It is an object to provide technology allowing for appropriate control of a lighting apparatus to illuminate a road from a vehicle. An acquisition unit acquires position information of the vehicle, travel lane information indicating a travel lane in which the vehicle is traveling, and road information. A controller performs control to cause the lighting apparatus to illuminate a branching road directly connected to the travel lane in a first illumination manner when it is determined, based on the position information, the travel lane information, and the road information, that there is the branching road and the vehicle is traveling a first illumination section satisfying a predetermined positional relationship with a branching point of the branching road from the travel lane.

Driving assistance apparatus and driving assistance method

It is an object of the present disclosure to provide a technique to make it possible to reduce data size of a file used for managing an update of a mesh file. A map data update apparatus updates a specific mesh file on the basis of an update necessity management file having a bit array in which respective positions of a plurality of bits are associated with respective mesh IDs of a plurality of mesh files, in which 1-bit flag information indicating the necessity of an update of the mesh file is stored at the position corresponding to the mesh ID of the mesh file in the bit array and the mesh ID of the specific mesh file.

Map data update apparatus and map data update method

It is an object of the present invention to provide a technique capable of reducing a difference between a three-dimensional shape represented by map data, using approximation, and a real three-dimensional shape. A map data generating apparatus is a map data generating apparatus capable of generating map data representing a three-dimensional shape, using approximation, the map data generating apparatus including: an acquisition part that acquires a shape point sequence indicating the three-dimensional shape, and a control part that generates an arc passing three object points, based on the three object points in the shape point sequence acquired by the acquisition part, and determines whether an approximation division point that should not be approximated in the three-dimensional shape is included in the three object points, based on the arc.

Map data generating apparatus, terminal apparatus, and map data generating method

A lane recognition apparatus according to the present invention includes: a subject vehicle position calculation unit that calculates a current position of a subject vehicle; a traveling lane estimation unit that estimates a lane in which the subject vehicle is traveling and a position, in a direction perpendicular to a traveling direction, of the subject vehicle in the lane based on the current position of the subject vehicle, subject vehicle surroundings information indicating a positional relationship between a road structure being a three-dimensional structure existing in relation to a road and the subject vehicle, and road information associating the road structure with a lane of a road in terms of a positional relationship therebetween; and a traveling lane final determination unit that determines the lane in which the subject vehicle is traveling and the position of the subject vehicle in the lane based on results of estimation.

Lane recognition apparatus and lane recognition method

A map information processing apparatus includes a map information storage unitfor storing map information which is separated into multiple layers, a layer-to-be-updated-with-addition determination processing unitfor determining one or more layers which are to be updated with addition of an unregistered road which has been detected during travel of a vehicle, and an unregistered road adding and updating unitfor adding the unregistered road to the map information storage unit to update the map information with the addition being aimed at the one or more layers determined by the layer-to-be-updated-with-addition determination processing unit.

Map information processing apparatus

A map information processor includes a map information storage unitfor storing map display information including a set of pieces of mesh-by-mesh map information managed on a mesh-by-mesh basis and including road information, background information, and in-mesh image information, an image processing unitfor generating a map image on a basis of image data included in the road information, the background information, and the in-mesh image information included in the mesh-by-mesh map information read from the map information storage unit, and a display devicefor displaying the map image generated by the image processing unit.

Map information processor and data structure of map information

A map information processing device includes a map information storage unitfor storing map information, a sensor information input unitfor inputting sensor information used for calculation of a current position, a navigation processing unitfor calculating the current position by using the map information read from the map information storage unit, and the sensor information inputted from the sensor information input unit, and for, when determining that the above-mentioned calculated current position is in a tunnel shown by the read map information, and when this tunnel branches into tunnel sections at a forward position, calculating a distance to each of all tunnel end points to generate a map image about a map including this calculated distance, and an output control unitfor outputting the map image generated by the navigation processing unit.

Map information processing device

A map information processing apparatus is disclosed. The apparatus includes a processor for calculating a vehicle position; a data generation unit for generating traveling locus data on the basis of the calculated vehicle position when the vehicle position deviates from a road; a registration unit for registering the traveling locus data generated by the data generation unit in a temporarily registered road list as a temporarily registered road; an operation unit for selecting one of temporarily registered roads registered in the temporarily registered road list; and an official registration unit for registering the selected temporarily registered road in an officially registered road list as an officially registered road in accordance with an instruction from the operation unit, generating road data on the basis of traveling locus data relating to the temporarily registered road, and adding the generated road data to a map data stored in a map data storage unit.

A map information providing system has a map information providing apparatusand an onboard information terminal. The map information providing apparatusselects a road represented by the coordinate point string data indicating a newly established road in accordance with distribution request information obtained from the onboard information terminal, and distributes the distribution road information containing the coordinate point string data about the road selected to the onboard information terminal. The onboard information terminal obtains the distribution road information containing the coordinate point string data from the map information providing apparatus, and generates, in the same format at least in part as the map information, road data for adding a new road to a road network represented by the map information stored in a map information storing section from the coordinate point string data contained in the distribution road information obtained, and generates new map information from the road data and map information.
