摘要： 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.

摘要： 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.

摘要： Autonomous driving assistance systems, methods, and programs obtain lane information of a road on which a vehicle is traveling, and set a planned target section for which a lane change plan of the vehicle is to be created. The systems, methods, and programs obtain, for each lane, an obstructive factor present on the road on which the vehicle is traveling and that obstructs continuation of autonomous driving assistance executed on the vehicle, and set, for each obtained obstructive factor, an avoidance route that passes through a lane avoiding the obstructive factor. The systems, methods, and programs create a lane change route that defines the lane change plan of the vehicle in the planned target section and that is set so as to preferentially pass through the avoidance route set for each obtained obstructive factor, and execute the autonomous driving assistance of the vehicle based on the lane change route.

摘要： 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.

摘要： There is provided a technique for arranging characters along a road to improve appearance and readability. A map display system includes a temporarily arranging part that obtains directions of a plurality of characters for when the plurality of characters are temporarily arranged along a road in a direction of the road, the direction of the road being a reference direction; and an arranging part that arranges, when a difference between directions of consecutive characters is greater than or equal to a threshold value, the consecutive characters so as to reduce the difference, the consecutive characters being two consecutive characters in the direction of the road, and arranges, when the difference is less than the threshold value, the consecutive characters in a temporary arrangement position.

摘要： 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.

摘要： Autonomous driving assistance systems, methods, and programs obtain road information that specifies classification of lanes located ahead in a direction in which a vehicle is traveling and road connection for each lane. The systems, methods, and programs specify, based on the road information, a planned route that is to be taken by the vehicle on a presumption that the vehicle travels without changing lanes, when the vehicle travels with autonomous driving assistance, and execute the autonomous driving assistance for the vehicle according to the specified planned route.
