Navigation system for restrictively outputting warning and warning generating apparatus and method for restrictively outputting warning in a navigation system
First Claim
1. A warning generating apparatus for generating a warning in a navigation system, the apparatus comprising:
- a data receiving unit for receiving route guidance information data and outputting the route guidance information data;
a data analyzing unit for determining whether warning data has been included in the route guidance information data outputted from the data receiving unit or not;
a sensor for sensing a current travel speed of a movable body;
a restricted warning generating unit for receiving the route guidance information data from the data analyzing unit if the route guidance information data includes the warning data, for receiving the current travel speed from the sensor, and for determining whether the restricted warning generating unit will output a warning for the warning data based on warning generation conditions stored in advance according to a kind of the warning data; and
a warning/guidance output unit for outputting the warning corresponding to the warning data that is included in road guidance information data, when the restricted warning generating unit determines to output the warning. unit

Abstract
A navigation system utilizing a warning generating apparatus is disclosed. The warning generating apparatus includes a data receiving unit for receiving route guidance information data and current weather/time information from an external information center; a data analyzing unit for judging whether warning data has been included in the route guidance information data outputted from the data receiving unit; a sensor for sensing a current travel speed of a movable body; a restricted warning generating unit for receiving the route guidance information data having the warning data from the data analyzing unit if the route guidance information data is judged to include the warning data, and for determining whether it will output a warning for the warning data, based on warning generation conditions stored in advance according to a kind of the warning data; and a warning/guidance output unit for outputting warning information when the warning information has been transmitted after the warning has been determined to be outputted by the restricted warning generating unit.

9. A warning generating method for generating a warning of a navigation system, the method comprising the steps of:
-
receiving route guidance information data determining whether warning data has been included in the received route guidance information data;
checking a kind of the warning data when the warning data has been included in the route guidance information data;
determining if a warning corresponding to the warning data will be outputted, based on the checked kind of the warning data and based on warning generation conditions stored in advance according to the kind of the warning data; and
outputting the warning corresponding to the warning data when it is determined to output the warning. - View Dependent Claims (10, 11, 12, 13, 14)
