Abstract
A link that is closest to a departure place of one's vehicle is detected by a route searching. When a U-turn route link to come back from the closest link by passing from the closest link through the U-turn route again to the closest link is detected, a U-turn guide is made, based on a signal of this detection, to the effect that a return is made to the present position after a U-turn.
Claims6
A guide indication method for an onboard navigator in which a route guide to a destination along a route set in advance is indicated on a display, comprising:
- detecting, through a route searching, a closest link, on which a vehicle is traveling, that diverges from a node located on the route set in advance;
- determining whether the vehicle travels along the closest link in both directions of the closest link to return to the node;
- and
- performing a U-turn guide to indicate that the vehicle will return to the node by performing a U-turn on the closest link, when the determining step determines that the vehicle must travel along the closest link in both directions to return to the node.
