Abstract: A control unit system includes a control unit on which a rights management system is set up, access permission information being retrievably stored by the rights management system, functions in executable form being stored on further control units of the control unit system, at least one of the further control units being configured as a query control unit set up to execute these functions, or not, based on access permission information stored in the rights management system, characterized in that the control unit also includes a device management system that is configured to establish a connection with a server via a communication interface and to provide the rights management system with an update of the access permissions received from the server via this interface.

Abstract: In a method for storing data in a motor vehicle: an application software executed on a control device of the motor vehicle connects, via a communication network of the motor vehicle, to a data storage device of the motor vehicle; the application software logically connects the connected data storage device to the control device; the application software accesses the connected data storage device via the communication network, and the application software optionally releases the connected data storage device.

Abstract: A method for updating firmware of a vehicle via an air interface, in which data are exchanged with a backend via the air interface through a connection module, the data are managed by a data management module inside the vehicle, the connection module and the data management module are coordinated by a coordination layer, the connection module and the coordination layer are monitored by a monitoring layer, and the data are requested as needed by the coordination layer for an installation.

Abstract: A method is provided for regulating a Quality of Service in a local area network, including the following: a Quality of Service regulator receives at a gateway of the local area network, from at least one Quality of Service checker, a status report concerning a distributed application; the Quality of Service regulator establishes, based on the status report, traffic engineering rules pertaining to the gateway; and the Quality of Service regulator transmits the traffic engineering rules to a Quality of Service controller. A corresponding device, a corresponding computer program and a corresponding storage medium are also provided.

Abstract: A subsystem for a vehicle includes a device management client for exchanging device, vehicle, and diagnostic as well as software update information, which is connected to a device management server of the back-end via an air interface, a download client for downloading a software update from the back-end into the vehicle, which is connected to a download server of the back-end via an air interface, software update clients for applying the software update, which are connected to the download client and a vehicle update client for coordinating the software update, which is connected to the download client and the software update clients.
