发明名称 Vehicle navigation apparatus
摘要 A vehicle navigation apparatus searches a matching link within a tolerance range from a travel locus of a vehicle based on map data when the vehicle makes a turn, and the vehicle position is shifted to the matching link that is found in the search. After matching the vehicle position to the matching link, the vehicle position is returned to a pre-matching position when the vehicle is determined to have entered a facility for facilitating subsequent processing. By returning to the pre-matching position, the vehicle position can be processed and displayed accurately in the subsequent processing due to use of the vehicle position referring to the pre-matching position instead of a position after the matching control.
