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 electronic control system includes a center device and a master device and a data relay device capable of performing data communication therebetween. The center device obtains campaign information of the program update, transmits the obtained campaign information to the data relay device, and transmits the update data to the data relay device. When receiving the campaign information from the center device, the data relay device changes setting of the received campaign information and delivers the information to the master device, and, when receiving the update data from the center device, the data relay device delivers the received update data to the master device. When receiving the campaign information from the data relay device, the master device instructs a target electronic control device to update the program with the update data received from the data relay device according to the received campaign information.

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.
