionally.Thus, the display panel usually displays a plurality of display elements which are detected by the navigation device as a function of position and environment and are provided from the database. In this case, it is possible for a quantity of display elements to be displayed or displayed depending on the position to vary depending on the position. In one embodiment of the method, it is decided, inter alia, which display elements and thus which respective portion of display elements of the display content are displayed two-dimensionally or three-dimensionally. It is conceivable here that the complete display content and thus all display elements are displayed only two-dimensionally or only three-dimensionally. Apart from this, the first portion for two-dimensional display of the display content and the second portion for three-dimensional display of the display content are determined as a percentage depending on the position. It is possible to generate a corresponding optical 3D effect depending on the position for the three-dimensionally displayed display content. The display panel used has a surface for displaying the display content. According to the two position-dependently set portions, the display content is displayed two-dimensionally on a first surface of the display panel which corresponds to the first portion, and the second display content is displayed three-dimensionally on a second surface of the display panel which corresponds to the second portion in terms of area.In one embodiment, an amount of information to be displayed by the display panel or an information density and / or an amount of information, for example, is displayed. The object density is determined as a function of the current position of the motor vehicle, wherein the first portion and the second portion are set as a function of the amount of information. In this case, the second proportion is set to be larger the larger the amount of information to be displayed or the quantity of display elements to be displayed. Accordingly, the larger the information amount to be displayed, the lower the first portion is set. In this case, it is possible for the position- and / or environment-dependent range of information to be correlated with the set of display elements which can be displayed overall as a function of position and which are provided by the navigation device.In one embodiment, the first portion and the second portion are additionally manually adjusted at a respective position or a respective location by a user of the motor vehicle and are thus more precisely adjusted depending on the user. In this case, an additional manual adaptation of the first portion and the second portion, which is carried out by the user at the respective position within the scope of the method, is learned, for example, by a computing unit used in the method, carrying out a learning algorithm, usually using artificial intelligence, in order to directly set the first and second portions desired by the user in the future, given the same respective position or the same respective location and thus the same environment. In this case, it is taken into account that, first of all, the navigation device automatically decides which region and which objects located therein are displayed two- or three-dimensionally, for example on the basis of objects in the region of the environment and / or the density of objects per area in the region and taking into account the threshold value. However, a correspondingly proposed representation by the navigation device is adapted by the driver in one embodiment, wherein it is possible, for example, for the threshold value provided to be individually adapted and thus changed by the driver depending on a respective environment, for example depending on a respective area in the environment. Such an adaptation is noticed by the learning algorithm area- and / or environment-dependent as well as depending on the current position of the motor vehicle and thus learned and taken into account if the motor vehicle is again in the same or a very similar environment in the future.In one possible embodiment of the method, it is taken into account that in each position in which the motor vehicle can be located and thus in a respective environment in which it is located, the amount of information and thus usually the amount of potentially representable display elements varies depending on position or environment. If, for example, a first value is determined for a first position as a function of the quantity of display elements for the first portion for the display content to be displayed two-dimensionally and a second value for the second portion for the display content to be displayed three-dimensionally, wherein the two values total 100%, it is possible that the same values are automatically set for the two portions at a further second position for which the same quantity of display elements as for the first position is determined.In one embodiment, the environment of the motor vehicle and thus the environment in which it is located is optically captured by at least one sensor, for example a camera, of the motor vehicle and is displayed on the display panel, wherein a display of the environment is supplemented by the display content of the navigation device. In this case, it is possible to superimpose the display content or the display elements of the navigation device in accordance with a respective position-dependent proportion in the environment captured by sensors and thus in the representation or in an image of the environment for this purpose.In a further embodiment of the method, a distinction is automatically made between important display elements or important display details, i.e. important objects, on the one hand, and unimportant display elements or unimportant display details, i.e. unimportant objects, on the other hand. In this case, it is possible for an importance of a respective display element to be taken into account by a traffic situation in which the motor vehicle is located at the respective current position. This relates to both a current traffic situation which prevails at the point in time at which the motor vehicle is currently located at the position and any predictable or predicted future traffic situations in which the motor vehicle will be located at other positions in the future. In this case, an important display element for displaying an important traffic situation is displayed on the