This vehicular electronic control system (1) comprises a second device (13) equipped with: a file-to-be-transferred specification unit (82a) that specifies, as a file to be transferred, a file containing update data to be written to a third device; a first data size specification unit (82b) that specifies a first data size for acquiring the file to be transferred specified by the file-to-be-transferred specification unit; and an update data distribution unit (73) that uses a divided file transferred from a first device to distribute the update data to the third device. The first device is equipped with an update data transfer unit (64) that transfers the update data by dividing the file to be transferred specified by the file-to-be-transferred specification unit in accordance with the first data size specified by the first data size specification unit, and then transferring the divided file to the second device.
在车辆用电子控制系统(1)中,第二装置(13)具备:传输对象文件确定部(82a),确定包含写入到第三装置的更新数据的文件作为传输对象文件;第一数据大小确定部(82b),确定用于获取由传输对象文件确定部确定出的传输对象文件的第一数据大小;以及更新数据分发部(73),使用从第一装置传输的分割文件,将更新数据分发给第三装置。第一装置具备通过根据由第一数据大小确定部确定出的第一数据大小分割由传输对象文件确定部确定出的传输对象文件,并将该分割文件传输给第二装置,来传输更新数据的更新数据传输部(64)。
