A vehicle management server is configured to transmit, to a vehicle, an update program for updating an existing program of an electronic device mounted on the vehicle. The vehicle management server includes a communicator and a controller. The communicator is configured to communicate with the vehicle. The controller is configured to control an update process. The controller is configured to determine, depending on a type of the update program, whether to present, to a vehicle user, an indication related to the update process for the existing program using the update program, and transmit, when the controller determines to present the indication related to the update process to the vehicle user, information for causing a predetermined information terminal to display the indication related to the update process to the vehicle via the communicator.

Program update system and vehicle management server

A software update device is configured to control software update of an electronic control unit mounted on a vehicle. The software update device includes: one or more storage devices configured to store first software and second software for downloading update data of the electronic control unit from a server, the first software and the second software being different from each other; and one or more processors configured to download the update data from the server by executing any of the first software and the second software.

Software update device, update control method, and non-transitory storage medium

A server includes: a first storage device storing prerequisite condition information including one or more prerequisite conditions to be satisfied by a vehicle when updating of software of an electronic control unit installed in the vehicle is executed; and one or more processors configured to transmit the prerequisite condition information to the vehicle based on a request from the vehicle.

Server, update managing method, non-transitory storage medium, software updating device, center, and OTA master

A server is configured to distribute update data for software for an electronic control unit mounted on a vehicle. The server includes: a storage device that stores device identification information in which information that specifies a communication module mounted on the vehicle and information that specifies a portable terminal configured to communicate with an update control device mounted on the vehicle are associated with each other, and the update data; and a processor configured to determine whether communication with the update control device is possible, and transmit the update data to the portable terminal that is associated with the communication module when the determination unit determines that the communication with the update control device is not possible.
