Abstract

The invention relates to a method for operating a navigation system for calculating a route and route guidance from the current location to an enterable destination, wherein maneuver instructions are supplemented by outputting place names acoustically and / or optically during turnarounds (1), wherein a search along the Route that goes through or into a place (2), a next place (2) on the route is determined and used in the output.

Description

The The invention relates to a method for operating a navigation system according to the preamble of claim 1.

at generic navigation systems are so far the issue of street names and / or the use of information fixed to the card known.

The Issue of a street name is outside of localities, such as overland trips, often unhelpful, because there in reality one Orientation based on this street name difficult possible is. Such are street names for overland trips often not available or even difficult to see attached.

Farther would one sole indication of the numbering of the road in reality also only difficult to identify. Signs on the numbering of roads namely to be found Crossings are often very rare or difficult to recognize.

Farther are stationary information associated with the card, for example Signpost information, almost exclusively in the area of highways available, d. H. for example, at motorway junctions such as crosses and connection points. In the overland area, for example, on federal roads, Such information is not available and an orientation Such routes are difficult in reality.

Farther With currently known route guidance, only instructions are given at one Turning operation, d. H. It will be about 300 meters, then 100 meters and directly at the turning process an output, in particular an announcement, to the right or left turn, partly together with a Edition of the street name, output.

Farther is a unique route guidance through nakedness Indication of the turning direction (right or left) is not always possible because In some situations, there are several roads that are predetermined Turning direction (right or left) correspond. This is especially true in places where in a short sequence several bifurcated paths lead in the same direction but only one of the route guidance equivalent.

there It may happen during navigation, for example, by bad GPS signal or the known inaccuracy of GPS and the Map material misinterprets the announcement directly at the turn is given or at a wrong time and thus then in a wrong street is bent.

It is therefore the object of the present invention, a method to propose the operation of a navigation system, which the overcomes the above disadvantages and allows an improved orientation of the user.

These The object is achieved by the present invention according to the teaching of Main claim solved.

advantageous embodiments The invention are the subject of the dependent claims.

According to the invention Problem by the method for operating a navigation system to calculate a route and route guidance from the current location solved to an enterable goal, with maneuver hints be supplemented by that during turnarounds Place names are issued acoustically and / or visually, due to a query along the route that passes through or into a location Next Location determined on the route and used in the output.

In order to is during an active route guidance additionally or, alternatively to known outputs, also the place name relevant for this turn output.

This is particularly beneficial in situations where a street nameplate or a sign with the street number is hard to find or does not exist and therefore no Has recognition effect. Direction signs with place names are in reality far more common to be found and also much more clearly recognizable.

such Signs can be found in the traffic in less time, which the distraction from the traffic is kept shorter.

Consequently become the route guidance and greatly simplifies and improves the orientation of the user, and the user can briefly use the place-of-way information signs in reality itself orientate.

A Output in the form of an announcement could be included For example, as follows: "Please in 300 meters left turn off in the direction of Würzburg ", then" please in 200 meters turn left towards Würzburg "and finally" Now turn left towards Würzburg ".

The proposed solution to the problem reduces wrong turn-by-turn operations by making the turn-off situation quicker, more accurate Routing and providing a larger overview of the route.

The complement the maneuver instructions through the place names, for example, by replacing for this Note maneuvers provided information (eg signpost information) or by Add too for this maneuver note provided information.

The Type of issue is basically arbitrary, but finds particularly advantageous, for example, acoustically and / or visually. An additional Optical representation has the advantage that these are displayed permanently will be and can be looked up while making an audible announcement is not permanently audible.

One Next Location on the route is due to a query along the route, which leads through or into a place, determined and then used in the output. The query along the route can basically be configured as desired, and the route can be to next places be scanned.

Often run Routes through more than one place until reaching the destination. The Determination of a next one Location on the route can be the determination of the next town, but also the determination of the next but one, the third next Location etc.

at an advantageous embodiment of the procedure, the route is divided into segments, and the navigation system is the municipality area corresponding to a segment and / or the place name corresponding to a segment, wherein if a turn with corresponding maneuver note is detected, and if until a next turn along the segments a change of the municipality or the place is detected, the name of the new municipality area or the new place name used in the edition becomes.

A Route is divided into a variety of segments, where the segments for the route guidance provided roads represent. Thus, the segments are different communities, different places or, for example, in rural areas Territories, neither a municipality nor a place assignable. For example, by means of the stored in the map database Information or for example by means of an assignment table may be the name of the municipality or the name of the place corresponding to be determined for the segment.

