Definitions
- the invention relates to a method and a navigation system to determine one of at least two sub-routes Overall route between a first and a second Location by means of a route calculation device, wherein the Partial routes consist of knots and edges and the overall route past an indirect intermediate destination.
- a route calculation device is any Device understood which for determining a route between a start and a destination can.
- This may be a navigation system in a motor vehicle, a stationary computer with appropriately installed route calculation software or access to the Internet or even a portable device, such as a cell phone or a PDA.
- the route can be calculated for motorists or pedestrians, for example become.
- the previously in the trade allow available software or devices for route calculation only the specification of directly approachable intermediate destinations, in the following direct intermediate goals called. For example, would like an operator from Frankfurt on the Highway to Düsseldorf and not as one of Route calculation unit proposed via the A3 direction Cologne / Bonn but drive over the A45 past victories, So he can currently select victories only as a direct stopover. This leads to the routing through the Downtown Siegen takes place. Alternatively, the Users try to go straight over the highway Intermediate destinations, such as certain motorway junctions the Influence routing. But this would have to him Already be known, which is a precognition of the Approximate route requires and thus contrary to the actual Purpose of a route calculation unit stands.
- DE-10036817-A1 proposes in this context a method in which, starting from a starting location, a route calculation in the direction of an indirect intermediate destination, called transit destination, is started and runs until the route has reached a so-called capture area around the transit destination. The route calculation is aborted at this point and, starting from the intermediate point thus found, a further route calculation is carried out in the direction of a next transit destination or in the direction of the final destination.
- the size of the capture area is either fixed or adapted to the length of the calculated route or to a required change in the road class, for example, from the highway to the highway.
- the route calculation can become problematic when a user selects a transit destination in an unusual location for the optimal route, ie the route determined without a transit destination. For example, the transit destination may be placed very close to the starting or final destination or quite close to the optimal route.
- the catching area around the transit destination determined by the above-mentioned criteria coincides with a high probability with the near surroundings of the starting and destination locations, the calculated route will not be different from the optimal route.
- the desire of the user to deviate from the optimal route is ultimately disregarded.
- German application 10218340.6 are a method and a navigation system for Determining a route for a motor vehicle, in which on a map an indirect waypoint, here Waypoint called, by means of a movable marker is selected.
- This waypoint defines a preferred one Routenkorridor, by the route calculation unit so between Start and destination is placed that waypoint in the route corridor is included.
- a Route calculated between start and destination, with the range within the route corridor is preferred.
- Such Favor is achieved, for example, by the fact that in the digital road map the individual sections associated resistance values within the corridor be lowered.
- the from the route calculation unit suggested route corridor the user can Desire to change the course of the resulting route continue to influence.
- the object of the present invention is therefore a method for determining a route via an indirect intermediate destination to specify which with little effort in one existing route calculation system can be implemented can.
- the method and a generic navigation system should also allow a simple operation.
- This node becomes a direct stopover placed in the place of indirect intermediate destination and the Section of the intermediate route between the starting point and the new one found direct interim destination is considered a first partial route Are defined.
- Starting from the direct intermediate destination can now, again with the standard algorithm, a second sub-route be calculated to the destination and this with the first Partial route to a total route.
- the overall route is the operator of the route calculation unit in known manner displayed on a graphical output unit, either in the form of the route on a map or as a sequence of navigation hints in visual or audio form.
- the inventive method has the advantage that large Parts of the existing route calculation system in their original Form can be used and only additional Software modules created and attached to the system, so to speak become.
- the already implemented method for the calculation a route between a start and a destination point involving a direct intermediate objective only modified insofar as that created additional functions need to be calculating different from Criteria dependent distance between indirect and to looking for a direct waypoint, to find the direct waypoint on the calculated intermediate route and to shorten the intermediate route at the node found.
- An intermediate target specified by the operator for conventional width must further only by adding a further attribute as indirect intermediate target become.
- Input options are used, such as entering per Keyboard, selecting from a list of places or the graphical input on a map via cursor and mouse click.
- the method according to the invention offers the possibility the well-known and already optimized operating options of route calculating facilities.
- the Marking the waypoint as an indirect waypoint does not require more than, for example, an extra Click.
- a navigation system which contains a computing unit, the designed for carrying out the method according to the invention is.
- This arithmetic unit is equipped with an input unit, such as For example, a keyboard, a mouse, a touch screen or a control unit with rotary and function switches for Input of an indirect waypoint connected.
- the arithmetic unit with an optical output unit connected, on which a map is displayed.
