Abstract:
A route guidance unit includes: a detection unit configured to detect a position of a host vehicle; a guide unit configured to provide guidance on a travel route when a distance from the position of the host vehicle detected by the detection unit to a branch point on the travel route reaches a predetermined distance; and an accuracy determination unit configured to determine a degree of accuracy of the position of the host vehicle, wherein, when the accuracy determination unit determines that the degree of accuracy of the position is a predetermined threshold or less, the guide unit provides the guidance on the travel route at a point before the distance from the position of the host vehicle to the branch point reaches the predetermined distance.

Claim (Index 1):
A route guidance device used for a vehicle which provides a travel route to a predetermined destination or an autonomous vehicle which is autonomously driven along the travel route, the route guidance device comprising:\n an estimation unit configured to estimate a position of a host vehicle and a travel lane; a guide unit configured to lead the host vehicle to change lanes toward the travel route when a distance from the position of the host vehicle estimated by the estimation unit to a branch point on the travel route reaches a predetermined distance; and a determination unit configured to determine accuracy of the travel lane of the host vehicle estimated by the estimation unit, wherein, when the determination unit determines that the accuracy of the travel lane of the host vehicle is a predetermined threshold or less, the guide unit leads the host vehicle to change lanes toward the travel route at a point before the distance from the position of the host vehicle to the branch point reaches the predetermined distance, wherein, when the determination unit determines that the accuracy of the travel lane of the host vehicle is the predetermined threshold or less, the guide unit leads the host vehicle to change the travel lane to a rightmost lane or a leftmost lane.
