A map data update system includes a first storage portion that stores road network data that describes a road in terms of a connection relationship between a node and a link; an update portion that receives update data and updates the road network data based on the update data; a data obtaining portion that obtains additional data by a means that differs from a means that receives the update data; a second storage portion that stores the additional data including association information that indicates association between the additional data and the link; and a correcting portion that, when update processing of the road network data is executed by the update portion, the association information in the additional data that is associated with the link that is changed by the update processing.
摘要:
A wrong-way-travel warning device comprising a vehicle speed detecting part configured to detect a vehicle speed of a vehicle, a part configured to detect a position of the vehicle, an angle detecting part configured to detect an angle of a vehicular longitudinal direction of the vehicle relative to a lane marking if the vehicle speed of the vehicle becomes less than or equal to a predetermined value, and a warning part configured to issue a warning to an occupant if the position of the vehicle is on a main lane of a highway and if the angle becomes about 90 degrees, is provided.

摘要:
A vehicle location recognition apparatus includes a link determination unit which accurately determines a link traveled by a vehicle from among a plurality of links meeting at a narrow-angle branch point, on the basis of vehicle location information and road information, travel history information representing a route traveled by the vehicle at the branch point. The vehicle location recognition apparatus includes a history information generation unit for generating travel history information for the determined link. The travel history information is stored in a learning database. On the basis of the travel history information, a learning unit generates learned priority information representing the priorities of the respective links meeting at a branch point and used in the determination by the link determination unit.

Apparatuses, methods, and programs acquire vehicle position information that represents a current position of a vehicle, acquire image information of a vicinity of the vehicle, and carry out image recognition processing of a target feature that is included in the image information to determine a position of the target feature. The apparatuses, methods, and programs store recognition position information that is based on the acquired vehicle position information and that represents the determined recognition position of the target feature. The apparatuses, methods, and programs determine an estimated position of the target feature based on a set of a plurality of stored recognition position information for the target feature, the plurality of stored recognition position information for the target feature being stored due to the target feature being subject to image recognition processing a plurality of times.
摘要:
Apparatuses, methods and programs store a plurality of target types, each target type having recognition attribute information indicating the likelihood that the target type will be recognized based on a type of road or a type of area. The apparatuses, methods and programs acquire vehicle position information indicating a current position of a vehicle, acquire image information in the vicinity of the vehicle, and acquire road attribute information about a road on which the vehicle is traveling, the road attribute information acquired based on the vehicle position information. The apparatuses, methods and programs determine a target type defining a target for image recognition within the image information, the target type being determined based on the acquired road attribute information and the stored recognition attribute information, and perform image recognition of a target feature included in the image information, the target feature being of the determined target type.
摘要:
Vehicle-position-recognition apparatuses, methods, and programs acquire current position information indicating a current position of a vehicle and acquire road information indicating at least one road based on a connection relationship between plural links. The apparatuses, methods, and programs determine a link where the vehicle travels based on the current position information and the road information and generate travel-history information indicating a route that the vehicle travels at a point where a link is branched based on the determined link. The apparatuses, methods, and programs acquire an image of an area surrounding the vehicle, recognize a recognition target in the acquired image, and store the generated travel-history information in the memory in association with information indicating the recognition of the recognition target. The apparatuses, methods, and programs generate learning-priority information indicating a priority of each link branched out at the branch point based on the stored travel-history information and the stored recognition information, the generated learning-priority information usable to determine on which of the links branched out at the branch point that the vehicle is traveling.
摘要:
Systems, methods, and programs capture an image of a periphery of a vehicle. The systems, methods, and programs, store predetermined patterns representing conditions of road markings formed on a road surface, detect a road marking on the basis of the captured image, and compare the detected road marking to the predetermined patterns. If the detected road marking matches one of the predetermined patterns, the systems, methods, and programs execute a predetermined action associated with the matching predetermined pattern.
