When a vehicle runs in a region other than existing roads stored as ready-made map data, learned road data (GL1) is generated based on a traveling locus. Further, an existing road connected with the learned road is defined as a base link (L1, L2). The base link is copied and divided, to generate auxiliary link data (GN1, GN2, SL1-SL4, SN1-SN8) to define a connection status between the learned road and the existing road in an auxiliary way. The learned road data and the auxiliary link data are recorded in association with each other. The auxiliary link data is used in navigation-related processing as a substitute for road data related to the existing road connected with the learned road. With this configuration, the existing road and the learned road are logically connected, to supplement consistency in a map containing the learned road without partially changing the ready-made map data. |
