A location information obtaining apparatus of a vehicle, the location information obtaining apparatus comprising:
- a navigation device configured to obtain first global positioning system (GPS) information using at least one of a GPS navigation using a GPS signal and a dead reckoning (DR) navigation using speed information and direction information of the vehicle;
- a map matching feedback module configured to feedback second GPS information generated by map matching between the first GPS information and map data to the navigation device;
- and
- an application device configured to determine a current location of the vehicle based on the first GPS information received from the navigation device,
- wherein an activation of the map matching feedback module is controlled according to a location in a GPS shaded section of the vehicle or a driving distance of the vehicle in the GPS shaded section, and
- wherein the navigation device is further configured to generate third GPS information using the first GPS information and the second GPS information when the map matching feedback module is activated, and transmit one of the first GPS information and the third GPS information to the application device according to whether the map matching feedback module is activated.
A location information obtaining method of a vehicle, the location information obtaining method comprising:
- obtaining first global positioning system (GPS) information using at least one of a GPS navigation using a GPS signal and a dead reckoning (DR) navigation using speed information and direction information of the vehicle;
- controlling an activation of a map matching feedback module that generates second GPS information by map matching of the first GPS information and map data according to a location in a GPS shaded section of the vehicle or a driving distance of the vehicle in the GPS shaded section;
- when the map matching feedback module is activated, generating third GPS information using the first GPS information and the second GPS information;
- and
- determining a current location of the vehicle by use of one of the first GPS information and the third GPS information according to whether the map matching feedback module is activated.
