Abstract
A vehicle master device is configured to distribute update data received from a center device to a rewrite target electronic control unit (ECU) and to instruct the rewrite target ECU to write the update data. The vehicle master device includes at least one processor programmed to: transmit a software version and a configuration setting information version as configuration information of the rewrite target ECU to the center device; download rewrite specification data from the center device upon determining that there is a campaign notification relating to a program update based on a notification from the center device; and instruct the rewrite target ECU to rewrite configuration setting information by overwriting using new configuration setting information downloaded from the center device upon determining that the configuration setting information is to be rewritten based on the rewrite specification data.
