Abstract

In a vehicle electronic control system, a vehicle master device is configured to acquire data storage bank information including information for specifying which bank is an active bank and information for specifying software versions of an active bank and an inactive bank from a rewrite target ECU that has a non-volatile memory with a plurality of data storage banks and to transmit the data storage bank information acquired by the data storage bank information acquisition unit to a center device. The center device is configured to select update data compliant to the inactive bank on the basis of the software versions and the active bank specified by the data storage bank information received from the vehicle master device and to transmit a distribution package including the update data selected by the update data selection unit to the vehicle master device.
