Abstract
A road shape predicting method includes the steps of: selecting three positions of positions of a plurality of nodes constituting road map data and an own vehicle position on a road; and predicting the road shape on the basis of a crossing angle formed by a link connecting a first position and a second position of the selected three positions and another link connecting the second and a third position thereof, and a link length between the second and the third positions. In case that the link length between the second and the third positions is not larger than a reference link length set in accordance with the crossing angle, the third position is excluded, and the position of a node further forward is adopted in place of the third position, to thereby predict the road shape.
