Vehicle communication management system

A vehicle communication management system comprising:

• a communicator configured to communicate with an outside of a first vehicle to which the vehicle communication management system is configured to be applied;
• a vehicle position identifier configured to identify a current position of the first vehicle;
• and
• a manager configured to manage the communicator, wherein
• the manager comprises
• one or more processors, and
• one or more memories communicably coupled to the one or more processors,
• the one or more memories comprising a storage, the storage being configured to hold amounts of downloadable data, the amounts of the downloadable data being linked with respective pieces of position data, based on communication states for the respective pieces of the position data,
• the one or more processors being configured to
• calculate an amount of download data necessary for the first vehicle,
• accumulate the amounts of the downloadable data until the first vehicle reaches a point where the communication state deteriorates, based on:
• route data on a route along which the first vehicle is likely to pass before reaching the point where the communication state deteriorates;
• the amounts of the downloadable data for the respective pieces of the position data held in the storage;
• and passing time periods for the respective pieces of the position data on the route along which the first vehicle is likely to pass before reaching the point where the communication state deteriorates, and
• cause the communicator to start downloading the download data necessary for the first vehicle, at a point where a sum total of the accumulated amounts of the downloadable data becomes larger than the calculated amount of the download data necessary for the first vehicle.
