Vehicle-position-recognition apparatus and vehicle-position-recognition program

摘要

A history-information-generation unit (15) generating travel-history information indicating a route where a vehicle travels at a link-branch point based on a link determined by a link-determination unit (13) determining a link where the vehicle travels based on vehicle-position information and first and second road information items is provided. An image-recognition unit (16) recognizing the image of a recognition target on which data is included in image information about the vehicle's surroundings is provided. The travel-history information is stored in a learning database (DB2) in association with recognition information showing the recognition result of the recognition target. A learning unit (18) generates learning-priority information indicating the priority of each link based on the travel-history information and the recognition information for the link-determination unit (13) selecting the link where the vehicle travels from among links branched out at the branch point.
