Abstract
A system includes: a server configured to transmit map data of each of areas; and a vehicle including a storage device. In a case where map data of an area to which a current position of the vehicle belongs is not stored in the storage device, the vehicle transmits, to the server, an acquisition request to acquire map data of an acquisition area including at least the area and stores the map data of the acquisition area that is transmitted in response to the acquisition request in the storage device. In a case where a frequency index value is equal to or less than a predetermined threshold, when a predetermined condition is established, the vehicle deletes the map data of the acquisition area. In a case where the frequency index value is larger than the threshold, the vehicle maintains the map data of the acquisition area to be stored.
