Definitions
- the invention relates to a method and arrangements for Selection of with at least one mobile receiver receivable traffic information services available for one of one associated with at least one receiver Navigation device previously determined route are relevant.
- TMC messages Traffic Message Channel
- DE 44 42 413 A1 discloses a method for adjustment a mobile radio receiver and a radio receiver become known, in which each of a Navigation device determined position for reading from Program identification codes is used from a list, so that a station is found, which determined for the Position sends relevant information.
- a Navigation device determined position for reading from Program identification codes is used from a list, so that a station is found, which determined for the Position sends relevant information.
- the transmission of traffic information services is also via other transmission media than RDS broadcasting, for example via digital radio (DAB) or via Mobile networks according to the GSM standard possible.
- DAB digital radio
- Object of the present invention is in a Route search with the help of a navigation device among the available transmission media and / or transmitters to make a choice which is an optimal supply with Traffic information over the entire route allows.
- This object is achieved in that for the determined route from a stored list Service information is read out which the services mark with relevant traffic information for the route, that creates a table in case of multiple services becomes, which the read out service information after contains a rating sorted and which at the Tracking the route is changeable, and that a receiver each set to the highest rated service becomes.
- the evaluation can be made according to characteristics which the Characterize services and together with the services itself received or from a memory at the receiver can be read out.
- the DAB tuner be set in the remaining areas of the RDS tuner and on selected routes or on special request the user's commercial services transmitted via GSM become. It is also possible for one area as well traffic messages received from multiple services save and use.
- a development of the present invention makes it possible in a route search using a navigation device the service receivable by a receiver such to select that over the entire route as possible Receipt of relevant traffic information is optimized.
- At least one receiver is a radio receiver to receive stations with traffic reports is that for the determined route from a stored list Program identification codes are read, which Sender with relevant for the determined route Traffic messages indicate that in the case of several read out program identification codes a table is created, which the read out Program identification codes sorted by rating contains and which in a pursuit of the route is changeable, and that the radio receiver on each the highest rated receivable station becomes.
- Navigation devices which the route also under Calculate consideration of the current traffic situation, - provided they have sufficient traffic information Measurements are fed - both at the start of a ride as also with an initially calculated route during the Ride the route to correct traffic reports. Furthermore, during a journey, a recalculation of the route be required if the vehicle (whether wanted or unintentionally) deviates from the calculated route.
- the inventive method allows independently of the Set the best stations available for this purpose.
- the stored list for the Program Identification Codes Information about the Reception area covered by the message contents Area (reporting area), the known frequencies and over an other message selection performed by the sender contains.
- the table of stations to be adjusted by Comparison of positions on the route with area information in the list is determined and updated.
- the entries in the table thus determined become such sorts that sender with the best matching Message contents are at the top of the list.
- the sorted table to a controller of the Radio receiver is handed over and there as a basis for a station search is used, with the one at the top standing transmitter is searched first.
- Broadcasters often have different preferences when it comes to Selection of the traffic reports broadcast by them. So For example, there are stations that are only local Send traffic reports or those that Broadcast traffic reports for a larger area. These characteristics of the transmitter can be with another Continuing to be used by that in sorting the respective class of roads to be traveled in relation to the other message selection of the transmitter is, which identifies the street classes for which the respective Sender sends traffic reports.
- a particularly favorable option for geographical Selection of the different transmitters or PI codes without the Relatively expensive storage of coordinates can according to an advantageous embodiment be effected in that in the list of geographical areas into which a digital road map for the navigation device is divided, the associated Program identification codes are listed and that at tracking the route by area Program identification codes are read out and sorted become.
- a secure match of the update status of the List and the digital road map is at one advantageous arrangement for carrying out the method according to the invention ensures that the List stored on the same disk as one digital road map, preferably on a visual scannable disc (CD-ROM).
