    摘要: Provided is lane guidance system for decreasing the possibility that a user is misled including: a proposed travel route acquisition unit that acquires a proposed travel route of a vehicle; a successive intersection determination unit that determines whether a distance between a first intersection that is a guidance intersection on the proposed travel route and a second intersection that follows the first intersection is within a prescribed distance. Based on the proposed travel route, a travelable lane acquisition unit acquires a travelable lane that the vehicle needs to travel along when entering the first intersection to exit in a specific exiting direction of the first intersection, when the vehicle needs to exit from the first intersection in the exiting direction to travel along the proposed travel route. Before arriving at the first intersection, the lane guidance unit selects and proposes, as a recommended lane from the travelable lane, a lane that the vehicle needs to travel along when entering the first intersection after exiting from the first intersection, a lane that the vehicle needs to travel along when entering the second intersection to exit in a specific exiting direction of the second intersection, when the vehicle needs to exit from the second intersection in the exiting direction to travel along the proposed travel route when the a distance between the first intersection and the second intersection is within a prescribed distance.

    摘要: A route search system includes an electronic control unit configured to perform: acquiring estimated weather information, the estimated weather information being information about weather that is estimated in a region where a candidate of a first route from a departure place to a destination place exists; acquiring experienced weather information, the experienced weather information being information about weather that a user has experienced in past; an searching the first route by preferentially selecting a first road over a second road, and outputting information about the first route, the first road being a road in a first region where the estimated weather information coincides with the experienced weather information, the second road being a road in a second region where the estimated weather information does not coincide with the experienced weather information.

    摘要: A route search system including an electronic control unit configured to perform: acquiring estimated weather information, the estimated weather information being information about weather that is estimated in a region where a candidate of a first route from a departure place to a destination place exists; acquiring reference weather information, the reference weather information being decided based on statistical information about weather information in a predetermined behavior range of a user; and searching the first route by preferentially selecting a first road over a second road, and outputting information about the first route, the first road being a road in a first region where the estimated weather information is not worse than the reference weather information, the second road being a road in a second region where the estimated weather information is worse than the reference weather information.
