Abstract: A center that is configured to communicate with an Over-The-Air (OTA) master that controls software update for an electronic control unit mounted on a vehicle is provided. The center includes one or more processors configured to determine availability of permission frames when an inquiry for software update is received from the OTA master and update data for the electronic control unit exists, and, when at least one of the permission frames is available, allocate the permission frame available among the permission frames to the OTA master and permit update processing. The one or more processors are configured to determine availability of a multiplex frame when a transmission request for the distribution package is received from the OTA master, and, when at least one of the multiplex frames is available, allocate a multiplex frame available among the multiplex frames to the OTA master and control transmission of the distribution package.

The server includes: a communication module configured to receive usage information representing a usage state of the vehicle, and transmit the update data to the vehicle; and one or more processors configured to control, based on the usage information, at least one of a timing or a communication speed of transmitting the update data to the vehicle by the communication module.

Abstract: A software update apparatus includes a communication unit that sends a request for downloading update data to a center, a storage unit that stores the downloaded update data, and a control unit that executes, based on the update data, a control for installing, or installing and activating update software on one or more target electronic control units from among a plurality of electronic control units connected to each other via an in-vehicle network. The control unit acquires software versions of the electronic control units, determines whether there is a consistency in a combination of the acquired software versions, and executes, upon determining that there is an inconsistency in the combination of the acquired software versions, a process for attaining the consistency in the combination of the software versions.

Abstract: A software update apparatus includes a communication unit that sends a request for downloading update data to a center, a storage unit that stores the downloaded update data, a control unit that executes, based on the update data, a control for installing, or installing and activating update software on one or more target electronic control units from among a plurality of electronic control units connected to each other via an in-vehicle network, and a determination unit that determines whether the vehicle is stopped and can be maintained in a stopped state. When a determination result of the determination unit is positive, the control unit restricts operations of the target electronic control units and executes the control for installing, or installing and activating.