- Map are at least the start and finish, the indirect Intermediate target and the course of the overall route graphically represented.
- the operator gives his in a known manner Start and destination and selects an intermediate destination, which he only characterize as an indirect intermediate goal got to.
- a definition of further characteristics or attributes is not required and also an iterative approach to Definition of, for example, a route corridor is eliminated.
- the node of the intermediate route to be searched for from a set of selected potential intermediate destinations.
- This amount of potential intermediate points corresponds to the quantity of nodes of the intermediate route, which are within one of certain criteria dependent distance from indirect Intermediate destination.
- the distance, the amount of Potential direct intermediate goals, is in the generally greater than or at most the same size as the Distance, within the one to be subsequently searched Node of this set lies. Equally large distances result if the same applies to the calculation of both distances Criteria are used.
- this intermediate step of defining a set of potential intermediate points becomes the search algorithm to find the one node which is the indirect one Intermediate target to replace direct intermediate target, simplified. A large number of nodes of the intermediate route can do so already be excluded from the search from the outset, which reduces the computing time.
- the first described sequence of essential for the route Places namely starting place, indirect waypoint, direct Intermediate destination and destination serves as the basis for a further embodiment of the method according to the invention.
- this embodiment does not become the indirect intermediate destination only replaced by one but by two direct intermediate goals.
- two intermediate routes are calculated, the first one between the place of departure and the indirect intermediate destination and the second between the intermediate indirect destination and the destination.
- the node is determined which within a range determined by different criteria Distance from indirect intermediate destination.
- These two Nodes replace the intermediate indirect destination as direct intermediate goals.
- the two intermediate routes will be at this node shortened and between the direct intermediate goals becomes the still missing partial route calculated.
- the second direct stopover as a substitute node for the indirect can also come from one again Amount of potential direct intermediate destinations selected which are all within a certain distance from the indirect waypoint, thereby searching of the replacement node on the second intermediate route.
- the indirect intermediate destination be given as a place name, and the villages or towns can be an areal expansion in the form of a surrounding the place Circle or Rectangles are assigned.
- the distance-determining Criterion the street class of the nodes of the intermediate route considered. For smaller streets, such as passageways or Highways, resulting in smaller distance values and for Highways and federal highways. For longer overall routes, which are mainly on the larger roads, will thus ensuring that for passing the indirect Stopover no unnecessary class change to smaller ones Roads take place.
- the overall route should be rather short or maybe only on smaller roads anyway lead along, for example, the operator on a scenic beautiful route wants to go to the indirect Intermediate target also approached closer.
- Another criterion for determining the distance to the indirect intermediate destination are the geometric relationships of a triangle, which is spanned by the starting location, the indirect intermediate destination and the destination.
- the ratios of the side lengths of this triangle are of interest to each other, as these indicate whether and to what extent the indirect intermediate destination is closer to the start or the destination. If the operator has placed the indirect intermediate destination very close to one of these locations, normally the route would not be affected by this. For this reason, in such a case, the distance value is chosen to be quite small in order to actually redirect the route toward that intermediate destination. It is also interesting to consider the angle of the triangle.
- the indirect intermediate destination is far away from the optimal route between the start and destination.
- the distance for the replacement node to be searched can be relatively large in this case. It can be assumed that in a calculation of two individual routes between the starting point and the intermediate destination or the intermediate destination and the destination, the two routes in the vicinity of the indirect intermediate destination due to its acute-angled position meet and continue identically to the interim destination. However, since the operator does not want to go back and forth on one and the same road, a substitute node for the indirect waypoint has to be found at some distance.
- Another angle of interest is the angle with the vertex at the starting point. If this angle is rather small, the indirect intermediate destination is close to the optimal route between the start and destination.
- All the mentioned criteria can be arbitrary individually or also all combined with each other to the distance values even better to adapt to the wishes of the operator.
- a preferred Combination is that by the spatial Extension of the intermediate indirect objective Distance values are multiplied by a factor which depends on the road class of the nodes of the intermediate routes. The result of this multiplication can be further Multiplications are changed, with the other factors from the properties of the triangle described above be determined. In the optimal case, due to the combination This criteria calculates a route by the operator is accepted immediately. This saves him any attempts through changes in the specification of the indirect intermediate objective or by entering additional direct or indirect Interim goals to shape the route according to his ideas.
- the distance-determining To adapt criteria to the current geographical area.
- the navigation system according to the invention is in a development characterized in that the arithmetic unit for Execution of the route calculation method with the replacement indirect intermediate objective via two intermediate direct destinations is trained.
