Abstract
A plurality of in-vehicle information collecting devices mounted on a plurality of vehicles; a center server to manage each in-vehicle information collecting device as a communication target; and a communication unit to relay communication between each in-vehicle information collecting device and the center server are included. Each in-vehicle information collecting device has an in-vehicle controller to transmit/receive information including vehicle information to/from the center server, and the center server includes a server controller to transmit/receive information to/from each in-vehicle controller. The server controller, when receiving the vehicle information from each in-vehicle controller, analyzes the received vehicle information, generates speed information defining a transmission speed of the vehicle information based on an analysis result, and transmits the generated speed information to each in-vehicle controller. Each in-vehicle controller controls a communication amount of the vehicle information to the server controller, based on the speed information received from the server controller.
