Description

The present invention relates to a method and a device for displaying information on a screen of a navigation device, the information to be displayed including map information and additional information superimposed on the map information.

Today, navigation devices for route guidance are made available to road users in a large number of different end devices, such as, for example, on mobile telephones, tablet computers, special portable navigation devices or also on end devices permanently installed in a vehicle. In motor vehicles today, navigation devices are mostly an integral part of the driver information system. The navigation devices have one or more graphical user interfaces, hereinafter referred to as displays, screens or displays, on which different information can be displayed. The main information of a navigation device is the map information, which typically consists of a scalable two-dimensional or perspective-modulated, quasi three-dimensional map or corresponding satellite images or a superimposition of a graphic map and satellite images. The map display is usually centered according to the position of the navigation device, which is usually determined by means of a satellite navigation device of the navigation device. Various types of additional information can be superimposed on the pure map information on the screen of a navigation device. If route guidance is activated in the navigation device, the highlighting of the calculated route on the map material represents additional information closely linked to the map information. Another class of additional information closely linked to the map information represents guidance information for the route guidance, for example turning instructions, detailed animations of more complex ones Road situations, such as traffic gyros, multi-lane route guidance, etc. Guide information for route guidance can often be output graphically, acoustically or as a combination of graphical and acoustic information. In addition, the additional information includes city names, street names, water names, and so-called points of interest (POIs), which are typically represented using suitable icons, such as petrol stations, workshops, parking lots and parking garages, ATMs, hotels, sports stadiums, cinemas, museums, Sights and leisure activities. Additional information can also include weather information, in particular temperature or precipitation information, brief information on places of interest or the opening times of various POIs.

In motor vehicles, navigation devices are also now mostly part of a complex driver information system, the screen or screens of the driver information system not only being used to display the screen information of the navigation system, but also displaying a wide variety of information from the driver information system, for example multimedia information, information from the air conditioning system, information about the vehicle status and much more. Particularly when the map display of the navigation device is displayed as a background image in the full screen mode, map information is covered by a large number of information windows and icons that have no direct connection to vehicle navigation.

Modern navigation devices usually have a settings menu in which the preferences of the user, for example via the type of output of the guidance information or the secondary information to be displayed, can be specified from the driver information system.

For particularly ergonomic use, modern navigation devices have a so-called auto-zoom function, in which the magnification scale (zoom level) of the map information can be changed automatically depending on the situation. For example, when traveling at a higher speed without imminent changes to the road or lane, a small magnification scale is selected so that a larger area around the position of the user is visible on the screen for a better overview. As the speed of the user decreases, the magnification scale is usually increased to show more details in the immediate vicinity of the user, especially when a change of direction, such as a turn into another street, or a more complex traffic situation, such as a traffic circle, immediately is imminent.

Under certain circumstances, the large number of possible additional information can impair the use of the map information and the guidance information when guiding the route, since the user can often have difficulties in filtering the information that is actually of interest to him from the large number of information presented. Numerous measures have therefore already been proposed for adapting the information to be displayed to specific situations.

So describes the DE 10 2004 043 861 A1 a system for adaptive route guidance, in which the presentation concept of the guidance notes is changed depending on a driving situation model. The driving situation model forms the whole Situation in and around the vehicle, into which the condition of the vehicle, the behavior of the driver, but also possible driver intentions are incorporated. Different presentation concepts are, for example, a street-based presentation concept in which the guidance is primarily adapted to the type of road or an information density-oriented presentation concept that is based in particular on the number of striking route points that appear next. It is also mentioned that the display concept can be selected either automatically or by the driver.

In the DE 10 2014 203 665 A1 a so-called score system is described, which defines which labeling elements are displayed in a navigation system at what time. This means, for example, that superfluous information such as sights can be hidden immediately before a turning situation.

In DE 10 2006 038 551 A1 A comparable proposal is described in which the relevance of object information to map data is determined with respect to the currently used route section and, depending on this relevance, object information is either displayed or not displayed.

DE 10 2012 023 481 A1 describes a method for improved spatial perception of displayed map material by spatial plasticity on the basis of height information, it being proposed to display or not to display information such as city names, river names or streets in each case depending on the zoom level mentioned.

Also in the DE 11 2013 002 790 T5 describes a method for 3D map display by animated movement of a virtual camera, the map display and the information displayed being dependent on the zoom level.

In many cases, the automated methods described in the prior art can ensure that in certain situations the user's attention is directed, for example, to guidance for route guidance and distractions are avoided by unnecessary additional information at this moment, but automated systems can meet the actual need for information Predict users insufficiently at any moment. In addition, the prior art does not suggest any solutions for additional information that does not originate from the navigation device itself, but rather is represented as additional information independent of navigation from the driver information system.

