Abstract: The disclosure relates to a computer-implemented method and device for the automated update of a communication unit of a control unit of a vehicle. The control unit includes a plurality of software clusters. The method includes providing the control unit of the vehicle, comprising a plurality of software clusters, a communication unit and a Multi Device Connector Routine. The communication unit is designed for handling communication between the software clusters and has a dedicated manifest and a configuration table for this purpose. The method includes updating at least one of the software clusters and executing the Multi Device Connector Routine, where at least the manifest of the updated software cluster is read in; at least one new manifest is generated for the communication unit by way of the read-in manifest; and at least one new configuration table is generated for the communication unit.