- CD-ROM visual scannable disc
- the radio receiver shown in Fig. 1 has a Receiving part 2 with an antenna 1, whose output on the one hand via a low-frequency processor 4 and amplifiers 5, 6 with Speakers 7, 8 and on the other hand via an RDS decoder. 3 is connected to a microprocessor 13. This serves for Control of the entire radio receiver and is under designed to be different from the decoded at 3 RDS signal individual information, for example Program identification codes (PI codes) and digital ones Traffic messages to select and decode.
- PI codes Program identification codes
- Traffic messages to select and decode.
- the microprocessor 13 is further provided with a keyboard 14 and a display 15, with which various inputs (Tuning, volume, muting of received stations) made and required Information (operating status of the receiver, set Transmitter, traffic messages displayed as text) can be.
- the microprocessor 13 also has an output connected to a control input of the receiving section 2 is connected so that the receiving part 2 on at 14 per Hand or stored in the microprocessor 13 transmitter can be adjusted.
- the microprocessor 13 of the radio receiver is via a bidirectional data connection 10 with a Navigation device connected, also from a not shown microprocessor is controllable.
- the to Route search or to adapt the route search to the information required for each journey a mass memory 18, such as a CD-ROM, and a GPS locating device 17 taken.
- a mass memory 18 such as a CD-ROM, and a GPS locating device 17 taken.
- a digital Road map of which in Fig. 2 shows a section is
- TMC messages digitally coded traffic reports
- the list is by PI codes ordered and contains one PI code each Receiving area, a reporting area, frequencies on which Programs are sent with the respective PI code, and the sender's other message selection - for example, only local, regional and national Messages.
- the list shown in detail in Fig. 3a) shows Entries of the five stations Sa to Se with the PI codes PI1 to PI5.
- the reception ranges of the transmitters Sa to Se are shown in FIG. 2 identically represented with the transmitters.
- the file is particularly simple constructed that areas of the digital map (Fig. 2) in Areas - also called PI areas in the following - are divided and that for each of these areas the the relevant channel in the list. That's how it works from the list of Fig. 3a), for example, that the Sender Sa for the area C2 traffic reports and the Sender Sb Traffic reports for the areas C1, C2 and B2 radiates. This eliminates an assignment of Message areas of the individual stations to the geographical Coordinates.
- the navigation device 16 determines on the basis of own position, in which PI area the vehicle stops, and then can go directly to the appropriate Jump section of the PI code table, where then there is a or more PI codes, for example in Fig. 3a) for the range C2, the PI codes PI1 to PI4.
- FIG. 2 shows a section of a total of sixteen PI areas A1 to D4 of the digital road map.
- For one Driving from a place X to a place Y has made a Route search show that first of X an intra-local Road 21 to a motorway junction 22, then one Drive on the highway 23 to junction 24 and finally again a local road 25 used becomes.
- Another street 26, also from X to Y is not suggested to the driver as this leads winding route is longer and also more time claimed.
- circles or ellipses are the Reception areas of the transmitter Sa to Se indicated. Does that fall largest part of a PI area in the reception area, is this in the table of Fig. 3a) in the respective Station listed.
- the stations Sa and Se are local stations, while the stations Sb, Sc and Sd are supraregional receivable. At the start the receiver is in area C2. After the list should the stations Sa to Sd be receivable there. Because the first route 21 is not a motorway, becomes the local station Sa first highest prioritized. The remaining stations after evaluation of the receivability in the subsequent PI areas B2 and A2. Since the Transmitter Sd is receivable in all three PI ranges the transmitters in the sequence Sa shown in FIG. 3b), Sd, Sb, Sc to the microprocessor 13 of the radio receiver to hand over.
- Fig. 4 shows a flowchart of a program that in a Microprocessor of the navigation device for implementation the method according to the invention is provided. After one Start at 31 and enter X and Y at 32 takes place at 33 the route calculation with the result X, 22, 24, Y. Then the program waits for an input, whether a dynamic Route guidance is desired. If this is not the case, will the program ended at 35. Will be a dynamic Destination guidance desired, at 36 the determination of PI areas, in the present case C2, B2 and A2.
