Abstract
A map data output device includes: a map storage that stores map data that represents lane network information; a position determination portion that determines a current position of a vehicle; a read processing portion that reads the map data of an area established based on the current position; a control map generation portion that generates control map data obtained by adding information to the map; and an output portion that outputs the control map data to a vehicle control device.
Claims9
A map data output device comprising:
- a map storage configured to store map data that represents lane network information that shows a model of a lane of a road by connecting a link that indicates a part of the lane;
- a position determination portion configured to determine a current position of a vehicle;
- a read processing portion configured to read, from the map storage, the map data of an area established based on the current position determined by the position determination portion;
- a control map generation portion configured to generate control map data by adding information indicating lane shape information to the map data based on the map data read by the read processing portion;
- and
- an output portion configured to output the control map data to a vehicle control device configured to control behavior of the vehicle, wherein:
- the added information is the lane shape information and is defined as addition information;
- the map data represents lane shape information that indicates a shape of a lane for each link and is different from the addition information;
- and
- the control map generation portion is configured to generate the control map data obtained by adding the addition information to increase an information amount of the lane shape information in the read map data.

A map data output device comprising:
- one or more processors;
- and
- a memory that is configured to store map data that represents lane network information that shows a model of a lane of a road by connecting a link that indicates a part of the lane, and is coupled to the one or more processors and storing program instructions that when executed by the one or more processors cause the one or more processors to at least:
- determine a current position of a vehicle;
- read, from the memory, the map data of an area established based on a determined current position;
- generate control map data by adding information indicating lane shape information to the map data based on read map data;
- and
- output the control map data to a vehicle control device configured to control behavior of the vehicle, wherein:
- the added information is the lane shape information and is defined as addition information;
- the map data represents lane shape information that indicates a shape of a lane for each link and is different from the addition information;
- and
- the program instructions cause the one or more processors to generate the control map data obtained by adding the addition information to increase an information amount of the lane shape information in the read map data.
