To provide an on-vehicle update device, etc. capable of appropriately coping with updates executed a plurality of times continuously by determining whether or not an update is successful in executing updates of an on-vehicle ECU program a plurality of times continuously.SOLUTION: An on-vehicle update device for acquiring update information and an update program on a plurality of times of updates transmitted from an external server outside a vehicle, and executing processing for updating a program on an on-vehicle ECU includes a control unit communicably connected to the on-vehicle ECU for controlling the transmission of the update program to the on-vehicle ECU. The control unit determines a transmission order to the on-vehicle ECU of the respective update programs corresponding to the plurality of times of respective updates on the basis of the update information, transmits the update program corresponding to one update of the plurality of times of updates to the on-vehicle ECU on the basis of the determined transmission order, and, transmits an update program on the transmission order next to the update program corresponding to the one update, to the on-vehicle ECU when it is determined whether or not the one update in the on-vehicle ECU is successful, and it is determined that the one update is successful.SELECTED DRAWING: Figure 2
【課題】車載ECUのプログラムの更新を複数回連続して行う際に更新の成否を判定することにより、複数回連続して行う更新に適切に対応することができる車載更新装置等を提供する。【解決手段】車載更新装置は、車外の外部サーバから送信される複数回の更新に関する更新情報及び更新プログラムを取得し車載ECUのプログラムを更新するための処理を行う車載更新装置であって、車載ECUと通信可能に接続され車載ECUへの更新プログラムの送信を制御する制御部とを備え、制御部は、更新情報に基づき複数回の更新夫々に対応する更新プログラム夫々の車載ECUへの送信順番を決定し、決定した送信順番に基づき複数回の更新の内の一の更新に対応する更新プログラムを車載ECUに送信し、車載ECUにおける一の更新の成否を判定し一の更新が成功したと判定した場合、一の更新に対応する更新プログラムの次の送信順番の更新プログラムを車載ECUに送信する。【選択図】図2
