Abstract

In order to create a method for making available driving lane recommendations for each driving direction relating to at least one curb and interlinked with one another, as well as a system related thereto, which improve the quality of the driving instructions provided by a navigation device via optimized processing of the driving lanes on roads, in particular at intersections, it is recommended that (a) a curb (10, 11, 12; 10′, 12′, 15′) be assigned at least one lane list (20) whose elements (20.a.1.1, 20.a.1.2, 20.a.2) contain lane information on the totality of the driving lanes assigned to the curb (10, 11, 12; 10′, 12′, 15′); (b) each of the driving lanes be assigned at least one lane data list (30; 40) whose elements (30.b.1, 30.b.2; 40.b.1, 40.b.2) each contain lane data information on the particular driving lane; and (c) each follow-on driving lane succeeding the driving lane be assigned at least one follow-on lane list (50; 60; 70) whose elements (50.c.1, 50.c.2, 50.c.3, 50.c.4; 60.c.1, 60.c.2, 60.c.3, 60.c.4; 70.c.1, 70.c.2, 70.c.3, 70.c.4) each contain follow-on lane information, interlinked with the lane data information of the preceding driving lane, on the particular follow-on driving lane.

Claims

1. A method for use in a navigation device of making available a driving lane recommendation for each driving direction relating to at least one of a curb segment and a road segment and interlinked with one another, comprising:

assigning one of the curb segment and the road segment at least one lane list including elements containing lane information on a totality of driving lanes assigned to the one of the curb segment and the road segment;

assigning each of the driving lanes at least one lane data list including elements each containing lane data information on a particular one of the driving lane; and

assigning each follow-on driving lane succeeding the driving lane at least one follow-on lane list containing elements each including follow-on lane information, interlinked with the lane data information of a preceding driving lane, on the follow-on driving lane.

2. The method as recited in claim 1, wherein:

the elements of the lane list contain lane information on the driving lanes at the a beginning of the one of the curb segment and the road segment, on the driving lanes at an end of a cell unit, and on one of a length of the driving lanes and on a proportion of the length of the driving lanes of the one of the curb segment and the road segment.

3. The method as recited in claim 1, wherein:

a sequence of the elements of the at least one lane list corresponds to an actual sequence of the driving lanes.

4. The method as recited in claim 1, wherein:

the elements of the at least one lane data list include lane data information on each of the driving lanes on a direction of the driving lane and on at least one follow-on driving lane succeeding the driving lane.

5. The method as recited in claim 1, wherein:

the elements of the at least one lane data list include additional lane data information regarding one of a special use of the driving lanes and another restriction of the driving lane.

6. The method as recited in claim 1, wherein:

the elements of the at least one follow-on lane list each include follow-on lane information for each of the follow-on driving lanes on the follow-on driving lanes at the beginning of the assigned curb, on the follow-on driving lanes at the end of the assigned curb, on at least one of a direction and a position of the assigned curb, and on the number of the follow-on driving lane.

7. The method as recited in claim 1, wherein:

at least one of at least one driving lane and at least one follow-on driving lane of the one of the curb segment and the road segment is appended as at least one annotation.

8. A system for use in a navigation device of making available a driving lane recommendation for each driving direction relating to at least one of a curb segment and a road segment and interlinked with one another, comprising:

an arrangement for assigning one of the curb segment and the road segment at least one lane list including elements containing lane information on a totality of driving lanes assigned to the one of the curb segment and the road segment;

an arrangement for assigning each of the driving lanes at least one lane data list including elements each containing lane data information on a particular one of the driving lane; and

an arrangement for assigning each follow-on driving lane succeeding the driving lane at least one follow-on lane list containing elements each including follow-on lane information, interlinked with the lane data information of a preceding driving lane, on the follow-on driving lane.

9. The system as recited in claim 8, wherein:

at least one of at least one driving lane and at least one follow-on driving lane of the one of the curb segment and the road segment is appended as at least one annotation.
