A central gateway controller (100) for managing data which is transmitted via a vehicle electrical system of a vehicle is provided. The gateway controller includes at least one central communication server, ZKS, (110) including at least one central information store, ZIA, (120) for centrally storing data, which is transmitted via the vehicle electrical system, and at least one communication module (130, 132, 134, 136) for transmitting data between the ZIA and at least one bus system (160, 162, 164, 166) belonging to the vehicle electrical system. The gateway controller can store the data transmitted via the communication module in the ZIA in uniform data sets. The gateway controller is thus not just used to route messages between different (message) producers or generators and (message) consumers or loads in the vehicle electrical system but is also capable of storing the data to be exchanged in the ZIA in a uniform format.

A path between a first sender and a first receiver in the topology of the actual network differs from the path between the first sender and the first receiver in the topology of the target network, wherein in the actual network at least one first message of the first sender is received through a first network interface by a gateway having at least two network interfaces, is delayed by a delay, and is sent through a second network interface on a path to the first receiver.

A bus node is capable of performing a method, for the assigning of bus node addresses to bus nodes of a serial data bus. The method is performed with the aid of bus shunt resistors in the individual bus nodes of the data bus system in an assignment time period. After the assigning of bus node addresses to the bus nodes in the assignment time period, there follows an operating time period. For this purpose, the bus node comprises such a bus shunt resistor. The bus node is characterized by a bus shunt bypass switch which, prior to assigning a bus node address to the bus node in the assignment time period is opened and which after the assignment of bus node address to the bus node in the assignment time period is closed, and which is closed in the operating time period.

Among serial communication systems between vehicle-mounted communication units, a serial communication system for improving use efficiency of a communication bandwidth in a communication standard LIN has been required. In order to solve this problem, in a serial communication system of LIN, a response of a master node as a write request transmitted from the master node to a slave node and a response of the slave node transmitted from the slave node to the master node are combined into a time base, and a certain period for receiving a response from the slave node is provided after the write request from the master node.
