1. A method of detecting a speed detection of a vehicle using a geographic database of a navigation system, the method comprising:
- obtaining a current position of the vehicle;
obtaining at least one predefined characteristic relating to the current position of the vehicle from the geographic database, the at least one predefined characteristic being a curvature of a road, a geometric shape of a road, a gradient of a road, or a slope of a road; and
automatically setting a sensitivity level to detect a speed detection of the vehicle based, at least in part, on the at least one predefined characteristic obtained from the geographic database, wherein automatically setting the sensitivity level includes automatically adjusting a current sensitivity level being used for detection to another sensitivity level used for detection and includes automatically changing a range of detectable area used to detect the speed detection of the vehicle based on, at least in part, the at least one predefined characteristic obtained from the geographic database.

Abstract
A technique of detecting a speed detection of a vehicle using a geographic database (200, 322, 326, 508, 510) of a navigation system (300, 502) has been provided, which obtains a current position of the vehicle (404) and at least one predefined characteristic (418) relating to the current position of the vehicle from the geographic database, sets (420(1)) a sensitivity level to detect a speed detection of the vehicle based, at least in part, on the at least one predefined characteristic.

15. A method of detecting a speed detection of a vehicle using a geographic database of a navigation system, the method comprising:
-
obtaining a current position of the vehicle; determining whether a speed trap data record associated with the current position of the vehicle is present in the geographic database; obtaining a road type characteristic from the speed trap data record when the speed trap data record associated with the current position of the vehicle is present in the geographic database; and automatically adjusting a sensitivity level to detect a speed detection of the vehicle based on the road type characteristic, wherein automatically adjusting the sensitivity level includes automatically increasing or decreasing a current sensitivity level being used for detection to another sensitivity level used for detection, based on the obtained road type characteristic, and includes automatically changing a range of detectable area used to detect the speed detection of the vehicle; and displaying a boundary of the range of the detectable area used to detect the speed detection of the vehicle. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)

23. A computer implemented method of detecting a speed detection of a vehicle using a geographic database of a navigation system, the computer implemented method comprising:
-
obtaining a current position of the vehicle; obtaining a road characteristic relating to the current position of the vehicle from the geographic database, the road characteristic comprising any one selected from a group of a road curvature, a terrain model of a road segment, a road gradient, a road slope model, a functional class of a road, and a geometric shape of a road; and automatically setting a sensitivity level to detect a speed detection of the vehicle based on the road characteristic obtained from the geographic database, wherein automatically setting the sensitivity level includes automatically adjusting a current sensitivity level being used for detection to another sensitivity level used for detection including automatically changing a range of detectable area used to detect the speed detection of the vehicle; and displaying a boundary of the range of the detectable area used to detect the speed detection of the vehicle. - View Dependent Claims (25)
