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: 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.

Abstract: A vehicle information communication system including a center apparatus and a vehicle apparatus is provided. The vehicle apparatus is mounted in a vehicle and includes electronic control units (ECUs) each associated with a respective ECU software identifier (SWID). The vehicle apparatus send the ECU SWIDs of the ECUs to the center apparatus via the wireless communications. When all of the ECU SWIDs received from the vehicle apparatus are included in any one of approved ECU SWID combinations and software update data exists for at least one of the ECUs, the center apparatus sends the software update data to the vehicle apparatus via the wireless communications. The vehicle apparatus performs ECU software update based on the software update data sent from the center apparatus.

Abstract: In a vehicle information communication system, a center device includes an individual vehicle configuration information storage unit in which configuration information transmitted from a plurality of vehicles is stored in such a form that transmission timings are specifiable, a campaign information storage unit in which campaign identification information and target vehicle identification information for identifying data update target vehicles are stored as campaign information related to data update for vehicle. The center device refers to the campaign storage unit and the individual vehicle configuration information storage unit, and when there is no transmission of the configuration information from the target vehicle for a predetermined period of time, transmits a message for urging data update to the in-vehicle device of the target vehicle.
