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: A vehicle information communication system including a center device and an in-vehicle device is provided. When pieces of configuration information regarding configurations of respective devices are received from electronic control units, the in-vehicle device transmits a configuration information list including the pieces of configuration information to the center device. The center device includes a configuration information storage unit storing the configuration information list approved with respect a vehicle type, compares the configuration information list received from the in-vehicle device with the configuration information list stored in the configuration information storage unit. When the center device determines that the configuration information list received from the in-vehicle device is disapproved, the center device transmits a presence of abnormality to the in-vehicle device.

Abstract: A center device includes an update data storage unit in which new data and new difference data for updating to the new data from old data are stored for, among electronic control units mounted on a vehicle, a target device targeted for data update. The center device generates, using the new data, a first verification value for verifying integrity in the vehicle, and generates, using the new difference data, a second verification value for verifying integrity of the new difference data in the vehicle. The center device generates a package including the new difference data, the first verification values and the second verification values for a plurality of the target devices. The center device generates, using the distribution package, a third verification value for verifying integrity of the distribution package in the vehicle, and transmits the distribution package along with the third verification value to the in-vehicle 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.
