Abstract

In a method and systems for selecting traffic information services that are receivable by at least one mobile receiver and are relevant for a route previously determined by a navigational device linked to at least one receiver, service information, which identifies the services having traffic messages relevant for the route, is read out from a stored list for the determined route. In the case of a plurality of services, a table is created that includes the read-out service information, which is sorted according to a valuation and is able to be modified as the route is followed. A receiver is set, in each case, to the highest-rated service.

Claims

1. A method for selecting a plurality of traffic information services that are receivable by at least one mobile receiver and are relevant for a route previously determined by a navigational device linked to the at least one mobile receiver, comprising the steps of:

for the determined route, reading out service information from a stored list, the service information identifying those of the plurality of traffic information services having traffic messages relevant for the determined route;

in the case of the plurality of traffic information services, creating a table containing the read-out service information, the table being sorted according to a valuation and capable of being changed as the determined route is followed; and

setting the at least one mobile receiver, in each case, to a highest-rated one of the plurality of traffic information services.

2. A method for selecting a plurality of traffic information services that are receivable by at least one mobile receiver and are relevant for a route previously determined by a navigational device linked to the at least one mobile receiver, comprising the steps of:

for the determined route, reading out service information from a stored list, the service information identifying those of the plurality of traffic information services having traffic messages relevant for the determined route;

in the case of the plurality of traffic information services, creating a table containing the read-out service information, the table being sorted according to a valuation and capable of being changed as the determined route is followed; and

setting the at least one mobile receiver, in each case, to a highest-rated one of the plurality of traffic information services

fetching out a plurality of program identification codes for the determined route from the stored list, the program identification codes identifying transmitters having traffic information relevant for the determined route;

in the case of the plurality of fetched-out program identification codes, creating a table that includes the plurality of fetched-out program identification codes, the table including the plurality of fetched-out program identification codes being sorted according to the valuation and capable of being changed as the determined route is followed; and

setting the at least one mobile radio receiver, in each case, to a highest-rated and receivable one of the transmitters, wherein;

the at least one mobile receiver includes a radio receiver for receiving the transmitters having the traffic messages.

3. The method according to claim 2, wherein:

the stored list for the program identification codes includes information pertaining to a reception area covered by a message content and corresponding to a message area, known frequencies, and another message selection carried out by at least one of the transmitters.

4. The method according to claim 2, further comprising the step of:

determining and updating a table of the transmitters to be set by comparing positions on the determined route to regional information in the stored list.

5. The method according to claim 4, further comprising the step of:

sorting entries of the table of the transmitters to be set such that those of the transmitters having the most suitable message content are given highest priority.

6. The method according to claim 5, further comprising the step of:

transferring the table of the transmitters to be set to a control device of the at least one mobile receiver, wherein;

the table of the transmitters to be set is a basis for a transmitter search, and

the transmitter given the highest priority is searched first.

7. The method according to claim 6, wherein:

in the sorting step, a particular class of roads to be traveled is in relation to another message selection of at least one of the transmitters that identifies road classes for which the at least one of the transmitters broadcasts the traffic messages.

8. The method according to claim 2, wherein:

specified in a list for geographical regions into which a digital road map is partitioned for the navigational device are corresponding ones of the plurality of program identification codes, the method further comprising the steps of;

fetching out the plurality of program identification codes on a region-by-region basis; and

sorting the plurality of program identification codes as the determined route is followed.

9. The method according to claim 8, wherein:

in the sorting step, a particular class of roads to be traveled is in relation to another message selection of at least one of the transmitters that designates a size of a region for which the at least one of the transmitters broadcasts the traffic messages, and

with respect to different road classes within the region, those road classes that are most prevalent within the region are used for the sorting step.

10. A system for selecting a plurality of traffic information services that are receivable by at least one mobile receiver and are relevant for a route previously determined by a navigational device linked to the at least one mobile receiver, comprising:

an arrangement for, with respect to the determined route, reading out service information from a stored list, the service information identifying those of the plurality of traffic information services having traffic messages relevant for the determined route;

an arrangement for, in the case of the plurality of traffic information services, creating a table containing the read-out service information, the table being sorted according to a valuation and capable of being changed as the determined route is followed; and

an arrangement for setting the at least one mobile receiver, in each case, to a highest-rated one of the plurality of traffic information services, wherein;

the stored list and a digital road map are stored on a data carrier.

11. The system according to claim 10, wherein:

the data carrier includes an optically scannable disc.

12. A system for selecting a plurality of traffic information services that are receivable by at least one mobile receiver and are relevant for a route previously determined by a navigational device linked to the at least one mobile receiver, comprising:

an arrangement for, with respect to the determined route, reading out service information from a stored list, the service information identifying those of the plurality of traffic information services having traffic messages relevant for the determined route;

an arrangement for, in the case of the plurality of traffic information services, creating a table containing the read-out service information, the table being sorted according to a valuation and capable of being changed as the determined route is followed; and

an arrangement for setting the at least one mobile receiver, in each case, to a highest-rated one of the plurality of traffic information services, wherein;

the at least one mobile receiver includes two receiving sections that are capable of being set independently of one another.