Becomes a route guidance determined by a closed town, being closed Localities represent their own area category (so-called built-up area), For example, the name of the locality is relevant for the issue. These may also be districts with different from the church name Naming act, z. B. mesh instead of the municipality Seevetal. Leads against it a bypass around the closed town, so for example is the crossing the municipal boundaries for the detection of a given place name relevant, and the community name is used as the place name to be output. This is beneficial because the land area largely coverage through municipalities (with the exception of so-called community-free areas) is covered.

This Name can then be passed to the output.

These Detection and supply takes place in particular when a turn with corresponding maneuver instruction was detected and if until a next turn along the segments a change of the municipality or the location is detected.

The Detection of a turn with corresponding maneuver instruction indicates an imminent change of direction. Just before and during this Change of direction, ie the turning process, becomes the user of the navigation system in reality. The complement the output with a place name as a direction indicator is therefore advantageous.

Farther Along the segments until a next turn is the route after a change sampled in the municipality or town. This change Already at the next one Turning present, but also, especially in inner city turning operations, only in one of the following turns. After the change the municipality or the place has a new name. This name of the new municipality or the new place will be at the issue then used.

A change of the municipality or the place may be so pronounced that from a first municipality or place in a second municipality area or place is changed, but also that of any municipality or Place in a first municipality or place is changed. In the first Case is the name of the second municipality or place at the Issue used. In the second case, the name of the first municipality or location used in the output.

With in other words, if it is determined that a turn-off with corresponding maneuver instruction done, a review of the segments to a municipality or place through which the route passes. Is then at least one segment within another (new) municipality area or place has been found, is the corresponding name of the municipality or location used in the output.

at a further advantageous embodiment of the method is upon detection of several changes of the municipality or town until the next turn the name of the first new municipality area or the first new place name used in the output.

A Detection of several changes can for example, desirable be to the accuracy of route guidance and guidance to improve.

at a further advantageous embodiment of the method is upon detection of several changes of the municipality or the place until a next turn the name of the last new municipality area or the last new place name used in the output.

at a further advantageous embodiment of the method is upon detection of several changes of the municipality or the place until a next turn the name the most important new municipality area or the most important new place name used in the output, the importance being based on the corresponding number of inhabitants and / or the segments included and / or the corresponding degree of familiarity.

Note direction signs more important communities / places are often more attention-grabbing and made easier recognizable.

at a further advantageous embodiment of the method upon detection of several changes of the municipality or the place until a next turn several the name of the new municipality or several of the new place names used in the output.

at a further advantageous embodiment of the method the use of the location when issuing when driving through a locality depends on the size of the traversed Village.

If the announcement of the place name for the continuing Route, for example when navigating within towns, should not be necessary, the announcement of the place name can be prevented become. Often namely lie There are already alternative output supplements, such as street names, before and right in the center of big cities can be found for example frequently no directional signs.

in the In contrast, smaller towns often have none alternative edition supplements before, such as signpost information, and continue to find especially in smaller towns and direction signs for the incident and failing streets.

at a further advantageous embodiment of the method is upon detection of passing through a smaller town, the detection of the change of the municipality or town to that turn performed along the segments of the route, where a change of the municipality or the place takes place.

In order to can be ensured that in the presence of several turning operations within of a municipality or within a location not the issue of the location itself, because of the direct following turn not yet in another municipality or place. In one In such case, the segments of the next but one turn are considered etc..

at In a further advantageous embodiment, the size of the traversed Town on the basis of traversed traffic-calmed areas and / or by the presence of alternative output supplements and / or by population and / or by capital attribute and / or judged on the importance of the village passed through, the importance being based on the corresponding population and / or the segments involved and / or the corresponding degree of familiarity is judged.

at the alternative edition supplements can in particular, it is so-called signpost information act.

Also is a weighted mixed consideration of several of the above criteria possible.

in the The result can thus be assessed as to whether it is - in the sense described above - a smaller or larger town or big city is.

In a further advantageous embodiment of the method is the next place the route is a highway designation and used in the output.

Special Benefits arise because on signs, especially in the overland area, often also highway numbers as well as numbers of federal highways and highways can be found. The corresponding highway names can be for example about determine the map data, in particular in segments.

If between the present Turning process and the driveway on the highway no change can be detected in the municipality or the place, so can in this case, for example, only the highway number at the Edition can be used.

Lies between the present Turning and the highway entrance a municipality or a place so in this case, for example, the name of the community or the Place name used in combination with the highway number at issue become.

at a further advantageous embodiment of the method can also still behind the next one turn maneuver lying highways in combination with the previously mentioned community name or place name be issued.

Various embodiments The invention is illustrated in the drawings and will be described below exemplified.

It demonstrate:

1 the method in a turning process;

2 the method in a turn with several locations following;

3 a first form of presentation in the navigation with the method;

4 a more complex route guidance with different turns;

5 a route guidance with driveway on a highway;

6 different representations of the location information.

