Abstract
A vehicle position calculation apparatus and method are provided to correct a vehicle position to be located on a map route. The vehicle position calculation apparatus has a vehicle position measuring section measuring a vehicle position, a road data supply section supplying road geometrical data including a line segment and a closed region correlated with a road on a map, and a vehicle position correcting section correcting the vehicle position on the map by using the road geometrical data. The position correcting section locates the vehicle position by itself on the map as a corrected vehicle position, in response to a relatively positional relation between the vehicle position and the road geometrical data. In such a correction, the vehicle position correcting section can correct the vehicle position to be in alignment with a point on corresponding one of position correction shapes, or it can correct the vehicle position onto a traveling link generated in response to the road geometrical data.
