METHOD AND APPARATUS FOR DISPLAYING CURRENT VEHICLE POSITION |
摘要 |
Methods and apparatus are described for displaying information corresponding to a current vehicle position on a display of a vehicle navigation system. After the current vehicle position is determined by a separate process, the system determines the road on which the vehicle is currently located. The system then refers to a map database to construct a current road database corresponding to the current road. A current road segment corresponding to the current vehicle position is then determined. The system then refers to the current road database to determine a first geographical location based on the current vehicle road segment. The system then displays a text representation of the current vehicle position relative to the first geographical location.