There is therefore a need for a method and a device for displaying information on a screen of a navigation device that reliably enables the user to reduce additional information on the screen of the navigation device at a desired moment.

This technical problem is solved by the method according to the present claim 1 and the device according to the present claim 10. Advantageous further developments of the invention are the subject of the dependent claims.

The invention accordingly relates to a method for displaying information on a screen of a navigation device, the information shown including map information and additional information superimposed on the map information. The method according to the invention is characterized in that the influence of certain additional information on the visibility of the map information is reduced if the magnification scale of the map information is changed manually.

The invention is therefore based on the consideration that the navigation device is by default in a mode in which either an automatic, situation-dependent adjustment of the magnification scale of the map information takes place, which the user can at least temporarily cancel through the manual intervention, or that the map is in is a fixed magnification scale predetermined by the user, which the user can also change manually. According to the invention, it is now proposed to use the manual user intervention to change the magnification scale as an indication that the user is particularly interested in the data provided by the map information, so that at this moment certain additional information is of less interest. According to the invention, it is therefore proposed to reduce the influence of certain additional information on the visibility of the map information accordingly.

“Influence on the visibility of the map information” is understood to mean that the additional information superimposed on the map information covers the map information behind the additional information. A reduction in the influence of the additional information on the visibility of the map information in the context of the method according to the invention therefore consists primarily in a reduction in the area-related proportion of the additional information which Card information covered. This can be done in many different ways.

According to one embodiment of the invention, the specific additional information is minimized, for example by points of interest being symbolized only with small symbols instead of with lettering or even only with unlabeled points. Additional information from the driver information system can, for example, be minimized in that instead of a media window, information about the artist and title of a song currently being played is only displayed as a small symbol, which symbolizes that a media offer is currently active.

Alternatively or additionally, the specific additional information can also be presented at least partially transparently. Partial transparency can be realized in different ways, for example by certain additional information only being symbolized as outlines and / or the particular additional information being shown translucently so that the map information behind it becomes visible.

According to a particularly preferred embodiment, the specific additional information is hidden.

The measures for reducing the influence of the specific additional information on the card information can be used individually or in combination, for example certain additional information can be completely hidden, while other additional information is minimized and other additional information is shown partially transparently.

Not all additional information is preferably treated equally in the method according to the invention. The individual additional information available is particularly preferably subdivided into at least two display groups, the influence of at least one of the display groups on the map being reduced when the magnification scale is changed manually. If, for example, non-navigation information from the driver information system is displayed regularly, it can be assumed that if the magnification scale of the map information is changed manually, this non-navigation information is currently uninteresting and can be minimized or hidden. This non-navigation additional information can therefore be divided into a display group to be hidden, while additional information relevant to navigation is divided into a display group that is still to be displayed. But also the navigation-relevant additional information can be divided into additional information to be hidden and not hidden. For example, the route can be additional information that you do not want to hide even if you manually change the magnification of the map information, while additional information such as arrival time, points of interest, etc. are hidden in order to ensure a clearer map display.

A setting menu of the navigation device can then be used, for example, to specify in which display groups the influence on the map display is to be changed and in what manner or not.

The behavior of the respective display groups can also depend on whether the magnification scale is enlarged or reduced manually. If the image scale is enlarged, it is assumed that the user is interested in more detailed information in his immediate surroundings. In this case, you can hide additional information such as city names, for example, but leave street names and points of interest such as parking lots, petrol stations and the like visible. If the magnification scale is reduced, it can again be assumed that the user is interested in an overview impression of the wider area, so that in this case, for example, street names can be hidden, but city names and / or sights cannot be hidden. The behavior when enlarging or reducing the magnification scale can preferably also be configured individually in the settings menu of the navigation device.

The reduction in the influence of certain additional information on the visibility of the map information is preferably ended automatically. For example, this reduction in influence can only take place temporarily, so that the reduction in influence is ended automatically after a certain time interval. Alternatively or additionally, it can be provided that the reduction in the influence of the specific additional information on the visibility of the map information takes place depending on the situation. For example, it can be provided that guidelines, such as turning arrows and the like, are initially hidden when the magnification scale is changed manually. If, however, a turning situation according to route guidance is imminent, it can be provided that the corresponding guidance is displayed, even if the specified time interval for the automatic end of the reduction in influence has not yet expired. Of course, it can also be provided that the reduction in the influence of the specific additional information on the card information at any time can be ended manually, for example by pressing a corresponding push button.

