ABSTRACT:
A vehicle navigation apparatus comprises a control unit for computing an optimum travel route between a departure point and a destination of a vehicle to calculate similarity values each indicating degree of similarity between the pattern of the travel locus of the vehicle and the pattern of each of the travel roads included in a road map. The vehicle navigation apparatus further comprises a control unit for selecting, from the road map, candidate travel roads each having a road pattern having a similarity value exceeding a predetermined similarity level. The candidate travel roads includes a present travel road on which the vehicle is currently traveling. The control unit determines as to whether or not one of the candidate travel roads overlaps with the optimum travel route. A display or a loudspeaker informs to a vehicle driver that the vehicle comes to travel on the optimum travel route when it comes to be determined that one of the candidate travel roads overlaps with the optimum travel route, and informs to the vehicle driver that the vehicle comes to stray from the optimum travel route when it comes to be determined that no candidate travel road overlaps with the optimum travel route. The vehicle navigation apparatus thus constructed can flexibly determine whether the vehicle strays from the optimum travel route, thereby making it possible to prevent the vehicle driver from being perplexed by wrong information.
