As one embodiment of the present disclosure, an OTA center (1) transmits, to an OTA host (32), RP metadata having a three-tier structure comprising a distribution tier that stores a communication protocol and communication destination information, a host tier that stores information pertaining to a platform of the OTA host (32), and a target tier that stores information pertaining to a platform of a target ECU (33). And represents configuration information of the distribution packet. When the OTA host (32) interprets the RP metadata and determines that the RP metadata is suitable for a distribution packet of the host vehicle, the OTA host (32) requests, from the OTA center (1), DL metadata that stores control information for acquiring necessary data in accordance with each layer. When an OTA center (1) transmits DL metadata to an OTA host (32), the OTA host (32) interprets the DL metadata, acquires necessary data, and performs data update control of a target ECU (33).

    作为本公开的一方式,OTA中心(1)向OTA主机(32)发送RP元数据,该RP元数据为由储存通信协议以及通信目的地信息的分发层、储存与OTA主机(32)的平台相关的信息的主机层、以及储存与目标ECU(33)的平台相关的信息的目标层构成的三层结构,且表示分发数据包的构成信息。OTA主机(32)若对RP元数据进行解释判断为适合于本车辆的分发数据包,则向OTA中心(1)要求储存用于与各层对应地获取需要的数据的控制信息的DL元数据。若OTA中心(1)将DL元数据发送到OTA主机(32),则OTA主机(32)对DL元数据进行解释来获取需要的数据并进行目标ECU(33)的数据更新控制。