The invention also relates to a navigation device with at least one screen for displaying map information and additional information superimposed on the map information, at least one actuating device for manually setting the magnification scale of the map information and a control device for controlling the display of the map information and the additional information. The navigation device according to the invention is characterized in that the control device is set up to carry out the method according to one of claims 1 to 9.

The actuating device for manual setting of the magnification scale is to be interpreted very broadly here, whereby “manual” is to be understood here in particular as a contrast to “automatic” and should not necessarily be limited to manual or even mechanical setting. Often a manual adjustment of the magnification scale will take place by means of suitable mechanical rotary knobs or setting wheels, which are typically installed in the center console or in the steering wheel, but a manual change of the magnification scale can just as well be done via a touch-sensitive or proximity-sensitive display of the navigation device or a separate touchpad typically in turn can be installed in the center console or in the steering wheel. In the case of a voice-controllable navigation device, the magnification scale can also be set manually using corresponding voice commands.

The navigation device preferably also has an actuating device for ending the manual setting mode for the magnification scale. For example, the above-mentioned rotary knob or the setting wheel can be provided with an additional push function for deactivating the manual setting mode of the magnification scale.

The method and the device according to the invention are preferably used in motor vehicles, in particular if the navigation device is part of a driver information system of a motor vehicle.

The term additional information should therefore be interpreted broadly in the present context. The screens of modern driver information systems of a motor vehicle are typically not only used to display information from the navigation device of the vehicle, but also offer a graphical user interface for numerous other vehicle information items which can be superimposed on the navigation window in many display modes. This includes, for example, information from the vehicle's multimedia system, the vehicle's air conditioning system and similar information that is completely independent of the navigation device.

• 2a eine schematische Darstellung des Bildschirms des Fahrerinformationssystems der 1 mit eingeblendeten Zusatzinformationen; und
• 2b eine schematische Darstellung des Bildschirms der 2 mit ausgeblendeten Zusatzinformationen.

The invention is explained in more detail below on the basis of a very schematically illustrated exemplary embodiment. Show:

• 1 an interior view of a motor vehicle;
• 2a is a schematic representation of the screen of the driver information system of the 1 with additional information displayed; and
• 2 B a schematic representation of the screen of the 2nd with hidden additional information.

In 1 is the interior view of a motor vehicle 10 shown. The car 10 includes a center console 11 in which a screen 12th a driver information system / infotainment system not shown in more detail 13 is installed. The driver information system 13 includes a navigation device, which maps and route guidance on the screen 13 displays. Below the screen 12th is schematically a rotary / push button 14 arranged for manual adjustment of the magnification scale of the map display. As explained above, this rotary knob is only to be understood as representative of a wide variety of input options for changing the magnification scale. Corresponding controls for manually setting the magnification scale of the map display can also be found in the steering wheel, for example 15 be installed or can even be realized as a gesture or voice control, not shown.

2nd shows the screen 12th of the driver information system 13 of the 1 schematically in the two display modes according to the invention.

It shows 2a shows a schematic representation of the screen 12th with activated navigation view, ie a large part of the screen 12th or in full screen mode the entire screen is also with map information of the navigation device of the driver information system 13 filled. The basic map information includes roads, for example 16 , Locations, bodies of water, as well as a typically centrally arranged vehicle symbol, not shown here, which represents the location of the vehicle on the map. As shown, the map display is a lot of additional information 17th , 18th overlaid either by the Navigation device or can come from other data sources of the driver information system. In the display mode of the 2a an automatic setting of the magnification scale is activated, which is indicated by a corresponding scale symbol 19th can be displayed, which indicates the automatic function.

When the driver turns the knob 14 operated to manually change the magnification scale of the map display, this is done by the corresponding control device of the navigation device or the driver information system 13 as an indication that the driver is currently primarily interested in map information. Certain additional information is therefore provided for a certain period of time, for example for a preset period or until the driver actively deactivates this function again 17th , 18th hidden so that the driver's attention is focused directly on the map display and the greatest possible information content can be taken from the map display. The screen display therefore goes from that in 2a shown state according to arrow 20 in the in 2 B shown state about. In the example shown, the is in the display mode 2 B the map is enlarged and the additional information 17th , 18th are hidden. This map mode can, for example, by a changed scale symbol 19 ' are displayed, which, for example, shows a concrete value for the respective magnification scale in manual mode.

After a preset time interval or if the user manually resets it using the rotary / pushbutton 14 switches the screen 12th from the display mode of the 2 B according to arrow 21st back to the display mode of the 2a with automatic adjustment of the magnification scale.
