Abstract: Driving assistance systems, methods, and programs accept an inputted planned travel route from the route guidance system, provide driving assistance of the vehicle on the planned travel route, based on driving assistance map data, and obtain, when versions of the route guidance map data and the driving assistance map data do not match each other, the driving assistance map data whose version matches the version of the route guidance map data from a map provider. Route guidance systems search for a planned travel route based on route guidance map data, provide guidance on the planned travel route, output the planned travel route to the driving assistance system, and obtain, when versions of the route guidance map data and the driving assistance map data do not match each other, the route guidance map data whose version matches the version of the driving assistance map data from a map provider.

Abstract: A driving assistance systems, methods, and programs are capable of communicating with a route guidance system that searches for a planned travel route of a vehicle and provides guidance on the planned travel route. The systems, methods, and programs accept, as input, the planned travel route from the route guidance system as a route for driving assistance and provide driving assistance of the vehicle on the route for driving assistance. The systems, methods, and programs accept, as input, when the planned travel route whose guidance is provided by the route guidance system no longer matches the route for driving assistance, the planned travel route from the route guidance system.

Abstract: A driving assistance system includes: a planned travel route obtaining unit that obtains a planned travel route for a vehicle; a switching point obtaining unit that obtains a switching point from a driving assistance section to a non-assistance section on the planned travel route; and a guide control unit that displays an indication for announcing switching from the driving assistance section to the non-assistance section, from a point shifted to a near side by a predetermined section from the switching point on the planned travel route.

Abstract: A driving assistance system includes a planned travel route acquirer, a driving assistance section acquirer, and a guide controller. The planned travel route acquirer acquires a planned travel route for a vehicle. The driving assistance section acquirer acquires a driving assistance section on the planned travel route. The guide controller presents at least one icon indicating a point of switching between the driving assistance section and a non-assistance section on the planned travel route.

Abstract: This invention provides technology that can provide a driver with an opportunity to decide whether or not to continue automatic drive control. A cancel point management system includes a cancel point collector that collects first notification information, indicating a manual cancel point which is a point where automatic drive control has been cancelled in response to operation by a driver in a notification vehicle, from the notification vehicle and a guide information distributer that distributes first guide information for showing the manual cancel point to a guide vehicle traveling on a road.

Abstract: The present invention provides technology that updates a map such that appropriate guidance can be provided near an intersection. A map data update system updates map data on a link-by-link basis and includes a link acquisition portion that acquires an existing link which is a link indicated by existing map data and a new link which is a link indicated by new map data, and a link update portion that updates the existing link with the new link based on a shape of a portion of the existing link connected to an intersection and a shape of a portion of the new link corresponding to the existing link, the portion being connected to the intersection.

Abstract: Provided is a technique for reducing a possibility that a route guide and driving control are respectively performed on roads which are not consistent with each other. A driving support system includes a route guide portion that specifies a traveling road for guide that is a road on which a vehicle is traveling, and that performs a route guide based on the traveling road for guide. The driving support system also includes a driving control portion that specifies a traveling road for control that is the road on which the vehicle is traveling, and that performs driving control based on the traveling road for control. The driving support system also includes a cancel control portion that cancels at least one of the route guide and the driving control when the traveling road for guide and the traveling road for control are not consistent with each other.
