20130080046 | APPARATUS AND METHOD FOR GUIDING DRIVING ROUTE TO DESTINATION - Disclosed are an apparatus and a method for guiding a driving route to a destination that accept a user's needs for a driving route as much as possible and promptly reflect traffic information in real time to guide a driver to arrive at his or her destination by using an optimal route. | 2013-03-28 |
20130080047 | VEHICULAR DRIVING ASSISTANCE APPARATUS - A present position candidate in a reverse run state of a vehicle and a present position candidate in a normal run state of the vehicle are clarified to be coexisting. When a collision buffer object peculiar to a branch point of a highway is detected by an image recognition from a vehicle front image captured by a front camera of the vehicle, the vehicle is determined to be in the reverse run state, thereby enabling a more accurate determination of the reverse run in the highway. | 2013-03-28 |
20130080048 | METHOD OF CALCULATING ACCURACY OF MEASURING LOCATION, AND METHOD AND APPARATUS FOR MEASURING LOCATION OF TERMINAL USING ACCURACY OF MEASURING LOCATION - A method of calculating an accuracy of measuring a location, and a method and apparatus to measure a location of a terminal using the accuracy of measuring the location, are provided. The method of calculating the accuracy of measuring the location of the terminal includes providing a map corresponding to a location measurement type that is used in the terminal. The method further includes reading, from the map, map information of a predetermined area including the location of the terminal. The method further includes calculating the accuracy of measuring the location with the location measurement type based on the map information. | 2013-03-28 |
