Abstract

The method involves determining a prognosticated driving route or an interest area for traffic information in a passive operating mode of a navigation system. The traffic information is outputted, where the traffic information concerns traffic route (W) located in an automatically and/or manually provided radius (R) or an area-section of an expansion around a vehicle (F) e.g. motor vehicle, position. A route guidance is started automatically as a function of the traffic information. The radius and/or the area shape is selected as a function of a represented map section of a display unit.

Description

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

From the DE 102 33 378 A1 is a forward-looking navigation system and a method known to be warned by their road users prematurely from disability on a route. If an entry of a travel route destination is omitted, a prognosis about a probable destination is made and an autonomous activation of the system is provided for an indication of a disability.

Furthermore, from the DE 102 53 135 A1 a method for preparing traffic information in a navigation system and a navigation system known. When a traffic obstruction occurs in the direction of travel, at least in a passive operating state of the navigation system, an indication of at least one road branch between the vehicle position and the beginning of the traffic obstruction is output.

In the DE 10 2004 017 091 A1 A method for operating a navigation system for a motor vehicle is disclosed, wherein for the user-friendly preparation of traffic information traffic messages depending on their relevance in at least two mutually delimited parts of an output list of the navigation system automatically sorted output. The sorting of the traffic reports in the subregions of the output list is adapted inter alia to a respective operating mode of the navigation system, in particular to the two operating modes "route guidance active" and "route guidance not active". This means that the traffic information can be output differently at least in a subarea corresponding to the respectively selected operating mode of the navigation system.

Furthermore, from the DE 10 2007 012 793 a navigation system with a functional unit that activates independently of an operator action at least one navigation function independently, as well as with a processor unit that stores and evaluates destinations. The processor unit is further intended to make a ring route planning. In addition, a navigation method for operator-independent activation of the navigation system is disclosed, wherein the ring route planning is performed.

Of the Invention is based on the object, an improved method to specify for the control of a navigation system, which in particular a provides comfortable and easy route guidance and one Operating effort for a user minimized.

The Object is according to the invention with a method solved, which specified in claim 1 features having.

advantageous Embodiments of the invention are the subject of the dependent claims.

at the method of the invention for control a navigation system for a vehicle is in one passive operating mode of the navigation system a predicted Driving route determined, depending on the predicted Route received traffic information filtered and output become. According to the invention those traffic information issued, which in an automatically and / or manually predefinable Radius around the vehicle position located traffic routes concern. In other words: as one or more predicted itineraries in an automatically and / or manually predefined radius around the Determined vehicle position located traffic routes, depending on the predicted route (s), such as those in the radius Traffic routes, received traffic information filtered and output become.

Thereby it is advantageous, even in a passive mode of operation, d. H. no route guidance is activated, possible, a clear presentation of traffic information represent by filtering relevant traffic information. Furthermore, warning functions may be subject to relevant malfunctions or disabilities are realized. Furthermore, can also be passive Operating mode depending on the traffic information automatically a route guidance can be started, which, for example Bypass recommendations and / or alternative route recommendations includes.

embodiments The invention will be described in more detail below with reference to drawings explained.

there demonstrate:

1 schematically a map representation and a section of this,

2 schematically output by means of a display unit map sections, and

3 schematically a vehicle and a ring route.

each other corresponding parts are in all figures with the same reference numerals Mistake.

1 represents a map view K and a section A of this, in which a vehicle F moves on a traffic route W.

In frequent trips of a user with the vehicle F in daily operation, such. B. to a workplace and back, the user or driver requires the actual guidance function of a 3 shown navigation system N rather not because he knows the way. On the other hand, traffic announcements for these standard routes are certainly of great interest.

The number of total offered, in 3 displayed traffic information I from a radio or the navigation system N without activated route guidance is usually quite large and often so confusing that it is difficult to identify relevant messages in concentration on the driving. Therefore, in such cases, the route guidance is still used to dynamic traffic information I, as example, messages from an RDS signal (RDS = Radio Data System) or via TMC (Traffic Message Channel) received messages to obtain only for the route. In this case, driving instructions of the navigation system N with respect to a route guidance can be perceived as disturbing. The operating effort to set up and start this required to obtain the filtered traffic information I route guidance is perceived as uncomfortable.

Therefore the method according to the invention provides that in a passive mode of operation of the navigation system N as one or more than one predicted route in an automatic and / or manually predefined radius R around the vehicle position Traffic routes W are determined, depending on of the predicted route or routes, such as those in the radius R located traffic routes W, received traffic information I filtered and output.

there In particular, those traffic information I are output, which are located in the predeterminable radius R to the vehicle position Traffic routes W concern. The size of the radius R can automatically and / or by the user of the vehicle F itself be given and thus always to its needs be adjusted. Thus, a qualified limitation the traffic information I possible without the user the navigation system N must activate the navigation system.

additionally can the predicted route depending on a stored statistic of start / target relationships become. Under the determination of the predicted route in Dependency of a stored statistics of start / target relationships is a determination of the route to be based on historical, d. H. based on past, journeys and driving habits. This is permanent in one embodiment of the invention a statistic of the trips made stored, in which the start / finish relationships, if necessary in dependence a week and / or time of day in a not shown Data base of the navigation system N stored and a renewed Start of the vehicle F are statistically evaluated.

