Abstract
A plurality of control devices include a master control device and a slave control device. The master control device transmits, when software stored in a storage area different from the start storage area is updated in the slave control device, to the slave control device, a switching instruction for setting the storage area that stores the updated software as the start storage area. The slave control device implements, when receiving the switching instruction, setting of the storage area as the start storage area at a time of a next start, and requests, at every start, the master control device to execute consistency determination processing for determining whether pieces of identification information of the software stored in the start storage areas are consistent between the control devices. The master control device executes, when receiving the request from the slave control device, the consistency determination processing.
