Abstract: 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.

Abstract: A software update device configured to control software update of an electronic control unit mounted on a vehicle, the software update device includes one or more processors configured: to download update data of software of the electronic control unit from a server; to transmit a validity confirmation request for confirming whether the update data is valid to the server before the update data is installed, to receive a confirmation result indicating whether the update data is valid from the server; to control the software update of the electronic control unit; and not to install the update data when the one or more processors determine that the update data is invalid based on the confirmation result received by the one or more processors.

Abstract: A center is configured to communicate with an OTA master configured to control software update of an electronic control unit installed in a vehicle. The center includes one or more processors configured to: receive a notification indicating progress of software update processing of the electronic control unit from the OTA master; manage an update status indicating an processing state of the software update processing in the vehicle based on the notification received by the one or more processors; and when the one or more processors receive a third notification following a first notification, set the update status based on the third notification, the third notification being different from a second notification scheduled to be received following the first notification.

Abstract: A center, configured to communicate with an OTA master configured to control software updating of an electronic control unit via a first network, includes a processor. The electronic control unit is installed in a vehicle. The processor is configured to store vehicle management information including key information used for authenticating the vehicle, receive an authentication signal from the vehicle via the first network. The authentication signal is signed using a unique key imparted to predetermined equipment installed in the vehicle. The processor is configured to perform authentication of the vehicle based on the vehicle management information and the authentication signal, and when the processor receives the key information from the vehicle, rewrites the vehicle management information stored by the processor based on the key information.
