Patent Images
1. A method of searching points of interest, or POIs, along a calculated route to be travelled, comprising:
- providing an initial search corridor of predetermined size, wherein the search corridor is indicative of a geographic area covering at least a portion of the route to be travelled;
performing a POI search within the provided search corridor; and
adjusting the corridor size for a subsequent POI search based on a number of POI hits found during the POI search in the currently provided search corridor,wherein the adjusting step and the performing the POI search step are iteratively repeated until the number of POI hits found within the iteratively adjusted corridor size meets an acceptance criterion, andwherein the adjusting step is stopped as soon as the acceptance criterion is met, whereas the performing the POI search step continues on a basis of the adjusted corridor size while traveling along the route.

14. A device for searching points of interests, or POIs, along a calculated route to be travelled, comprising:
-
a determining unit configured to provide a search corridor of predetermined size, wherein the search corridor is indicative of a geographic area covering at least a portion of the route to be travelled; a searching unit configured to perform a POI search within the provided search corridor; and an adjusting unit configured to adjust the corridor size for a subsequent POI search based on a number of POI hits found during the POI search in the currently provided search corridor, wherein the adjusting and the performing the POI search are iteratively repeated until the number of the POI hits found within the iteratively adjusted corridor size meets an acceptance criterion, and wherein the adjusting is stopped as soon as the acceptance criterion is met, whereas the performing the POI search continues on a basis of the adjusted corridor size while traveling along the route. - View Dependent Claims (15, 16)
