Output control method of voice guidance signal in navigation system
First Claim
1. A method for controlling the output of a voice guidance signal in a navigation system, the method comprising:
- searching for a travel route from a starting location to a destination of a vehicle;
guiding the vehicle to travel along the searched travel route;
determining a current vehicle location when the vehicle is traveling;
searching for a target location to be guided that exists ahead of the traveling vehicle;
generating a voice guidance signal for the searched target location;
determining a priority according to a distance relationship between the current vehicle location and the searched target location and a specific characteristic of the searched target location;
assigning the priority to the generated voice guidance signal in advance; and
outputting the generated voice guidance signal in conflict with an output of a plurality of voice guidance signals when the generated voice guidance signal has a highest priority,wherein determining the priority comprises;
designating a voice guidance signal for guiding arrival at a destination with a first priority;
designating a last voice guidance signal issued just before the vehicle passes by a predetermined target location to be guided with a second priority when the predetermined target location to be guided is guided three times with voice guidance signals including initial, intermediate and last voice guidance signals;
designating a voice guidance signal for guiding a dangerous area with a third priority;
designating an initial or intermediate voice guidance signal for the predetermined target location to be guided with a fourth priority; and
designating a voice guidance signal for guidance of a joining point, an entrance to a comfort stop, straight driving, or a registration area with a fifth priority.

6. A method for controlling the output of a voice guidance signal in a navigation system, the method comprising:
-
searching for a travel route from a starting location to a destination of a vehicle; guiding the vehicle to travel along the searched travel route; determining a current vehicle location if the vehicle is traveling; searching a to-be-guided target location ahead of the traveling vehicle; generating a first plurality of voice guidance signals for the searched to-be-guided target location; placing a second plurality of previously-generated voice guidance signals on standby according to predetermined priorities; selecting a generated voice guidance signal among the first plurality of voice guidance signals and the second plurality of previously-generated voice guidance signals on standby; and outputting the selected voice guidance signal by a voice guidance signal output unit if the voice guidance signal output unit does not currently output a voice guidance signal, wherein determining the priority comprises; designating a voice guidance signal for guiding arrival at a destination with a first priority; designating a last voice guidance signal issued just before the vehicle passes by a predetermined target location to be guided with a second priority when the predetermined target location to be guided is guided three times with voice guidance signals including initial, intermediate and last voice guidance signals; designating a voice guidance signal for guiding a dangerous area with a third priority; designating an initial or intermediate voice guidance signal for the predetermined target location to be guided with a fourth priority; and designating a voice guidance signal for guidance of a joining point, an entrance to a comfort stop, straight driving, or a registration area with a fifth priority. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)

16. An apparatus for controlling the output of a voice guidance signal in a navigation system, the apparatus comprising:
-
a global positioning system (GPS) receiver configured to receive a navigation message; a sensor unit configured to detect travel conditions of a vehicle; a map data storage unit configured to store map data; a control unit configured to search for a travel route from a starting location to a destination of the vehicle using the stored map data; a display unit configured to display the searched travel route and a current vehicle location; and a voice guidance signal output unit configured to output a voice guidance signal, wherein the control unit guides the vehicle to travel along the searched travel route, wherein the control unit determines the current vehicle location when the vehicle is traveling by using the received navigation message and the detected travel conditions of the vehicle, wherein the control unit searches for a target location to be guided that exists ahead of the traveling vehicle, wherein the control unit generates a voice guidance signal for the searched target location, wherein the control unit determines a priority according to a distance relationship between the current vehicle location and the searched target location and a specific characteristic of the searched target location, wherein the control unit assigns the priority to the generated voice guidance signal in advance, wherein the control unit provides the generated voice guidance signal in conflict with an output of a plurality of voice guidance signals when the generated voice guidance signal has a highest priority, and wherein the control unit designates a voice guidance signal for guiding arrival at a destination with a first priority, designates a last voice guidance signal issued just before the vehicle passes by a predetermined target location to be guided with a second priority when the predetermined target location to be guided is guided three times with voice guidance signals including initial, intermediate and last voice guidance signals, designates a voice guidance signal for guiding a dangerous area with a third priority, designates an initial or intermediate voice guidance signal for the predetermined target location to be guided with a fourth priority, and designates a voice guidance signal for guidance of a joining point, an entrance to a comfort stop, straight driving, or a registration area with a fifth priority when the control unit determines the priority.
