Vehicle network system, control method of vehicle network system and manager control device applied to vehicle network system

A control method of a vehicle network system mounted on a vehicle and including a plurality of control devices communicable with each other,

• the plurality of control devices including:
• a management-target control device that retains cluster information indicative of a cluster to which the management-target control device belongs among a plurality of clusters being divisions, and that becomes an active state in response to an activation message from another control device including active-cluster information indicative of the cluster to be active that matches the cluster indicated by the cluster information;
• and
• a manager control device that includes a storage medium storing cluster setting information for configuring the cluster information of the management-target control device and has a function of configuring the cluster information of the management-target control device based on the stored cluster setting information,
• the control method comprising:
• the manager control device receiving, from an external device, for-update cluster setting information for updating the cluster setting information;
• and
• when receiving the for-update cluster setting information, the manager control device storing the for-update cluster setting information in a storage medium separate from the storage medium storing the cluster setting information or in a storage area separate from a storage area storing the cluster setting information.

• and
• the manager control device that includes a storage medium storing cluster setting information for configuring the cluster information of the management-target control device and has a function of configuring the cluster information of the management-target control device based on the stored cluster setting information,
• wherein:
• the manager control device is capable of receiving, from an external device, for-update cluster setting information for updating the cluster setting information;
• and
• when receiving the for-update cluster setting information, the manager control device stores the for-update cluster setting information in a storage medium separate from the storage medium storing the cluster setting information or in a storage area separate from a storage area storing the cluster setting information.