- the output unit points at this navigation system the same total route for a route calculation from the starting point via the indirect waypoint to the destination like for a calculation from the destination via the indirect intermediate destination to the starting point.
- Another special design of the navigation system provides that in addition a storage unit for storage of configuration files included in the navigation system is where the configuration files are to determine the distances serve the quantities of the potential direct Determine intermediate goals or define the nodes, which replace the indirect intermediate objectives.
- Fig. 1 is the outline of a map of Germany in the background to see.
- SO Prescribed operator of a route calculation device
- IZ indirect intermediate destination
- destination ZO destination ZO
- an intermediate route is calculated, in the case illustrated, only four major nodes between SO and IZ.
- a distance E1 which is also called a circle around IZ can be considered with the radius E1. It will be the one now from the four nodes of the intermediate route between SO and IZ selected, which is farthest from IZ, but still within the distance E1 lies.
- This knot will defined as direct intermediate destination DZ1 and the intermediate route is truncated at this node, so that the first partial route composed of the nodes SO, K1, K2, K3 and DZ1.
- DZ1 a second partial route to ZO is calculated afterwards, which contains the nodes K4 to K7.
- the dashed The total route drawn is made up of the two sub-routes and performs at a distance that a little bit smaller than E1, past the indirect intermediate destination IZ.
- Fig. 2 shows the procedure, if IZ not replaced by one but by two direct intermediate goals DZ becomes.
- a first intermediate route between SO and IZ there is the first node within E1 is located, selected and defined as DZ1 and the Intermediate route to DZ1 abbreviated to the first partial route.
- DZ1 the Intermediate route to DZ1 abbreviated to the first partial route.
- DZ2 the Intermediate route to DZ1 abbreviated to the first partial route.
- the second intermediate route is truncated to DZ2 so that it runs between DZ2 and ZO.
- DZ1 and DZ3 a third Partial route calculated and the dashed overall route composed of the three sub-routes.
- the chronological order The individual steps can be varied to a certain extent because, for example, the intermediate routes are both calculated simultaneously and DZ1 and DZ2 determined simultaneously can be.
- FIG. 3 illustrates how the distance for selecting a node of an intermediate route is determined.
- IZ is a rectangle, which indicates the areal extent of IZ. Based on geometric dimensions of this rectangle, such as a page length or diagonal, a first value is set as the distance value. In the case presented here, this is multiplied by five different factors, which leads to five differently sized dashed circles around IZ. Each of the five factors corresponds to a road class, with the highest road class, the highways, being linked to the largest factor, leading to the outermost circle.
- the search for the node replacing the indirect intermediate destination is started. For this, the largest of the five radii is defined as the so-called second distance value E2.
- This distance value E2 determines all nodes of the intermediate route between SO and IZ within the outer circle as the set of potential direct intermediate destinations that can replace IZ.
- the search can now be started and carried out in the direction IZ.
- the next node in the direction of IZ is queried for its associated road class and assigned to one of the five radii corresponding to the road class. If the considered node lies within the radius assigned to it, the direct intermediate destination is found.
- a node K1 is located between the outer radius E2 and the next smaller radius. This node has the second highest road class, ie the stretch of road on which it lies is a federal highway. It is therefore assigned the second largest radius as the distance value to be checked.
- the search must continue.
- the next node, also located on a main road, is then already within the radius assigned to it, whereby the direct intermediate destination DZ1 is found.
- the radius assigned to it is referred to as the first distance value E1.
- the first partial route TR1 is determined and, starting from DZ1, the second partial route TR2 is calculated.
- IZ is relatively close in FIG at SO. Is between SO and ZO a route possible via motorway chosen, the largest radius around IZ becomes relatively generous be. However, this could lead to the found direct stopover on the direct link between SO and ZO lies, so on the optimal route between SO and ZO. However, because the user intends to change the route, the radii around IZ should be rather small. This is achieved by changing the ratio of sides a to b is looked at. If this clearly does not equal one, so IZ is close to SO or ZO and the radii will be chosen small.
- FIG. 5 Another special case is shown in FIG. 5.
- IZ is far away from the optimal route between SO and ZO.
- a consideration of the angle ⁇ with the vertex in IZ makes this clear. Since this angle has only a small size, are larger radii around IZ to avoid unnecessary driving back and forth avoid on one and the same route near IZ.
- FIG. 7 actually shows this on an output unit a navigation system shown result a route calculation according to the invention in comparison to a previously possible with the same navigation system possible Route calculation via intermediate destinations.
