Network component for a vehicle network and corresponding vehicle network

摘要

A network component has a signal processing device having a processor, at least one voltage source that can be connected to a supply network of the vehicle, and at least one coupling device connected to the signal processing device and the voltage source. Lines of at least one network segment of the vehicle network can be connected to the coupling device for the simultaneous signal connection of the network segment to the signal processing device and for the voltage supply of the network segment by the voltage source. The voltage source is configured such that a voltage ratio between at least one supply voltage provided by the voltage source and the voltage provided by the supply network can be selected from a selection of several predetermined voltage ratios.
