发明名称 Car Navigation System
摘要 If a route has not yet been set in a car navigation apparatus, and when a vehicle approaches a specific crossing or a charging station located ahead of a current-driving road, or when remaining charge of a battery becomes less, the navigation apparatus retrieves and displays information about charging stations of the respective branching directions. When the vehicle approaches a specific crossing, the navigation apparatus guides information for indicating whether or not a charging station is present, a distance, and whether or not the vehicle can reach the charging station with respect to each of directions branched from the specific crossing. Also, when a charging station is located ahead of the road, the navigation apparatus retrieves charging stations of the respective branching destinations at a specific crossing located in front of the road, and judges whether or not the vehicle can be driven up to the respective retrieved charging stations.