display panel in front of an unimportant display element for a comparatively unimportant traffic situation, with the result that the unimportant display element is nevertheless displayed in a recognizable manner behind the important display element. An importance of a display element and thus of an object in the environment depends, inter alia, on how marked and / or conspicuous the display element or the object to be represented thereby is, the importance thereby depending, for example, on how much it assists the driver for orientation in the environment. It is possible here for such important objects which are particularly suitable for orientation to have, for example, a particular recognition value, to be defined accordingly in the database which the navigation device accesses. In this case, it is possible for the driver to customize the database as a user and to define specific objects as important objects which are displayed three-dimensionally or as unimportant objects which are displayed two-dimensionally.The display system according to the invention is designed for a display panel of a motor vehicle, usually in an interior of the motor vehicle. The display system has a navigation device for the motor vehicle or the motor vehicle, wherein the navigation device is designed to provide a display content, for example a traffic-related display content, to the display field, wherein a display field of the motor vehicle is designed to display the display content provided by the navigation device two-dimensionally to a first portion and three-dimensionally to a second portion. The navigation device is furthermore designed to record a current position of the motor vehicle in each case, wherein the display panel is designed to set the first portion, at which the display content is to be displayed two-dimensionally, and the second portion, at which the display content is to be displayed three-dimensionally, depending on the current position of the motor vehicle.In one embodiment, the display system has a computing unit, wherein the navigation device is designed to provide information about the display content to be displayed and the current position of the motor vehicle to the computing unit. Taking into account and / or depending on the current position of the motor vehicle, the computing unit is designed to determine which first portion the display content is to be displayed two-dimensionally and which second portion the display content is to be displayed three-dimensionally and to actuate the display panel on the basis thereof. It is possible to carry out an embodiment of the presented method with an embodiment of the presented display system. In one embodiment, the display panel is adjusted by the computing unit in a two-dimensional and three-dimensional manner in accordance with the current position of the motor vehicle and thus the environment in which it is located, and optionally also in accordance with the quantity of display elements and thus the amount of information, wherein values for a size of the two portions are determined by the computing unit, preferably in real time.The display system is usually designed for a display panel of a cluster of the motor vehicle, wherein the display panel or a corresponding display or a corresponding monitor is designed as part of this cluster of the motor vehicle. This instrument cluster has the three-dimensional display field. In an alternative embodiment, it is possible that a windshield or front screen of the motor vehicle is also used as a display field, wherein the display content to be displayed two-dimensionally and three-dimensionally depending on the position is projected onto the front screen. With the display panel, it is possible to display any desired display content, even independently of the presented method. It is thus possible to use the display panel as a full display instrument to also display a classic instrument cluster made of round instruments with pointers, which are generally driven by stepping motors, and to copy them optically, wherein it is also possible to display text and graphics and control lights for various warnings. In this case, a classic division of the display content of such a classic instrument cluster in the surface is maintained. The display panel is usually controlled with software assistance. In this case, a basic version of the display panel is to be used, inter alia, for different instrument clusters or models of motor vehicles, it being possible for the display content to be adjusted individually with software for each instrument cluster and / or model.The display field or a corresponding three-dimensional display can be used, for example. In this case, pointers for a respective round instrument can be represented spatially in front of the respective round instrument. Accordingly, important display elements can also be spatially placed in the foreground and less important display elements can be placed or positioned further in the background. In this case, it is possible for a respective representation or fractional division of the two-dimensional and three-dimensional display content to be additionally set and thus adapted, for example, by the driver as a user of the motor vehicle himself. In this case, it is possible, for example, to display a warning display as particularly important display content on the display panel in the foreground and thus to have it appear suddenly there or to pop it into the foreground if a warning is to be provided against a traffic situation and / or a warning is to be made about this traffic situation. It is also possible to display a three-dimensional navigation map three-dimensionally on the display panel. In this case, a corresponding display of a navigation screen can also be displayed in an extended manner on the display field. Within the scope of the method, it is furthermore possible to vary a spatial depth of the display content and / or of the display elements and thereby provide a maximum depth or a minimum depth or zero depth for a respective display element and display the display element in a corresponding spatial plane on the display field.In a further embodiment, it is possible to capture the environment of the motor vehicle using at least one sensor, for example a camera, which can generate three-dimensional images, and to supplement a corresponding representation of the environment by the display content of the navigation device. The at least one sensor can be