A master device (3) is provided with: a download execution unit (9a) that downloads a first packet corresponding to a first system and a second packet corresponding to a second system from a center device; an update data extraction unit (9b) that extracts update data from the first packet and the second packet; a mounting instruction unit (9c) that instructs the electronic control device to be written with the update data to be mounted; and an activation instruction unit (9d) that instructs the electronic control device to be written to activate the update data after the installation of the update data in the electronic control device to be written is completed. When updating data is installed in the electronic control devices of all first writing objects corresponding to the first system and the electronic control devices of all second writing objects corresponding to the second system, the electronic control devices of all first writing objects corresponding to the first system and the electronic control devices of all second writing objects corresponding to the second system are updated. The activation instruction unit instructs, at the same timing, activation update data to all of the electronic control devices of the first write object and all of the electronic control devices of the second write object.
本发明提供主装置(3),具备:下载执行部(9a),从中心装置下载与第一系统对应的第一数据包以及与第二系统对应的第二数据包;更新数据提取部(9b),从第一数据包和第二数据包提取更新数据;安装指示部(9c),对写入对象的电子控制装置指示安装更新数据;以及激活指示部(9d),当在写入对象的电子控制装置中完成安装更新数据后,对写入对象的电子控制装置指示激活更新数据。当在与第一系统对应的所有第一写入对象的电子控制装置以及与第二系统对应的所有第二写入对象的电子控制装置中完成安装更新数据后,激活指示部在相同的定时对所有第一写入对象的电子控制装置以及所有第二写入对象的电子控制装置指示激活更新数据。
