Abstract: The disclosure relates to a method for determining an electrical system state of at least one motor vehicle, wherein electrical state data of the at least one motor vehicle are detected on the vehicle side by means of a power distribution unit in the at least one motor vehicle, wherein the detected electrical state data are transmitted to a central server by means of a communications interface, wherein the transmitted electrical state data are compared on the server side with at least one reference value, and wherein, starting from a comparison result, the electrical system state of the at least one motor vehicle is determined and provided. The disclosure further relates to a system for determining an electrical system state of at least one motor vehicle, a motor vehicle, and a central server.

Abstract: A method for the maintenance of vehicle components is disclosed. The operating points of a plurality of vehicle components are captured over a first time period ?t1 and first developments of the plurality of operating points over time in the first time period ?t1 are determined. The operating points of the plurality of vehicle components are captured over a second time period ?t2 different from the first time period ?t1 and second developments of the plurality of operating points over time in the second time period ?t2 are determined. By comparing the first developments and the second developments of the operating points of the plurality of vehicle components over time, it is determined whether the second development of the operating point of a vehicle component over time deviates from the first development of the operating point of said vehicle component over time by more than a predefined limit value.

Abstract: A network, in particular in a motor vehicle, wherein the network includes a central subscriber and at least one first subscriber, wherein the central subscriber and the at least one first subscriber are interconnected by way of at least one first cable. The central subscriber has at least one signal coupling unit and at least one energy coupling unit, wherein by way of the signal coupling unit an AC voltage can be impressed on at least one first line of the first cable, or can be tapped from the signal coupling unit. Also disclosed is a method for operating a network.