arranged on a front, on a side or on the rear of the motor vehicle, wherein a respective sensor can be embodied or designated, for example, as a forward camera or as a rearward camera. In a further embodiment, it is also possible to spatially divide the display field or display and to display the display content, for example, spatially shared, partially two-dimensional and partially three-dimensional. This results inter alia in the user of the motor vehicle being provided with the display field with a more realistic optical display behavior.When using the method and / or the display system, 3D eyeglasses are not required for viewing the display content.By position-dependent setting and variation of the display content to be displayed two-dimensionally and of the display content to be displayed three-dimensionally, it is possible, inter alia, to enhance or mitigate a 3D effect, wherein this 3D effect is all the more pronounced the higher or the larger the second proportion is. In one possible embodiment, it is possible to use the method when the motor vehicle is travelling on a freeway, wherein the motor vehicle is located at a position on the freeway. In this case, it is possible to display the display content three-dimensionally only to a small second portion and thus two-dimensionally to a larger first portion, since a displayable amount of information or information content is comparatively small in the case of the freeway or possibly also on a country road. If the motor vehicle is currently located at a position in a highly populated and / or populated environment, for example in an ambiguous city area with many high houses, for example also cloud scratches, it is provided to enlarge the display content for better orientation by position-dependent setting and / or enlarging the second portion for three-dimensionally displaying the display content and thus enrich it. In the method, it is decided by means of the navigation device as a function of position or as a result of location when the second portion is increased or decreased compared to the first portion, wherein the 3D effect is correspondingly increased or decreased. By a respective proportional two- and three-dimensional display of the display content, a navigation display on the display panel can be adjusted depending on the position. Furthermore, an expansion by augmented reality is also possible, wherein images, for example. Image sequences with the at least one camera, for example. 3D camera, from which the environment is recorded and, depending on the position, can be displayed or represented two-dimensionally or three-dimensionally for a respectively provided portion. Such a representation can be used for navigation of the motor vehicle, but also, for example, as a parking aid during parking.As described above, the first portion and the second portion are first set by the navigation device as a function of position. In addition, it is possible for the driver as a user of the motor vehicle to reinforce or attenuate the 3D effect. In this case, it is possible for the display system to learn in which situation the two components are adapted by the user, for example by using artificial intelligence and / or a neural network, wherein such an adjustment is adapted, wherein it is possible to automatically predict such a manual adjustment that is otherwise to be carried out by the user in the future.It is understood that the features mentioned above and those still to be explained below can be used not only in the respectively specified combination, but also in other combinations or alone, without departing from the scope of the present invention.The invention is schematically illustrated in the drawing on the basis of embodiments and is described schematically and in detail with reference to the drawing.

It is also possible for the display panel 9 to be formed as a component of the display system.When carrying out the embodiment of the method according to the invention with the display system presented here, it is provided that the navigation device 4 determines a display content which can be displayed or displayed on the display panel 9. Furthermore, the current position 10 of the motor vehicle 2 is determined here, wherein here it is determined by the computing unit 6 as a function of position, to which first portion 12 the display content of the navigation device 4 is displayed two-dimensionally and to which second portion 14 the display content of the navigation device 4 is displayed three-dimensionally with the display panel 9 or on the display panel 9. As indicated in FIG. 1, it is possible for the display panel 9 to be spatially divided, wherein the two-dimensional display content is displayed on the first portion 12 of a surface of the display panel 9 and the three-dimensional display content is displayed on a second portion 14 of the surface of the display panel 9.In this case, it is possible for the motor vehicle 2 to be located in a specific environment surrounding the current position 10 of the motor vehicle 2. This environment is displayed on the display panel 9. Objects from the environment are thereby selectively represented by the navigation device 4 as two- or three-dimensional display elements by and / or with access to a database on the display panel 9, wherein a display element represents an object, for example a building or a building, from the environment. In this case, in one embodiment, it is taken into account how closely the objects are arranged in the environment, it being possible to take into account a density of objects per area in the environment. In this case, the environment is automatically divided into different regions which differ with respect to a density of objects. The navigation device 4 likewise assumes a respective density of objects per area by accessing the database. A respective density per region is compared with a definable and / or to be defined threshold value. If the density in a first region is less than or at most as great as the threshold value, this first region is displayed two-dimensionally on the first portion 12 of the surface of the display panel 9. If the density in a second region is greater or higher than the threshold value, this second region is displayed three-dimensionally on the second portion 14 of the surface of the display panel 9.REFERENCE NUMERALS:2 Motor vehicle 4 Navigation device 6 Computing unit 8 Instrument cluster 9 Display field 10 Position 12, 14 Portion