This can be at the start in the 3 closer approximate starting point SP and possibly the start time are registered. In addition, when parking the vehicle F also in the 3 Target point ZP shown in more detail, the route traveled including the TMC identifications of the traversed with this route TMC track sections stored in the database. If the vehicle F is later started with a passive navigation system N, ie with the route guidance deactivated, the data stored in the database are retrieved and, if necessary, in the past, even restricted to a similar or equal daily or weekly time Several typical driven destinations and / or routes were used.

Becomes the vehicle F later with passive navigation system N, d. H. with deactivated route guidance, started retrieve the data stored in the database and compare it, whether in the past to a similar or equal daily or weekly one or more typical driven destinations and / or Driving routes were used.

At matches or similarities and accumulations of certain start / finish relationships in the background with deactivated route guidance one or calculates several predicted routes to the destination are stored histories of the routes from the database taken. From all received traffic information 1 will be the filtered and output to the user who predicted the Driving routes concern.

Consequently be the traffic information I in an advantageous manner to the predicted routes or on existing in these TMC sections limited, so the amount of traffic information I is significantly reduced.

In a profitable development of the invention, the statistics of the start / finish relationships is only stored if a current starting point SP of a stored as a favorite in the navigation system N starting point SP and / or destination point ZP equivalent.

This Approach is based on the assumption that the starting points SP and target points ZP of frequently traveled routes typically as personal Favorites stored under navigation destinations by a user become. Statistics of the start / finish relationships are preferred recorded only when the vehicle F directly to or at least near a starting point stored as a favorite SP and / or target point ZP starts. The recording becomes independent executed, whether with active or passive route guidance is driven.

Farther Preferably, the recorded statistics will only become final stored when the drive of the vehicle F on or at least in near a starting point SP deposited as a favorite and / or Target point ZP is terminated. This is advantageous possible, a data amount to be stored as possible is low and thus a required storage volume and a Processing costs are reduced.

There the statistics near busy roads W on frequent traveled routes containing the traversed TMC sections, it is possible in an advantageous manner, even then the route output traffic information 1 when the driver to a lesser extent from the route, for example due to a use of abbreviations or so-called secret paths, deviates, since the TMC sections not only individual traffic routes W but a group of different traffic routes W between two TMC points includes.

additionally It is possible that statistics for routes, which were not used for longer periods automatically and / or manually deleted by the driver become.

There when storing statistics, as already described, too Daily or weekly times are recorded and deposited, it is in advantageously possible already at a start of the Vehicle F a selection of eligible routes to limit and thus also the amount of traffic information to be output I reduce.

Alternatively, it is also possible for the user to specify a direction of travel of the vehicle F or to determine this automatically, so that the traffic information I output is limited to the traffic routes W or sections thereof, which can also be found in FIG 1 shown section A of the map display K in the direction of travel in front of the vehicle F are.

To The navigation system determines the automatic detection of the direction of travel N based on the current vehicle position possible or predicted routes or possible TMC sections to be traveled through, which have no defined destination or no defined Destination, but within a certain distance, d. H. especially within the radius R, lie. The routes can thereby also lead in different directions and / or within a certain distance on TMC sections.

When Driving direction may be a preferred direction from the start be derived traveled distance, so that z. B. in a movement of the vehicle F in the north in the first five minutes of driving, leading south Routes and / or TMC sections have no or at least less consideration Find.

In 2 are two map sections KA1, KA2 shown, the size of which is limited by a display unit of the navigation system N, not shown. According to one embodiment of the invention, the radius R is selected as a function of the displayed map section KA1, KA2 of the display unit, so that only those traffic information I are output that concern traffic routes W, which are in the map sections KA1 or KA2.

3 shows a ring route RR for the vehicle F with the navigation system N. The vehicle F or its driver and / or user starts at a starting point SP a ride and reaches a destination S1 point ZP or a waypoint. From this destination point ZP, the driver in turn travels back to the starting point SP over a distance S2, whereby the distances S1 and S2 can be identical, extending only in opposite directions. By means of this ring route RR, the already described daily route of the driver or user to his workplace or similar daily journeys can be depicted.

The Planning the ring route RR by means of the navigation system N can be such take place that the navigation system N passively determines the target point ZP. Does the vehicle F stays shorter than a set one now? Period of time defining a location as starting point SP at the destination point ZP or the milestone, is now of the Navigationssys system N passive of Starting point SP selected as target point ZP. Thus, a Total distance covered, which forms the ring route RR.

As a result, in addition to the increase in comfort due to the unnecessary destination input and route guidance, it is furthermore possible for only those traffic information items I to be output which are on roads W of the ring route RR or are located on this TMC sections, so that a clear presentation for the driver of the vehicle F is achieved.

Independently of whether the vehicle F on a ring route RR or a other predicted driving route may be dependent on the traffic information I automatically a route guidance to be started. This means that, especially in the event of traffic jams, Road closures or similar events the predicted route alternative routes are calculated and the driver by means of the route guidance bypass recommendations and / or alternative route recommendations.

Farther In addition to a simple acoustic or optical Issue of traffic information 1 also warnings, z. B. at Existence of wrong-way drivers or similar hazards, generated and be issued so that it by means of the invention Method and configurations of this is possible, the To assist the driver of the vehicle F in his driving activity, increase its comfort and increase traffic safety.
