A master includes: a communication module configured to request a download of update data from a center; a first storage device configured to store the update data obtained by the download; and one or more processors configured to at a time of execution of the download, check at least one of a free space size of the first storage device or a free space size of a second storage device of each of one or more update-target in-vehicle devices among a plurality of in-vehicle devices connected through an in-vehicle network, and perform control such that, based on the update data, update software is installed, or installed and activated, in the one or more update-target in-vehicle devices, wherein the communication module is configured to request the download of the update data from the center based on the free space size.

Software update apparatus, master, OTA master, and network system

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.

Software update apparatus, software update method, non-transitory storage medium storing program, vehicle, and OTA master

A software update device is configured to be controlled in response to a request from a mobile terminal device. The software update device includes one or more processors configured to: acquire cooperation information indicating that connection of the mobile terminal device to a vehicle is made; and manage whether the mobile terminal device is permitted to execute interface processing related to software update, which is determined in accordance with at least the cooperation information.

Software update device, software update method, and center

A server configured to transmit update data used in updating software of an in-vehicle device of a vehicle to the vehicle. 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.

Server, software updating device, vehicle, software updating system, control method, and non-transitory storage medium

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.

A software update device connected to an in-vehicle network including a plurality of in-vehicle devices includes one or a plurality of processors configured to: perform an update of software of at least one of the in-vehicle devices; and perform a control of setting a door of a vehicle in an unlocked state before performing predetermined processing included in processing for the update, when performing the update.
