Abstract

A device, computer program product and method for providing path information and a device using the method are disclosed. A method for providing path information comprises receiving broadcast signals comprising traffic information and cost information, extracting and storing traffic information and cost information from received broadcast signals, requesting information about navigation path after receiving a first position and a second position, and searching for paths leading to the second position from the first position and calculating cost required to reach the second position from the first position based on traffic information and cost information of each searched path and displaying the cost.

Claims

1. A method, comprising:

receiving broadcast signals comprising traffic information and cost information;

extracting and storing the traffic information and cost information from the received broadcast signals;

requesting information about possible navigation paths between a first position and a second position;

identifying at least one path leading to the second position from the first position;

calculating a cost associated with each path of the at least one path based on corresponding traffic information and cost information; and

displaying at least one calculated cost.

2. The method of claim 1, wherein the first position is a current position or a start position, and the second position is a destination or a way position.

3. The method of claim 1 further comprising:

calculating a distance and time required to reach the second position from the first position for each path of the at least one path based on corresponding traffic information; and

displaying at least one calculated distance and time.

4. The method of claim 1, further comprising:

receiving vehicle information; and

determining gas mileage information corresponding to the vehicle information.

5. The method of claim 4, further comprising:

storing the vehicle information and the gas mileage information, wherein

the vehicle information includes engine displacement information and vehicle year information, and

the step of determining the gas mileage information corresponding to the vehicle information includes referring to a lookup table pre-stored in memory.

6. The method of claim 4, farther comprising:

calculating a distance and time required to reach the second position from the first position for each path of the at least one path based on corresponding traffic information,

wherein

the cost information comprises fuel price information, and

the step of calculating a cost associated with each path includes;

calculating an estimated amount of fuel to be consumed based on the calculated distance, and

calculating a corresponding fuel cost based on the fuel price information and the estimated amount of fuel.

7. The method of claim 6, wherein

the cost information further comprises toll information of each path;

and

the step of calculating a cost associated with each path includes adding the toll information to the calculated fuel cost.

8. A device, comprising:

a display unit;

a broadcast signal receiver configured to receive broadcast signals comprising traffic information and cost information;

an information extraction unit configured to extract the traffic information and the cost information from the received broadcast signals;

an input unit configured to receive a first position and a second position and to receive a request for information about a navigation path; and

a controller configured to

identify at least one path leading to the second position from the first position,

calculate a cost associated with each path of the at least one path based on corresponding traffic information and cost information, and

display at least one calculated cost.

9. The device of claim 8, wherein

the first position is a current position or a start position, and

the second position is a destination or a way position.

10. The device of claim 8, wherein the controller is configured to

calculate a distance and time required to reach the second position from the first position for each path of the at least one path based on corresponding traffic information, and

display at least one calculated distance and time.

11. The device of claim 8, further comprising:

a memory configured to store vehicle information, wherein

the controller is configured to determine gas mileage information corresponding to vehicle information in the memory.

12. The device of claim 11, wherein the vehicle information comprises engine displacement information and vehicle year information.

13. The device of claim 11, wherein

the controller is configured to calculate a distance and time required to reach the second position from the first position for each path of the at least one path based on corresponding traffic information,

the cost information comprises fuel price information, and

the controller is configured to

calculate an estimated amount of fuel to be consumed based on the calculated distance, and

calculate a corresponding fuel cost based on the fuel price information and the estimated amount of fuel.

14. The device of claim 13, wherein

the cost information further comprises toll information of each path, and

the controller is configured to calculate the cost associated with each path by adding the toll information to the calculated fuel cost.
