Abstract: In one aspect of the present disclosure, a distribution package that is generated in advance is stored in a package DB, and information of a vehicle in which a target device is mounted is stored in a campaign DB. Vehicle related information includes a special flag indicating whether to generate a distribution package at that point in time. A package generation unit generates a distribution package upon receiving a package generation instruction and stores the distribution package in the package DB. When the special flag is in a reset state, the package generation unit reads the distribution package from the package DB and transfers the read distribution package to a package distribution unit. On the other hand, when the special flag is in a set state, the package generation unit generates a distribution package at that point in time.

Abstract: An individual vehicle information database of a center device has a waiting queue used to sequentially write a plurality of individual vehicle information transferred by an individual vehicle information registration unit. When attempting to transfer individual vehicle information sent from a master device to the individual vehicle information database, the individual vehicle information registration unit refers to the waiting queue, and if a write waiting number is less than a predetermined number, the individual vehicle information is stored in the waiting queue. If the write waiting number is at least the predetermined number, the individual vehicle information is stored in the waiting queue if any of individual vehicle information has content satisfying a write priority condition. If all of the individual vehicle information have content not satisfying the write priority condition, the vehicle information is not stored in the waiting queue.

Abstract: When configuration information regarding configurations of respective devices are received from electronic control units, the in-vehicle device generates a hash value based on data values of the configuration information, and transmits the hash value to a center device. The center device compares the hash value received from the in-vehicle device with a hash value of configuration information of the vehicle stored in a vehicle-side configuration information storage unit of the center device, and notifies the in-vehicle device of a full data transmission request for transmitting all data values of the configuration information when both of the hash values do not match each other. When the in-vehicle device is notified of the full data transmission request, the in-vehicle device transmits all of the data values of the configuration information to the center device.

Abstract: In an ECU reprogram data DB of a center device, data of an update program for a target ECU for a program update among a plurality of EUCs mounted in a vehicle is stored. In a configuration information DB, an “ECU ID” corresponding to each ECU and vehicle-related information such as an “ECU SW ID” for each application program stored in the ECU are stored along with the vehicle type. An ECU metadata database stores update data-related information pertaining to update data and attributes of the rewrite target ECU. A specification data generation unit generates specification data, based on the information stored in the configuration information database and the information stored in the ECU metadata database, to be transmitted to the vehicle together with update data to be written in the target ECU such that the data includes information related to the type, attributes, and update data for the target ECU and information indicative of a rewrite environment related to the data update.