- Starting point is SO Nuremberg
- indirect intermediate destination IZ is Regensburg and destination ZO is Munich.
- As in the one pulled out on the right enlarged image section of IZ can be seen performs the calculated according to the method of the invention Route at a considerable distance past Regensburg.
- One Shut down the highway is completely avoided.
- IZ treated as a direct intermediate objective and the proposed route to the city center from Regensburg.
- On the routes shown are single nodes highlighted as thicker points along the way.

Abstract
Description
In der DE-10036817-A1 wird die Größe des Fangbereiches entweder fest vorgegeben oder an die Länge der berechneten Route bzw. an einen erforderlichen Wechsel der Straßenklasse, beispielsweise von der Autobahn zur Landstraße, angepasst. Bei einem derartigen Vorgehen kann die Routenberechnung dann problematisch werden, wenn ein Benutzer einen Durchgangszielort in einer ungewöhnlichen Lage zur optimalen Route, also der ohne Durchgangszielort ermittelten Route, wählt. So kann der Durchgangszielort beispielsweise sehr nahe an den Start- oder Zielort oder ziemlich dicht neben die optimale Route gelegt werden. Da in einem solchen Fall der nach den genannten Kriterien festgelegte Fangbereich um den Durchgangszielort die nähere Umgebung von Start- und Zielort bzw. optimaler Route mit hoher Wahrscheinlichkeit mit überdeckt, wird sich die berechnete Route nicht von der optimalen Route unterscheiden. Der Wunsch des Benutzers, von der optimalen Route abzuweichen, bleibt im Endeffekt unberücksichtigt.
Ein weiterer Winkel von Interesse ist der Winkel mit dem Scheitelpunkt am Startpunkt. Ist dieser Winkel eher klein, so befindet sich das indirekte Zwischenziel nahe der optimalen Route zwischen Start- und Zielort. Auch in so einem Fall würde normalerweise die Streckenführung durch das Zwischenziel nicht beeinflusst werden. Um dies aber nach Wunsch des Bedieners doch zu erreichen, wird der Entfernungswert wieder ziemlich klein gewählt.
Die Betrachtung des Dreieckes zwischen Startort, Zwischenziel und Zielort bringt den Vorteil, dass gegenüber dem bekannten Verfahren auch eine ungewöhnlich gewählte Lage des indirekten Zwischenziels mitberücksichtigt wird und zu einer Veränderung der optimalen Route führt.

- Fig. 3
- eine Darstellung von Kriterien zur Festlegung von Entfernungen vom indirekten Zwischenziel;
- Fig. 4 bis 6
- Sonderformen von entfernungsbestimmenden Dreiecken.
Nachdem die Zwischenroute zwischen SO und IZ berechnet wurde, wird mit der Suche nach dem das indirekte Zwischenziel ersetzenden Knoten begonnen. Dafür wird der größte der fünf Radien als sogenannter zweiter Entfernungswert E2 festgelegt. Dieser Entfernungswert E2 bestimmt alle innerhalb des äußeren Kreises befindlichen Knoten der Zwischenroute zwischen SO und IZ als Menge der potentiellen direkten Zwischenziele, die IZ ersetzen können. An dem ersten außerhalb von E2 liegenden Knoten kann nun mit der Suche begonnen und in Richtung IZ durchgeführt werden. Dazu wird der jeweils nächste Knoten in Richtung IZ auf seine zugehörige Straßenklasse abgefragt und ihm entsprechend der Straßenklasse einer der fünf Radien zugeordnet. Liegt der betrachtete Knoten innerhalb des ihm zugeordneten Radius, so ist das direkte Zwischenziel gefunden. In Fig. 3 liegt ein Knoten K1 zwischen dem äußeren Radius E2 und dem nächstkleineren Radius. Dieser Knoten hat die zweithöchste Straßenklasse, d.h. der Straßenabschnitt, auf dem er liegt, ist eine Bundesstraße. Ihm wird also der zweitgrößte Radius als zu überprüfender Entfernungswert zugeordnet. Da K1 außerhalb des zweitgrößten Radius liegt, muss die Suche fortgesetzt werden. Der nächste, ebenfalls auf einer Bundesstraße befindliche Knoten liegt dann bereits innerhalb des ihm zugeordneten Radius, womit das direkte Zwischenziel DZ1 gefunden ist. Der ihm zugeordnete Radius wird als erster Entfernungswert E1 bezeichnet. Zwischen SO und DZ1 wird nun die erste Teilroute TR1 bestimmt und ausgehend von DZ1 die zweite Teilroute TR2 berechnet.
