DATA DELIVERY SYSTEM, CONTROL SERVER, AND DATA DELIVERY METHOD

摘要

A data delivery system capable of reducing the processing load of a server is provided. A control server (200) is equipped with: a selection part (215) that selects telematics control units (TCU (300)) to which update data are to be delivered on the basis of levels of priority set in association with delivery target TCUs (300); a message generation part (216) that generates and transmits a message to the TCUs (300) selected by the selection part (215), said message inquiring whether or not the TCUs are ready to accept the update data; and a delivery control part (217) that, upon receiving response messages transmitted from the TCUs (300) in response to the transmitted message, selects a TCU (300) to which the update data are to be transmitted on the basis of the received response messages and requests that a delivery server (100) deliver the update data to the selected TCU (300).
