In the present invention, an outside-vehicle communication unit (111) receives, from a server (200), update information including: information indicating an update target device to be a software update target from among a plurality of devices (100A-100E); and information indicating a generation source device, among the plurality of devices (100A-100E), that has generation source software serving as a source for generating update data to be used for updating update target software included in the update target device. On the basis of the update information, when the device is a generation source device, the update data generation unit (112) generates update data using generation source software included in the device. On the basis of the update information, when the device is a device to be updated, the software update unit (113) uses the update data generated by the generation source device to update the software to be updated of the device.
本发明中,车外通信部(111)从服务器(200)接收更新信息,该更新信息包括:表示从多个设备(100A~100E)中成为软件更新对象的更新对象设备的信息;以及表示多个设备(100A~100E)中具有生成源软件的生成源设备的信息,该生成源软件成为生成被用于更新更新对象设备所具有的更新对象软件的更新用数据的源。更新用数据生成部(112)基于更新信息,在本设备为生成源设备的情况下,使用本设备所具有的生成源软件来生成更新用数据。软件更新部(113)基于更新信息,在本设备是更新对象设备的情况下,使用生成源设备生成的更新用数据来更新本设备所具有的更新对象软件。
