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.

Abstract: A vehicle information communication system includes a center apparatus and a vehicle apparatus that includes a group of electronic control units (ECUs) and that sends vehicle configuration information including configuration information on the group of ECUs mounted in the vehicle to the center apparatus via wireless communications. The center apparatus performs a first determination of whether the vehicle configuration information received from the vehicle apparatus matches approved-configuration information registered in an approved-configuration database, and performs a second determination of whether software update data for at least one ECU of the group of ECUs mounted in the vehicle exists in an update database. When both the first and second determinations are true, the center apparatus sends the software update data for at least one ECU of the group of ECUs mounted in the vehicle to the vehicle apparatus via the wireless communications.
