PROBLEM TO BE SOLVED: To efficiently transmit an update program while suppressing a processing load on a server.SOLUTION: A relaying device for relaying an update program for an on-vehicle control device to the on-vehicle control device includes: a first communication unit for communicating with a server for the update program via a mobile communication network; a second communication unit performing inter-vehicle communication with another vehicle; an in-vehicle communication unit for transmitting the update program received from the first or second communication unit to the on-vehicle control device; and a processing unit for controlling the second communication unit so as to receive the update program from the other vehicle, when there is another vehicle selectable as a transfer source of the update program by the inter-vehicle communication.SELECTED DRAWING: Figure 1

    【課題】サーバの処理負荷を抑制しつつ、効率的に更新プログラムを伝送する。【解決手段】車載制御装置の更新プログラムを車載制御装置に中継する中継装置は、更新プログラムのサーバと移動体通信網を介して通信する第1通信部と、他車両と車車間通信を行う第2通信部と、第1又は第2通信部から受信した更新プログラムを車載制御装置に送信する車内通信部と、車車間通信による更新プログラムの転送元として選択可能な他車両が存在する場合に、更新プログラムを他車両から受信するように第2通信部を制御する処理部と、を備える。【選択図】図1