1 shows a turn 1 to the right towards a place 2 , where the route consists of different black and white marked segments. According to the state of the art, only the maneuver instruction "turn right" would take place during the turning operation.

Here, however, is also the place 2 into the turn 1 leads, with spent. The name of the place 2 is determined by a query along the route that passes through the location. These are the with the segments 3 corresponding names of the municipalities or places studied. Until the first segment 4 within the village 2 the segments correspond 3 with no municipality. Thus, a change of the municipality or place to the first segment 4 within the village 2 instead of. Such an investigation of the segments 3 will always take place when a turn 1 is detected with a corresponding maneuver reference, which it is necessary to supplement or replace.

The name of the place 2 , that is, the new place name, is then used in the output.

2 shows a route guidance from Augsburg to Munich over country road. On the way to Munich between Augsburg 11 and Friedberg 12 must turn right to Mehring 14 be bent and previously Neukissing 13 be crossed.

When turning 1 the segments of the route are examined for a change in the municipality or location until the next turn (not shown), and it is found that Neukissing 13 on the way to Mehring 14 is crossed.

at the output can now both places or just one are used, so for example the announcement "Please turn right in the direction of Neukissing ".

Furthermore, it is at the street 15 in the direction of Neukissing 13 around a highway, namely around a federal highway B2. In an optical representation ( 3 ) can the highway name 16 "B2" can be used along with the new place name in the output.

3 shows an optical representation of an output according to the method, wherein in the upper part of the representation, the optical output is carried out according to the method, here consisting of the highway designation 16 and the directional location 17 , In addition, here are the currently used road 18 and the road following the intersection in the future 19 listed.

However, street name information is often of little use on overland trips because street nameplates are in reality much less visible than directional signs which, and street nameplates in rural areas are partly not situated.

The driver can agree with the directional location 17 orientate much better in reality, because direction signs are large, immediate and easily recognizable.

Furthermore, in the presentation in addition to the directional location 17 "Neukissing" or "Mehring" will be displayed, since in this example it is assumed that between the current and the next turn process, church changes will be carried out in both locations and both places will be found on road direction information signs.

4 shows a more complex route from Oberpleichfeld to Altbessingen, the route through Opferbaum 21 first to Essleben 22 leads.

In Essleben finds the first turn 26 and immediately afterwards the second turn 27 in the direction of Mulhouse 23 instead of.

Because eating life 22 In this example, it has been recognized as a smaller town, for example by population, over the first turn 26 beyond the second turn 27 The changes in the municipality or town are examined until a change has been identified. The first segment within a new town lies in Mühlhausen 23 ,

Thus, the announcements in the turn-off operations 26 and 27 in eating life 22 are "Please turn left towards Mühlhausen" and at the second turn 27 "Please turn right in the direction of Mühlhausen".

Thus, it can be prevented that at the first turn 26 within eating life 22 the location Essleben 22 itself or no place name is used in the output.

In Mühlhausen 23 Turn right after Zeuzleben 24 , There could be the announcement "Please turn right in the direction Zeuzleben".

In Zeuzleben, turn left to Schraudenbach 25 Turned off, and the announcement could be "Please turn left towards Schraudenbach".

5 shows a routing from Jesteburg in the direction of Hamburg via the A7 motorway. Starting in Jesteburg 31 The route leads via Harmsdorf 32 and Ramelsloh 33 on the A7 motorway 34 ,

In Harmsdorf 32 could for the edition of the new place Ramelsloh 33 be used. To improve the remote orientation, but could also about the next place Ramelsloh 33 Be searched for the use of a highway on the route and then the A7 34 being found. In this case, for example, only the trunk road designation "A7" may be used in the output, or a combination of the new place name "Ramelsloh" and the future to be driven highway "A7" is used.

Thereby an orientation of the driver is significantly improved.

at an audible announcement could these are: "Please Turn right towards Ramelsloh / A7 motorway ".

These Output of additional information regarding the highway name is not limited to motorway names, but can on all Street number terms applied such as federal highway numbers or Country roads.

6 shows various representations of the optical output in the upper area in 3 , It will be the highway name 16 , here "A7", together with the directional location 17 , here "Ramelsloh", indicated.

The two display elements 16 and 17 can be underlaid with a country-specific marking color. Motorways are marked blue in Germany. Thus, the Fernstraßenbe designation 16 be highlighted in blue. Ramelsloh 33 is in the example accessible via a main road, which are marked yellow in Germany. Therefore, the trend-setting location 17 be highlighted in yellow here.

The representations 6b to 6e also include the highway name 16 and the trend-setting location 17 and moreover an arrow information for indicating the turning direction. It shows 6e a country-specific variant, the z. B. could find use in France.
