Abstract

To provide a map delivery device, an onboard device that receives map data from the map delivery device, and a map delivery system configured such that the map delivery device and the onboard device can communicate with each other, the map delivery device being capable of reducing an amount of delivery data, reducing a communication cost, and preventing performance deterioration of map update processing by delivering update data narrowed down to a necessary range in accordance with a type of road in path information when updating map data along a path. (A map delivery device 10 of) a map delivery system 1 in the present embodiment manages map data by different section methods according to the type of road (expressway and general road), and delivers map data of different section methods according to the type of road in the path information. When the type of road in the path information is an expressway section, map data of a partitioning method in units of roads, which is managed along a route is delivered. When the type of road in the path information is a general road section, map data of a partitioning method in units of meshes, which is managed by dividing the road into predetermined regions is delivered.
