This electronic control device (19) is equipped with: a difference data acquisition unit (103a) that acquires difference data which indicates a difference between old data and new data and which is data to be used for rewriting a data storage region of the electronic control device; a consistency determination unit (103b) that, on the basis of first determination information related to stored datastored in the data storage region and second determination information acquired in a format associated with the difference data, determines whether the difference data is consistent with the data storage region or the stored data; an update data restoration unit (103c) that, when the consistency determination unit has determined that the difference data is consistent with the data storage regionor the stored data, uses the difference data and the stored data to restore update data, which is new data; and a data writing unit (103d) that writes the update data, which has been restored by the update data restoration unit, to the data storage region.
电子控制装置(19)具备:差分数据获取部(103a),获取用于改写电子控制装置的数据储存区域的数据亦即表示旧数据与新数据的差分的差分数据;匹配性判定部(103b),基于与存储于数据储存区域的储存数据相关的第一判定信息、和以与差分数据相关联的方式获取的第二判定信息,判定该差分数据是否与数据储存区域或者储存数据匹配;更新数据复原部(103c),在通过匹配性判定部判定为差分数据的匹配性为正的情况下,使用差分数据和储存数据来复原新数据亦即更新数据;以及数据写入部(103d),将通过更新数据复原部复原的更新数据写入数据储存区域。
