First Claim
Patent Images
1. A method for notifying of speed limit information for each block of a navigation system, the method comprising:
- maintaining a database which stores a start point and an end point of a speed limited block, and a speed limit for each block;
sensing whether a speed limited block exists in a front area while driving on a predetermined route; and
providing an speeding alert notification within the determined speed limited block when the speed limited block is sensed.

10. A navigation system comprising:
-
a database storing a start point and an end point of a speed limited block, and a speed limit for each block, the speed limited block being defined with a speed limit covering an entire nation; and a control unit providing a speeding alert notification, when a speed limited block is sensed while driving a predetermined route, while driving on a speed limited block, wherein the control unit calculates an estimated passage time required for passing through the speed limited block based on a start point and an end point corresponding to the speed limited block and the speed limit, and provides notification about the speed limit with the calculated estimated passage time.
