Information communication system, information communication method, and server

An information communication method in an information communication system comprising:

• a plurality of in-vehicle information collecting devices individually mounted on a plurality of vehicles;
• a center server configured to manage each of the plurality of in-vehicle information collecting devices as a communication target;
• and
• a communication unit configured to relay communication between each of the plurality of in-vehicle information collecting devices and the center server, wherein
• each of the in-vehicle information collecting devices
• includes an in-vehicle controller configured to transmit/receive information including vehicle information on each of the vehicles, to/from the center server via the communication unit,
• the center server
• includes a server controller configured to transmit/receive information to/from an in-vehicle controller of each of the in-vehicle information collecting devices via the communication unit, the information communication method comprising:
• analyzing, when the server controller receives the vehicle information from each the in-vehicle controller, the received vehicle information;
• generating, by the server controller, speed information defining a transmission speed of the vehicle information, based on an analysis result in the analyzing;
• transmitting, by the server controller, the speed information generated in the generating to each the in-vehicle controller;
• and
• controlling, when each the in-vehicle controller receives the speed information from the server controller, a communication amount of the vehicle information to the server controller based on the received speed information.

A server for managing, as a communication target, each of a plurality of in-vehicle information collecting devices individually mounted on a plurality of vehicles, the server comprising a controller configured to transmit/receive information to/from each of the in-vehicle information collecting devices via a communication unit, wherein

• the controller,
• when receiving vehicle information from each of the in-vehicle information collecting devices, analyzes the received vehicle information;
• generates speed information defining a transmission speed of the vehicle information in each of the in-vehicle information collecting devices based on an analysis result;
• and transmits the generated speed information to each of the in-vehicle information collecting devices.
