Publication number: 20210157566Abstract: 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.Type: ApplicationFiled: February 3, 2021Publication date: May 27, 2021Inventors: Nao SAKURAI, Shuhei TAKAHASHI, Yuzo HARATA, Kazuhiro UEHARA, Takuya HASEGAWA, Takuya KAWASAKI, Kazuaki HAYAKAWA
