An in-vehicle update device acquires update information and update programs relating to a plurality of updates transmitted from an external server outside a vehicle, and performs a process for updating a program of an in-vehicle ECU. The in-vehicle update device comprises a control unit that is communicatively connected to the in-vehicle ECU and is for controlling the transmission of the update programs to the in-vehicle ECU. The control unit determines the order to transmit, to the in-vehicle ECU, the update programs corresponding to the respective updates on the basis of the update information, transmits to the in-vehicle ECU an update program corresponding to one of the updates on the basis of the determined transmission order, determines if the one of the updates in the in-vehicle ECU is successful or has failed, and, upon determining that the one of the updates is successful, transmits to the in-vehicle ECU the update program that is subsequent in the transmission order to the update program corresponding to the one of the updates.
车载更新装置取得从车外的外部服务器发送的与多次更新有关的更新信息及更新程序,并进行用于对车载ECU的程序进行更新的处理,其中,所述车载更新装置具备控制部,该控制部以能够通信的方式与车载ECU连接,并控制更新程序向车载ECU的发送,控制部基于更新信息,决定与多次更新分别对应的各个更新程序的向车载ECU的发送顺序,基于决定的发送顺序,将与多次更新中的一个更新对应的更新程序向车载ECU发送,判定车载ECU中的一个更新是否成功,在判定为一个更新成功的情况下,将与一个更新对应的更新程序的下一发送顺序的更新程序向车载ECU发送。
